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 :ref:flush_callback to the other display as well.

.. _display_split_image:

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 :ref: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.
