I’ve had the same issues. I thought it was because I was using a cheap dock or dongle.

On one of my TVs that support 4K 120 Hz in Game mode, it only allows 1080p 120 Hz in game mode or 1440p 60 Hz in regular mode. Also, I can toggle HDR on but it doesn’t toggle HDR on the TV itself.

On my other TV it does 4K 60 just fine but that TV doesn’t support HDR.

I really like the endless mode of Inscryption once you finish the story for a turn based game.

I’ve been able to play Bloodborne on my Steam Deck… With Remote play and Chiaki… and it’s still running at 30fps… Man, I wish we could get a PS5 patch, or better yet, a PC port.
