Windows 10: weird blue block like things on my 2nd 4k display

Hi ive been having an issue with my 2nd display 4k recently and ive noticed blue blocks, what is it most likely to be? i dont think its a display driver issue or i would have the same effect on my main 1080 240hz monitor? im certain its not the hdmi cable and ive tried to configure display settings in windows with no luck any ideas?

i've also noticed it only happens when immiting lots nits of brightness, eg when i use lightshot to capture a screenshot it darkens both my monitors and the blue blocks go away. i have no idea the issue is, if i take a screenshot of the blocks then view it on my primary display they're gone so its %100 a display issue.


so to check if it was a colour issue i took a screenshot of blue blocked area on my display, then saved it and englarged it and put it back on my 2nd display to see if that would make the blue blocks larger, and it did. however it isnt a specific colour it happens to, its almost random.


i use f.lux which reduces blue light late at nights however even when thats on it doesnt effect the blue blocks, they are still in the exact same place even though the level of blue light is reduced, so if its not a specific colour palette then what could it be? maybe im overthinking this a bit but any infomation could be usefull i guess.


any help would be much appreciated, thanks.

Does Miracast support 4K?

Hello,

We suggest that you check with the manufacturer of the 4k display device that you are using if it is certified to work with Miracast. If your display device is certified to work with Miracast, then check if your PC device supports Miracast. You may do so
by following the steps below:

• Click Start, then go to Settings >
  Projecting to this PC.
• Check if your device supports Miracast.

Regards.

 

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.

 

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?
