Query: !!!Buyer Beware!!!

I bought this for my computer to connect to my HDTV. hooked it all up. and it didn't work. so i tried shutting down my computer and letting it detect it on start up, still no dice. went in and tried to manually switch over. no luck. trying new ideas over and over for about an hour and a half, to no avail. It clearly says in the product description that it hooks up a computer to an HDTV, and it doesn't.every review on here points the finger at disappointment, don't be fooled, this product is junk.Don't say I didn't warn you...
