Epson Home Cinema 2100 and 2150 Projector Review – Advanced Calibration

Epson Home Cinema 2100 and 2150 Projector Review – Advanced Calibration: CMS Calibration, Calibration Charts

CMS Settings for “Best Mode” – Natural Mode

Pre-calibration color gamut performance ranged from average to poor. Red, green, cyan & magenta were under saturated at 100% but over saturated at 20, 40, 60 & 80%. Green at 100% was too close to yellow resulting in lime-green. Nonlinear issues like this are impossible to correct because if I move 100% green away from yellow then all the other levels (10-80) move from their targets towards cyan/blue. Red also exhibited this same issue with 100% under saturated and closer to yellow, resulting in a red-orange hue. Cyan 100% saturation level was under at about 85%. Yellow, magenta and blue were in a little better shape and showed the most improvement from calibration.

Although red and green have hue errors at their 100% saturation levels, most video content is below 100% so real world video is not effected that much. Post-calibration corrected some errors more than others but overall colors looked good yielding natural flesh tones.

Cinema mode pre-calibration color gamut performance exhibited all of the same issues I found with Natural mode only worse with cyan & yellow both needing additional adjustments to their hue. Post calibration measured very similar to Natural mode.
