Hdr400HDR isn't functioning properly within the games.
You've been using your monitor for some time now. Even with HDR 400 support, you still want the flexibility to use it when you're ready. To keep things consistent, you can enable HDR in Windows HDR mode, but when playing games the system reports it lacks HDR compatibility. There seems to be a connection between using two DP ports and boosting the monitor's refresh rate to 144Hz—could that be the same for HDR? Your Acer ConceptD CP3271KP model might require two DP inputs to achieve HDR performance.
It’s unclear what to do anymore since it functioned when I first received it. Now it only works on Windows and needs a specific setup to use in games.
In the image, the HDR button isn't activated. It seems HDR needs to be turned on on the monitor for it to function in games, otherwise it won't work.
It varies based on how the game handles HDR. Some depend on the Windows setting, meaning if it isn't turned on for Windows, you can't activate it within the game. I'm aware of Horizon Zero Dawn using this method. Switch HDR on in the Windows display options and check the available settings inside the game.
It functioned in cyberpunk but not in other titles like "Far Cry New Dawn," especially when HDR is turned on in Windows.
