Macbook pro 13" (2018) compatible external monitor
I'm using the DELL U2414H since 2014 on different MBP and MBA, which is a 24" predecessor of the one you mentioned. I haven't had any connection or display issues, and would recommend Dell displays especially for their great value.

It works best with this USB-C to DP cable, because the screen is set to auto sleep when the macbook is locked. Connecting it via HDMI also works, but when you lock the MacBook you have to turn off the Monitor or wait till the monitor puts itself to sleep. I used to use the Apple Multiport Adapter.

I think you won't have connection problems when you use a high quality HDMI adapter or connect it via a USB-C to DP cable.
