GPU
1 x HDMI to 5K screen (fine)

For last output, USB-C to USB-C to dock then:
1 x Display port to VGA
1 x HDMI port to DVI

The two screens through the doc mirror not extend. I've installed the DisplayLink software but it says no monitor detected.

Can anyone help, pls?

Note from moderator:
I moved your post into the macOS section of the forum.

The device you are using --> https://hypertec.limited/connectivity/prodockextreme/ does not appear to have DisplayLink technology inside, so DisplayLink will not be able to help. This is why the DisplayLink software says, 'No monitor detected'.

Based on your description of the behavior, the Hypertec device uses an internal DisplayPort MST hub in order to power the connected displays.

DisplayPort MST hubs are not supported by macOS, which is why the displays connected to the device are in mirror mode and will not extend.

In order to connect more than one external display to an M1 Mac, you will need to use a device that has DisplayLink technology.
