Meaning that with lower brightness, it looks fine? If that's the case, then I think that's just the display clipping rgb colors in an unfortunate way, and you just have to keep brightness a bit lower -- You are receiving this mail because: You are watching all bug changes.

When I set the Max SDR Brightness slider to 355 and the Brightness slider to 100%, previously white colors shift toward yellow. This occurs on both HDMI and DisplayPort connections The display is factory-calibrated by the manufacturer, and I'm using certified cables—both a VESA-approved DisplayPort cable and an HDMI-certified cable. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=504412 --- Comment #7 from Anton Valishin --- Now I finally understand what you meant about the brightness control in the KDE UI. However, the display still has a yellow tint when connected via HDMI. It was misleading because it seemed to work correctly on HDMI outputs, but on DisplayPort (DP), it was too dark by default. -- You are receiving this mail because: You are watching all bug changes.

Thank you for your response. While I'm not yet familiar with the KDE codebase and Linux codebase (DRM, drivers), I'm eager to help troubleshoot and debug this issue.

Intel GPU via DisplayPort (DP) in HDR Mode: It does not work properly when connected via DisplayPort in HDR mode. This is not related to the monitor's brightness settings. It works fine over HDMI, but there is a noticeable yellow tint in scenes that should display white. For AMD it seems the same issue as mine "It's like a green-tinted overlay..." -- You are receiving this mail because: You are watching all bug changes.
