Is there a fixed range for the gamma value in displaysystem?

as the topic says, i know that the default value is 1, but is there a minimum and a maximum value for gamma?

This is old… but in case anyone needs help with this…

Gamma must be greater than 0. (default 1)

Brightness can be -1 to 1 (default 0)

Contrast must be between 0 and 1 (default 1)

There's also more issues and considerations (against our opengl binding) listed here:;wap2

cool thx~  :smiley:
