MacBook Air M1 not connecting to an external monitor issue.

My MacBook Air M1 currently runs MacOS Ventura 13.01.1. I am experiencing an issue in which my MacBook's screen will not be displayed on my external 4k monitor. I have doubled checked that both my monitor and the USB dock work with my friend's MacBook Pro which is able to connect to my monitor successfully. My MacBook screen will only show the wallpaper when connected to it and I am also unable to use the mouse arrow, leaving It useless as the monitor screen continues to stay black.

When I then unplug my MacBook from the USB dock my windows come back and the screen turns back on, showing the display settings preferences window with both my MacBook and my Acer monitor shown as usable displays. It then disappears after a couple of seconds before I can click and change any of the display settings.

I have googled what to do multiple times and have tried solutions to display problems and bugs such as turning my display and MacBooks power off and resetting my parameters RAM etc and nothing seems to fix it.

Any advice would be much appreciated :)

Thanks
