Maybe, but we'd need some details about the "lead" you bought. And it should also be mentioned that many people get these fanciful ideas of being able to use a TV as a cheap replacement monitor, and usually those fantasies are dashed on the jagged rocks of reality as soon as they turn it on for the first time.
If you're using a high bandwidth connection like HDMI or DVI, it is acceptable for short periods of time, but any other connection is pretty much a complete waste of time.
hi i've just purchased a lead that runs from my pc to my tv through rgb, but i cant seem to get a picture on my tv can anyone help please??? many thanks, sam
