HDR and SDR screen combo causing problems

Reported by biglep2...@gmail.com, Jun 22 2018

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.87 Safari/537.36

Steps to reproduce the problem:
1. Connect both an SDR screen (built in laptop) and HDR TV
2. Use chrome beta to circumvent the problems the stable release is having with HDR
3. 

What is the expected behavior?
The Colors on the SDR screen should look the same as previous, the colors on the HDR screen should no longer be greyed out like with the stable release

What went wrong?
The HDR screen now displays colors correctly, but the SCR screen is VERY oversaturated. In the picture below the screen on the right is chrome 67, on the left is chrome 68 beta. AS you can see the text on the left screen is very saturated out. (I am also running a dark theme but same thing happens with it disabled)

I believe what is happening is chrome is trying to display the HDR color space on the SDR screen, causing wash out.

Did this work before? No 

Chrome version: 68.0.3443.33  Channel: beta
OS Version: 10.0
Flash Version:

Thanks for filing the issue!

As we do not have HDR TV and SDR screen(built in laptop) combination in order to test and confirm the issue, hence adding label "TE-Hardware-Dependency" and requesting someone from respective team to have a look into this and help in further triaging it.
Note: Tentatively adding component "UI>HighDPI" please change if this isn't apt.

Psyrex reports 6/27 here:

I have installed the beta. Even in that, the with the SDR brightness at it's maximum, the brightness is still half way between current Chrome's and what it should be. So, it's still grey. 

-Windows ver. 1803 ( Build 17134.112)
-Chrome ver. 67.0.3396.99 and 68.0.3440.33
-PC Hardware. Nvidia GTX 1060 - Intel Core i7-7700HQ. Samsung C27HG70 HDR display
-Both HDR and SDR displays running at once. 144hz HDR display, 120hz SDR display.

Chrome when it launches both in the beta and the regular release seem to start off fully bright, at least they flash for a moment, and then both versions go grey. The official release being darker than the beta, but the beta still being darker than it should. 


Psyrecx: later reports - ...you cannot screenshot this, as for some reason, it does not show chrome as greyed out ... in the screen capture.

Same forum URL as above.

Is this related to the CTM bug?
Cc: mcasas@chromium.org dcasta...@chromium.org
No, this is on Windows so it's unrelated to the CTM issue.

+dcastagna and +mcasas in case they have any ideas what this is.
So I tried hooking up an SDR screen to my windows desktop.
Using chrome canary, I was not able to reproduce the bug.
However, as I moved the window from the HDR screen to the SDR screen, the colors were way off for a short time until chrome figured out that it was a on a different screen and adjusted accordingly.

Not sure if the problem has already been fixed, or if there is something different about your system compared to mine.

Status: Closed (was: Unconfirmed)
Closing as wontfix since I cannot reproduce this bug.
If it is still an issue, please let me know.
