mouse not working between 2 monitors

Hello,
I'm trying to use my laptop as a second monitor for my PC. When I try to move the mouse from my main monitor to the laptop screen, it doesn't work. However, moving it the other way around (from the laptop to the main monitor) works fine.
Also, when I switch to the second HDMI input in the PC settings, it works, but on the first HDMI input, it doesn't.
Can you help me set up dual monitors correctly?

Hello there! I am Charity, I'm an Independent Advisor. I'm glad to help you today!

Thank you for the confirmation. Please right-click on your desktop and select "Display settings."​

In the display diagram at the top, ensure the monitors are positioned to reflect their physical arrangement. If your laptop is physically to the right of your main monitor, make sure its representation is also on the right. You can drag and drop the monitor icons to adjust their positions.​

Click "Apply" to save changes.

Please let me know if this works for you. I'll do my best to respond as soon as possible.

Kind Regards,
Charity
