Optoma HD806 Projector Review
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.
Optoma HD806 Color Temperature
First, here are the color temperture measurements for the Cinema mode, right out of the box
Very good, but they can be improved a bit.
Optoma HD806 Basic Settings
|Our final settings (numbers in parens are the default numbers):|
|sRGB (52) User||(50)|
|adjusted for User mode to 47|
In addition to calibrating Red Green and Blue for a correct grayscale balance (6500K), there are a number of other settings that come into play. Typically Contrast and Brightness (white balance and black balance), need to be done first. Color saturation and gamma also need adjustment.
Mike did not adjust saturation.
All other settings are at their defaults for those modes.
Zoom was set at mid-range, All other settings at default
Optoma HD806 Post Calibration Grayscale
|Pure Cinema Mode:|
|White (100 IRE)||6752K|
|Light gray (80 IRE)||6553K|
|Medium gray (50 IRE)||6609K|
|Dark gray (30 IRE)||6489K|
The HD806 produced good post calibration results, with a resulting good picture, but this Optoma does not calibrate particularly well, and most other projectors can produce output consistently closer to the ideal 6500K. That said, the picture color is very good, and very watchable. Here are the measurements after calibration, for Pure Cinema Mode:
Gamma measured to 2.28, pretty close to the ideal 2.2 for movie watching. We did not measure different degamma’s (Film, Video, etc.) Video, however nicely lowers the gamma to give a big more brightness to the mid and darker areas for better TV and sports type viewing.
