It is increasingly common to work with multi-monitor environments, when we are not attaching an ultrawide monitor to our equipment to maximize the viewing area. It is ultimately about this, gaining space to add more information before our eyes and here the mobile can become a key tool, since our smartphone can become a second screen for our tower or our laptop.

This is where we are going to offer you different alternatives in terms of applications that you can install on your Android that will allow you to connect with both Mac and Windows (not in all cases) to be able to work as if it was an external wireless display. In fact, it is, and you can do it with your tablet too. Let’s go.

Duet Display, no trial version

We start with a very popular iOS application which also has its corresponding version for Android. With Duet Display it is possible to connect the mobile and the computer to use our smartphone as a second screen, being able to choose between extending the desktop or using the mobile as a duplicate screen. We can connect the application to both Windows and MacOS with its corresponding desktop client and it turns out to be quite a simple and versatile application.

There is no trial period or free version here. The only thing that Duet Display offers us is to pay from the first hour (10.99 euros) so our recommendation is that you try it as soon as you buy it so that in case it does not work for you, you can request a refund as soon as possible. Duet Display doesn’t have a trial, so you’ll have to give it a try and if it doesn’t work for you, send the app back to Google and they’ll refund your money.


Splashtop Wired XDisplay, with 10-minute trial sessions

We continue with Splashtop Wired XDisplay, one of the most popular mirroring applications in the mobile ecosystem and also one of the most compatible, the one that accepts more models when it comes to operating it. We found it in the Google Play Store and we also have versions of the desktop client for Mac and Windows. It is easy to use because all you have to do is download the client for computers, enable USB debugging on your mobile from developer settings and connect both devices with a USB cable. From this moment, and as long as there are no incompatibilities, you will have the computer’s extended screen on the screen of your smartphone.

At Splashtop Wired XDisplay, we have a free version that lets us run it in 10-minute sessions, so we can check if it’s working as it should (or as we need it to) before facing payment. of the full version: a payment of 7.49 euros.

Spacedesk, free and only for Windows

We end, at least for now, with a third and final recommendation. This recommendation is none other than Spacedesk, an application that also allows us to extend the desktop from the laptop to the mobile as well as to use our smartphone as a duplicate screen. We left it for last because Spacedesk is not compatible with MacOS, so it will only work with Windows computers. A shortcoming which we hope will be resolved as soon as possible.

We are talking about a very good application that allows connection via WiFi by default, and which is slightly more unstable than the first two alternatives. Here we are in front of a free application without ads, and it seems that this will not change in the short term.
