Does USB-C on Gigabyte ITX mobo support video output?



I looked at giga's product webpage
- Z170N-Gaming 5: DP support is not mentioned, with a footnote '*Display feature may vary by model'.
- Z170N-WIFI: Display related stuff is not mentioned at all.
- Z270N-WIFI: DP support is mentioned, with a footnote '*Display feature may vary by model'.

I would like to see a real world example of display connection with USB-C on these boards, using USB-C to DP cable/adapter or USB-C monitor (e.g. LG UltraFine 4K)
 


I will hopefully be able to try this in the next week and report back

I have the z270m, intel i5 7500, and lg 21.5 4k(used for my MacBook Pro)....just built it haven't installed windows yet
