I'm using 1.3.0 drivers. 2x DP for UP2715K and 1x HDMI for P2418D. The ones that connected to HDMI works perfectly fine but 5K is showing screen like this: https://cln.sh/Nvn8D7
It even sizes less than P2418D as this one is 2K monitor only. How can I fix this problem? 
This is screenshot from system report: https://cln.sh/3QICuK (it seems like it diagnose my monitor as 4K monitor, instead of 5K) |
Did you update macOS to 11.3? If yes, then there is a bug and 1080p max you can have until it is fixed.
