what test pattern do i use to calibrate degamma and white peaking on my DLP projector?

Question

I have an Optoma DX605 DLP projector. I have already calibrated brightness, contrast, sharpness, saturation, and hue with the AVIA home theatre basic test patterns. However there are two more settings Degamma, and White Peaking but i don't know what test pattern to calibrate these against.

Answer 1

You will need a test pattern with a gray scale in at least 10 steps. You need to make sure that your colors are "tracking" (all the steps look neutral gray). HDnet broadcasts an HDTV test pattern that includes a gray scale. You can also get test DVDs (Digital Video Home Essentials or AVIA Guide to Home Theater) which have these patterns. Ideally you should use both, because HD color encoding is not the same as SD.

Answer 2

Degamma is the another form of Color Calibration. Use it with a Red, Green, Blue screen and make it so your balanced in colors. White needs to be a clean white.
White peaking varies the amount of time that the projector uses the transition spots on a color wheel to enhance brightness, On a red- green-blue - red-green-blue type color wheel.
