Optoma HD8200 Projector Calibration and Settings – 2

Optoma HD8200 Post Calibration Grayscale

Post calibration, we ended up with excellent grayscale balance which was evident, when watching the HD8200.

20 IRE6563K
30 IRE6535K
40 IRE6619K
50 IRE6574K
60 IRE6532K
70 IRE6504K
80 IRE6458K
90 IRE6448K
100 IRE6481K

That’s about as tight, and as close to 6500K as any projector is likely to get.

Gamma: The closest gamma to the target 2.2 for movie viewing is Standard, which averaged 2.13, definitely pretty close.

RGB Settings

These are the adjustments we made to Red, Green and Blue for the grayscale balance of the User mode, to get the measurements listed above.

Calibration settings: (default in parenthesis)

Red Gain1 (1)

Blue Gain-1 (2)
Red Offset(-1)
Green Offset(-1)
Blue Offset(-1)

For a quick calibrate of “brightest mode” Mike recommends using Reference. He reports that after brightness and contrast are adjusted, it has the brightnest measurements, and also has the best grayscale of the “brighter” modes. He says: “It looks good, as is, but knocking down Blue Gain a bit improves the picture with a minimal loss of lumens.” I found his recommendation to work well, though I left blue alone, and it looked fine watching some March Madness basketball.
