[SOLVED|ALTERNATIVE] Tripple screen using MST mode isnt working?
Hi,
I have a strange problem with my Arch setup, today my three Dell Ultrasharp U2414H arrived. everything has setup and works perfectly on Windows8.1. However, when i boot to my Arch disk i've got a strange problem, after i started X11 (using startx) from TTY1 i got a blank screen and all my monitors go to standby.
When i disable MST (Disable DisplayPort 1.2) on my monitors X starts without problems, but then my screens are all mirrored.
Does someone knows how to solve this problem ?
Solution:
I bought 2 HDMI to DVI cables, and attached each monitor to my videocard instead of using the MST Daisy Chainging.

Not sure if this is what you mean but I use xrandr to set my monitor.
e.g.
xrandr --output VGA1 --mode 1680x1050 --left-of LVDS1
run xrandr with no parameters to find out the names and capabilities of the devices.

Thanks for your reply!
When i try to run randr (to show my displays) it says none. I guess that i first have to start X11 before randr can detect any screens/monitors.
