[Ubuntu 18.04.1 LTS] DLM Not allowing me to set 1080p resolution

[mrbmi513]

Update: This set of steps is the workaround to resolve this issue.

1. Plug display into laptop
2. Unplug dock from USB
3. `sudo systemctl restart dlm`
4. Unplug Monitor from laptop
5. Plug dock back into USB
6. Plug Monitor back into dock

Obviously, this is far from ideal.
