Tutorial: Setting up Dual Display

Dual Display outputs a SuitePOS shopping cart in real-time to an external monitor or HD TV screen. Each line item, the quantities and running totals (including promotions and discounts) are displayed to the shopping.

Certain retail environments may require a dual display. This is typical where there can be a large number of items in a cart (eg. grocery store) or where local laws mandate it. eg. California.  California Legal Statute.
Input is NOT allowed on the 2nd display. In other words, it can not be used for signature purposes. As a further point, signature is no longer required for Square, Square Plus, PayPal and Stripe integrations. 

Step 1: Enable Dual Display

  1. Go to POS Settings.
  2. Enable Dual Display.
  3. Set the Idle Screen image (optional)

Step 2: Decide on the configuration option

  1. Order any HDMI capable TV or monitor
  2. OPTION 1, order an Apple TV
    1. Connect the Apple TV to the monitor and configure
    2. Use Apple Airplay (aka Screen Mirroring) to show the device to Apple TV (if you have a black border around the display, you may need to turn underscan "Off" in the Apple TV settings menu).
  3. OPTION 2, order the Apple Lightning Digital AV Adapter.
    1. Plug in the adapter to the device.
    2. Connect the adapter to the TV using a HDMI cable

Step 3: Perform a test

  1. Log in to SuitePOS.
  2. Perform a sync.
  3. In SuitePOS, run a test sale to ensure the cart is displayed on the dual monitor.
A HD "gaming monitor" between 9" and 11" is recommended. Ideally this monitor should have minimal branding or button exposure.


Most problems arise from loss of the Airplay connection and/or power/cabling issues.
  1. Check all wiring, connections and power.
  2. If using the Apple TV, check that Apple Airplay (aka Screen Mirroring) is working.
  3. If using the Apple TV, Reboot the Apple TV.
  4. Reboot the device and perform the above steps again.
