Hello. I just installed batocera on an SD card, running on an old acer laptop. I tried hooking the laptop up to a secondary display (my tv using VGA), and for a while it worked! And then I messed around with the configuration a bit, and now it will only display on my laptop.
I've done a clean install, tried every "global video setting" i can, etc. It worked before, and now it won't no matter what I try. The TV only displays a white screen when in ES, and the games are cut in half when played(half on laptop monitor, half on tv).
