Quoted from Dmod:
SIGMA 2.4 also adds a new GAMMA selection feature that modifes how dot brightness levels are mapped to the screen. The "DMD" default setting provides the same nonlinear DMD level emulation as previoius products. The new "HI" setting uses linear level mapping, to provide higher contrast between bright and dark levels.
Thank you! This is awesome!
I too would consider a no LCD option that offered the metal mounting plate for the LCD.
