It’s taken a few extra months to get its latest 18-inch Blade laptop ready for primetime after . Those who have been waiting for the company’s latest chonkster can now order the 2024 edition of the Razor Blade 18, which starts at $3,099.
The base system comes with an i9-14900HX processor, 32GB of RAM, 1TB of SSD storage, Wi-Fi 7, a triple-fan cooling system and a six-speaker array with THX spatial audio support. On the GPU side, you can equip the laptop with up to an NVIDIA GeForce RTX 4090 (the base model has a 4070 graphics card). In what Razer claims is a first for a laptop, there’s Thunderbolt 5 connectivity, but only if you opt for a 4080 or 4090 GPU.
Razer
The display is one of the big talking points for this laptop. It comes with a QHD+ 300Hz Mini-LED display as standard. If you want higher fidelity, you can opt for a 4K 200Hz screen. The company seems to have found an extra 35 hertz since CES, since it said at the time the Razer Blade 18 would have a 4K 165Hz display option. Razer claims that this display is a world first for a laptop and it’ll set you back an extra $1,700, far more than an equivalent standalone monitor would cost. You’ll also need to wait until later this summer for a model with a 4K 200Hz panel to ship, whereas you can snag one with the QHD+ display now.
We felt that for a fully kitted-out configuration and that’s the case again this time around. Still, if you need a big-screen, high-end laptop that can run just about any program or game you can throw at it, the latest Razer Blade 18 can be all yours if you have the cash to spare.
The White House has published a policy memo asking NASA to create a new time standard for the Moon by 2026. Coordinated Lunar Time (LTC) will establish an official time reference to help guide future lunar missions. The US, China, Japan, India and Russia have space missions to the Moon planned or completed.
NASA (and the White House) aren’t the only ones trying. The European Space Agency is also trying to make a time zone outside of Earth’s… zone.
Given the Moon’s weaker gravity, time moves slightly faster there. “The same clock we have on Earth would move at a different rate on the Moon,” NASA space communications and navigation chief Kevin Coggins told Reuters.

The most error-free quantum solution yet, apparently.
What if we could build a machine working at the quantum level that could tackle complex calculations exponentially faster than a computer limited by classic physics? Despite all the heady dreams of quantum computing and press releases from IBM and Google, it’s still a what-if. Microsoft now says it’s developed the most error-free quantum computing system yet, with Quantinuum. It’s not a thing I can condense into a single paragraph. You… saw Interstellar, right?
Stability AI just unveiled Stable Audio 2.0, an upgraded version of its music-generation platform. With this system, you can use your own text to create up to three minutes of audio, which is roughly the length of a song. You can hone the results by choosing a genre or even uploading audio to inspire the algo. It’s fun — try it out. Just don’t add vocals, trust me.
Apple, hunting for its next iPhone / Apple Watch / Vision Pro (maybe?), might be trying to get into robots. According to Bloomberg’s Mark Gurman, one area the company is exploring is personal robotics — and it started looking at electric vehicles too. The report says Apple has started working on a mobile robot to follow users around their home and has already developed a table-top device that uses a robot to move a screen around.
Robot vacuums are handy little devices that can help folks save a ton of time and energy. However, some of the more well-known options are often a bit pricey, especially when a mopping function comes into the mix. As it happens, iRobot has revealed a relatively budget-friendly 2-in-1 robot vacuum and mop. It says the $275 Roomba Combo Essential actually outperforms the Roomba 600 Series thanks to 20 times more suction power, and the addition of a mop and smart navigation.
According to iRobot, this model offers 25 percent better performance at picking up dirt from hard floors than the Roomba 600 Series. It’s also said to have a longer battery life at up to 120 minutes, the ability to clean in neat rows, customizable suction and liquid settings, Clean Map reports and intelligent settings such as suggested cleaning schedules.
Although you can set up cleanings in advance, you can start one at any time with an Alexa, Siri or Google Assistant voice command. Alternatively, you can press the Clean button or tap a button in the iRobot Home app to put the device to work right away.
iRobot
The device has a four-stage cleaning system that includes adjustable suction and liquid settings, a v-shaped multi-surface brush, an edge-sweeping brush and a pump-fed microfiber mop pad. For vacuum-only operation (i.e if you’re looking to remove dirt from a rug), you’ll need to remove the mop pad first. That adds a little bit of friction to using this model. There’s another trade-off in that this isn’t a self-emptying Roomba — you’ll need to empty out the dirt storage bin manually more often.
Still, this seems like a solid Roomba at an eye-catching price. It’s available in Europe, the Middle East and Africa now, and iRobot will start selling it in the US on April 7 and Canada on April 12. The Roomba Combo Essential will reach Asia Pacific markets later this month. Folks in the US can trade in a Roomba 600 Series for a $50 credit toward a Roomba Combo Essential
In addition, iRobot is rolling out a model called the Roomba Vac Essential in North America. It has the same smart functions and other similar features as the Combo Essential, but there’s no mop. That robot vacuum will cost $250 and it’ll land in the US on April 7 and Canada on April 12.
