xrandr: Games/Apps don't recognize virtual Monitor resolution

[DocMAX]

Hello,

i'd like to use one big screen of my 3 monitors like xinerama.
In xinerama i get the resoultion 5860x1080 shown in my Apps/Games.

In xrandr i dont get it. Here is my config:

         xrandr \
             --output DP-0 --off \
             --output DP-1 --primary --mode 1920x1080 --pos 1970x0 
--rotate normal \
             --output DP-2 --off \
             --output DP-3 --mode 1920x1080 --pos 3940x0 --rotate normal 
--output HDMI-0 --off \
             --output DP-4 --off \
             --output DP-5 --mode 1920x1080 --pos 0x0 --rotate normal \
             --noprimary
         xrandr --setmonitor surround auto DP-5,DP-1,DP-3
         xrandr -s 5860x1080

Also tried to add a mode like this:

         xrandr --newmode "5860x1080"  528.25  5860 6240 6864 7864 1080 
1083 1093 1120 -hsync +vsync

without luck.

Thanks,
DocMAX
