8 Solutions to Fix Duet Display Issues

Duet Display is an excellent service that allows you to use your phones, tablets, and laptops as a second screen for your primary PC or Mac. However, there may be times when Duet Display doesn't work or fails to launch, leaving you frustrated. In this article, we will explore eight different solutions to fix Duet Display issues and get it up and running smoothly. Let's get started!

1. Check the USB Connection

If you are connecting your devices using a USB cable, here are a few things you can check:

  1. Avoid connecting the USB cable to a USB adapter. Instead, connect it directly to the port of your Mac or PC.
  2. Try changing the USB port on your computer.
  3. Ensure that the USB cable you are using can transfer data and is not solely meant for charging.

2. Update USB Drivers

If you have tried different ports and cables but still can't fix the issue, try updating the USB drivers on your system.

On Windows:

  1. Press the Windows key, search for the Device Manager app, and open it.
  2. Click on “Universal Serial Bus controllers,” right-click on the USB drivers, and select “Update driver.”
  3. Choose the “Search automatically for drivers” option and install any suggested drivers.

On Mac:

  1. Open the System Settings app by clicking on the Apple icon at the top left corner.
  2. Select “General > Software update” to check for and install any available updates.

3. Check the Internet Connection

If you are using Duet Display wirelessly via Duet Air, ensure that you have a stable internet connection. It is recommended to use a 5GHz Wi-Fi connection for better connectivity and experience. You can check your Wi-Fi frequency on Windows, Mac, Android, and iOS devices.

4. Use the Same Duet Account on Both Devices

Make sure that you are using the same Duet account on both your primary and secondary devices. Open the Duet app on each device and check the account details. If you are using different accounts, log out from one device and log in again with the same account used on the other device.

5. Verify Your Subscription Plan

Check your subscription plan to ensure that it is active and not expired. Open the Duet app on your computer, select “Settings,” and click on “Manage Account” to view your current subscription plan and end date.

6. Change the Display Mode on System Settings

If Duet gets stuck while launching, try changing the display mode on your system settings. For Windows users, press Windows + P and switch between “Extended” and “Duplicate” modes. On Mac, open System Settings, go to Displays, and change the mode from “Extended” to “Mirror” or vice versa.

7. Force Quit the App and Reopen It

Force quitting the app can help resolve any lingering issues. On Mac, click on the Apple icon and select “Force Quit” or press Option + Command + Escape. On Windows, open the Task Manager and end the Duet app process. On Android and iOS devices, force stop the app from the app settings.

8. Update the Duet Display App

Ensure that you have the latest version of the Duet app installed. On Mac and Windows, enable the “Auto Update App” option in the Duet app settings. On Android and iOS devices, check for updates in the respective app stores.

By following these solutions, you should be able to resolve most Duet Display issues. If the problem persists, consider reinstalling the app or exploring alternative options. Remember to keep your app and system updated for the best experience.
