Dear Graeme, is it please possible to modify the Dispcal output from Adjust R,G & B gain to get target x,y. Press space when done. Target Br 125.00, x 0.3324, y 0.3410 / Current Br 125.64, x 0.3345, y 0.3417 DE 1.2 R-- G+ B+ to: Adjust R,G & B gain to get target x,y. Press space when done. Target Br 125.00, x 0.3324, y 0.3410 / Current Br 125.64, x 0.3345- y 0.3417- DE 1.2 R-- G+ B+ ^ ^ This means adding "+ - =" also to the x and y readings. As mentioned, my monitor (NEC PA series) allows to modify the x,y coordinates. While adjusting, the first line with the target values is fast getting out of sight, because of the scrolling display with new readings. It would be a lot easier with additional "+ - =" to show the right direction. ;-) Regards, Juergen