Meanwhile, iRobot says it has reached a new milestone. Since debuting the Roomba in 2002, the company has sold more than 50 million robots.

Now’s a good time to shop if you’re looking for reliable earbuds that won’t break the bank. There’s currently a sale on Apple AirPods, including a 31 percent discount on the second-generation Apple AirPods to $89 from $129. While the second-gen Apple AirPods came out back in 2019, the entry-level option is still a great option — especially on sale.
Apple
Apple’s second-generation AirPods have an H1 headphone chip that provides a low-latency, clear sound. You can access Siri through them and control settings like pause, play and next song by double tapping one AirPod — plus customize which side does what. The second-gen AirPods hold about five hours of juice at a time and last up to 24 hours with the lightning charging case.
The entry-level AirPods are on sale alongside the third-generation Apple AirPod’s 13 percent drop to $149 from $169. The newest model’s improvements include much better audio quality and six hours of battery life (or 30 with the charging case). The second-gen AirPods Pro are marked down to $199 from $249 — a 20 percent discount. These AirPods are worth the extra cost if you want noise canceling, great sound with an H2 chip and a MagSafe USB-C charging case.
There’s a good chance you own a couple of gadgets that support wireless charging now, be it your iPhone or Android phone, wireless earbuds or smartwatch. Multi-device wireless chargers can help power them all up in one place, without the need for a bunch of cords messing up your space. There are dozens of these accessories out there today, and we’ve tested a bunch of the most popular models. You’ll find out top picks below for the best wireless charging stations, plus some advice on how to choose the right one for your needs.
Do wireless charging pads work with any phone or device?
It won’t be shocking to hear that your smartphone choice influences your choice in a wireless charger. Only iPhone owners will need to consider Apple Watch compatibility. Likewise, you’ll need an Android phone if you expect to power a Galaxy Watch. Buy an iPhone 12 or newer and you can attach your phone magnetically using MagSafe, while the latest Android phones often have some form of fast wireless charging.
However, it’s not simply a question of getting the fastest charger. You should consider what you might buy in the future. Don’t buy a two-device charger if you have an iPhone and AirPods, but have been eyeing an Apple Watch. And if you think you might switch to an Android cell phone (or vice versa), you’ll want to get something more generic that doesn’t lock you into any one ecosystem.
Some chargers include cradles, trays and other features that are heavily optimized for particular products, and might not even account for year-to-year changes. Some vertical stands are too tall for small phones like the iPhone 13 mini, for instance. While you can never completely guarantee that next year’s phone or watch will work, it’s worth buying something more likely to last.
Having said all this, don’t be afraid to get a charger with vendor-specific features if you’re fiercely loyal to one brand. Apple isn’t expected to ditch MagSafe any time soon, and Samsung will likely keep making Galaxy Watches for a while to come.
How to pick the best wireless charging pad for your needs: Location, location, location

Even without a charging cable to worry about, you’re probably buying a multi-device wireless charger with one location in mind. It might sit on your nightstand or on your desk. Not everyone buys a charger just for themselves, though; you might want to use one as a shared station for you and a partner.
If the charger will sit on your nightstand, you’ll likely want a compact, stable unit that won’t swallow all your free space or tumble to the floor (and if it does fall, one with enough durability to survive). You may also prefer a lay-flat phone pad so your screen is less likely to keep you awake. The Apple Watch and some other smartwatches can double as tiny alarm clocks, so you might want a vertical charging option for any wristwear.
At a desk, however, you may want a vertical phone stand so you can check notifications. Will the charger sit on a low table? Horizontal charger pads may make it easier to grab your devices in a hurry. Travel chargers should fold up or otherwise protect the pads while they’re in your bag. And, yes, aesthetics count. You may want something pretty if it’s likely to sit in a posh room where guests will see it.
If it’s a shared charging station, you’ll want something with multiple generic surfaces, and you’ll probably have to forgo charging more than one watch at a time. In those cases, consider the handful of 4-in-1 wireless chargers on the market, or models with USB ports.
Wireless charging speed and performance
It’s no secret that wireless charging is typically slower than wired, and powering multiple devices adds a new wrinkle. As these chargers often have to support a wide range of hardware, you’ll have to forget about the fastest, device-specific options from brands like Google, OnePlus and Samsung.
That’s not to say these will be slow, but there just isn’t much separating them on the charging speed front. As a general rule, the quickest multi-device chargers tend to top out at 15W for phones. And you’ll need an Apple MagSafe charger if you want to get that full 15W on an iPhone.
