I was told it would work but you would not have sound only video. My preacher has been looking for one and that was the info I recieved from radio shack about this particular type of item.
i have a small adapter that does this same thing so i have no doubt it would work and yes you can hook up your tv to your computer...however you might need a simple male to male 3.5mm audio cord since i dont think this will transmit audio
