A note about 10-bit color (30-bit RGB)
Getting a 10-bit capable monitor is insufficient. You also need a 10-bit video card, such as the FirePro series. In this case, once the card is installed, go to Catalyst and find the special checkbox.
Then you can see the seamless RAMP image properly.
Does it matter?
If we are all going to get hyped up about Dynamic Range and other metrics of Photo Quality, I want my workflow to be just as good.
