My current set up is the 2 Dell Monitors are plugged in to mains with a HMDI running from each monitor into the Kensington Dock.
The Kensington Dock is then plugged into mains and has a USB-C lead running out of it (which it fixed to the dock).

I'm looking to be able to plug the dock into my Macbook and for he 2 monitors to then extend the display, thus meaning I will have 3 screens to work from.

I have downloaded DisplayLink but unfortunately this is not connecting to my external monitors and still shows in my system settings as only having 1 external monitor but the macbook display is extended (and mirrored) on the 2 external monitors. This means when I drag my mouse into the one external monitor, the other monitor copies what it is doing.

Does anyone have any suggestions on how I can extend the display of my Macbook across all 3 displays?

To add to what Szymon said in his previous reply, for your reference DisplayLink technology is a combination of hardware and software. If the docking station you are using does not have DisplayLink hardware inside of it, then the DisplayLink software will not function.

According to the information provided by Kensington for your docking station --> https://www.kensington.com/p/product...#Product-specs the docking station is a USB-C docking station that uses a technology known as DisplayPort Multi-Stream Transport (aka as DP MST) in order to drive three external displays. It does NOT have DisplayLink technology inside of it.

Further to this, Kensington calls out that the dock is compatible only with Windows systems,

For your reference, Mac computers do NOT support DP MST, which is why you Mac thinks that only one display is connected and is mirroring the contents across both displays.

If you need to add two or more displays to your Mac, you will need to use a product based on DisplayLink technology. DisplayLink has a list of DisplayLink docking station products available here --> https://www.synaptics.com/products/d...cking_stations
