Bazzite Gamemode HDR on a LG C2 oled
Toggling the hdr option in steam when in the gamescope session does nothing on my LG C2 (just filkers and nothing happens) HDR works perfectly fine in a plasma session, its only in the gamescope session that it has issues.

should mention the same tv works fine on steamos game mode running on a deck. haven't tried bazzite on the deck with the tv...
huh intrestingly hdr works if I connect my tv directly into my 6700xt HDMI port instead of going trhough a DP to HDMI adapter.
it works on plasma though with the DP to HDMI adapter.
I am using the adapter to workaround the lack of HDMI 2.1 support on linux with AMD
Just give up on the adapters. Been going through this for 2 years the things break one update to be fixed in another, then just to break again. I'm personally just waiting for rx8000 to hopefully get HDMI 2.1 working.
Use HDMI at 2.0 levels. Lock games to 60hz and just move on... While shaking your fist at the HDMI forum for being giant tools.
its unlikely, HDMI 2.1 is being gatekeeped by the HDMI forum, they're not budging last i heard
yeah guess ill just plug in directly when playing HDR games.
its just so strange that hdr works with the adpater on plasma but not in gamemode
like right now I can set my plasma settings to 4k 120 hdr no problem and it will. work but on the steam game mode I get nothing when enabling hdr
not even no signal it just straight up does nothing the image does not change
i want to give this a try: https://www.store.level1techs.com/products/p/5megt2xqmlryafj8bd79487o64sude

This feeder provides 30 sets of memory banks (1 Preset + 29 Custom) for EDID setting, including EDID Reading / EDID Copy / EDID Emulating procedures. The EDID Export function allows the EDIDs stored in the memory banks to be easily transferred to the computer through a mini USB cable for advanced
From what I understand. Everyone is implementing HDR slightly differently. We are waiting on Waylon's support before everybody switches over to that. So until then I would expect different bugs for different DE.
I have probably spent over $200 on various adapters and they all have their own special unique issues.
actually im not sure if this can be used as an adapter, i will have to check, maybe im misunderstanding what this device is for
Just using HDMI 2.0 over a 2.1 system, everything works except for VRR and 120 Hertz. Does not matter if I am connected through my Denon on AVR or directly connected to the TV. Once you max out the graphics in most games, you're hovering around 60 Hz anyways.
yeah thats the main thing i am missing out on with hdmi 2.0 VRR. honsently VRR is more important to me than HDR
i just wish tv's had displayport instead of hdmi and this woulnd't even be an issue
I mean, I even have this issue on my Samsung Odyssey G9 OLED. I can't control the display brightness and a couple other features because I don't have HDMI 2.1 support. I really hope AMD for the RX8000 series implements HDMI 2.1 the way Intel does.
don't they just have a built in adapter?
Or you know, Nvidia's driver nonsense becomes less of an issue in the future. And I can just switch to that.
Yeah Intel uses a built-in HDMI 2.1 adapter to display port.. That way they can have HDMI 2.1 driver closed source while still having a open source display driver.
i mean all amd has to do to match that now on earliar cards is sell there own adapter either made in house or just a reband of one of the ones already on the market they just make sure it works and all features are exposed correctly and done
AMD is apparently still in talks with the HDMI form To find a solution. Obviously due to the fact that the users that need this are pretty much the 1% of the 1% AMD is going to want to solve this in software not hardware because it's not financially reasonable. Even designing an adapter in-house and selling it like how many people are really going to be buying that.
not if they sell it for like 60$ i think that would easily outway the costs in manufactoringthe adapter . i would gladly pay 60$ if it meant having full support for hdmi 2.1 features
even if linux usesers are 1% of there coustomers (i think it may be closer to 2% with the steam deck) thats still alot of money to be made for a relativly cheap piece of hardware ofc best case senerio (except the HDMI fourm) for everyone is if they solve it in software but I doubt it
Solution
Recent steam update fixed it 🎉
