Reduced color contrast in video with A770 hardware acceleration in Chrome and Edge.

[FeOAr]

**Chrome Version:** 127.0.6533.120
**GPU:** A770 Driver Version 5762
**Platform:** Windows 11

I discovered by accident that when I scroll the playback page on any video website, the video being played momentarily returns to normal contrast. Manually adjusting the color settings, even by changing the contrast from 100 to 100, also restores the video contrast (it seems like the configuration gets overridden). However, when I reset the color settings or refresh the page, the contrast drops again, making the video look gray. After troubleshooting, I found that this issue occurs when hardware acceleration is enabled and the A770 GPU is used. This problem does not occur when I use the integrated UHD 770 GPU or when I disable hardware acceleration.

It sounds like you're encountering a problem where hardware acceleration with your A770 GPU affects video playback contrast in Chrome. Here are a few steps you might try to resolve this issue:

Update GPU Drivers:
Ensure you have the latest drivers for your A770 GPU. Sometimes, newer drivers can fix compatibility issues with hardware acceleration. You can check for updates on Intel’s website or through the Intel Driver & Support Assistant.

Adjust Chrome Hardware Acceleration Settings:

Open Chrome and go to chrome://settings/.
Scroll down and click on "Advanced" to expand more options.
Under the "System" section, toggle off "Use hardware acceleration when available."
Restart Chrome to see if the issue persists.
Change Video Playback Settings:
Some video playback settings or extensions might interfere with contrast. Try disabling any video-related extensions or settings and see if the issue is resolved.

Check GPU Settings:

Open the Intel Graphics Command Center or the equivalent software for your A770 GPU.
Look for settings related to video and hardware acceleration and try adjusting or disabling specific features to see if they impact the issue.
Test in Incognito Mode:
Open an Incognito window in Chrome (Ctrl+Shift+N) and test video playback there. If the issue doesn’t occur in Incognito mode, it could be related to an extension or browser cache issue.

Reinstall Chrome:
Sometimes, a fresh install of Chrome can resolve persistent issues. Uninstall Chrome, then download and install the latest version from the official website.

Check for Conflicting Software:
Other software or system settings might conflict with hardware acceleration. Ensure your system is free from conflicting programs that might affect GPU performance.

Report the Issue:
If none of the above steps resolve the problem, consider reporting the issue to Chrome’s support team or Intel’s support. They may provide additional insights or updates that address the issue.

If the problem continues, you might need to use integrated graphics or disable hardware acceleration for video playback until a fix is released.

I tried using Incognito mode, but it made no difference; the contrast issue still persists when using A770 hardware acceleration. I'm certain that this problem only occurs when using the A770 for video stream decoding in Chrome. When I play videos locally with PotPlayer, there is no contrast issue. I will report this problem to Chrome.

Hello FeOAr,

Thank you for posting in the community!

To better assist you and determine the most appropriate resolution, could you please provide the needed details listed below:

May I know what website are you accessing that you are encountering this issue with?

Is this you're first the encountering the issue?

Are there changes on the system before you encounter this issue?

May I know if the color contrast working fine before?

Once we have this information, we will be able to proceed with the next course of action and work towards resolving the issue you are facing.

I did some testing when I discovered this issue, using both Chrome and Edge browsers, and the behavior was the same in both. I tested this on bilibili.com and YouTube, and found that as long as hardware acceleration was enabled for playing any video, the contrast was abnormal. This seems to be unrelated to the bitrate, format, etc. Today, I tested it on Firefox and found that the issue was gone. With hardware acceleration enabled on Firefox, the video's contrast appears normal. I will take some time later to submit this issue to Chrome.

Hi FeOAr,

You can try performing driver update to the latest version: 32.0.101.5989.

Thank you for your response. I tried the latest 5989 driver, but the situation hasn’t changed. Then, I tried reinstalling Chrome, but the issue remains the same. The current conclusion is still that Chrome's hardware acceleration doesn't support the A770, but Firefox does.

Hi Feoar,

Thank you for considering our suggestions so far.

Since it is not happening in Firefox, we thought of some workarounds that you can do. I will arrange from the least aggressive to the most in terms of disabling hardware acceleration. Please see the recommendations below:

1. Open chrome://flags and search for “Choose ANGLE graphics backend” change it to “Open GL”

2. If that does not work, you can disable only hardware acceleration for video decoding only. Search for Hardware-accelerated video decode and change it “Disabled”

Kindly let us know if the above workarounds mitigate the issue.

Thank you very much for your reply. I tried to make some adjustments, and after testing, I found that both OpenGL and D3D9 can display colors correctly. However, the contrast issue occurs only with D3D11. Also, it's not that FireFox has no issues—there is a slight contrast anomaly that I hadn't noticed before.

In short, after switching to D3D9, all problems seem to be resolved. The smoothness is unaffected, and the video colors are now normal. Thank you.
