1080p on RetroPie and raspberry pi 5?

andyPandy

So I've been going a bit crazy trying to get Retropie to run in 1080p with no success so far. I've read the official docs regarding forcing set resolution through changing the config.txt and have tried a lot of different commands but nothing works.
I had success changing to 1920x1080 in the retroarch settings inside emulation station but when I'm running games it's stuck on 3840x2160.
I've also tried changing resolution through raspi-conf but there is no resolution setting in the display settings (I've read something about it being removed in latest version).

Has anyone had the same issue?

You can force a boot resolution using the video parameter for the kernel boot, like any other KMS platform - see https://wiki.archlinux.org/title/Kernel_mode_setting#Forcing_modes. This means adding to the in the cmdline.txt file from /boot/firmware (NOT config.txt) the video=HDMI-A-1:1920x10280@60 parameter at the end of the line .

You can also leave the kernel parameters untounched and just start emulation with emulationstation --resolution 1920 1080 and it would start in 1080p.

For games to start in the desired resolution, use the runcommand launch menu and choose the resolution for the system.

@mitu Thanks! I tried it but it still doesn't change anything. I can change the resolution to 1080p inside a game and it work but then when I restart the game it's back to 4k resolution.

@andyPandy Okay I changed the resolution in the Runcommand menu. Now it works. Do I have to manually do this for every emulator?

Yes, the configuration needs to be done for each emulator, the first time you start a game with it.