It’s rare that you’ll find a truly slow example, mind you. Even some of the most affordable options we’ve seen will recharge your phone at a reasonable 7.5W or 10W, and the 5W for other devices is more than enough. If you’re only docking overnight or while you work, speed won’t make a huge difference. Just be sure that whatever you buy is powerful enough for a phone in a case. It’s also worth noting that fast charging for other devices is rare, although you’ll occasionally find speedier options for the Apple Watch Series 7.
Quality, box contents and small details

The difference between a good charger and a great one often boils down to little details. You won’t always need to pay extra to get those, but a larger outlay may be worthwhile to avoid frustrations for years to come.
A textured surface like rubberized plastic or fabric will reduce the chances your expensive gadgets will slide off their charging points. The base should have enough grip and weight that the charger won’t easily shift out of place. Any floating or vertical stands should be sturdy — steer clear if there’s any wobble.
You’ll also want to make a note of what’s included in the box. Some chargers don’t ship with power adapters, and we’ve seen numerous models whose Apple Watch “stands” are merely holders for your existing charging puck.
Then there’s helpful touches like status lights for confirming correct placement, although you’ll want to make sure they dim or shut off after a certain amount of time. And while it’s still true that cradles and trays can limit compatibility, you do want your devices to stay where you put them. Shelves and lips can prevent your phone or watch from sliding. Oh, and be wary of floating smartwatch mounts, as heavier timepieces might sag.
Belkin
It doesn’t get much better than Belkin’s most advanced model of wireless charger if you’re an Apple devotee. The high-quality BoostCharge Pro 3-in-1 pad offers 15W MagSafe charging for your iPhone, fast charging for the Apple Watch and a space for AirPods Pro or other earbuds with Qi-compatible cases. The base is weighty, covered in rubberized plastic and includes a discreet status light for your earbuds. More importantly, it supports more devices than you might think. Although the Pro pad uses MagSafe, the horizontal layout lets you charge virtually any phone at reduced speeds. We also have to give Belkin kudos for one of the most convenient Apple Watch chargers we’ve seen. It not only works horizontally and vertically, but includes a knob to adjust for different sizes and third-party cases.
This is quite large compared to some 3-in-1 chargers, so it’s not the greatest choice for a nightstand. Consider the smaller footprint of its counterpart, the BoostCharge Pro 3-in-1 Wireless Charger with MagSafe 15W, if you have an iPhone 12 or newer. You also won’t find USB ports, and the indented earbud pad rules out a second phone. Still, it’s easily worth the $150 asking price.
Pros
Supports three devices at once
Supports 15W MagSafe charging for iPhones
Can adjust to support different Apple Watch models
There are many quality high-end chargers to choose from, but Logitech’s Powered 3-in-1 Dock offers a few features that help it rise above. It consumes relatively little space, and the rubberized horizontal and vertical chargers deliver up to 10W while gripping your devices tightly, so both you and your partner can top off.
It has a few limitations, though. The vertical stand isn’t well-suited to the iPhone 13 mini and other small phones. And while the floating stand works with most Apple Watches, heavier ones tend to sag (such as this author’s steel Series 5 with a Leather Link strap) and might not charge properly. If those aren’t issues, though, your $130 will be well-spent.
Pros
Compact design
Supports three devices at once
Vertical spot supports up to 10W of power delivery
You can find plenty of more affordable 3-in-1 chargers. Few, however, offer quite as much for the money as the Anker 533 Wireless Charger Stand. It offers an adjustable-angle 10W vertical stand and lets you charge an Apple Watch either horizontally or vertically. There’s also a 20W USB-C power adapter in the box, so you won’t have to buy an aftermarket brick (or rely on proprietary cabling) to get started.
The limitations mostly stem from the cost-cutting measures. You probably won’t have room for a second phone. And like some chargers we’ve seen, the Apple Watch mount is a bring-your-own-cable affair that only supports older USB-A connections. The included cable with your Series 8 or SE won’t work here. At $58, though, this 3-in-1 wireless charging stand is a good bargain.
If you’re willing to spend a bit more and live in Apple’s universe, the Otterbox 3-in-1 Charging Station for MagSafe is worth your attention. The extremely small footprint of this wireless charger is ideal for nightstands. You can tuck a trio of your phone, earbuds and Apple Watch into an area normally reserved for a single device. The company supplies a surprisingly powerful 36W USB-C power adapter in the box that serves as a fast wired option in a pinch.
The caveats are clear. The floating magnetic charger rules out Android phones and older iPhones. You’ll need to bring your own Apple Watch cable, and the USB-A port won’t work with the USB-C cables bundled with newer watches. The horizontal-only watch mount also rules out clock functionality. The overall balance of space and utility is still difficult to top for $80.
Pros
Compact design
Supports three devices at once
Includes a 36W USB-C power adapter in the box
Cons
Floating MagSafe spot doesn’t work with older iPhones and Android phones
The 2-in-1 field is highly competitive and makes it difficult to choose an absolute winner. However, Mophie’s Dual Wireless Charging Pad hits many of the right marks. It can charge two Qi-certified devices at up to 10W each, making it a great pick for a two-phone household. The fabric surface with rubberized trim should keep your gadgets steady, and the status lights will confirm accurate placement. There’s even a USB-A port to plug in your watch charger or any other wired hardware.
