I have just bought a new monitor to connect, so I have duals. And I see in the settings of Display you can do Extended. I Assumed it would mean the Extended was a screen that I can drag things over there. But when I try, it's like it's locked to the one screen.
There is no "arrange" option either.
Can someone please help?
Both are connected via HDMI - one direct in the Mac, one in the adapter.
Thanks.

Your Mac mini M2 support two displays: one via HDMI and another via Thunderbolt -OR- two via Thunderbolt.
The HDMI port supports only a single display.
Which is to say, if you want to use two displays, one of them must be driven by the Thunderbolt port which also support DisplayPort via USB-C.

Apple > System Settings.. > Displays > select "Use as -------> Extended display"
Some third-party USB-C to HDMI adapters will work and some will not.
for the Apple USB-C to HDMI adapter go to > USB-C Digital AV Multiport Adapter - Apple
You will not see an Arrange.. button until the setup is in Extended Desktop Mode.
Set that dock aside and try a USB-C to HDMI adapter for the second display.

Or optionally send that LETSCOM dock back and try a different Dock.
I am using an Adapater that connects to Thunderbolt and has multiple sockets, for SD Card etc, and a HDMI on the end of it. I can make it work, but it's the means of mouse or windows being dragged across that won't work.
Can you now connect the other monitor to a HDMI that goes through the Thunderbolt?
The adapter is no longer on Amazon, but this is the full Desc:
"LETSCOM USB C Hub, 6 in 1 USB C Adapter with 4K HDMI, 3 USB 3.0 Ports, SD/TF Card Reader Compatible for USB C Devices"
How can you tell if a third party one will work? Mine has many ports on it for printer, sd card, usb and so on.
I assumed you just connect the hdmi. But I don’t see that arrange button and the extended simply won’t work.
I can't send it back - had it years.
What do you look for in the details of an adapter, to know it can handle this?
