This is my first post here. I'm at the beginning of the road called Raspberry Pi.
Is there any way of changing the gamma/contrast/brightness of monitor via Raspberry Pi?
My Samsung 960BF doesn't have any hardware adjustment, only a power button.
I tried using
xbacklight and got error
"No outputs have backlight property".
gddccontrol also didn't work. Error:
I/O warning: failed to load external entity "/home/pi/.dccontrol/monitorlist" Document not parsed successfully Probing for available monitors"
And nothing is happening.
I connected my monitor through DVI-HDMI cable. Maybe this is why it doesn't work?
I'm using Raspberry Pi B+ V1.2 with Raspbian.