The complaints are few. You won’t charge at 15W, and we’d rather have USB-C than USB-A. It’s nonetheless a safe choice at $80, and worth buying over less expensive options.
Pros
Can charge two devices simultaneously, both with 10W
Multi-device chargers from phone manufacturers tend to be either compromised or highly proprietary, but Samsung’s Fast Charger Duo (sometimes known as the 15W Duo Fast Wireless Charger) bucks that trend. It’s compact and delivers high-speed charging for one phone and an accessory, whether it’s a Samsung Galaxy Watch or another manufacturer’s earbuds. The status lights will even dim at night, and change color to indicate when your batteries are full.
This won’t help for two-phone households, and Samsung only guarantees 15W charging for some of its own phones (the Galaxy Note 10, Galaxy S20 and later). You’ll also want to be mindful of which version you buy, as there are variants with and without a power adapter in the box. Neither is cheap at respective prices of $90 and $70. This remains an elegant charger for nightstands and travel, though, and the pads are sufficiently device-agnostic.
Pros
Supports 15W charging
Compact design
Cons
Power adapter included only with certain variations
There are few wireless chargers built with more than one person in mind, but Mophie’s 4-in-1 Wireless Charging Mat is the most well-rounded of the bunch. The pad can handle up to four devices wirelessly at 10W, including two phones and two accessories. There’s also a spare USB-A port for charging earlier Apple Watch models (using the included mount and your own cable) or wired items. A fabric surface, subtle device trays and indicator lights will also take the mysteries out of charging.
This is a giant charger compared to most, and you might find it limiting if your home has more than one Apple Watch or accessories that won’t fit the smaller charging pads. Even so, Mophie is offering considerable value for $150. The 4-in-1 does more than some 3-in-1 chargers at that price, and it doesn’t suffer the compatibility issues of rivals like Nomad’s Base Station Pro.
Pros
Supports up to four devices at once
Attractive design with indicator lights make it easy to use
These days, the best gaming TVs are really no different from the best TVs you can buy in general. That said, there are a few key features to keep in mind when looking for a set to get the most out of your PlayStation 5 or Xbox Series X/S. No, you don’t need a fancy TV to simply enjoy a video game, but a good screen can only make the experience more enjoyable. If you’re unsure where to start, we’ve laid out some helpful advice for buying a good gaming TV and noted a few well-reviewed examples you can buy today, at various price points.
What to look for in a gaming TV
Whether you use it for gaming or not, all good TVs are built on the same foundations. You want a 4K resolution, sufficient brightness, high contrast ratios with deep and uniform black tones, colors that find the right balance between accuracy and saturation, and wide viewing angles. For video games specifically, you want a TV with minimal input lag and fast motion response, with no blur or other unwanted artifacts behind quick-moving objects. Of course, finding a set that has all of these gaming features and fits into your budget can be tricky.
For now, a top OLED TV will offer the best picture quality for gaming or otherwise. But good OLED TVs usually cost more than their LCD counterparts, and some OLED sets may not get bright enough for those who have their TV set in a particularly well-lit room. If you opt for an LCD TV, an advanced backlight with mini LEDs and effective full-array local dimming will usually improve contrast and lighting detail, while a quantum dot filter can enhance colors.
One thing you don’t need to worry about is 8K support. Although the PS5 and Xbox Series X are technically capable of outputting 8K video, very few games are made for that resolution, and 8K’s practical benefits are extremely minimal unless you plan on sitting unreasonably close to a massive TV. The few 8K TVs on the market are also very expensive.
All that said, there are a few terms you should particularly look out for when buying a TV for your new game console or high-end graphics card.
HDMI 2.1
To get the most out of a PlayStation 5 or Xbox Series X/S, your TV should have full HDMI 2.1 support. This is the latest major update to the HDMI spec, enabling a higher maximum bandwidth — 48 gigabits per second, up from HDMI 2.0’s 18 Gbps — and a handful of features that are beneficial for gaming performance specifically. These include variable refresh rate (VRR) and automatic low latency mode (ALLM), which we detail further below.
Beyond that, perhaps the chief perk of HDMI 2.1 is its ability to transmit sharp 4K video up to a 120Hz refresh rate with modern consoles like the PS5 and Xbox Series X, or up to 144Hz with a powerful gaming PC. Not every PS5 or Xbox Series X/S game supports frame rates that high — and some only do at lower resolutions — but those that do will look and feel especially fluid in motion. HDMI 2.1 also includes support for Enhanced Audio Return Channel (eARC), which allows you to pass higher-quality lossless audio from a source device connected to the TV to a compatible soundbar or receiver.
