Dell XPS 9350 failing to show screen through projector

I have a usb c to vga adapter which mostly works when connecting to external screen.

When I connect it to external projector it doesnt and the projector keeps telling me it receives no signal.

I tipically add a mode to xrandr for DP-1

xrandr --output DP-1 --addmode 1920x1080

and if I do xrandr

 ~ $ xrandr
Screen 0: minimum 320 x 200, current 1920 x 2160, maximum 8192 x 8192

I can see the DP-1 connected but I cannot manage to get my second screen on it. I tried setting the second screen position in xrand as I would normally do to no avail. I also tried to go through the display config of xfce and that yield no results.

I am running the latest kernel 4.8.11-1 and the latest bios for the computer. Any suggestion on things I can try?
