Likewise. Currently I have a HP Z27 27-inch 4K UHD Display. I just connect the cable (USB-C) and it works. I have adjusted the scaling manually for personal preference. No issues (even in the past with other monitors). At work we also got a batch of LG 27" Class 4K UHD IPS LED Monitors (27UK850-W). Again, just work. The main thing to note here is I picked these monitors because it only requires a single USB-C connection for display and power.
