Well I have one and I've used it on a TV. I've always had problems with it connecting but after many trys it does. I've tried it on other PC an Acer and an Alienware and it those devices couldn't see it at all. I got it on sale for 29.99 around christmas. They did do a firmware upgrade recently so I'm not sure if it's better. I also bought the mini Display port to HDMI cable which works better if you have a TV thats connected to a home theater unit.
