change the monitor brightness

naveenisback · 02-08-2010, 06:25 AM

Hi

I wanna write a c program which reduces the monitor brightness(monitor screen has to become dim).
So I want to know is there any command or api to dim the monitor.

Please dont suggest xgamma -gamma "value".
because it does not make the monitor dim. just it reduces RGB values.

And that API or command must work for lcd, CRT, Laptop monitors.

Thanks
