Suppose I've calibrated or calibrated/profiled my display using dispcal, and I want to redo the profile using targen, etc. Should I have the vgct loaded as i go through the procedure. Or, does it make any difference? Similarly, suppose I just want to use discpal -o to recalibrate, etc.. Does it make any difference wif I don't restore the video LUT to its default state? -- Leonard Evens <len@xxxxxxxxxxxxxxxxxxxxx> Mathematics Department, Northwestern University
