From what I have read in these forums the Avia disc will calibrate the display to compensate for the source anomaly's. Since the disc only plays through the DVD player it only optimizes that one output. The display in general will be better calibrated overall compared to out of the box.
I also would like to propose a question to someone more experienced with this than myself. Is there anyway to output the test patterns to a display device that essentially would calibrate the display without the bias of the source so that other sources such as broadcast would be closer to correct? I was thinking of playing the disc through a computer but I figure that even the computer would introduce it's own biases.
Any help would be extremely useful.
Hope that it's not rude to piggyback a question on someones thread but I think this information would be useful to ctjoe as well.
