Panasonic PT-AE4000 Basic Settings

Posted on October 1, 2013 by Art Feierman

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.

Contrast = (0)	1	-1	0	0	-2	0	0
Brightness = (0	1	1	1	4	4	4	7
Color = (0)	0	0	0	0	0	-5	0
Tint = (0)	0	0	0	0	0	-4	0

Lamp Mode=High (unless noted otherwise)
Lens aperture fully open
All other settings at default (untouched)

Zoom set at mid-point for all measurements

To get the very most out of the DLA-PT-AE4000, a calibration is necessary, but will only yield a slight improvement over Color 1mode. Calibrating the individual colors will further improve and should eliminate the slight red push.

hat is truly a superb set of numbers! Only a 40K variation across the range from dark gray to white, and about as close to 6500K as you will see. Mike placed the calibration settings to get these numbers in the Memory 1 of the Panasonic (which offers more than a dozen savable memories.

Gamma settings:

The gamma controls on the PT-AE4000 allow for detailed customization, including different gamma curves for each primary color! You can have about as much fun as you would like, customizing gamma for your screen, room conditions, personal tastes, etc.

The measured default gamma averages 2.15, pretty close to the "ideal" 2.2. With the advanced gamma controls you can furthter tune the gamma.
