Average Gamma:        2.17

Mike’s Notes: None of the preset gammas gave you anything close to 2.2, so the custom gamma settings must be used if you want a gamma in the 2.2 to 2.3 range.  The High Bright color temp cannot be selected as a reference color temp in the A/V Memories, so there no way to get a high brightness quick cal, but the High Bright color temp adds so much green, you wouldn’t want to use it anyway.  The best bet is to use the Cinema mode with Brilliant Color turned on (which makes it pretty much the same as Game mode) if you need extra lumens for daytime sports.  Another option is to turn Contrast up to 10, which gives you another 100 lumens in Cinema mode.

More of Mike’s comments:

There are two color gamut settings (see the CIE charts), Wide and Normal, with the main difference between the two being an oversaturated Green on the Wide setting.  As a result, colors don’t change much going from one gamut to the other.

Editor’s note:  Mike did a full calibration, including calibrating the individual colors.

Look for that additional information/settings, graphs, including CIE charts, and Mike’s comments on calibrating the Color management system, in our new calibration pages to be found in our redesigned website come May 2013.  This additional information (and much more) that we have never previously published will be reserved as extra value for our future subscribers. We hope you will become one.  -art

    I do not see anywhere in the menus to set the RGB for contrast and brightness as seen above. Is that an error or am I missing somthing?
