LCD TV loses video and sound signal when I launch a game

[redvandam]

Hello all,

My problem is that when I launch a game using my LCD TV as a monitor, it loses video and sound and I am left with a blue screen as if the TV has no input. If I alt tab to the desktop, I can hear the sound from the game.

I am using a 32ft and a 15ft HDMI cable combined to connect my TV in the living room to my TV in my computer room. As I write this, I am using my TV as a monitor. So it works, but something is preventing it from launching games without losing the signal.

This system has worked in the past on other games. I am not sure what's changed since I've last tried it.

My TV is a 32' LCD and I am using a resolution of 1280 x 720 which says it's the recommended setting.

Any suggestions?

Just to make this even more confusing, some games will launch no problem and some won't. For example the Witcher 2 and Mass Effect 3 both opened and I was able to play both.

Games like Terraria, New Vegas and Civ 5 would all go to a blue screen (which I take to mean it's lost it's signal) after I launch the game through my desktop.
