Quoted from Jam_Burglar:
Any chance of a higher contrast on the non-sigma, full color display mode? That's my only suggestion for improvement so far. To match the brightness of my old DMD I have to turn the brightness to high, but that also turns the black levels up, making the display more grey than I'd like.
I'm guessing this depends on the panel used. Two of mine are nice and dark. The third is more of a grey background and the colors are dimmer. Regardless, it's still better having color than sticking with a plasma DMD.
