SONY VPL-HW40ES PROJECTOR – ADVANCED CALIBRATION INFORMATION: CMS Calibration, Calibration Charts
As usual, Sony has provided a very accurate BT.709 color space, in addition to three wider gamut color spaces. As far as picture quality is concerned, the different color spaces used by TV and Cinema Film 1 make for more saturated colors and may be desirable depending on the source.
There is a CMS included, but the BT.709 color space is so accurate that only a few minor adjustments to red and yellow improved the chromaticity error. The improvements are so slight that they are not able to be discerned by the naked eye. The adjustments are as follows (default = 0):
Before adjustment, the highest chromaticity error was 3.6% for Yellow hue, which is pretty good for CMS adjusted colors and excellent for a default color space. After adjustment, that dropped to 1% and no other error exceeded 2%. In any event, the picture quality is excellent. Previously, I said the HW55ES was the most “plug-and-play” projector I’ve seen, but the HW40ES takes that crown.
