How to Use Your Tablet As Monitor

Well having a second monitor apart from your PC is advantageous because it will provide you more space to work on.  But, setting up another screen can be really tiresome or expensive and not all operating system actually supports this dual display. In today’s time, where interconnectivity between devices is actually a thing, sending your computer to your phone is now also possible. Thus, you’ll be able to control your computer screen without even moving your mouse and typing on your keyboard. Furthermore, you can also remotely keep track of your computer’s activity. Scroll down in order to know the different applications that you may use. Let’s now discuss How to Use Your Tablet As Monitor. Let’s start!

It’s no secret that two monitors can also improve your productivity, however, not everyone needs a pair of screens all the time right. If you guys find yourself in a situation where a second screen could be beneficial, but, you can easily make your Android device serve double duty as well.

Now, before we get into how, I first want to point out that. Actually, it makes the most sense to use an Android tablet as a second monitor, this will also work along with phones. If you guys just really, really have to get a tiny bit of information from off of your main screen. Then go ahead and give it a shot with the small screen as well. However, really, a tablet is best.

How to Use Your Tablet As Monitor

Android smartphones and tablets are really versatile in terms of features, you can also mirror your Android to another Android and as well as a PC. In general, you guys have to install a second monitor app on your Android and install the app’s client app on your PC. When you do that, then you can connect your Android to your PC, using a USB cable or WiFi. (When both of the devices are connected to the same network) and that’s just it.


Spacedesk is a famous choice in order to transform your Android into a second display monitor for Windows PC. You can also connect your PC and Android through USB, Wi-Fi, or LAN. The resolution is pretty decent and you get touch support as well.

To start this, you need to install the important drivers on your Windows PC. The app is also available for Windows 7 and above. Opening the app will automatically detect and display all of the PCs on the same server that has the drivers installed. Simply click on it to connect. Open the app on your Android and then connect to your PC. The app should detect the IP address and also the name of your system.

In order to use your tablet or Android as an extended display, you just have to configure secondary display options in Windows actually. In order to do that go to the Control Panel and then Display Settings. Choose Extend These Displays and tap OK. You should now be able to use your Android as an extended display as well.

Spacedesk basically works well if you do not want your phone to be bounded via a USB. But that’s the only complaint I have. Because it works wirelessly, there is also a noticeable amount of lag. It’s pretty good that you can switch to hotspot and USB as well.

iDisplay | tablet as monitor

iDisplay is also another display mirroring app on this list. iDisplay started with the macOS and iOS however, quickly expanded to other Operating systems as well. You also have apps for Windows and Android that makes it a really good cross-platform solution. It also supports 60 fps and plus offers multi-touch on the device you are using it on.

iDisplay has everything that all the other app offer, along with one caveat. USB support is actually not available for Android yet. It does support WiFi though and also comes along with multi-touch support.

Supported Medium: LAN, Wi-Fi, USB (except Android)

Google Remote Desktop

Just like Remote Desktop for Windows, it also permits you to control your PC through your Android device. You can also run commands on your computer from your Android phone. Basically, each and everything that you can do on your desktop can also be done from the Android phone as well. Remote Desktop, just like all Google products, is easy to use and simple order to set up. You guys just need to have a working Gmail account. The ability to control your PC remotely is where it actually shines the most though.

Google Remote Desktop works seamlessly however, you cannot use separate apps on both of the screens. It does not let you use your phone as an extended display actually.

Air Display 2

Air Display 2 actually works the same way for Mac the way Spacedesk does for Windows PC. However, it comes with a price of 14.99$. It basically turns your Android device into a secondary screen for your Macbooks. You can extend mirroring the screen to more than 4 secondary devices. On top of that, it also supports full HD displays too.

It also supports all the way back to Mac OS X 10.8 or Lion. You guys can also use your PC as a secondary screen for your Mac. However, it does not work the other way round like you cannot use Mac or any mobile device as a secondary screen for Windows actually. I read the FAQs section and it also says they are working on a solution, however, it also says that they are not “close enough” to give an ETA.

