The already-announced Hades Canyon NUC has 2x DisplayPort, 2x HDMI 2.0a and 2x Thunderbolt 3. That amounts to six ports capable of driving a 4K display. Thunderbolt 3 ports can drive two 4K displays at 60Hz if the controller supports it.

I suspect that other products using this processor will be less generous in terms of connectivity, simply because it's total overkill for the overwhelming majority of users.
