Is the new screen a normal TV with a VGA socket & not just a PC monitor? if so, then you'll need to press the 'source input button' or menu & select VGA input.

Also, is it possible that you have plugged your VGA cable into the wrong slot (on the back of your PC) as you may have a graphics card, which should be your output & not the on-board VGA connection (which will be higher up near the speaker/mic phono sockets.
