Mitsubishi HC6800 Projector Calibration and Settings

Posted on May 28, 2010 by Art Feierman
We calibrate each home theater that is reviewed. We perform contrast, brightness, saturation and other image adjustments, as well as a grayscale balance. A complete professional calibration can go even further, but the settings we provide generally offer a anywhere from a slight to dramatic improvement, compared to the "out of the box settings".

Mitsubishi HC6800 Color Temperature

These are the measurements, taken "right out of the box." Mike chose Cinema as our starting point for a "best" mode. Cinema is also the same as the two user savable modes: Expert 1, and 2.

To start, the HC6800 looked very good, though not really on the money. Color temp was a little cool (more blue than red), but not much in the brighter areas, moving to neutral to wam (more red than blue) in the lower ranges.

Color Temp over IRE Range (Best color temp)

Medium Color Temp
30 IRE 7929K (dark grey)
50 IRE 7236K
80 IRE 6540K
100 IRE 6583K (white)

For those interested, here are the color temperature measurements (and lumens) for white (100 IRE), for each of the preset modes, as reported on the Performance page.

Lumen Output at various Color Temps at 100 IRE

Medium 687 @ 6583K
High Brightness 946 @ 7864K
Cool 573 @ 9459K
Warm 652 @ 5937K

Mitsubishi HC6800 Basic Settings

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.
