Mitsubishi HC6800 Post Calibration Grayscale

When done with the calibration, the HC6800 achieves color accuracy about as good as any other projector recently reviewed, including the JVC DLA-RS25

Gamma settings

Mike put it this way. The default gamma is almost dead on, averaging 2.18, with unusual tendencies.

Dynamic Iris

The dynamic iris is nicely done. I've found it to be one of the least noticeable out there. In fairness, though, the blacks, being not that spectacularly black, might indicate that the range of the iris isn't particularly great. And in that case, it's easier to make iris action a bit less detectable.

Mitsubishi HC6800 RGB Settings

These are the adjustments we made to Red, Green and Blue for the grayscale balance.
Calibration of best mode is saved on AV Memory 1.
Default settings for all is 0.

You may only choose from Cool, Warm or Medium as a starting temp in User. Medium color temp as reference in User.

User 1 gamma is set with RGB at 6 on Low, Blue at –1 on Mid.

Output at 100 IRE 578

Since the High Brightness cannot be adjusted, we could have created an alternate "brightest mode, with other combinations, although that would have kept maximum brightness under 800 lumens. We'll leave that to you.
