Hello,
Running four monitors. 1 - MacBook Pro Apple M1 macOS Ventura 13.5.1 (clamshell open) 2 - External 24" 1080p VA2759 Monitor 90 degrees (worked well) Cable = DP to HDMI Monitor 3 - External 24" 1080p VA2759 Monitor 270 degrees (worked well) Cable = HDMI to HDMI Monitor 4 - External 21" Samsung L524H Standard Rotation (adding this one) Cable = DP to DP Monitor Using a Dell D6000 - May 2021 If you look at this page it shows 4 monitors under "Displays" which is "Display Rotation and Toggle" on my screen https://support.displaylink.com/know...-apple-m1-on-m When I hook all three up external monitors up, the MacBook does see them. All seems to be working well with the MacBook. I can arrange all four monitors, mirror or extended work. I can not rotate them in DisplayLink as it only shows two monitors at a time and not all three. See attached screenshot. If I unplug one it will then show the one that was missing or middle. Tried this in Displaylink versions: Ventura 13, Monterey 12, Big Sur 11 Release: 1.9 | Jul 16, 2023 Sonoma 14 Beta Release: 1.10 Alpha 2 | Aug 29, 2023 To me it feels like, DisplayLink it not programed to display more than two monitors in this field on the MacOS versions. Anyone else with three external monitors working on MacOS? If so, could you upload a screenshot of your "Display Rotation and Toggle"? Any suggestions would be appreciated.

Dell D6000 relies on two USB graphics technologies to support up to three external displays.
DisplayLink and USB-C DisplayPort Alternate Mode, an optional USB-C port feature that requires connecting the docking station directly to a compatible host computer's USB-C port using the original USB-C cable provided with the docking station. DP Alt-Mode is used with HDMI if the other two DisplayPorts are occupied and DisplayLink is used with DisplayPorts if using 3 external monitors. If you use just two external monitors DisplayLink will handle them regardless of what ports they are connected to (DP+HDMI or DP+DP). If three external monitors are connected DisplayLink will only handle the monitors connected to DisplayPorts and HDMI will not be seen by DisplayLink driver as it will use different technology than DisplayLink. This is why you only see two monitors listed in the DisplayLink Manager - it will alsways be two monitors with Dell D6000. The 3rd monitor can be controlled by the native OS display settings - including rotation.
