I am trying to get my Pimoroni HyperPixel 3.5" display working with Raspberry Pi Zero W. The Raspberry Pi works with a standard HDMI monitor. I set up my RPi with NOOBS and then ran the script from https://get.pimoroni.com/hyperpixel4.
When I connect the LCD, the image is corrupted.
I tried changing the rotation from LCD_ROTATE=3 to LCD_ROTATE=0 and that changed the rotation as expected but didn’t improve the reversed/ color inverted image.
The background picture is fjord so all the detail in the image is there, just not in the correct order. You can see the menu bar at the top of the screen; reversed and in some weird color scheme. Also, the image is small, it should fill the screen.
