HDR Calibration

Hi, everyone, I have another question about IMAGE: bazzite-deck TAG: testing-44.20260910.2; my hardware is: XFX AMD Radeon RX 7900 XT [Discrete] RX-79TMBABF9 and an LG 48 Inch Class OLED B4 Series TV Model OLED48B4PUA. My display settings are 3840 X 2160 (16:9) @ 120Hz, Scale 175%, Adaptive sync set to Never, 10 bits per color over HDMI 2.1. My CPU is an Intel i5-12400, ASUS PRIME H670-PLUS D4, 32GB RAM @ 3200MHz.

When I try to calibrate HDR (it works my question is about calibration), the image above the slider doesn’t change the intensity (except at 0). It goes from 1 to 2,000 without any change. My TV can only do a little over 690 nits. Even if I cancel the procedure, the screen remains extremely bright. I don’t really remember when it started doing this. Just remember that it worked before. I can adjust the brightness by lowering the percentage but then it affects the contrast. Is there a way to reset the display settings to the default state as when one originally installed the OS. It worked before making any changes. I’m willing to leave it as it was. I rather not reinstall the OS again, but if that is my other option I can live with it.

Anyway, congratulations and thanks for this excellent OS.

Hi, everyone, I’m back to let you know that I think my issue was partially my fault. The HDR Calibration interface is still non functional; however, the extreme brightness and lack of contrast was my fault. I overestimated (way over) the capabilities of my TV nits. The actual nits was around 290 in full screen (690 nits was using 10%). It took me a while to find the specs. Tried the new parameters regardless of the look on the interface and now it looks right.

Thanks, again, and keep the good work!
