Epson Home Cinema 5050UB 4K Capable Home Theater Projector Review- Advanced Calibration

With Color Space set to Auto the projector produced a fairly accurate BT.709 color gamut. Red did exhibit some under saturation across all levels but this is partially due to the default white point being off its target (plus blue). The other colors were quite good with cyan and magenta having some slight hue errors towards blue. After calibration, using the RGBCMY (CMS) controls the color gamut improved into a near perfect BT.709 triangle across all saturation levels, except for red which fell a little short of its 100% saturation target. Overall, I was extremely pleased with the Best Mode calibration using Natural mode.

Like Epson’s previous model (5040UB) the 5050UB 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 2 & 8-point white balance calibration all 6 colors did improve a bit. 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 their best average. Gamut wise the 5050UB performance was exceptional averaging near 100% DCI/P3 coverage. Red was the weakest maxing at 96%. Overall post calibration performance is excellent for HDR/P3.
