Sony VPL-VW90ES Projector Calibration and Settings
We calibrate each home theater that is reviewed. It is a pretty standard calibration, there's always more that can be done by some of the "hi-end" calibrators. Our calibrations, including this VPL-VW90ES, are normally limited to a grayscale calibration, along with brightness, contrast, color saturation, etc. We did not adjust the individual colors.

Sony VPL-VW90ES Color Temperature
Let's start with the color temps measured for each of the preset modes, for white: 100 IRE.
Lumen Output and Color Temp at 100 IRE (mid zoom):
Dynamic= 633 @ 11437
Standard= 681 @ 9659
Cinema 1= 619 @ 7757
Cinema 2= 603 @ 7099
Cinema 3= 629 @ 7728
User= 629 @ 7743, 753 lumens with Color Temp on Custom 5
A closer look at the best of "out of the box", :best modes", Cinema 2, shows these color temps across the brightness range:
Color Temp over IRE Range (Best Mode, Pre calibration):
Cinema 2
30 IRE 7921
50 IRE 7766
80 IRE 7329
100 IRE 7099
That's definitely a good bit cooler than the ideal 6500K.
Sony VPL-VW90ES 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.
Settings for measurements (default values are in parenthesis):
All other settings at default.

Please note, Mike's settings for User call for color saturation of 48. I've tried to watch at 48 and find it too saturated, or a combination of too contrast and saturation. Judging it by eye, I wasn't happy until I had the saturation down to the 41-44 range. It sure made a difference.
Sony VPL-VW90ES Post Calibration Grayscale: User 3 (based on Cinema)
Color Temp over IRE Range (Post calibration):
20 IRE 6116
30 IRE 6519
40 IRE 6634
50 IRE 6653
60 IRE 6620
70 IRE 6560
80 IRE 6477
90 IRE 6436
100 IRE 6552
Average gamma= 2.23
Mike NOTES: Results were almost identical to the VW85. The grayscale was further off than the VW85 with default settings, but the VW90 has a lot of hours on it.
Art Adds: The projector arrived with over 200 hours on the lamp. That probably already cost Sony about 5-10% in brightness. Keep that in mind.
RGB Settings
Calibration settings for User: Iris off, all other settings same as pre-calibration or as stated below.
Calibration settings for User:
Color Temp on Custom 4, Iris off, Gamma on 5, Color Space on Normal, all other settings on default or as previously stated.

And that covers all the settings Mike came up with and I got to enjoy!
