Hi Damien ,
I have a LCD monitor (LG-Phillips Slimax MF151S) . After many attempt to calibrate monitor (with x-rite calibrator and your method) I can't access to right Black Luminance .
When I reduce amount of brightness by button on screen (30) , Black luminance is 0.311 and luminance is 64 . In this situation shadows in my images match to print but screen is a bit dim !!
And when I set brightness to higher values (90) , Luminance is about 100 but Black Luminance is 0.492 !!
in both calibration results the Contrast Ratio is the same (About 200).
How can I get Luminance at 100 and black luminance about 0.300 ?!
before x-rite I used Adobe Gamma and I could set the highlights, mid-tones and shadows match to prints !!!
I,m waiting for your reply,
Thank you in advance.
