Windows 10: Asus 4K PA279CV Display Is Ok With 2 Displays But Goes Black By Itself

Initially 4K monitor was working fine on Win11 Home then went black after logon. Pressing Ctl-Alt-Delete many times brings up a dialog to goto Task Mgr or Switch User etc.Thinking it was a power up problem, I tried repairing Win then Restore then Recovery. In exasperation I reinstalled Win, only to get the same result. I switched to a 1080p monitor and everything was fine! Hooked up the 4K as a second monitor and worked ok too. Turning off 1080p then 4K goes black again.The displays are driven by internal Intel 630 graphics on an Acer TC-885-EB17, no graphics card. Also Asus PA279CV driver was

4K Display Issues

I am in the process of installing Applications on my New ASUS Notebook PC Model Q535UD with a 15.6 inch 4K UHD (Ultra High Definition) screen - 3840x2160 pixels.

While installing applications (for example, HP 8640 Printer Assistant, Adobe Photoshop Elements 2018) I encountered displays issues (compared to standard displays on my other PCs).

These issues include small font as well as compressed (or small) icons. I have tried "combability" settings without success. I do not want to resolve this issue with a global setting that affect all displays.

I have also conferred with other 4K users and they all report similar issues.

Any suggestions - is there a forth coming fix for these issues?

 

Issue with black screen, dual display, ATI Integrated GPU

Hi,

I suggest you to follow the below methods and check if it helps.

Method 1: I suggest you to go to device manager and disable the display drivers, check whether the issue persists or not.

• Press Windows + X keys and click
  Device manager.
• Click to expand Display adapters, right click the second adapter and click
  Disable.
• Restart the computer and check whether the issue persists or not.
• Repeat the same steps to disable the first display adapter and check if it helps.

If you find the issue is with anyone of the display adapters then, I suggest you to update the display drivers from the manufactures website for Windows 10 and check if it helps.

Method 2: I suggest you to follow the steps form the below article for
“Black Screen” issues and check if it helps.

4K display screens...

Hi,

The screen resolution of a display determines how much information is displayed on the screen. It is measured horizontally and vertically in pixels. At lower screen resolutions, such as 640 x 480, fewer items will fit on the screen, but they will appear
larger. At higher resolutions, such as 1900 x 1080, more items will fit on the screen but they will appear smaller. The resolution modes will vary with each display based on the video card device, monitor size, video driver, and monitor driver.

Windows 10 includes support for 4K and 8K displays.

By default, Windows chooses the best display settings for your PC based on your monitor. If you like, you can manually change the screen resolution of each display on your PC separately to what you want.

[*]Driver updates for Windows 10 and many devices (such as monitors, printers and video cards) are automatically downloaded and installed via Windows Update.
[*]While it’s likely that you already have the most recent driver, if you’re having trouble with a device, you can try fixing it by updating or reinstalling the driver. Here’s how:

[*]

[*]

• • 
    Select the Start button, type Device Manager, then select it from the list of results.
  • 
    Expand one of the categories to find the name of your device, then right-click (or tap and hold) it, and select
    Update Driver Software.
  • 
    Select Search automatically for updated driver software.
  • 
    If Windows doesn’t find a new driver, you can try looking for one on the device manufacturer’s website and follow their instructions.

[*]If these steps don’t work, try reinstalling the driver: open Device Manager, right-click (or tap and hold) the name of the device, and select
Uninstall. Restart your PC and Windows will attempt to reinstall the driver.

You may also want to visit the computer manufacturer's support website and install the latest graphics driver compatible with Windows 10 and check.

Hope this information is helpful. Please feel free to reply in case you face any other issues with Windows in future.
