Optoma PT100 Video Projector Review
Don’t expect much from a $180 projector.
The PT100 had some pretty serious problems with color accuracy. Not only did it have inaccurate RGB curves, but its color gamut was off and it wandered warm throughout most of the greyscale spectrum.
The projector's color temperature had inconsistent spikes. It would get warm suddenly for a short band of greyscale, then retreat to an imperceptible bias. What does this mean for the average viewer? Some shades will appear more reddish than they should.
The curves in the graph below are supposed to be smooth. Smooth curves indicate a nice, even progression from dark to saturated. Inconsistencies represent at seem to have any issues with its RGB curves.
The projector's color gamut is also pretty far off. The blue and green points are both very undersaturated and shifted clockwise along the color gamut. That means blues and greens might look slightly skewed. The projector's red point is closest to accurate, but it's still a little off. The point that users are most likely to notice, however, is the TV's white point, which is very, very far into the blues.
Below we've listed our measurements for the projector's red, green, and blue points.
