RPCS3 shut down my monitor

I played Battlefield: bad company 2. it's on a really good state now. mostly 30 FPS even on 4k. but sometimes when you running it, you see error message and sometimes randomly freezes in the middle of the game. I assume that those are normal problems in that stage.

But i just encounter a weird problem, that in the middle of a cutscene the monitor just lost signal on the dvi port. the only why i found to make it work again,  is to restart the PC manually
