I am trying to hook up my 52" Sony Bravia LCD TV to my Desktop computer and it is saying no signal. I am using the DVI cable to do so. The computers desktop will show up on the LCD screen for about 3 seconds then just goes black and says "no signal" at the bottom of the screen. Does anybody know a solution? I've tried hooking up he LCD to a normal desktop and it works fine but when i plug it in to the TV it doesnt work at all. I've also tried putting it on several different screen resolutions but nothing seems to work. Any help would be great, Thanks.
