You’ve missed this part of the faq: Screen Aspect Ratio/Resolution/touch calibration
To get the right video size/calibration, ALWAYS turn the screen on BEFORE turning on the controller. The controller reads the screen (if it’s on) to know what size it should adjust to before displaying video. If the screen is turned on after the controller, you may have black bars on top and bottom of the screen and the ‘touch’ input will be off by a few mms.
