Epson Home Cinema 8700UB Projector Calibration and Settings

Posted on November 1, 2010 By Art Feierman

We calibrate each home theater that is reviewed. It is a pretty standard calibration, there’s always more that can be done by some of the “hi-end” calibrators. Our calibrations, including the Home Cinema 8700UB, are normally limited to a grayscale calibration, along with brightness, contrast, color saturation, etc. We did not adjust the individual colors.

Epson Home Cinema 8700UB Color Temperature

Color Temp over IRE Range
30 IRE	6753
50 IRE	6718
80 IRE	6682

Let’s start by repeating the pre-calibration measurements of the THX mode (which is based on the REC 709 standard on the 8700UB

OK, those are excellently tight numbers, but, a little cool compared to the ideal 6500K target. Still, this much shift is pretty slight.

Those post calibration grayscale measurements are almost dazzling. Only a variation of 117 degrees over the 20 to 100 IRE range! And all of it, within 168 of 6500K. Sweet! No wonder this Epson has the most natural color yet, of any Epson UB projector reviewed!
