Have a single multi-interface graphics card? Or more graphics cards?

A single graphics card? Multiple interfaces? After connecting the monitor? Run the display detection function of the display control panel? Will n pictures of monitors or monitors be displayed after completion? Display modes are optional: copy (n monitors display the same content as the main screen) and expansion (one main screen, the other displays are expansion, and the mouse can continue to slide on the edge of the main screen to reach the auxiliary screen).

If the player allows multiple pictures to be played at the same time? Is there an option setting? Allow multiple instances? Drag the main screen directly to the secondary screen to play.
