ViewSonic PJD-7828HDL Projector Review – Advanced Calibration: CMS Calibration, Calibration Charts
ViewSonic PJD7828HDL Movie Mode Pre-Calibration CIE 1976 Saturation Sweeps (target REC 709)
ViewSonic PJD7828HDL Movie Mode Post-Calibration CIE 1976 Saturation Sweeps (target REC 709)
The good news is the PJD7828HDL does provide full CMS controls, the bad news is they do little to help the poor performing color gamut. Red, blue, magenta and yellow were 4 colors I was able make slight improvements too, green & cyan not so much. The end results exhibits both green & red under-saturated at 100% and running towards yellow. Blue is a little over-saturated at 20, 40 & 80%. Cyan’s hue control did not work well so I left it alone. Also, it could not achieve 100% saturation, the best it could do was 80%. Magenta’s 40, 60 & 80% saturation levels were very high with the 80% level reading 100%. Yellow fared the best with just a little error in hue at 100%.
