I know that the palette for DSTN is lower than that of TFT, but I have
my DSTN going at 64K colors (no palette, if memory serves me right), and
I have the Chips & Tech 65545 (on the 701). The colors look better than that
on my server, but that monitor is about 7-8 years old. I think that maybe
the DSTN is limited on colors because it scans constantly, rather than having
each pixel individually lit up. Anyone- correct me if I'm wrong.
