After receiving a second monitor for Christmas, I was in a bind when it came to my video output. I own a 580 GTX video card, which has only one hdmi port and two dvi ports. Seeing as both my monitors only take hdmi, this product fit the bill perfectly. I get the perfect color spectrums and response times that I'd expect with a standalone dvi or hdmi cable. If you're in a similar situation, this will solve your problem.
