Bug Description
Hi all,
I have a NUC7i7BNH with the latest BIOS (0062) running Ubuntu 18.04 (uname -r = 4.18.0-15-generic). I have the NUC connected via USB-C to a dual DisplayPort adapter, to an Avocent SV340D KVM.
If I have the KVM on the switch for the NUC, everything works great. If I switch the KVM to another channel, and then switch back to the NUC, I only get black screens. The only solution is to hard reboot the NUC.
Any help would be appreciated.

@Update: Disabling DP1.2 and DDC/CI on the monitors seems to solve this. The monitors are Dell U2415.