On the plus side, it also offers a more responsive experience thanks to the dynamic compression algorithm the team is actually using. It also supports retina display, something that is basically missing in Spacedesk. App also features Air Stylus that you guys can actually use the secondary device in order to draw designs on directly.

Air Display works seamlessly however, the issue is the pricing model. With each and every major upgrade Avatron Software i.e. the creator of Air Display increases the price actually. This is something that actually bothers long-time users like me however, hey if money is not a problem then you are actually good to go. Another thing that bugs me is that you have to install Air Display Host on your iPhones, Androids, and PCs that you want to use as a secondary screen. However, Air Display can only be installed on Macs. So the cross-platform compatibility gets a little limited as well.

Duet Display

This was originally the go-to for Mac and iPad users actually, however, because Apple has added native support using Sidecar. Duet Display has expanded in order to support Android and PC as well. However, the iOS version remains more robust, which offers a bunch of features and backward compatibility that Sidecar does not. The Android version also performs pretty well. There’s by no means a 100% success rate along with each and every tablet and computer. However, current feedback seems to suggest your chances along with Duet are pretty good.

Duet Display basically invited us to beta test their new app, and it actually worked really fine on my Google Pixel and Windows 10. Although, I did encounter a few bugs like connection breaks. Also, while you guys can connect your Android Smartphone wirelessly to a Windows PC. You still have to attach a USB cable if you guys want to use the Android app along with macOS.

The app is competitively priced at $9.99 and also offers a lot of features and supports a really wide range of devices. You can also get the app for both Android and iOS devices actually.

Splashtop Wired XDisplay | tablet as monitor

Well, this is another multi-platform solution that’s been getting really good feedback. It works just like the rest – downloads drivers onto your PC, the app onto your tablet or phone, and you guys are off to the races. Splashtop Wired even supports Kindle actually. Perhaps the biggest selling point is the ability to support more than 1080p at 60fps. But, there is actually a caveat. As the name suggests, there’s no Wi-Fi option and this app also needs a USB connection. If that’s not an issue, then Splashtop Wired may be your best bet. This is not to be confused along with the company’s marquee offering, also a remote access application named Splashtop Remote.


Splashtop Wired XDisplay, just like the name suggests, will need you to have a USB handy. Unlike Spacedesk, WiredXDisplay permits you to connect your phone only through USB. On the plus side, because you are connected through a wired medium, you get better resolution and frame rate as well. It supports Full HD resolution at 60 frames per second actually.

Wired XDisplay can be installed on both Mac and PC, which gives it an edge over Air Display. Mobile apps are also available for both Android and iOS. Splashtop uses USB over WiFi for just one simple reason, it basically offers a more responsive and real-time experience. There is also no lag whatsoever and you get a battery saver mode which drops the frame rate and resolution in order to save up on processing.

Supported Medium: USB

Adjust Your Display Settings

From here, you guys can tweak and adjust it the same way you would any other monitor. Just right-click on the desktop and then just select “Display Settings.”

Again, relying on what version of the Window you are using, this may look different than my screenshots—the concept, but, is still the same. You can also treat your new mobile display as anything hard-wired. .You guys can move it from right to left, top to bottom; choose in order to extend it. Or even make it the main display as well. I can’t imagine why you’d want to do that, however, hey—you can.

When you guys are finished doing that, disconnecting the display is just as easy as connecting it as well. First, click on the green action button in the bottom right corner. (You guys have to tap it—this can’t be clicked with the computer’s mouse). This will then open the menu on the left side, where you guys can choose “Disconnect.” When you click on that, your computer screen will then flicker once again. When the server disconnects and everything will go back to normal again.

There are also a handful of other useful options in this menu, such as the option to show the on-screen keyboard. Even more useful, but, is probably the “Show window” option, which provides you a full list of all the currently-running software on the PC, then automatically pulls it to the device. You can also start applications in the taskbar with the “Start Application.”

Finally, there are some things worth noting in the Settings menu. They’re mostly self-explanatory, however, definitely something that you should take a look at if you guys want to make the most out of your second screen. Definitely check out the Resolution option–relying on the resolution of your tablet. You may want to tweak this option so that windows and icons do not show up all tiny actually.
