"Assigning Video Outputs" Window

In this window, you can set some advanced options for the video card: mouse pointer type (software or hardware) and re-assign the video output of the card to different video surfaces.

In this window, you can reassign the video output of the card for the video surface.
You see a list of video surfaces here. To the right of each video surface, there is a column with all the video outputs of the card.
You can specify which video output you would like to assign to this video surface.
The video output currently assigned to the video surface is highlighted with a border and bold text of the checkbox label

Cloning displays allow you to display an image from one video surface to multiple monitors.
