Macbook Pro M3Max - Dell 6000

[arii]

Hi,
I have an issue to share screen on three display with my new macbookpro M3plus (it works with two) with dock Dell 6000.
I installed the latest Display Link Manager 1.10.3 and I updated the dock with the latest driver (10.1.2814.0, A04).

Do you have any idea ?

Thanks for your help.

PS : only hdmi display is not working
