@barrymossel said in Resolution doesn't change:

. Still weird that setting resolution through the configuration editor doesn't work.

The configuration editor is for RetroArch configurations and I think RA doesn't change the resolution of screen itself. What you actually want is the runcommand resolution switch - which works with tvservice. Another option is to use the onstart/onend scripts to switch resolution, instead of manually configuring per-emulator settings in the Runcommand.
