Black screen

[Timthefox]

I have a big problem. I've begun with a bartop arcade cabinet for
a school project and downloaded the recalbox. Everything worked fine, but when i want to play a game, the monitor goes black. I can see the menu and all the installed games but i can't play games.
Please help!

@Timthefox Screen type, recalbox version please ... I guess you should have read the wiki first ...
