Windows 10: Screenshot functionality seems to fail when one of two screens is in HDR mode

OS Name Microsoft Windows 10 Pro
Version 10.0.17134 Build 17134

Geforce 1050 Ti driver 418.91

I have one screen in 1920x1080@144Hz (ASUS VG248QE) and a second screen in 3840x2160@60Hz (BenQ PD2700U, 4K).

HDR is enabled on the 4K screen.


Problem statement:

When using the screenshot function that I've demonstrated with Snip, the image colours on the HDR screen are badly affected.


Evidence:

The demonstration image shows a reference PNG image (http://r0k.us/graphics/kodak/kodim08.html) on Internet Explorer being shown on both screens. The HDR screen holds the right side of the image.

The same result is shown with other screenshot applications (e.g. Greenshot).

The issue is not present when using just the HDR screen.


Question:

It appears that the screenshot functionality cannot handle the difference between HDR and non-HDR displays and treats the HDR pixels as non-HDR, losing colour information. I'd guess this is a bug and suggest that the screenshot methods should default to the HDR image and translate non-HDR pixels to HDR versions.

Windows 10 HDR problems in full screen.

Hello moderator

1. Its all the games I own that don't support HDR10. Basically when I full screen on a non-HDR game, the screen goes black for a few seconds and HDR gets disabled and all the colors looked washed out (Like its in SDR)

I took 2 screenshots, One is in window mode, the other is in full screen

Windowed mode (HDR on) : Imgur

Full screen mode (HDR off) : Imgur

2. Yes SDR looks washed out. I want to play my games in full screen and in HDR. Playing in windowed mode is a nightmare

3. I know because the monitor goes black for a few seconds and all the colors look washed out (As shown in the screenshots)

Sadly the fixes did not work

I updated the GPU drivers via GeForce Experience app.

My Monitor does support 4k HDR10

I tried lower the resolution and the refresh rate but that did not work.

Here is a video of my problem

YouTube Link :

Time Stamps :

0:00 HDR mode is on everything looks fine (In the video, when it looks high contrast, that means HDR is on)

0:35 I full screen the game. If you notice the high contrast is no longer there, the colors are washed out

0:46 I disable full screen and HDR mode is back on

*HDR looks high contrast, Ignore that, that's just the video itself.

Im also using windows 10 64bit 1809

 

Problem with HDR in full screen mode

In full screen games HDR mode gets disabled and all the colors are washed out. But in Windows Mode HDR mode
gets enabled and the SDR game runs in HDR

Guide 3: Reduce Frame Rate.

3: To change Frame Rate go to Display adapter properties and reduce resolution, then switch to Adapter tab and choose List All Modes.

4: In List All Modes, choose the setting that includes 1920 by 1080, 60 Hertz, then click on OK

5: Restart your PC

Write me back if it works or not.
