‘Duet Display’ Download Now Live, Turns iPad into Extra Touchscreen Display


Earlier this week we told you about Duet Display, a new app made by ex-Apple engineers which allows you to turn your iPhone or iPad into an extra display for your Mac, lag-free thanks to the Lightning/30pin cable USB connection, with up to 60Hz refresh rates. The app is now available in the App Store for $9.99.

If you need extra screen space, this app will take full advantage of your iPad or iPhone to help you increase productivity with its simple plug and play solution. Duet Display also cleverly takes advantage of your iOS device’s touch capabilities as well, instead of just mirroring the display like some other apps.

Duet Display works on the following:

  • All iPhones with iOS 5.1.1 and later
  • All iPads with iOS 5.1.1 and later
  • All Macs with 10.9 (Mavericks) and later

Click here to download Duet Display in the App Store—it’s $9.99.

    If only the 12″ iPad will support on screen drawing capability , could be Apples version of a Cintiq to interact with desktop art programs.

    Anything come up about Apple VR glasses recently?

    Downloading now… Can’t wait to try when I get home. This is handy for me.

    Disappointment that the release version does not work with first generation iPad and iOS 5.1.1 as originally promoted. So much for opportunity to put old iPads to use.

  • I picked this up yesterday and it’s been working well overall. The response time is impressive and I find it more convenient to use than Air Display, which relies on a WiFi connection (Duet Display uses your iOS device’s cable).

    CPU usage can be quite high, especially if you’re using the top quality settings. You can adjust the Resolution and Frame Rate in the Duet menu bar app to take some load off the processor. I’ve read that they’re looking at ways to reduce CPU usage.

    As noted in their FAQ, it’s necessary to restart your Mac if you get the “Trust this Computer” message after reconnecting your iPad/iPhone. I was able to resolve this issue by opening the Settings app on my iPad and choosing General > Reset > Reset Location & Privacy. I clicked Trust after connecting the iPad to my computer and haven’t seen this prompt on subsequent connections, meaning that I no longer need to restart my Mac to continue using Duet Display.

  • Thanks for sharing Tim!

    It works with my iPhone 6+ on a MBP Retina, haven’t tried on the iPad yet.
