Control the monitor's brightness using powerdevil on pc desktop.

Hello.

I,m very newbie using linux in desktop pc, before i,d used linux on laptops with sleep option available. Well, currently I am using linux on a desktop pc with external hdmi monitor, and I,m not able to control monitor's brightness using kde systemsettings powerdevil to increase or decrease monitor brightness, the brightness control just doesn,t show up in kde systemsettings  

If i try to control monitor brightness using xbacklight command, this is what I get : No outputs have backlight property

If i go to /sys/class/backlight  the directory is empty   . I can use the monitor's built in controls to increase or decrease brightness, but I would love to know why I cannot do it using kde powerdevil or xbacklight like i used to in laptops.

Regards.
