Hi.
I know how to change brightness (or backlight) on LCD (as someone wrote howto, using PWM). Is it possible to change contrast on e.g. 10" LCD?

Thanks.

Not in LCD itself and you can only decrease it by modifying RGB output LUTs. I'm not sure if Mali has them.

TFT's generally don't have contrast controls. Some computer monitors do but they have internal circuits to do this.

Your only control will be brightness of the backlight.
