Hi,

I am trying to connect three external monitors to one port on my Macbook Pro in clamshell mode, but the best I can get to is two extended displays and the third only mirrors the second.

My set up is as follows:

Macbook
Macbook Pro 2019
tech specs https://support.apple.com/kb/SP809?locale=en_GB
- 2.3 GHz 8-Core Intel Core i9
- AMD Radeon Pro 5500M 4 GB
- Intel UHD Graphics 630 1536 MB
- 4x Thunderbolt 3 ports
- MacOS Ventura 13.6 (22G120)

Software
DisplayLinkManager 1.9.0 (Build 148)
- 'no DisplayLink-enabled display detected'

Displays
3x Dell U2520D (2560 x 1440, 25")

Dock
Dell WD22TB4 dock
2x Displayport cable from monitor to dock
1x USB-C cable from monitor to dock

I read that you can use DisplayLink software to compress output and connect more than two displays to a single Thunderbolt port. However, I cannot get it to work.

Can any of you experts please advise? If the Dell WD22 won't work for whatever reason can you suggest a dock that will?

Many thanks.
