Pi4 + official Display calibration problem

Fri Nov 22, 2019 1:58 pm

Hi guys,

I need to calibrate the touch of the pi on a official 7' display, in vertical position. I use the screen utility to rotate, and I see DSI-1 & HDMI-1.
then is use this string :

Code: Select all

#!/bin/bash
DISPLAY=:0.0 xinput --set-prop 'FT5406 memory based' 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1
With the Pi3 (display_rotate=3 ) works, and the touch is perfect.

with pi4, it works only on half screen because on the top I see the second desktop (hdmi-1) so I can't calibrate.
is there a way for solve this problem?

thanks

Drag the HDMI screen off the DSI screen using the screen config utility, does that help?

Any other have this issue with the new pi4 ?

I need to solve this problem, because here in my country is a bit hard found the pi3, so now I need to use the pi4 in my factory.
