Mirroring or extending

Overview

In terms of what you see on it, your pen display is just another monitor/display to your computer. So, you can control how the computer shows its desktop to the pen display.

You have two options:

  • Extend the desktop - this means you can see different things on the pen display from your monitor. This is what I recommend you use.

  • Duplicate the desktop (aka "Mirror the desktop") - This means your pen display and monitor will try to show the same exact thing.

Considerations

Duplicating is very useful and intuitive but generally I think Extend is better choice for most people and situations.

Things that may happen with duplicate

  • Black bars on one of the screens. This happens if they don't have the same aspect ratio

  • If the two screens have different resolutions, the duplication may use the lower resolution.

  • If the two screen have different max refresh rates, the duplicate will use use lower refresh rate for both.

Alternative methods that effectively duplicate your canvas

If you just want to see your canvas on both displays, explore this option instead: Showing canvas on another display

Steps to control extend vs duplicate

  • Open Display Settings

  • The displays your computer is connected to will be shown and each one is numbered. The one in blue is the display currently selected.

    • If a display has two numbers, that means the desktop is being duplicated across those displays

  • NOTE: If you only see one display then the these settings do not apply.

  • Select the display that corresponds to your tablet

  • Towards the button right (to the right of the Identify button) you will see a dropdown setting that controls how the desktop is being applied to this display. Depending on how the display is already configured, the dropdown will say either

    • Extend desktop to this display

    • Duplicate desktop on X and Y

      • X and Y will be the numbers referring to the displays

  • Switch the dropdown between the Extend or Duplicate option as needed.
