I saw this demo for the first time with an HDR display and I’ve still yet to come across content that pops like this. I wish everything looked this good.
If you ever get the opportunity, try out HDR ITM tone mapping (essentially a HDR upconversion thing you can do with Gamescope on Linux) playing Persona 3 Reload on a QD OLED monitor (for that extra brightness) in a dark room. Even though it's not even a native HDR game, with ITM it looks so good, especially because it's a game with a lot of dark graphics mixed in with super bright. The text pops, and combat is next-level.
I don’t know if I want my text to be that bright TBH.
I have a 1000 nits monitor and IMO it looks best with things like stars in a night sky or lights in a dark cave.
When it gets too much of the screen bright at once it hurts my eyes. Sometimes that happens when playing Destiny 2, which generally has a pretty good HDR implementation, but when too many explosions happen at once it gets overwhelming.
Really good 4K+ scans of film made with HDR in mind can look even better than that. That video demo has some amateurish lighting here and there. Hollywood level professional lighting and production looks extraordinary if tone mapping was properly done during digital scan. Right now there's a lot of bad quality HDR and sketchy OLED panels around, though.
I think that's mostly because it's (a) 60 fps, and (b) they use a lot of pure black to really bring out the contrast on OLED screens.
Atmos is friggin' awesome though, same with DTS-X.
1000 nits is actually not that much, a full moon is 2500 nits. A lot of movies are mastered at 4000 or 10000 nits
In a small room where it's the only light source, it's still a crazy amount of light. My eyes genuinely had to get used to the brightness for a couple minutes after I set it up for the first time, and the walls sometimes looked like the ceiling light was on.
I couldn't get Nvida to work reliably with HDR. It would run, but I'd always get a crash after a bit.
Im on Bazzite with a 3080ti GE Proton
HDR on a 300 nits monitor is like trying to watch a movie with your eyes mostly closed lol
I dunno why 300 nits monitors advertise HDR, except I do, it's an extra "selling" feature despite being useless at that brightness.
VESA honestly should ban manufacturers from having anything below HDR 500 certified as HDR, as the specification is so watered down with HDR 400 and below (sRGB? Really? Why not WCG like all the other standards 500 and up?). HDR on a 300 nit display is terrible, and manufacturers should be embarrassed to sell those as HDR.
Gnome 48 + Wayland and HDR works great... At least for me
For me it works great only when watching a HDR video on mpv and everything else looks washed out and pale. Including the entirety of Firefox and its content.
Never had hdr, don't know how to miss it. Must be like dolby atmos or 4k where its a scam from hardware manufacturers to sell you shit that does nothing but make you buy more.
I just can't get HDR working and it's annoying.
What sort of system are you on, and what have you been trying? The best setup is with an AMD GPU and a more up to date distro (Fedora, Arch, so on). I can give some help if you need.
why the fuck is brightness slider not working in fedora after enabling HDR?
Working fine for me on Bazzite (Silverblue}
Here's a great blog post by one of the people working on it in KDE.
TLDR: typical brightness settings don't include the viewing environment and this is very much a work in progress point in KDE.
