Talk:HDR monitor support

Title: monitor or display?

I'm thinking HDR display support might be a better title for this page as its not exclusive to monitors. Perhaps a mod could move everything and clean up the mess I made earlier with the incorrect case page. Dungeonseeker (talk) 15:40, 11 January 2023 (UTC)

Section 2.2 Configuring through SteamOS UI Does not seem different from 2.1

@Dungeonseeker I think the two sections could be merged. I added -steamdeck to the command to fix the black screen issues. It was not needed at initial time of testing. HDR settings are available in the Steam UI when configured as in 2.1. It mostly sets settings for gamescope.

CLIENTCMD could be removed as it matches upstream now, but I left it in to show how to set it.

Step 10 in 2.2 is a good note as it is needed. I also needed to tweak ui resolution and scale otherwise it did not take up my monitor's resolution.

Unfortunately, there no way to set connector without overriding the entire GAMESCOPECMD at this time.

Thoughts on merging the two?

I consolidated the sections. Hopefully it is ok.

I removed steps that are no longer needed such as Soldier Runtime beta and Steam Client Beta. Removed extra environment variables that are no longer needed.

Proton 8.0 includes the required bits, so mention that over Experimental.

Note that the config file is optional, but may be needed if it is not getting the correct resolution or connector. Maybe this could use some improved wording.

Updated to reflect the new gamescope-session-bin and gamescope-session-steam-bin packages.

Tested everything again to confirm HDR is working. Murrant (talk) 03:45, 17 October 2023 (UTC)

I have no objections at all as long as its accurate, unfortunately I can no longer test HDR related stuff at my end, I upgraded my monitor a few months back and gained an extra 3" + 144hz but lost HDR. Dungeonseeker (talk) 07:41, 17 October 2023 (UTC)

HDR more feasible soon?

So I've been reading https://libreddit.bus-hit.me/r/linux_gaming/comments/18xgt7w/baldurs_gate_3_hdr_on_linux/kg43a2z/?context=3 and https://zamundaaa.github.io/wayland/2023/12/18/update-on-hdr-and-colormanagement-in-plasma.html and it seems the kernel patches mentioned in this article are no longer necessary? Also, it would appear like Plasma 6 which just came out might be workable with HDR? Perhaps someone could test this and overhaul the article a bit. Svenstaro (talk) 02:51, 1 March 2024 (UTC)

I agree this page should be revised. At least the situation with plasma 6 should be addressed. 4color (talk) 05:51, 2 March 2024 (UTC)

Yes, the page needs many updates. There are now reports of working HDR using Plasma 6 and NVIDIA, presumably with an unpatched kernel https://forums.developer.nvidia.com/t/plasma-6-0-hdr-success-report/284564.

I'll add that NVIDIA has HDR starting with 550.54.14. Crimist (talk) 22:56, 2 March 2024 (UTC)

Are you sure that you specifically need version 550.54.14? The user reported that it worked on 550.54.14, they didn't say it didn't work on earlier versions. I think more testing is needed. 4color (talk) 14:18, 3 March 2024 (UTC)

Yes, "Added support for HDR signaling" in the 550.54.14 release notes: https://www.nvidia.com/download/driverResults.aspx/218153/. I'll add a citation. Crimist (talk) 00:05, 5 March 2024 (UTC)

I confirm HDR works with Plasma 6 + Nvidia + unpatched (regular arch) kernel. Zen kernel works too. 4color (talk) 23:58, 7 March 2024 (UTC)

Thanks, I've added linux as a supported kernel. I believe we can now remove the note about linux-neptune-65^AUR as the appropriate patches must have been merged? If there is no opposition I'll do so.

Regarding Nested Plasma 6 I think the article will need some restructuring to provide the two different options - nested Plasma 6 + gamescope and big picture gamescope. Crimist (talk) 02:38, 8 March 2024 (UTC)

Actually I have to clarify, I haven't tested hdr gaming. I just mean it works in desktop mode. 4color (talk) 02:48, 8 March 2024 (UTC)

Ah okay, I should have some time to verify that for myself this weekend. Crimist (talk) 02:50, 8 March 2024 (UTC)

I think structuring it the way you suggested is a good idea. Svenstaro (talk) 03:23, 8 March 2024 (UTC)

I don't currently drive an HDR screen myself so it would be great if you guys could look into updating the article if you have some time. Svenstaro (talk) 00:24, 4 March 2024 (UTC)

I've updated the article as I described adding Plasma 6 and generally doing some refactoring. Feel free to review and fix any formatting or clarity issues.

I believe with these changes the page is relatively up to date until Wayland merges HDR support and wlroots & compositors begin to implement it. Crimist (talk) 03:27, 19 March 2024 (UTC)

The structure makes a lot more sense, thanks! Svenstaro (talk) 04:32, 19 March 2024 (UTC)
