Connect two monitors before using dual-screen expansion. At present, most graphics cards have dual interfaces, usually VGA and DVI in the early days. At present, most of them are dual DVI, and some even use HDMI.

Click the right mouse button under the desktop to connect two monitors, and then click the right mouse button on the desktop to select Properties-Settings. At this time, common menus such as adjusting resolution will appear.

There are "1" and "2" on the screen extending the desktop to this monitor. After selecting 2, check "Extend the Windows Desktop to this monitor" to set it according to the resolution of another monitor, and then click "Apply".

If you don't know which monitor is "1" or "2", you can select the "identify" button, and you can know the corresponding number of your monitor through system identification.

After selecting the application, you can expand the use.

Drag the mouse directly to the right to the next monitor. After the expansion is successful, the mouse can move horizontally to the desktop of another monitor, and it can work.
