Panasonic PT-AE7000 Projector Calibration and Settings
Below are the calibration settings Mike ended up with in doing a grayscale calibration, and general settings. As is typical, we did not individually calibrate the primary and secondary colors, although the Panasonic does have a full CMS (color management system).

For your convenience we repeat the Panasonic PT-AE7000's brightness and color temp measurements from the Performance page.
Let's take a look at the numbers:
Panasonic PT-AE7000 Color Temperature
Before we provide our settings, let's see what we started out with: Pre calibration, these are the color temperatures over the grayscale range:
Color Temp over IRE Range (Pre calibration – best mode):
30 IRE 6703
50 IRE 6310
80 IRE 6601
100 IRE 6550
Here's a look at the other modes, just reporting on White - (100 IRE).
Lumen Output and Color Temp with 100 IRE Field (mid zoom):
Cinema 1= 622 @ 7489
Cinema 2= 1054 @ 8170
Game= 1155 @ 9745
Normal= 1255 @ 9428
Dynamic= 1516 @ 8321
Rec. 709= 602 @ 6550
D-Cinema= 622 @ 6418
Panasonic PT-AE7000 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. In the case of the PT-AE7000 projector, most of these default settings were fairly close to ideal, with only contrast altered more than slightly in most modes.
Settings for measurements (default values are in parenthesis):
|Cinema 1||Cinema 2||Game||Normal||Dynamic||Rec. 709||D-Cinema|
|Brightness = (0)||1||1||0||2||4||3||6|
Color Temp is at default on all
Lamp Mode=Normal (unless noted otherwise)
Auto Iris Off.
All other settings at default (untouched)

Average gamma= 2.22
PT-AE7000 RGB Settings
Below are Mike's adjustments for the REC 709 and Dynamic modes. Again the goal of "best" is a great looking 6500K grayscale, and the goal of "brightest" is to improve a bright mode in terms of color accuracy, but without compromising brightness significantly.
PT-AE7000 Post Calibration settings:
|Rec. 709 (Memory 1)||Quick Cal of Dynamic (Memory 2)|
|R = 7||20|
|G = -4||-15|
|B = -2||-15|
|R = -3||0|
|G = -1||0|
|B = 2||0|
Above, MIke's spreadsheet reference to Memory 1 and 2 are the first two savable memory slots on the PT-AE7000.
