Connect USB mouse and keyboard. You should be able to change it in factory settings

UPDATE: 26/06/2017 Users of 800x480 Users must also apply file[dmcu.ext], a text file containing:
For PX3 --> screen:3
For PX5 --> screen:1

extract and copy dmcu.ext on sd card. In recovery menu use update mcu from sd card

I have the same problem with my radio PX5 for my Toyota Yaris with*Android*8.0*and when installing Rom and MCU updates have changed the screen resolution to 1024x600, when the correct one is 800x480, I have reinstalled several times even doing wipe data and wipe cache . My MCU version is MTCE_MX_3.0 and the current Rom is MX4_PX5_8.0 (20181122). Let's see if someone can help me.
