Color Accuracy: Gamma, Temperature, Gamut

The gamma curves look neat at the default settings except for the minor brightening of dark halftones (the bottom left part of the diagram). The monitor displays both lights and darks without problems.

The gamma curves do not change much when the brightness and contrast settings are lowered in the monitor’s menu.

As I said above, the monitor makes the image sharp and distorts its colors in the DV Modes. Here is an example: in the Photo mode, which is supposed to be optimized for viewing photographs, the contrast setting is so high that lights are displayed the same as white. I wouldn’t recommend you to use it for viewing photographs if you care about color accuracy.

At the default settings the color temperature does not vary much between the different levels of grays, but the overall tonality is shifted towards greens. This can be easily corrected by manually adjusting the color temperature. Selecting R=100, G=89 and B=99 in the menu, I got a nearly ideal result (the Custom graph above).

The table with color temperature values confirms my words. The variation between the different levels of gray is no more than 100-200 K, which is an excellent result.

The monitor’s color gamut is roughly as large as the sRGB color space but slightly shifted upwards in the diagram, towards greens. As a result, the monitor does not reproduce red, blue and pink-violet hues purely enough, but the difference from sRGB is so negligible that you cannot see it with a naked eye.
