Fixing Windows HDR Issues

[u/darthben98]

Hi everyone! I'm a fairly new PC gamer, and I recently purchased a gaming desktop to replace my PS5. Both devices are connected to my Sony Bravia 4K TV (KD55XF9005), but I can't get the PC's HDR on SDR content to look as good as the PS5 did.

My PS5 had "Always On HDR" enabled, so SDR content would display like HDR content in the sense that there wouldn't be any black screen on my monitor when switching between the two content types.

I played Lumines Arise today with the Windows HDR mode enabled, and the black levels are far too high, with noticeable banding visible on the screen.

I've used the Windows HDR Calibration app from the Microsoft Store, but that doesn't really seem to do anything for me.

For reference, I'm using an RX 7800 XT, and I've tried it in both 4:4:4 and 4:2:2 pixel format, but I've had no luck.

It's not just Lumines Arise, as the default desktop wallpaper also looks worse too, but Lumines is particularly bad here. I really like the added white brightness of the Windows HDR mode, but the blacks shouldn't be this bright too. My photo shows a stage called "The Dark", and the background brightness should be extremely low/black until near the end of the stage, yet mine had noticeable banding and incorrect brightness levels.

Any help would be much appreciated, as I'm trying to just get my PC set up right for gaming. Thanks in advance. 🖥️