The more full HDMI 2.1 ports your TV has, the better. “Full” is the key word there. As reported by TFT Central, because HDMI 2.1 is backwards compatible with HDMI 2.0, TV and monitor manufacturers have been allowed to brand HDMI ports as “HDMI 2.1” even if they lack full (or any) support for the spec’s upgraded features. We recommend a few TVs below that have true HDMI 2.1 ports, but if you’re buying a new TV for gaming, make sure your chosen set isn’t trying to hide any capabilities you may consider essential.
HDR — High Dynamic Range
HDR refers to a TV’s ability to display a wider range between the darkest and brightest parts of a picture. This broader range can bring out details that would otherwise be missing on a standard dynamic range (SDR) TV, in both the very dark and, especially, the very bright areas of an image. HDR typically comes with an improvement to color reproduction as well, displaying a larger palette of more vibrant colors that brings content closer to its creator’s original vision.
To get an HDR picture, you need both content that is mastered to take advantage of the tech and a TV capable of displaying that content. HDR also comes in a variety of formats, which are generally split between those that utilize static metadata (e.g., HDR10) and those that utilize dynamic metadata (e.g., HDR10+, Dolby Vision). In short, the latter allows a TV to optimize its brightness and colors on a per-scene or even per-frame basis, while the former uses one set of optimized settings for the entirety of the given content. Support for these formats can differ depending on the TV, content and game console you use. The Xbox Series X and S, for example, support Dolby Vision for gaming, while the PS5 does not.
The good news is that most TVs you’d buy in 2023 are HDR-ready in some fashion, even on the budget end of the market. The catch is that some TVs are much better at getting the most out of HDR than others. The same goes for actual content mastered in HDR. With video games in particular, there aren’t quite as many titles designed to take advantage of HDR as there are movies (though the number is growing all the time), and the variance in HDR quality tends to be wider.
HGiG — HDR Gaming Interest Group
HGiG stands for the HDR Gaming Interest Group. Sony and Microsoft are both members, as are many TV makers and game developers. What this means is that, ideally, all the groups communicate information so that you can start up a new game on a console or PC and have it automatically recognize your display. Once that happens, the game can adjust the internal settings to adjust for that display’s capabilities and give you the best picture quality possible, without losing details in the brightest or darkest areas of the screen. For example, daylight at the end of a dark tunnel may portray a brightly lit environment instead of looking like an overexposed white blob.
This is a good thing, but the reality is a bit more complicated. Not all TVs highlight HGiG compatibility in their settings menu, while only some PlayStation and Xbox games recognize and follow the guidelines. If an HGiG option is listed in your TV’s tone mapping settings, you should turn it on prior to running the console’s HDR settings. Then, if you’re playing a game that supports HDR and HGiG, you should be in good shape without having to adjust the various luminance levels again. Still, how all of this looks to you might differ depending on your TV and the game you’re playing. Owners of certain LG OLED TVs, for instance, may prefer their TV’s Dynamic Tone Mapping setting. Use whatever settings you think look best.
ALLM — Auto Low Latency Mode
ALLM allows a source (like your PS5 or Xbox) to tell the display to switch into a picture mode that reduces lag between receiving each frame of an image and displaying it on the TV. This cuts out additional processing that could be the milliseconds of difference between landing a precise input or not. A good modern TV can automatically switch to game mode, then back out when you’d rather watch a movie or TV show.
VRR — Variable Refresh Rate
VRR will sound familiar if you’re a PC gamer. Most players have experienced slowdown, screen tearing or stuttering as a system struggles to render each frame at the target speed, which is most commonly 30 or 60 fps on a TV. With VRR, everything stays in sync: Your display won’t show the next frame until it’s ready, which can make things feel smoother and more responsive, even if the system fails to deliver on its target frame rate.
There are a few different implementations of VRR available, including Nvidia’s G-Sync, AMD’s FreeSync and the HDMI Forum’s VRR spec, which is part of the full HDMI 2.1 standard. Both a TV and an input device need to support the same VRR tech for it to work, and different devices may only support VRR within a specific refresh rate window. On a 120Hz display, for instance, the PS5’s VRR only works between 48Hz and 120Hz.
As a reminder, the PS5 supports HDMI Forum VRR, the Xbox Series X/S support HDMI Forum VRR and FreeSync, while gaming PCs may support G-Sync or FreeSync depending on whether they use a Nvidia or AMD graphics card. A great gaming TV supports all the big VRR formats, but missing, say, G-Sync, isn’t a killer if you only game on a PS5 or Xbox.
Good gaming TVs you can get right now
The likes of Samsung, LG, TCL, Vizio and Hisense have unveiled new TVs for 2024 but, as of this writing, we’ve only recently started to see the first few of those become available. Details for more new models should be confirmed in the coming weeks. If history is any indication, though, most of those sets are unlikely to be game-changing upgrades over the 2023 models still on sale today, and they’ll cost more out of the gate. We’ll have to see if there are exceptions, of course: Samsung’s new S95D OLED TV now uses anti-glare technology, for instance, while Hisense promises improved brightness across its new midrange sets. If you want the latest and greatest and are willing to pay more to get it, hold out for a little longer.
