WITH MAC OS BIGSUR 11.5.1.

I tested the same configuration with my macbookpro intel and it worked, however with the m1, it only works one screen and still with everything cloudy. without definition. Can someone help me?
Based on your description, it sounds like you are using the Plugable TBT3-UDZ docking station. Presuming for the moment that my understanding is correct, the TBT3-UDZ does not have DisplayLink technology inside. As a result, DisplayLink will not be able to assist in this specific case.

Intel-based Macs with Thunderbolt 3 can support up to two external displays via a single Thunderbolt 3 connection to a Thunderbolt 3 device.

The M1 MacBook Pro you are using can only support one external display via a Thunderbolt/USB4 connection to a Thunderbolt 3 device. Apple calls this out specifically under the 'Video support' section of their technical specifications --> https://support.apple.com/kb/SP824?locale=en_US

This is why two displays work when the dock is connected to your Intel Mac, and only one display works when connected to your M1 Mac. To put that another way, the limitation is internal to your M1 laptop.

In order to have more than one external display connected to your Mac, you would need to be using a docking station that has DisplayLink technology within it.
