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.

RGBCMY	Hue	Saturation	Brightness
Red	50	29	67
Green	60	50	50
Blue	50	30	60
Cyan	50	47	64
Magenta	43	32	60
Yellow	50	41	61

CMS Settings for “Brightest Mode” – Cinema Mode

RGBCMY	Hue	Saturation	Brightness
Red	45	34	56
Green	44	33	48
Blue	53	39	49
Cyan	44	50	50
Magenta	45	27	51
Yellow	54	49	45

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.
