Every PC I’ve ever used automatically detects and adjusts resolution to the display you connect to it. Even Nintendo Switch will detect when it’s docked and automatically adjust the display resolution. But on Steam Deck you literally have to adjust the display resolution for every game, every time you switch displays.
Since getting the SD I have shoved my PC into another room to displace the heat (until I get a mini-split) and I just stream from it to the Deck, whether docked at my desk or on the couch or on the big screen. But this really complicates that process unnecessarily.
This has also not been fixed in Nobara or Chimera.
What’s the limitation there?
Some games will also save the resolution when it generates the default graphical settings and then save that and reuse that. So if you then plug in an external display, the game doesn’t even look for that. It loads the last settings which would be 720p.
Also the Deck runs games under gamescope which has its own upscaling. So it probably sets the virtual screen to be the deck’s native resolution regardless of what’s plugged in, and hope FSR is good enough and minimize the need to also have to switch other graphical settings for the game to run properly at higher resolution.
Not sure why it would do that for streamed games though. How’s the game on the PC even aware of the resolution of the Deck?
