Hello all! I just set up my first retropie, and I’m having an odd problem.
Everything seems to be working fine, but whenever I open a game (only used SNES, but this may be true on other platforms too), I get a blank screen; I get audio but no video. What’s weirder still is that if I unplug and then re-plug in my HDMI cable the image comes back. Even weirder than that is turning off/on my TV, or even switching the input on the TV, fixes the problem as well.
I get this same problem when I exit the games and try to go back to emulationstation.
I might want to add to this that I’m getting some overscan (I don’t have it on); I can see about half the lettering on the options/menu/etc.
