Windows 10: Window borders not visible on 4K displays

Like this question, which never got a useful answer https://answers.microsoft.com/en-us/windows/forum/all/increase-border-thickness/66ebc86c-d06c-4b02-ab17-5818e6740369Applications that have a black or dark client area become indistinguishable from any window it is in front or behind, because the borders are not easy to then grab and resize or easy to click on to foreground the intended window. This is a larger problem on laptops where the graphics drivers are poor and users have disabled most of the shadow or other effects. The M$ representatives seem to believe that removing settings has mad

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.

 

Windows wont display 4k and HDR simultaneously.

I recently got a 4k HDR tv (Samsung UE43NU7100). I connect my PC with a normal HD monitor and the 4k HDR tv. When turning on HDR on my tv the resolution of the 4k tv (3840x2160) gets set back to normal HD (1920x1080) in windows settings. Windows is completely
updated, my AMD Radeon R9 390 8gb graphics card is up to date and supports and displays in 4k when HDR is off. My Xbox one X displays both 4k and HDR perfectly simultaneously. I use a high speed HDMI 2.0 cable. I have no idea why my pc does this and cant find
anything about windows not being able to do 4k and HDR at the same time. It also doesn't work if I only connect the tv instead of the monitor and tv. Any suggestion?
