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?
For sure but even windows has the registry and macos its terminal, its not uncommon for non-common usage cases to not have a nice pretty setting on the home screen.
I'd say it'd make a lot more people hate the deck if every time they tried to use it on a tv it lagged to ass cause it defaults to the 4k of the television when it struggles at 720 normally.
100% support where steams efforts are going, and I don't think it should be on menial issues like this
