If you usually watch your TV/projector (not sure what display you have) with lights off, you may find your current gamma at the low end (10% - 40%) will be too low (1.9 – 2.1), so giving you a flat looking of the picture (picture without a good depth).If your display allows you to adjust gamma, try to raise the gamma at the low end to the range of 2.1 – 2.2 minimum.If you can, try to adjust the gamma to be as flat as possible at 2.2.A flat and smooth gamma (just like below – that’s for my AE4000 projector calibrated for Magic TV MTV3500 playback) is the second important factor (in my opinion) for a great looking picture (the most important factor is the accurate D65 for all 0%-100% - also in my own opinion only).



If your display has a fully functional CMS, i.e. a Color Management System that can allow you to adjust the 3 aspects (Saturation, Hue, and Luminance) of all the 6 colors (RGBCMY), you can try to use the famous “75% saturation method” to calibrate the color gamut (by referencing this post -> http://www.avsforum.com/avs-vb/showthread.php?p=16166537#post16166537) - even if your display does not offer you a CMS, it's worth for you to read the post.

If you can use this method to achieve the CIE diagram which has all the measured points at or below 75% saturation levels align nicely at the reference points - just like below (never mind the 100% points),



and the Luminance of RGBCMY behaves as linear as possible for all the points at or below 75% saturation levels (just like below),



I’m sure you can enjoy the most natural-looking picture from your display (assuming the viewing is in a dim environment, e.g. all lights off).

Good luck, and good work!Enjoy!
