Glenn makes several observations I share and brings up several cogent issues I chose to ignore for brevity. In any case, I am getting a DreamColor and I will post my personal impressions to the forum in hopes it may assist someone in choosing a monitor.
In terms of 10 bit vs 8 bit there has been many years of effort put into getting the best possible results from an 8 bit panel. It may take a while before the engineers can optimize dithering and other key elements in the presentation of the image for the human eye with the added available precision of 10 bits. My understanding of mathematics and visual science leads me to believe the extra 2 bits really will make a difference, time will tell if I am right or wrong about that.
