xrandr: Failed to get size of gamma for output default

[akbwyfc]

Hi

I have centos 7 and my device does not recognize the monitor,
So I have the only minimum size now.

My monitor connected to PC using display port (not HDMI).

I installed autorandr:
$autorandr --save mobile
xrandr: Failed to get size of gamma for output default
Saved current configuration as profile 'mobile'

When I run xrandr I have:
$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 76.00*

Also the following does not work
$ xrandr --addmode 3840x2160
bash: HDMI1: No such file or directory

Would be thankful for the help.

Cheers
