HDR Output and Remote Play-Feature Request

[Relámpago]

Hello, this has been a significant gripe with Steam Remote Play and is one reason I used the Nvidia Shield in the past.

That is the complete lack of HDR Support while streaming. As far as I can tell, the dock and steam deck have the hardware to display HDR on a TV that supports it. My gaming Monitor and TV are all 4k HDR, but even after all these years, steam still does not support HDR is quite frustrating.

Since the last generation of consoles, HDR has become more and more standard in games; these days, every game supports it. We are talking about a much broader colour, the gamut. It kills the eyes not to be able to leverage HDR.

Please, please, Steam!

Also now that we have a docked Steam Deck we need a Steam Controller 2 to make the most use of it!

Such silence to such great request!

Hopefully Valve listens you can stream the ps5 with HDR but why not your PC? :(

I got a little bit interested and see whether or not the deck has HDR support to encode and decode.

I guess they will need to support h265 for HDR streaming. They can decode VP9 hdr stream if they ever decide to add support for VP9.

We can already do it for PS5 streaming to Deck with full HDR support. Moonlight can do it on my nvidia shield as well but it doesnt seem to allow me to enable it on the deck possibly because its a linux client and linux normally does not support HDR untill valve helped move that along.

Linux HDR isn't the largest issue thou. Valve controls gamescope and can bypass all Linux political standardization problems.

I question the decode and encode performance on AMD chips. Hardware acceleration are fixed function devices. You need a decent asic that isn't buggy to make it work. Those dedicated hardware is pretty narrow on what it accepts.

No but the moonlight devs would need to add support for it. Moonlight can stream HDR to android devices and windows just not on the steam deck with their Linux Client.

The fact we can do it already for some devices means its possible.

Looks like Moonlight already has it in development:

We just need it steam link natively.

Wanted to second this feature! Would love to be able to stream from my HDR desktop to my HDR steamdeck OLED! :D

Now that steam deck support HDR this is a must feature.
