Extended Display
Mirror Display
If you are a designer or illustrator, you can use this mode to see the effect while working.
1)Extended mode can output two different screens and mirror mode can output two identical screens. Note: If your graphics card has a splicing screen function, you can use the splicing screen mode.
2) The requirement for this KVM to achieve a dual-screen display is that each PC you connect to has the capability to support a dual or multi-screen display. This has nothing to do with KVM.
