Use Tablet as Monitor | What You Need to Do to Make It Work On Various Operating Systems

You might have had a look at your tablet as a secondary monitor. This article will guide you on using your Android, Windows, and iPad tablets as a secondary display. Do you have an android tablet? Are you debating whether or not to use your tablet as a secondary screen? Well, you can; let’s get our hands-on.


How to Use Tablet as A Second Monitor

Your android device allows you to connect to an external monitor in two ways, either using cables or a wireless connection. When there is a need for portability (see ‘Best Portable Monitor‘), users go for a wireless connection. Any smartphone can connect wirelessly through wi-fi.

However, connection via wi-fi has low stability, often resulting in a prolonged lag between what you display on the computer and what you see on your tablet monitor display. If your Wi-Fi is fast and reliable, it will be of less concern only if your devices have sufficient RAM to run your display quickly.

Not everyone will need to pair his monitors all the time, but it might improve productivity if you give it a try. You can make your tablet as a second monitor if you find it fruitful. You require a computer that supports Windows 10, Mac, Android device, and iDisplay, which you can download from the Google Play store.

Not only does iDisplay work on wi fi but it also supports USB cable users.

Installing iDisplay on the Tablet and Computer

On your android phone, installation of iDisplay from the play store is automatic. The setup process on Windows is similar to that of a Mac laptop. To start the process, double-click the downloaded driver file. A warning screen pops up; click Yes to install the software.

 Let iDisplay do the rest of the installation; it takes a few minutes, depending on the speed of your devices. After the iDisplay completes the installation, restart your computer.

 The driver installs automatically once your laptop restarts; confirm in the system for assurance. But you can install it by yourself by typing ‘iDisplay’ in the start menu.

Connect to Your Mobile Tablet or Phone

Launch the driver once the setup is running on your device, and it will look for the computer running its server. When the laptop finds the server to connect, a warning pops up on the desktop requesting whether to link with the device. Click “Always Allow” so the warning message won’t appear again.

Your monitor will appear flickering when the app is getting connected. Don’t worry about it, as a few minutes later, your mobile tablet will display what is on your laptop.

Adjust Your Display Settings on the Laptop

On your computer, right-click on the remote desktop; on the drop-down menu that appears, choose the Display Settings. Apply multiple displays and decide whether to make your mobile phone the main second display.

Disconnecting the wired devices when you finish using your tablet as a secondary screen is more manageable. In the bottom right corner, tap the green action button, and a drop-down menu appears on the left-hand side. Select the Disconnect option, the screen will flicker again, and the server disconnects.
