According to the OP the screensaver isn't loading during video. (after he changed the windows setting)

Turning off the MP screensaver (or setting to lower FPS instead) should stop the screen blanking.

Thanks, i found it and changed value to 30 from 300 and my screen doesn't blank which is strange as i wanted to speedup testing process. Might increase value a little bit
