The Tablet / iPad is an enormously useful little computer but when you’re sitting at your desktop or laptop you can’t easily use it in tandem with the larger computer.Rather than let it be lying unused when you’re at your main computer, use it to extend your desktop. Whether you’re extending your laptop monitor for an instant second screen at the coffee shop or using it to park your Photoshop palettes while working at your desktop, it could be best for parking IM windows, application interfaces, and other small but useful widgets and gadgets that you’d like to keep an eye on but don’t want to clutter up your main screen with.I have seen engineers, musicians, designers, and artists to use multiple display to get a bigger view of different windows which also increases their productivity.

An engineer needs bigger screen space to perform multiple tasks running at a time in different softwares such as 3D Modeling software like Solid Works, CATIA, and 2d drafting software like AutoCAD and Inventor.Similarly a programmer, designer, artist and a musician also needs bigger screen space to run their multiple software at a time and to keep an eye on all the processes without much time lag.So using a Tablet / iPad or even a Android smart phone with bigger screen could be very helpful for engineers, musicians, designers, and artists.You can use these software to share spreadsheet or slide show in a meeting.Create something and share it with your audience. If you’re a teacher, invite your students to join you for a beautiful demo. If you’re on a meeting, share that spreadsheet with your partners. If you’re having friends at your place, share family vacation photos.

Which Software should I use to extend our Desktop display to an Android phone/ Tablet or an iPad/iPhone?

There are numerous software available to extend your desktop to an iDevice or an Android device.Most of them are paid but some of them are free as well which works perfectly fine.They all have there own compatibility and limitations. Among the paid one the Duet DisplayiDisplay, and Air Display are quite famous.But here I would be using the AirScreen free App to extend my display from a Windows PC to an Android device.

Here is the easiest setup of AirScreen to extend the display to your Tablet or Smart Phone

All of these secondary display software comes with a Server and a client. A server needs to be installed on Windows PC or Mac and the client software should be installed on your Android or iOS.They must be running for the display to be extended.

In order for Air Duet Screen to work, your computer and Android device must be connected to the same Wi-Fi network.

Alternative to AirScreen- Secondary Display App

Now there is a limitation of AirScreen that it is not available for Mac or iOS so another Similar App like Duet Display and iDisplay could be the best alternative but I am afraid that these two are paid Software.They have their Secondary display Server Software free for the Mac / Windows whereas the Client display software are Paid.

Duet Display was the first app of its kind that allows you to use your iDevices as an extra display for your Mac using the Lightning or 30-pin cable.Duet display became very famous as it works on Lightning or 30-pin cable which reduces performance lag/ time Lag as compared to the wireless technology used to extend display.It allows you to use your iPad or iPhone as an extra display but isn’t available for Android. It was developed by a team of ex-Apple engineers for the purpose of increasing productivity for engineers, musicians, designers, and artists.

Its very easy to setup,you need to download a Duet Display server on Windows / Mac which is free.And then download the Duet Display Client on your iPhone / iPad which cost you $9.99.And then just open the Duet Display App on your Mac or PC (for free) and on iOS. Connect your iDevice to your Mac using a lightning or 30 pin cable. It’sDone.After you install Duet Display, you can just drag windows off the side of your display.
