We have a DN660. I wrote a program that displays a rainbow by drawing 8 pixel wide vertical strips with colors ranging from (HSL color space) (0, 100, 50) to (360, 100, 50). Everything with a green component looked a little funny. So I changed the program to display a continuous tone going from RGB = (0, 0, 0) to (0, 255, 0) and although i did get a continuous tone from black to bright green, it appeared a little bit like corduroy, in that it seemed to have alternating strips of dark and light. If I changed it to use red or blue, (0, 0, 0) to (0, 0, 255) etc. it displyed a smooth a transition from black to red (or blue) as you could want. So whats the story with the green ? Its an 8 plane 660, with a Mits. monitor. This isn't exactly vital, I'm just curious.
