Screen Expansion – Laptop does not support video signal input, how to solve it?
There is a desktop computer, a laptop, and a display screen. I want to use the desktop computer as the host and the laptop as the secondary screen, but most laptops have HDMI output ports and do not support video signal input. How can I solve this problem?
Using Win+P to display the projection entrance of the computer, if the interface shows “Connect wireless monitor”, it means that the computer can expand the screen wirelessly. If both computers support this function, it can be achieved through this method
1. Desktop computer clicks to connect to wireless monitor
2. Notebook Projection Settings
3. After setting up, click on the link to activate the projection by searching for the laptop name in the list
4. After the projection is completed, there will be a connection prompt box
Note that when returning to the desktop, right-click and select Display Settings, you can configure the display of two screens (zoom, resolution, text orientation, etc.), as well as switch between primary and secondary screens:
