I would like to know if there is any standard or feature which allows desktop LCD monitors backlight control setting in software. I would like to know what I should be searching for. This is a pretty common feature of laptop computers, but I'm not able to find an equivilant for desktop/standalone monitors.
I have tried a few 'sofware only' solutions which effectively just control the brightness sent to the monitor - not the backlight of the monitor itself.
Of course I can change the setting easily by using the OSD of any monitor but this is not always convienient to change.
