Display Modes incorrect when using Monitor Multiplexer.

If I bypass it, everything works and X likes giving me all the resolutions, but with it hooked up it maxes out at 1024x768 (Should be setting it to 1920x1080).

$ xrandr -q
Screen 0: minimum 8 x 8, current 2944 x 1080, maximum 16384 x 16384

If I try setting the mode manually it doesn't fly:

        v: height 1080 start 1081 end 1084 total 1118           clock   60.0Hz

If I take out the multiplexer everything works fine as it knows the monitor, but with it this is happening and it's somewhat aggrevating. Any and all help appreciated, thanks in advance.
