Acer VL7860 4K UHD Laser Projector Review – Advanced Calibration: CMS Calibration, Calibration Charts

CMS Settings for Best (dark room) calibration – Rec.709 Mode

RGBCMYHueSaturationGain
Red-10100133
Green-2096133
Blue-34107111
Cyan-49101143
Magenta4084130
Yellow-1895139

The default CMS is not that bad considering it’s before calibration performance is affected by the cool pre-calibration white balance. If you look carefully at the ‘before’ CMS calibration chart you will see all of the colors originate from the white point which is in the blue zone, this means all the colors are pulled towards blue. After correcting the white point through calibration, the hue for all the color was improved. After doing a full CMS calibration I was able to get exceptional color performance for all 6 colors across of their saturation points.

CMS Settings for Brightest calibration – User Mode

RGBCMYHueSaturationGain
Red-599167
Green-1896158
Blue-32104117
Cyan-15102127
Magenta1285141
Yellow-2797127

With Brilliant Color turned on for my Brightest calibration I expect the colors in CMS to be less accurate especially when it comes to luminance and they were. However, for some reason cyan at 100% saturation took a wicked drop towards blue. The rest of the colors behaved and calibrated quite nicely but not as good as my Best/Dark Room calibration.
