Unable to set up dual monitor in CentOS 6

I need use two different X11 DISPLAYs for two different UI application on two different phisical monitors. Each application on each monitor.

Configuration:

• VDI output: Acer K192HQL
• HDMI via VDI output: PHL 193V5
• OS: CentOS release 6.9 (Final)

Here is Xorg configuration:

        Option "OffTime" "0"
EndSection

                Modes    "1280x1024"
        EndSubSection
EndSection

Here is the output of xrandr:

So, as you see I have just Screen 0, but I need two screens for send each application to it's dedicated screen (DISPLAY).

Also I have this message in system settings:
