EmulationStation not booting with forced video mode

windfisch

I just got my Pi400. When I force the resolution to be CEA-31 (1080p50) I get a black screen when ES starts. Anyone experiencing similar issues?

@windfisch Does your display support this resolution ?
Attach your config.txt and the output of tvservice -s.

EDIT:
When plugging into the other HDMI port and issuing tvservice -e "CEA 31 HDMI" manually before booting Emulationstation, it works for some reason...

tvservice is not working on a Pi4 as on previous models, it's not the correct command to change resolution. Use the runcommand video mode selection to do so, before starting a game.

windfisch

The runcommand method does not work for me, this produces the aforementioned strange results. Since I only intend to use this setup with 1080p50, I put the tvservice command that sets 1080p50 in my autostart.sh before starting ES.

mitu

Then set the resolution via raspi-config or directly into config.txt, this will set the resolution globally, without the need to run tvservice. See https://www.raspberrypi.org/documentation/configuration/config-txt/video.md.
