I did not look for it in the Key menus but I will get back to you on it.
Thanks. So the gamma is in the display not the card.
One clarification please. In this display, is the gamma adjustment provided globally, that is only one adjustment that effects RGB all at the same time or are there also individual gamma adjustments for each of R,G, and B?
BTW gamma refers to the display's output intensity as a function of its input signal/voltage (it is the exponent in the relationship) and is most noticable in the mid-tones (with brightness most determining the low tones and contrast determining the high tones). For physical and historical reasons, this relationship is not linear but rather a curve. Gamma is an exponent in the math and larger values move the curve to the right leaving the intensity darker for any given input.
2.2 is considered neutral for a plasma but since in some displays some colors might not track the same as others as a function of input, it is always good to have a display that allows individual gamma adjustments per primary RGB.