But the TV market is always in motion. Most of the best models from last year have steadily fallen in price since launch, and they should only drop further as manufacturers look to clear out inventory. This means that, in most cases, buying a good 2023 TV should continue to provide the most bang for your buck, at least for the near term. Those are the sets we’ve highlighted with our recommendations below. While we at Engadget do not formally review TVs, we’re confident in our picks after thoroughly researching user feedback and the consensus from other professional review sites we trust, such as Rtings, Wirecutter, Reviewed and PCMag, among others.
The Samsung S90C has a QD-OLED display that combines an OLED panel with a layer of quantum dots. This allows it to display the high contrast and deep blacks of any good OLED TV without sacrificing as much in the way of peak brightness or color saturation. It should deliver consistently smooth motion, and it has four HDMI 2.1 ports that can play up to 4K 144Hz. It also supports HDR10 and HDR10+, ALLM and the major VRR formats. Sizes range from 55 to 83 inches. Like the rest of Samsung’s TV lineup, however, it doesn’t work with Dolby Vision HDR.
We’ll also note the Samsung S95C, a higher-end model. It, too, can play in 4K up to 144Hz, and some reviewssay it can get a bit brighter than the S90C in HDR. Since it runs its ports through an external box, its actual hardware is thinner as well. But it’s significantly more expensive, so it’s harder to justify unless money is no object. The aforementioned S95D OLED TV, Samsung’s flagship for 2024, may be a more meaningful upgrade, though it’s only just become available and costs even more.
The LG C3’sWOLED panel can’t get as bright as a QD-OLED TV like the Samsung S90C, but it still performs excellently in terms of contrast, input lag, motion response and viewing angles. It’s occasionally available for a little bit less than the S90C, too. It follows the HGiG’s HDR guidelines, supports ALLM, works with all the major VRR formats and has four full HDMI 2.1 ports capable of outputting 4K 120Hz with a PS5, Xbox or PC. It also supports all the major HDR standards, including Dolby Vision, and it’s available in a wide variety of sizes, from 42 to 83 inches. It’s just less ideal in a brightly-lit room, and it doesn’t support a 144Hz refresh rate for those who may want to get the most out of a gaming PC.
Screen sizes: 43″, 50″, 55″, 65″, 75″, 85″ | Display type: QLED with mini-LED backlight (VA panel on 43″ and 50″, ADS panel on 55″ and up) | Resolution: 4K | Maximum refresh rate: 120Hz (144Hz on 43″ and 50″) | HDR formats: HDR10, HDR10+, HLG | HDMI ports: 4x HDMI 2.1 | VRR: HDMI Forum VRR, FreeSync Premium Pro, G-Sync compatible | Smart OS: Tizen | Screen form: Flat | ALLM: Yes | TV tuner: ATSC 3.0
If you need the improved brightness of a LCD TV, or if you think you might play one game (extremely) long enough to worry about burn-in, consider the Samsung QN90C. It can’t match the contrast, response time or viewing angles of a good OLED model, but its mini-LED backlight and quantum-dot color should make for a richer image than most LCD TVs, particularly in HDR. Its motion and input lag shouldn’t cause problems either, and it can get much brighter than the models mentioned above. It still doesn’t support Dolby Vision, but it has four full HDMI 2.1 ports, ALLM and all the big VRR formats. It also comes in several screen sizes, with the 43- and 50-inch models capable of hitting a 144Hz refresh rate. The rest go up to 120Hz, which is the max for a PS5 or Xbox Series X/S. The 43- and 50-inch versions of these TVs use VA panels, though, which should result in better contrast but worse viewing angles.
The Sony X93L is anotherhighly-ratedpremium LED TV that does support Dolby Vision, albeit at 60Hz only, and can auto-calibrate HDR on a PS5. It has two fewer HDMI 2.1 ports than the QN90C, however, which makes it a tighter fit for those with multiple gaming devices, and its size range starts at 65 inches.
Screen sizes: 55″, 65″, 75″, 85″, 100″ | Display type: QLED with mini-LED backlight (ADS Pro panel on 75″, VA panel on others) | Resolution: 4K | Maximum refresh rate: 144Hz | HDR formats: Dolby Vision, HDR10, HDR10+, HLG | HDMI ports: 2x HDMI 2.1, 2x HDMI 2.0 | VRR: HDMI Forum VRR, FreeSync Premium Pro, G-Sync compatible | Smart OS: Google TV | Screen form: Flat | ALLM: Yes | TV tuner: ATSC 3.0
The TVs above are all pretty expensive. If you’re on more of a budget, the Hisense U8K, another QLED TV with mini LEDs, should be a strong value. It may not be a better gaming TV than the QN90C in a vacuum, as it only has two full-fat HDMI 2.1 ports, and its image will wash out more dramatically when viewed from an angle. But reviewssuggestthat, for a few hundred less, it’ll still look good in any lighting environment, with impressive brightness levels, 4K 144Hz support, all the main HDR formats, VRR, ALLM and low-enough input lag in game mode. You’ll still sacrifice contrast compared to a good OLED TV, however, and motion won’t look quite as fast or smooth.
