The app selector (recent app button) has a display scaling option that allows standard or default mode, for apps that don't work well in 2340x1080p, you can run them in 1920x1080p.
HOWEVER, this is centered from the top left, resulting in awkward displays especially in landscape mode. with 420 width of pixels on the right side and none on the left.
Is there a way to center the output, starting the black bars/image at 210 pixels from both sides respectively?
Ignore the example app, all apps suffer from this.
