How can I get my Mac Mini to move my mouse between two screens?

I'm using Catalina and I've just added a second monitor with a HDMI cable. The screens work but I cannot get my mouse off the main screen to the second one. I've gone into System Preferences | Displays and made sure Mirror Display is Off and I've arranged my screens. But still I cannot use my mouse on second screen.

How do I fix, please?

Also, I use BetterSnapTool and this stops working when I plug in the second monitor. Is this related?

Thank you for your help.

The mouse goes to the edge of the first monitor, my main one, and will not go any further.

id go to system preferences>display preferences and check the arrangement tab

if the arrangement is all over the place you may not be dragging to the other monitor

or if theres a huge resolution disparity you might be dragging to where the other monitor isnt.
say for example, if i drug left from the bottom of my middle it wouldn't go over however if i drug from the middle or top of it to the leftmost monitor it would.

Thanks. I see. I think they were lined up nicely. I'll plug it back in and have a go and let you know.

If your "Arrangement" tab is similar to the above post (but shows just your two displays, of course), then in that example, the main display is the one that shows the menubar - and your only possible move is off the left edge of the main screen, and then you must move back to the main screen be crossing over at the right edge.

Ah. I didn't know that. I was trying to slide off at the left edge. Not sure if I tried going off the right hand side. I'll give it a go - thanks :)

Sorry, I mis-typed on my post, and fixed now so it shows left to correspond to the graphic in the above post. Just remember that the Arrangements tab shows you how your displays are arranged - and you can use that as a guide for how to move your mouse from one display to another.

OK, no worries. I'll try again and play around with things to see if I can get it to work.
