I just hooked up the Razorvision DVI version to my Samsung DLP. If you looked at the split screen you quickly could see the seemingly amazing difference. Upon settling in to the full screen version the noise was unbearable and the contrast was way to extreme. Shadows on faces caused them to be too dark and with light areas too light. This device is very disappointing to say the least. I watched a replay of a recorded football game on my HD DVR and the grass looked way to unnaturally green and fake. I could not seem to get the colors to my liking. It really does increase black and white levels, but even on the lowest setting it is too extreme. Sorry Belkin, this is a good try ,but not worth the money or time hooking it up. It was back in the box and returned within 2 hours.
