Thunderbolt Dock Display/External Display not functioning #20

My XPS seems to crash and restart every time I plug in an external monitor. External keyboards and mice work fine through the dock when connected to a non-thunderbolt port. HDMI and DP both seem to crash it, I have nothing else to try and test.

What I've done

HDMI & DP on dock w/ thunderbolt port -- no response (KB&M dont work either)
HDMI & DP on dock w/o thunderbolt port -- crash (KB&M work)
HDMI on included adapter -- crash (KB&M work)

I've added "agdpmod=vit9696" in boot-args. Display Port on dock with thunderbolt port now works for me. HDMI still not working though.
