I connected my Macbook Air M2 to an external monitor via the WD15 docking station and it worked for me all weekend. Today, I plugged the docking station into my Dell laptop to do some work and when I plugged it back into my Macbook, it's not working anymore. The Macbook is detecting the display but the monitor is saying no display detected.
MacBook Air, macOS 13.6
Have you tried any of the usual trouble shooting?
Disconnecting and reconnecting the display cable.
Power down monitor, wait 30 seconds or so then power up.
With everything connected to the dock, power down the dock, wait 30 seconds then power up the dock.
Disconnect the monitor cable, disconnect the Mac, then power down the dock, wait 30 seconds then power up the dock. Then connect the Mac and the display in different orders.
Have you tried different cable from Mac to dock.
Also, are you attaching the dock via the same USB-C cable that worked before?
Some USB-C cables are suitable for video … others only for USB data … still others, only for charging.
Just to check – you are using just a single monitor with the M2 MacBook Air?
External monitor connected to WD15 docking station doesn't work with Macbook Air M2 anymore after connecting it to a Dell laptop
