Having enough screen real estate while working on laptops can be challenging, especially for those used to multiple monitor setups back in the office. Having a second monitor can be especially beneficial when working on laptops on the go. Owners of iPads and Android tablets have a cheap method at hand to turn those slates into wireless monitors for both Mac and Windows laptops.
The Air Display app is available for the iPad for $9.99, and the Android version costs the same. Both apps turn the appropriate tablet into a second monitor for Mac and Windows that connects to the laptop via Wi-Fi. Once the app is installed on the tablet, it directs you to the appropriate web site to download either the Mac or Windows app for the laptop.
After only a couple of minutes, the Air Display local service can be toggled on which initiates a search on the local Wi-Fi network for tablets running Air Display. The tablet running Air Display is selected from the search window and Air Display connects the laptop to the tablet.
The iPad or Android tablet is treated by either OS X or Windows 7 as an external monitor, with full OS control over the display. This allows user control over the location of the tablet in relation to the laptop. The tablet display can either mirror the laptop screen, or extend it to provide additional display space.
There is a slight lag due to the Wi-Fi connection, but it is so small to not be a factor. You probably won't be streaming video to the tablet due to this latency, but everything else works very well.
Air Display turns the tablet and laptop into a two monitor setup without compromise. It provides a second monitor for ten bucks, and that is an outstanding value. The benefits are fully realized when working in a hotel room at night as productively as back at the office with the two monitor configuration.
I use both the iPad and the Android versions of Air Display regularly, and have experienced no problems with either. The iPad with the Retina Display is especially impressive used as a second monitor with Air Display. Using this next to the MacBook or Windows PC shows without a doubt how superior the new iPad display is compared to that of the laptop.
Air Display permits rotating the iPad or Android tablet at will, and reconfigures the display on the fly. I find it particularly useful to put a document on the tablet in portrait for easy reference while working on the laptop.
I have tested Air Display for Android on both the Samsung Galaxy Tab 10.1 and the Transformer Prime without problems. Other Android tablets may not work as well according to the people behind Air Display.
