Hi
My Hyperpixel 4.0 Rectangle is working well in its default portrait orientation.
When I change rotation to “Left” as documented, via the Screen Configuration in the GUI, the touch screen is no longer accurate - like others have said, by 50 pixels or so.
I’m running the latest Bookworm, fully up to date, and my config.txt is below.
I saw a bunch of older similar posts, but they seem to be specific to the Bullseye release. Couldn’t find anything specific to the built-in driver setup.