The TCL QM8lookstobe an impressive QLED option in this price range as well. It can get a little brighter than the U8K and supports up to a 144Hz refresh rate in 4K or a super-fast 240Hz in 1080p. Unlike the Hisense model, it also keeps its eARC port separate from its two HDMI 2.1 ports, which means you could keep a PS5, Xbox Series X and eARC-compatible soundbar hooked up and optimized without ever having to mess around with inputs. Its smallest size is 65 inches, though, and a few reviews say it’s a bit worse than the U8K at upscaling lower-resolution content, which may affect those looking to play retro consoles.
If you want to pay a little less, meanwhile, the Hisense U7K offers a similar set of gaming features as its higher-end sibling but isn’t as bright or vivid.
Screen sizes: 55″, 65″, 75″ | Display type: QLED with mini-LED backlight | Resolution: 4K | Maximum refresh rate: 60Hz | HDR formats: Dolby Vision, HDR10, HDR10+, HLG | HDMI ports: 4x HDMI 2.0 | VRR: HDMI Forum VRR, FreeSync compatible, G-Sync compatible | Smart OS: Google TV | Screen form: Flat | ALLM: Yes | TV tuner: ATSC 1.0
On the lower end of the price spectrum, the Hisense U6K is the rare budget-level TV with quantum-dot color, a mini-LED backlight and full-array local dimming. Variousreviewssayall of this helps it deliver better contrast and color volume than most value-oriented models. ALLM and the major HDR standards are supported as well. Technically, it’s also a VRR display — but, like many cheaper TVs, the U6K is limited to a 60Hz refresh rate, so that support only goes so far. There are no HDMI 2.1 ports either, and the TV’s brightness levels and motion handling will still be a clear step down from more expensive options. But at $350 or so for a 55-inch model, those issues should be easier to overlook.
The TCL Q5 is another notable budget option, as it’s one of the few cheap TVs that can play up to 120Hz, albeit only at a 1080p or 1440p resolution. It lacks a local dimming feature and the U6K’s mini- LED backlight, but for competitive-minded gamers who are willing to trade some sharpness and picture quality for a more responsive image, it could be a decent value. The same sentiment should apply to the TCL Q6, which offers slightly higher brightness levels but costs a bit extra.
On Tuesday, The White House published a policy memo directing NASA to create a new time standard for the Moon by 2026. Coordinated Lunar Time (LTC) will establish an official time reference to help guide future lunar missions. It arrives as a 21st-century space race emerges between (at least) the US, China, Japan, India and Russia.
The memo directs NASA to work with the Departments of Commerce, Defense, State, and Transportation to plan a strategy to put LTC into practice by December 31, 2026. International cooperation will also play a role, especially with signees of the Artemis Accords. Established in 2020, they’re a set of common principles between a growing list of (currently) 37 countries that govern space exploration and operating principles. China and Russia are not part of that group.
“As NASA, private companies, and space agencies around the world launch missions to the Moon, Mars, and beyond, it’s important that we establish celestial time standards for safety and accuracy,” OSTP Deputy Director for National Security Steve Welby wrote in a White House press release. “A consistent definition of time among operators in space is critical to successful space situational awareness capabilities, navigation, and communications, all of which are foundational to enable interoperability across the U.S. government and with international partners.”
Einstein’s theories of relativity dictate that time changes relative to speed and gravity. Given the Moon’s weaker gravity (and movement differences between it and Earth), time moves slightly faster there. So an Earth-based clock on the lunar surface would appear to gain an average of 58.7 microseconds per Earth day. As the US and other countries plan Moon missions to research, explore and (eventually) build bases for permanent residence, using a single standard will help them synchronize technology and missions requiring precise timing.
“The same clock that we have on Earth would move at a different rate on the moon,” NASA space communications and navigation chief Kevin Coggins toldReuters. “Think of the atomic clocks at the U.S. Naval Observatory (in Washington). They’re the heartbeat of the nation, synchronizing everything. You’re going to want a heartbeat on the moon.”

The White House wants LTC to coordinate with Coordinated Universal Time (UTC), the standard by which all of Earth’s time zones are measured. Its memo says it wants the new time zone to enable accurate navigation and scientific endeavors. It also wants LTC to maintain resilience if it loses contact with Earth while providing scalability for space environments “beyond the Earth-Moon system.”
