Can SMART be used to correct a red or blue push as measured with Avia?
There are lots of useful tests on the Avia test disk, some of which can be used to make adjustments, other are simply there to test the quality of various aspects of the display system. The color decoder test on the Avia disk is the one where one can measure red push. It is testing the accuracy of the color decoder in determining the saturation of the various colors with given input signals. This is different from color balance, which is a measure of the ratios of red, green and blue with a white signal or various shades of gray. When one measures grayscale tracking, and tweaks the various user and service mode controls that we all know and love, one is trying to make sure that this ratio is right, and does not change with IRE level. When we add colored filters we make adjustments to these same controls to restore this color balance. So color balance is about making white and grays having the right amount of red or green in the white and gray parts of the image. Too much red, and the w
