I replaced the 8" touch screen with one shown in FAQ as user confirmed. WIMAXIT USB C Portable Touch Monitor 15.6 inch Full HD 60Hz HDMI Type-C External Gaming Display .
Worked good at first, but now calibration is off.
Is there anyway to calibrate the screen so your touch is on the button? Wifi works so I can use my laptop.
Replying to my own comment. WIMAXIT Touch screen seems to be working now when I turn the power on the screen before I power up the 1F. Just got everything working this week.
