I've been trying to connect my laptop to my tv in order to watch movies on my tv but i've been having some difficulties. After setting everything up I can get my computer's display to appear on the tv for a split second but then it disappears and the tv's screen turns blue again. My laptop is a Dell Latitude D830 running 32 bit Vista and my tv isn't exactly the newest tv around. The only inputs on my tv are composite rca inputs. I've been using an s video to rca cable to connect the two but again...nothing works so far. I've been looking online for a while and haven't found anything to help solve my problem so any help would be greatly appreciated. thanks!
