I have a Dell U2723QE monitor which is daisychained to another smaller monitor. This monitor has Ethernet cable, connections to my keyboard and mouse and I would generally just plug whichever laptop with usb C cable and they'll start working.
Dex on the other hand on my S23 ultra starts showing up on the secondary screen, however, I want it on the main monitor. So I would disconnect the secondary display and it'll just not do anything at all. It'll give a notification that external screen detected but won't show anything on it.
I can see Ethernet and mouse etc working with phone when connected. I thought it might be monitor related so I reset the monitor as well and disconnected all other wires but still wouldn't work...
Any recommendations?
