Samsung OLED 4K 65" S95B TV 2022 - Game Mode not working

[FedeRVNSCRY]

Hello,
just got a new Samsung OLED 4K 65" S95B TV 2022 yesterday and i tried to use the Samsung Game Mode with the steam deck.
Docking the steam deck it seems to work, but after i switch the samsung game mode on, it doens't work anymore. It seems like the dock lose the hdmi connection.
Any suggestions?
Thanks

Hi, I've got the same issue with the s95b. DId you find a way to fix it?
Currently, without game mode I cannot select 1440p@120Hz so I'm stuck to either 4k60 or 1080p120 and the latency is also higher than with game mode.

Valve can you please add support for the Samsung S95B?

Confirming that the official dock, as of latest firmware, still does not work with the Samsung S95B OLED TV (55" model in my case) when Game Mode is enabled.

I went through several troubleshooting steps with support and was advised to post here as nothing worked. The only workaround currently is to use PC mode + “Input Signal Plus”, which will allow 1440p output at 120Hz, but you will lose access to Game Mode’s settings and input latency advantages.

When game mode is engaged, the Deck loses its white light LED, stops charging, and output to the TV is cut. The only resolution is to disable game mode and unplug/replug the dock from HDMI

Just giving a heads up in case anyone was wondering: Firmware 0.13.15.120 that comes with steam OS 3.5 on the preview channel does NOT fix the issue with game mode.
Please Valve fix this! Samsung TVs aren't a niche product :-(

I’m having the same exact issue and currently speaking with Steam Support.
Do we think this is an issue to be resolved by Steam or by Samsung?

Solve by the HDCP stop adding DRM in our damn consumer devices.

Everyone who post HDMI issues also has a new TV. I suspect HDCP handshake issues and the handshake pretty much breaks most dock MST display features.

I just conducted a test and got interesting results. I connected my Steam Deck directly to my TV using a standard HDMI to USB C cable and interestingly, Game Mode works perfectly.

This means that the issue is not with the Steam Deck or the TV - it is with the Dock.

Yea. I was thinking about the Multi-Stream Transport features within the official dock. The official dock is one of the few sub $100 docks with the ability to split usb c signal into two+ displays.

I believe HDCP gives two crap about those use cases. They want their stream uninterrupted. The issue is so bad that Wendell only provides displayport KVM because HDMI DRM is just broken.

Yes, I tried a different dock as well, and that works perfectly fine. I also tried a regular Notebook with Valve's dock and that didn't work either.
People were getting Jsaux docks for this reason, because they also work perfectly fine with Samsung TVs.
It's only Valve's Dock that has these issues

Just a heads up to everyone with a Samsung TV: Dock Firmware 0.13.15.121 that came with Steam OS 3.5.5 fixes the issue with game mode. Finally! Thank you Valve!

Doesn't for me - still get the same issues with the updated dock and my new OLED deck

Same here on an Samsung s95b, need start in low resolution mode every time I want to use the doc to avoid image corruption (red blinking pixels). I can change the resolution back to 4k after connection, and everything is totally fine. Even HDR works.

But I don't want to do tricks every time I connect to the dock...

THRILLED to report this has been fixed!!! I’ve been talking with support for the past two months and they told me they escalated the issue.

I had little hope this would actually be investigated, but today my Dock updated to firmware version 0.13.15.121 and game mode is working perfectly with my Samsung S95B!!!

Thank you Steam 🤩

Does this include the inability for the Steam Deck Dock to register the Steam Deck is turned on and displaying it on the TV (having to do the annoying power cycling with only the HDMI attached and not the charging cable)?

Yea. It sounds like a completely separate bug. You have to either update to preview channel or go to your bios and change usb drd to usb xhci.

USB DRD isn't working so well.
