HDR Confusion

Hey fellas, could you help me understand a bit more about HDR?

  • I understand that it's an absolute brightness standard, not like the relative levels in SDR
  • But why does it end up washing out colors unless I amplify them in kwin? Is just the brightness absolute in nits, but not the color?
  • Why does my screen block the brightness control in HDR mode but not contrast? And why does the contrast increase the brightness of highlights, instead of just split midtones towards brighter and darker shades?
  • Why is truehdr400 supposed to be better in dark rooms than peak1000 mode?
  • Why is my average emission capped at 270nits, that seems ridiculously low even for normal SDR screens as comparison.

Cheers 😊

Edit: It's a QD OLED

Before your change to Linux
  • I think it was win 8. I've dual booted excessively until dxvk basically made such a dent in the gaming exclusivity that I just stayed and enthusiastically followed it grow into perfection

  • Has anyone got KDE Plasma 6 - Wayland running on Arch using an NVIDIA GPU?
  • I'm on endeavour, though i also really liked manjaro. in terms of nvidia+wayland I'd say it's very flaky.

    • vrr works SOMETIMES. i have to log out and in 2-3 times into my account until the option shows in the settings, and also functions as proven using vrrtest-git
    • standby corrupts cuda and you'll need to modprobe or reboot to fix it.
    • hdr shows up but looks really grey and colorless for me, but it might be my monitor's edid being faulty. kde's sdr color vibrance option didn't help.
    • external screens are dropping frames, down to 30fps, where it was fine on windows with 60.

    Keep in mind this is a 3060 laptop gpu. that means it could well be due to mux switching or whatever else. nonetheless i think nvidia seems more reliable on xorg as of this point in time, and I'm not going to buy another nvidia gpu.

    this might not apply to desktop cpus at all but i thought I'd share these in case someone else has the issues as well and knows a fix, or knows for sure it's better on desktop, so i can reconsider my stance for a tower build đŸ€”

  • Why do you still hate Windows?
  • there are too many little details to point out but windows just controls your experience too much. for example on a widescreen i don't want to be forced to have the taskbar on the long edge. and up to including w10 the taskbar placement could be chosen. in windows 11 it's forbidden... i installed a software to hack this but of course then explorer.exe breaks every 10 minutes.

    the spirit of computer technology is a universal tool. Microsoft strongarms the user to be a tool. so no thanks

  • I am inevitable.
  • bought hades 2 straight up without reviews and knowing it's gonna be wonky early access, just because the dev has a history of honest and inspired banger games. 😎👍

    keep in mind that most profiteering rats pile onto the biggest cash cow games. indie scene is better than ever these days
