edit: fixed it
my screen blacks out only when i play videos and game in fullscreen, i still hear the audio. When the video is playing in fullscreen it blacks out 3 seconds into watching it, i pause the vid in fullscreen then the screen turns back on. gaming in full screen is also a problem. watching videos and playing games not in full screen is not an issue. i dont think it has to do with my computer or monitor because it seems to do everything fine just not full screen video and game stuff. this was not an issue before until I moved my setup. the hdmi and power cable for the monitor are in all the way. please help thanks
