U2723QE, not working with Samsung S23, USB-C

On my Dell 24" and lower resolution and lower power displays, I can connect perfectly my Samsung s23 ultra phone via USBC connection (60W charging port). It works in all combinations of settings and USBC cables that I try instantly. 

However on the much more expensive, 90W, 4k resolution ultrasharp U2723QE monitor it doesn't work. 

Tested: all permutations of power cycling both devices, cables, changing the charging settings on the monitor(all combinations) and changing resolution on the phone. (all of these combinations work in the lower tier monitor,  none work in the U2723QE)

Also a search on Google shows it doesn't seem to work on anyone in the expensive monitor only on the lower tier Dell monitors just like me.

The S23 ultra says it is connected to display but the monitor says no usbc signal found.  Exactly the same setup and cable only the monitor is the more expensive Dell one. 

Has anyone been able to connect their S23 to the U2723QE monitor? Is there a way to raise this to the monitor's technical team?
