LCD Monitor Calibration: Lightroom 3 & CaptureOne 5 Pro

Ian, a white luminance value of 120 cd/m2 is normal for a LCD screen. As I said before, the black luminance is extremely important. You must have it at 0.34731% of the white luminance (0.42 cd/m2 for a white luminance of 120 cd/m2). Setting in Adobe RGB colour space white luminance at 80 cd/m2 is too low to get 0.42 cd/m2 (*). You must be missing black levels

 

For instance, using this online test Monitor Calibration Tests: Black Point I can start seeing black levels starting at RGB=(1,1,1)

 

 

 

Maybe this help: LCD monitor test images

 

(*) Just for information: In my monitor, to get a black luminance of 0.42 cd/m2 at a while luminance of 120.0 cd/m2, I had to reduce the contrast control at 8 and the brightness control at 53 while RGB channels are: red=54, green=37, bue=37

 

Interesting stuff! Using the black point test I can definitely see changes from 2,2,2, not 100% sure if I can see 1.1.1 but then I cannot remove all extraneous light sources, I have a window to the left/behind the monitor and another at 90º to the right. I have pulled down both blinds but they are not light-safe.

 

I might have another go at re-caliberation this evening. I have an EyeOne and use ColorEye Display Pro software.
