When I connect the second display using DisplayPort it doesn't work. If your Intel NUC isn't on this list, either it doesn't use LS-PCON or there isn't currently an HDMI firmware update available.
I've read DisplayPort is the best connector to use to hookup a bigger higher resolution monitor like the Omen linked above to a computer but should I just use a HDMI cable instead? The Intel NUC and the HP Omen monitor both have HDMI ports of course and I have a spare HDMI cable. Intel nuc displayport not working Neither AMD nor Nvidia.
