Connecting three external monitors to Macbook Pro 2019 with Dell WD22 dock
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:
[U]Macbook[/U]
Macbook Pro 2019
tech specs MacBook Pro (16-inch, 2019) - Technical Specifications (UK)
- 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)
[U]Software[/U]
DisplayLinkManager 1.9.0 (Build 148)
- 'no DisplayLink-enabled display detected'
[U]Displays[/U]
3x Dell U2520D (2560 x 1440, 25")
[U]Dock[/U]
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.

Do you have the latest DisplayLink macOS software?
There is a recent firmware update for the dock, but does it matter if you're using a Mac? You'd have to install it using a Windows PC, even if it does support macOS.

I am told that the Dell WD22TB4 docking station does NOT have DisplayLink USB video technology so I cannot use this software workaround to connect 3 screens to one port on my Mac.
I am also told my Macbook Pro is limited to two screens per Thunderbolt port, hence the need for the DisplayLink software workaround.
I will have to return the Del WD22 dock. Do any of you have a link to alternative products that DO have DisplayLink technology? Either Dell or another manufacturer.
