I cant change any settings for the game because after i click play on the launcher my screen goes black and then i get my blue box that says no signal. i have already right clicked on my desktop, selected resolution and changed it but it still does not work.

no i think its my screen, i tried do everything i can and idk what to do since im not that good with computers.

the cpu is an i7, 6 gigs of ram, and the video card is a 4870x2

I just got a new computer tower and hooked it up to my 26" sanyo tv monitor, but when i start the SWTOR game all i get is a black screen and a blue box moves around saying "No Signal" i can hear everything from the game, but no picture, please help!
