I’m running RetroPie (from the SD card image) with my Pi connected to a DVI display using an HDMI-to-DVI adapter. EmulationStation displays fine but I’m finding that I get no display when running any of the console emulators. (Non-console emulators such as Apple II and Doom work fine).
Everything works fine when I connect the Pi to an HDMI TV. Only DVI seems to have this problem. I hear sound but see no image. My monitor’s power LED blinks which suggests that it is getting a signal that it doesn’t like.
I’ve tried modifying the scale and resolution parameters in retroarch.cfg but they don’t appear to make a difference.
Searching on this and other forums, I’m seeing that most people have the opposite problem – DVI works but HDMI doesn’t.
Can anybody tell me what parameters I need to adjust?
