Extending/Combining Displays

Mirroring a Display

To mirror the image of a display to another display, you don't need to use multi-display support. Just transfer the buffer received in the first display's Flush Callback to the other display as well.

Splitting an Image

You can create a larger virtual display from an array of smaller ones. You can create it by:

  1. setting the resolution of the displays to the large display's resolution;

  2. in Flush Callback, truncate and modify the area parameter for each display; and

  3. send the buffer's content to each real display with the truncated area.
