After purchasing a new monitor a DP cable was required and it connected flawlessly to the TB3 connectors in the new 2019 16" MBP. I was able to connect 2 ASUS PB328Q monitors capable of outputting 75Hz and only had a rare issue closing the lid to use external monitors, only when the one connected monitor suddenly started flickering. This was fixed by simply reconnecting the USB-C end to the MBP. I haven't seen this since, but I've only had these cables for a little over a week. Otherwise, as far as I can tell, it works great.
