With Color Space set to Auto the projector produced a fairly accurate BT.709 color gamut. Red did exhibit some over saturation across all levels except for 100%. After calibration, using the RGBCMY (CMS) controls the color gamut improved into a near perfect BT.709 triangle across all saturation levels, except for blue which fell a little short of its 100% saturation target. Overall, I was pleased with the Best Mode calibration using Natural mode.

Like last year’s HC4000 the HC4010 does quit well reaching the DCI/P3 color gamut using Digital Cinema mode which employs a color filter. Because the pre-calibration white point is a bit blue it pushes all of the colors in that direction. After performing the white balance calibration all 6 colors did improve a bit but still some were over saturated at their mid points (20, 40, 60IRE). After my CMS calibration some of those errors were improved while others were not. Yellow for example exhibits a weird ping-pong effect with 40 & 80IRE moving towards green and 60 & 100IRE moving towards red. All I can do is set them to the best average. Gamut wise the HC4010 did quite averaging over 95% DCI/P3 coverage. Red was the weakest maxing at 91%. Overall post calibration performance is excellent for DCI/P3.

CMS Settings for Brightest Mode 4K/HDR – Natural

As expected, the DCI/P3 color accuracy is not so hot using Natural mode (no color filter). Except for magenta most colors reach only 80% saturation. Green, red and yellow are also problematic with 80% and 100% saturation levels measuring near the same (80%). Calibration does little to fix these errors. What calibration does improve is the hue and brightness levels but overall there is minimal difference pre & post calibration.
