Gamma Curve
Selected Gamma Curves
THE DEFAULT SETTING OF 2.2 is a normal and smooth gamma curve rec-
ommended for virtually all sources, producing good contrast and smooth gray
transitions without distorting colors.
THE ENHANCED SETTING elevates middle gray levels compared to
“Default”, and provides a more gradual rolled-off transition to maximum white.
Together, these differences can improve the apprearance of many kinds of
images.
THE 1.8 SETTING elevates low gray levels compared to the “Default” and “3.2” settings. In
high amibient light conditions, details can be seen in the dark parts of the image that would oth-
erwise be difficult to perceive.
THE 2.5 SETTING results in a darker image with higher contrast. The gamma curve more
closely matches the official standard for PAL and SECAM video signals.
THE 1.0 SETTING is a straight, linear transition from black to white. For normal source sig-
nals, it results in a picture of low contrast with highly elevated low-and mid-level grays. It should
be used only with sources that have their own pre-applied gamma control.
