Using your smartphone as a Windows or Mac secondary display: iDisplay

In an earlier blog post, I wrote about ways to use your old smartphone once you got a new one.  A reader asked that I expand on this post, so I am.

idisplay4One of my suggestions was to use it as a secondary display.  There are several apps out that will do this, for the iPhone/iPad and for Android.  The one I am writing about today is for iPhone/iPad/iPod touch.

Called iDisplay, this little gem does a terrific job at adding a second display to your Windows or Mac PC (because, you know, the Mac IS a PC.)

There are two parts to the setup: the iDisplay app for the phone and the desktop app that streams to the phone.  Installing on the phone is as easy as going to the App Store, searching for iDisplay, purchasing (it is .99) and downloading. Then, go to the iDisplay web site and download the appropriate desktop app and install that.  Please Note: it is also available on Android via the Google Play Store, but I am focusing on the iOS version here.

idisplay1Once running, the desktop server uses Bonjour and Wi-Fi to talk to the phone.  In Windows, it acts as a driver, allowing full video and audio as well as adding touch to a non-touch computer.  On my Windows 8 desktop that does not have touch, using this app on my iPhone adds touch.  And, works very, very well.

On my desktop, I let it use the default, which is to extend my display to the second device. The cool thing is that in the Windows 8 desktop, I get the full experience, task bar and right click action all work.  Apps that were running already, will remain on the primary display, apps that you start from the phone will display on the phone. I have to admit, I rather like seeing Windows on my iPhone.

idisplay3Among the features in the phone app are: gestures, integrated on screen keyboard, audio playback, touch, full interaction with your desktop.  From my desktop, I could even watch a video that was streaming from the desktop with relatively high frame rate. Of course, that will depend on your Wi-Fi network and how busy it is.  Also, the phone app works great with Windows 8 Start Page.  So far, it all seems to work nicely. One really nice feature is that the phone app can show you a list of currently running apps on the main display and allow you to move them to the secondary display, pretty nifty and useful. And for an application that has multiple windows or instances, you can select which one to view.

idisplay5I tried running the server app from my VivoTab Smart tablet running Windows 8.1 preview. It works, but only to a point.  I think it is a problem with the video driver and the Atom processor. It is slow and the only mode supported is mirror of the desktop, not very useful. And, really, for a tablet, you won’t need a second screen, but I had to try anyway.

Now, even though this app works very, very well, there are a couple of drawbacks.  One, it does put a load on your Wi-Fi network, so keep that in mind; two, using the Windows Desktop on an iPhone screen is a laborious task. The ‘chrome’, so to speak, is just too small. I had a difficult time closing windows or tapping on the address box to enter a URL. Now, you can zoom, which helps, but using full screen is pretty tough.  Using the extended mode on the phone app allows this.

Overall, I think this is a very well and highly useful application.  Not only is it a secondary display, but it also acts as a remote desktop as well.  Well worth the purchase price.

UPDATE:

I downloaded the Android version to my Kindle Fire. While I am still evaluating it, it looks just as good as the iOS version. Since the Kindle Fire is somewhat bigger than the iPhone, it is much easier to use Windows on the this device. It also works better with the system mouse. In addition, you can use USB to connect your Android device to the PC (or, presumably, your Mac.)  I have a Mac Mini, so I think I may try that as well. How about full Mac OS X on your Android or iPad?

One thought on “Using your smartphone as a Windows or Mac secondary display: iDisplay

  1. The problem with the desktop app is that it never and i repeat never automatically syncs stuff from ny phone to the pc, never. I always need to do it manually. That’s why i personally prefer the win8 app.
