NUC 6i5SYH No HDMI output

I installed sierra on my nuc.

the issue i am having is that HDMI out is not working at all. if i have it plugged in on boot, i get the NUC splash screen, it gets to the apple loading screen, but then locks up and fails. there is no issue with mDP plugged in. If i boot with mDP its fine, but if i plug in HDMI while powered up, i get nothing. sometimes the monitor says theres no cable, other times it says its going into sleep mode. i have tried many cables, and 3 different hdmi monitors.

any suggestions? id really like more than one monitor
