How to enable 4K display resolution in Samsung DeX

[ad_1]

Samsung DeX was introduced in 2017. Many years later, it continues to be the best way to enjoy a desktop-like experience via a smartphone or tablet. All modern flagship Galaxy phones and tablets support Samsung DeX, and Samsung continually makes improvements to the feature from time to time.

However, there is room for further improvement as DeX has a not-so-small list of limitations. One major limitation is the lack of support for 4K resolution.

Samsung DeX can project its desktop interface to external displays in multiple ways. You can connect wirelessly to any TV or monitor via Miracast screen mirroring (most smart TVs have this) or use a USB-C to HDMI cable. You can also use DeX on a Windows PC by connecting your device to it with a USB cable.

When you connect to a display using a USB-C to HDMI cable, DeX allows you to change the screen resolution. But the maximum supported resolution is WQHD (2560×1440). You can even be limited to 1080p depending on the TV you own, as televisions are generally designed to run at either 1080p or 4K and don’t support WQHD and other intermediate resolutions.

If that’s something that bothers you, don’t worry, Samsung’s Good Lock app can help. Good Lock enables many hacks and experimental functionalities that aren’t officially supported on One UI. One of those lets you enable higher resolutions in DeX.

For those wishing to run DeX at 4K resolution on their monitor or TV, we have prepared the guide below. It applies to both direct HDMI connections between the phone/tablet and display and connections made via a DeX dock, such as the one Samsung used to sell a few years ago.

First, download and install Good Lock and MultiStar

If Good Lock is available in your country, you can install it directly from the Galaxy Store. Once installed, open Good Lock and install MultiStar from the app’s Life up tab. Then, skip to the next section of the guide to find out how you can use MultiStar to enable 4K resolution in DeX.

If Good Lock isn’t available in your country, follow the steps below to manually download and install Good Lock and MultiStar before moving into the next section.

Step 1. First, let’s download and install Good Lock. Click this link in your mobile browser to open the Good Lock APKMirror page. On that page, scroll down to the All Versions section and hit the download button next to the latest version of the app.

Step 2. Scroll down to the Download Good Lock section and tap the download icon (highlighted in the screenshot below) once again.

Step 3. Scroll down once again and hit the DOWNLOAD APK button and the APK file should start downloading in a few seconds.

Step 4. Once the APK file is downloaded, open the My Files app on your device. The downloaded Good Lock file will show in the list of recent files at the top of My Files – tap it and follow the on-screen instructions to install the app.

Note: If you are installing an app manually for the first time, you will get a pop-up notification saying “your phone currently isn’t allowed to install unknown apps from this source.” To fix that, simply tap the Settings button on the pop-up notification, then tap the toggle button next to Allow Permission. 

Step 5. Now, it’s time to get MultiStar. Click this link to visit the MultiStar APKMirror page and then perform the same steps as you did earlier for Good Lock to download and install the latest version of MultiStar.

Enable and activate 4K resolution in DeX

Once you have Good Lock and MultiStar installed, follow the steps below to enable 4K resolution.

Step 1. Open Good Lock, switch to the Life up section of the app, and tap MultiStar to open it. 

Step 2. In MultiStar, tap I ♡ Samsung DeX, which is the very first option.

Step 3. In the I ♡ Samsung DeX menu, enable the High resolutions for external display option.

Step 4. Connect your phone or tablet to the display using an HDMI cable to fire up DeX mode, then open the Settings app via the app drawer or the shortcut on the DeX desktop.

Enable 4K display resolution in Samsung DeX

Step 5. Select Samsung DeX to view all DeX settings.

WhatsApp will finally let you select HD as default image resolution

[ad_1]

Last updated: March 26th, 2024 at 09:12 UTC+01:00

WhatsApp compresses all the images and videos unless you share them as documents. And many people get annoyed by the drop in quality of images and videos shared through WhatsApp. Last year, the app introduced the ability to share HD (actually 4K resolution) quality media, but you have to explicitly select that option. If you are tired of selecting the HD option every time, you might be in for a treat.

