This is useful in setting up a display for evaluation, testing, or to recover a display that has a strange set of Video LUTs (RAMDAC tables) loaded.<br> <br> Optionaly it can be used to create a non-linear calibration file, useful for diagnostics. Each of the Red, Greed and Blue curves can be given a gamma (power curve) shape, and scaled to a maximum other than 1.0.<br> <br> </body> </html>
