That I can think of would be a poor picture from the video card once you get it set up on the TV. You can study on how to get the picture from your video card onto the TV and then you must pick the right resolution for the TV to display the picture properly. Other than that, I see only a satisfied user.
I recently obtained a s-video to composite converter cable to use my television as my monitor. I have an e-GeForce 7800 GS video card, and my TV is a non HD regular old box set with composite plugs only. A friend of mine suggested that I not try this as it could cause problems. I just would like a second opinion.
