Get Fixed LCD Contrast/Gamma

\i C ? X

Returns whether the iLCD panel has a fixed contrast/gamma setting or not.

Most iLCD panels do not need to have the contrast and gamma value set, as they have the optimum values already set by the TFT panel manufacturer. In this case (fixed = 1) although the commands for reading and setting the values can be carried out, there will be no visual effect!
