How to use the free Splashtop Wired XDisplay app to turn your Android phone or tablet in a second screen for your Ockel PC

By Jesper — July 22nd, 2016

We’ve already written about using your iPhone or iPad as a screen for your Ockel. However, if you are an Android user, this new blog might turn out to be handy. Wouldn’t it be easy to use your Android smartphone or tablet as a screen for your Ockel? In this article we’ll explain you how to do this in the most convenient way with the Splashtop Wired XDisplay app.

Why would I need a dual monitor app?
The main reason why the Ockel team thinks it’s great to have a dual monitor app is because of the productivity increase. Two monitors simply make it easier to work in multiple windows and therefore boost your productivity. Whether you’re working in two or more spreadsheets, or writing a blog and surfing the web at the same time, there’s always a good reason to use a second monitor.

Another great feature of the free Splashtop Wired XDisplay application is that you do not need to use your PC-monitor. Just connect your smartphone or tablet USB-cable to your Ockel PC, start the application and you’re ready to use your phone or tablet as a monitor.

The (free!) App
There are many apps in Google Playstore for dual monitoring. We’ve tested a few of them and we believe the application called ‘Splashtop Wired XDisplay’, which is surprisingly a free application, offers the best and easy to use solution for both PC and Mac users. Since our Ockels are running on Windows 10, we’ve tested the PC-version of the Splashtop Application.

Wired XDisplay has a 3,5 out of 5-star rating in the Google Playstore. One small downside of this application is that there is some minor lag, which results in a less fluid user experience. However, for regular use this won’t be any problem.

The PC/Mac and Android application of Wired XDisplay is free, which definitely makes it worth to try out!

To set-up your Android smartphone or tablet as a second monitor you’ll need both the mobile and desktop application. We’ve written a short how-to install and setup the Wired XDisplay for your convenience.

How to enable Developer options in your Android device settings
|Wired XDisplay requires an activated setting which can be found in the Developer settings menu of your Android device. By default, this ‘Developer mode’ is hidden. Follow the steps below to active the Developer Mode and to select the required setting.
Enabling the developer settings is done in the same way for every Android smartphone or tablet. However, the location of the required option cannot always be found in the same place. You should navigate to the ‘Build number’ portion of the settings.

The different locations of ‘Build number’ – depending on your Android version
Here’s how to get to the ‘Build number’ option location:

Stock Android: Settings > About phone > Build number
Samsung Galaxy S5: Settings > About device > Build number
LG G3: Settings > About phone > Software information > Build number
HTC One (M8): Settings > About > Software information > More > Build number

Once you’ve found the ‘Build number’ option, tap seven times on this section. After two taps, a small pop up notification should appear notifying that you’re ‘X steps away from being a developer’. Keep tapping the ‘Build number’ option until the message: ‘You are now a developer!’ pops-up.