NASA’s Artemis program aims to send crewed missions back to the Moon for the first time since the Apollo missions of the 1960s and 70s. The space agency said in January that Artemis 2, which will fly around the Moon with four people onboard, is now set for a September 2025 launch. Artemis 3, which plans to put humans back on the Moon’s surface, is now scheduled for 2026.
In addition to the US, China aims to put astronauts on the Moon before 2030 as the world’s two foremost global superpowers take their race to space. Although no other countries have announced crewed missions to the lunar surface, India (which put a module and rover on the Moon’s South Pole last year), Russia (its mission around the same time didn’t go so well), the United Arab Emirates, Japan, South Korea and private companies have all demonstrated lunar ambitions in recent years.
In addition to enabling further scientific exploration, technological establishment and resource mining, the Moon could serve as a critical stop on the way to Mars. It could test technologies and provide fuel and supply needs for eventual human missions to the Red Planet.
You don’t need to shell out a four-figure sum to find a great smartphone. In fact, you don’t even need to spend half of that to snap up one that covers all of the basics and then some. At its regular price of $300, was already our pick for the around. It’s currently on sale for $250 ($50) off, which makes it an even better deal. That’s close to a record low price. The discount is part of a broader sale on .
OnePlus
Our pick for the best cheap smartphone is currently $50 off its usual price.
The OnePlus Nord N30 5G offers great value however you slice it. The phone has a relatively zippy Snapdragon 695 5G processor, along with 8GB of RAM and 128GB of storage, which is expandable with a microSD card.
You’ll get a 16MP front-facing camera and, on the rear, 108MP main and 2MP macro lenses. The 5,000mAh battery should last you a day of moderate use, while OnePlus says the 50W fast charging support will top it up from a one-percent charge to 80 percent in 30 minutes. The OnePlus Nord N30 5G also has a 6.7-inch, 120Hz IPS display that’s great for gaming.
On the downside, there’s no IP rating for dust or water resistance. And while the handset runs on Oxygen OS 13.1 (which is based on Android 13), OnePlus has only committed to bringing one major Android update to the N30, along with three years of security support. That’s a pity for those looking for something that’ll stay up to date for a few years without breaking the bank, but that level of Android support is typical for budget phones.
While classical computers and electronics rely on binary bits as their basic unit of information (they can be either on or off), quantum computers work with qubits, which can exist in a superposition of two states at the same time. The trouble with qubits is that they’re prone to error, which is the main reason today’s quantum computers (known as Noisy Intermediate Scale Quantum [NISQ] computers) are just used for research and experimentation.
Microsoft’s solution was to group physical qubits into virtual qubits, which allows it to apply error diagnostics and correction without destroying them, and run it all over Quantinuum’s hardware. The result was an error rate that was 800 times better than relying on physical qubits alone. Microsoft claims it was able to run more than 14,000 experiments without any errors.
According to Jason Zander, EVP of Microsoft’s Strategic Missions and Technologies division, this achievement could finally bring us to “Level 2 Resilient” quantum computing, which would be reliable enough for practical applications.
“The task at hand for the entire quantum ecosystem is to increase the fidelity of qubits and enable fault-tolerant quantum computing so that we can use a quantum machine to unlock solutions to previously intractable problems,” Zander, wrote in a blog post today. “In short, we need to transition to reliable logical qubits — created by combining multiple physical qubits together into logical ones to protect against noise and sustain a long (i.e., resilient) computation. … By having high-quality hardware components and breakthrough error-handling capabilities designed for that machine, we can get better results than any individual component could give us.”
Microsoft
Researchers will be able to get a taste of Microsoft’s reliable quantum computing via Azure Quantum Elements in the next few months, where it will be available as a private preview. The goal is to push even further to Level 3 quantum supercomputing, which will theoretically be able to tackle incredibly complex issues like climate change and exotic drug research. It’s unclear how long it’ll take to actually reach that point, but for now, at least we’re moving one step closer towards practical quantum computing.

If you’ve yet to join the VR craze of the last few years, then now’s a good time to do so. The 128GB Meta Quest 2 is currently available at Walmart for $199, down from $249 — a return to its record-low price. Not only is the sale enticing, but the deal comes with a $50 credit for the Meta Quest store. Amazon is offering the same 20 percent discount on the Meta Quest 2, but it doesn’t include that extra credit.

The Meta Quest 2 might not be the newest headset in its lineup, but it still has plenty of great features — and is our pick for 2024’s best cheap VR headset. Plus, we gave it an 89 in our review back in 2020, when it was still called the Oculus Quest.
The device is wireless, comfortable and much more affordable than the alternatives. Its field of vision is about 90 degrees and can change based on which face pads you use. The Meta Quest 2 also offers fast-switching LCDs, an 1832×1920 resolution and a 90Hz refresh rate. You can hook it up to your gaming PC or explore the many titles available on Meta’s Quest store — especially with $50 to spend.
