Having problems with your Dell Inspiron 1521 Laptop ?

My dell keeps turning off my RGB external display

\015 I have a Dell Inspiron 1521 laptop with a ATI Radeon Express 1270 video card. I just purchased a 37 inch Vizio TV and I am trying to use the RGB function to extend my PC display onto the tv. My comp recognizes everything and it displays my extensin on the tv but it will only run for a short time and then it just shuts off the external display for no apparent reason. What's even stranger is that the computer doesn't seem to recognize that the external display was turned off, no unplug notification...nothin. The only thing I can think of is that the laptop runs too hot with an external display as big as the tv is and shuts it off. If someone can please tell me if I'm right or wrong and/or how I can maybe solve this problem, it would be greatly appreciated!\015
