I used the X-rite Calibration LUT Tester (downloadable from link) to check if my calibration was loaded correctly.

I noticed, when I select the “reset video card gamma table” option from the calibration loader menu, it restored different values compared to the std flat values without calibration, see attached screenshots. Basically, instead of 0, 256, 512, etc. one gets 0, 257, 514, etc.

Kind regards,

  1. 0..65535 are the correct values (range 0..1in float, or 0..255 in 8-bit). 0..65280 are the wrong values (0..0.996109 in float, 0..254 in 8-bit).