WhatsApp to bring the ability to select HD quality as the default resolution setting for sending images and videos

The Meta-owned company is working on a feature that lets you choose the default image and video quality for all your messages. WABetaInfo has found that WhatsApp is testing an option in the app’s Storage And Data settings that lets you choose between ‘Standard’ and ‘HD’ quality for all the images and videos that you share. This feature has been found in the 2.24.5.6 version of WhatsApp for Android.

WhatsApp Android 2.24.5.6 HD Images Quality Settings

After thorough testing is done, WhatsApp could release this feature to all Android users. You can expect to see this option on your Galaxy (or any other Android) device in the coming months.

Right now, when you share images and videos, you have to select the HD option every single time if you want to share higher-quality media. Many normal users don’t even know that this option exists, so many images and videos aren’t even shared in HD quality by default. Once this feature is released the usage of HD quality might increase and it will make it easier to send higher-quality media for those who want to use it.

14K Resolution 3D printer unveiled : Nova 3D Whale Ultra

high-resolution 3D printer Nova 3D Whale Ultra

When it comes to the world of 3D printing, the Nova 3D Whale Ultra 14K printer has been making waves with its promise of a large build area and the potential for high-resolution output. For those in the market for a new 3D printer, it’s worth taking a closer look at what this machine has to offer and whether it truly meets the needs of a demanding printing environment.

The Nova 3D Whale Ultra 14K boasts a build volume that measures 223 x 126 x 250 mm, which is quite spacious for those tackling big and intricate projects. The standout feature of this printer is its advertised 14K resolution, which suggests it can produce prints with extremely fine detail. However, some experts in the field, like Ross from Fire Hammer Videos, have raised concerns about whether this printer actually delivers a noticeable improvement over 8K printers, questioning the authenticity of the 14K resolution claim.

14K Resolution 3D printer

Navigating the manufacturer’s website to find information about the various models can be a bit of a challenge due to its confusing layout. Once you do find the right model, you’ll see that the printer comes with a built-in heater. This heater is meant to improve print quality by maintaining a consistent temperature. But there’s some doubt about how well it works, as it doesn’t always operate as expected, which could affect the outcome of your prints.

14K Resolution 3D printer

Here are some other articles you may find of interest on the subject of  3D printing :

The design of the printer is straightforward and functional. It features a sturdy ball screw to move the print bed smoothly, and the resin vat is large, capable of holding more than a liter of resin. It even has a handy resin refill feature. These are positive points for those who value efficiency and reliability in their printing processes.

On the downside, the user interface (UI) could be a stumbling block for many. It’s been described as not very user-friendly and suffers from poor translation, which can lead to frustration and wasted time. The touch screen is also not capacitive, meaning it may not always register your touches, potentially disrupting your workflow.

After a print job is completed, the printer automatically deletes the file and asks you to clear the vat. This might be inconvenient for users who need to do multiple prints of the same file. Having to reload the file and clear the vat after each print could be seen as a step back in terms of user convenience.

Specifications :

  • Product Size：341*312*580mm
  • Package Size：435*400*690mm
  • Package Weight：20kg
  • Printing Volume：223*126*250mm
  • LCD Resolution:13312*5120px
  • Technology：LCD MSLA
  • XY Resolution: 16.8*24.8μm
  • Z-axis：Ball screw and double 15CA linear guide
  • Resin Heating System：Yes
  • Auto-feeding System：Yes
  • Light Source：5th Generathion COB light sourc
  • Light Intensity:4500uW/cm2
  • Printing speed: ≤70mm/h,
  • File Transfer：USB drive, WiFi，RJ45 cable
  • Software System:windows7(64 bit）and above
  • Slicing Software: Chitubox; Novamaker,Voxel dance Tango
  • UI Operation：4.3inch IPS Touch screen
  • File Format：.stl, .obj
  • Layer Height：0.02-0.16mm
  • Voltage：110/220V(Depends on the voltage in your area)

It appears that after taking everything into account, the Nova 3D Whale Ultra 14K printer is a mixed bag. It has a generous build area and a resin refill system, as well as a solid mechanism for moving the print bed. But it’s let down by its user interface, the performance of the built-in heater, and questions surrounding the true resolution it can achieve.

The design and features of the printer could use some improvement. As it stands, the Whale Ultra 14K has potential, but whether it can live up to that potential in actual use is another matter. Those considering this printer should weigh its pros and cons carefully before deciding to invest.
