I’m building a 2018 Picade, Pi 4. The SD card has RetroPie 4.8.
All of the text on the screen is flipped horizontally.
I have tried adding the following to the config.txt file but nothing changes.
• display_rotate=1 (2 & 3)
• display_hdmi_rotate=1 (2 & 3)
• DISPLAY=:0 xrandr --output HDMI-1 --rotate inverted
I have plugged the screen into a different source and the image remains flipped horizontally.
When I plug the Pi into a different monitor, the screen reads correctly.
Sounds like this is a hardware issue? If so, how do I fix it?
I’m new at this and am at a loss. Any advice is appreciated. ty
