I've spent the past hour attempting to figure this out, to no avail...
I've hooked up my Raspberry Pi 4 to the 7" Touchscreen Display, and unfortunately I'm running into an issue with the resolution being larger than the display itself.
Output of tvservice -s:
state 0x400000 [LCD], 800x480 @ 60.00Hz, progressive
I have overscan disabled, and I made sure that /boot/config.txt doesn't have anything with overscan enabled in there.
The right side of my screen is cut off, I can't see the clock, and I can move the mouse off the physical screen. The touch is also offset, so if I touch anywhere on the screen, the mouse is about a centimeter to the right...
