The dila being origionally designed by hughes electronics
for the goverment has tons and tons of adjustments, black
level, white level, and gamma. A tweakers dream.
Some if not all of the dlp's have adjustable gamma too.
Of the lcd projectors i own both of which are made by sharp
there are only two adjustments on each panel, esentially a
black level and a gain. Similar to low end crt projectors.
So there is little room to adjust stuff.
