Thanks!

According to the information provided by StarTech, the docking station you are using does NOT have DisplayLink technology inside of it. As a result, DisplayLink will not be able to help you.

The StarTech docking station you are using is based on Thunderbolt 3 technology, and relies on the host computer's internal capabilities to drive the external displays.

Your MacBook Air (M1, 2020) laptop has an internal limitation in that it can only drive one external display via a Thunderbolt 3 docking station. Apple calls this out specifically under the 'Display Support' section of their product specifications here --> https://support.apple.com/kb/SP825?locale=en_US

This internal laptop limitation is why only one display is working via the StarTech docking station.

If you want to add two external displays to your Mac, you will have to use a product based on DisplayLink technology --> https://www.synaptics.com/products/d...ylink-products
