A completely wireless solution, Air Display takes advantage of OS X Lion and Mountain Lion HIDPI display mode to turn the new iPad’s 2048×1536 display into an ultra-crisp 1024×768 retina display. Setting up Air Display to turn that new iPad into an external retina display for a Mac is a piece of cake, be sure to meet the requirements and get started.</p> <p><strong>Requirements</strong></p> <ul> <li><a href="http://click.linksynergy.com/fs-bin/stat?id=uO47tEUahH8&offerid=146261&type=3&subid=0&tmpid=1826&RD_PARM1=http%253A%252F%252Fitunes.apple.com%252Fus%252Fapp%252Fair-display%252Fid368158927%253Fmt%253D8%2526uo%253D4%2526partnerId%253D30" target="itunes_store">Buy Air Display for $9.99</a> (App Store link)</li> <li><a href="http://avatron.com/apps/air-display/download/mac">Download and install AirDisplay Connect for free</a> on the Mac (Windows version available) and reboot the computer</li> <li>OS X Lion or OS X Mountain Lion to use HIDPI mode</li> </ul> <p>The 15″ MacBook Pro (late 2008 and mid 2009) and 17″ MacBook Pro (early and mid 2009) are not supported due to their video cards. Other Macs should work fine, though there are some limitations with older hardware which you can read more about below.</p> <h2 style="font-size:1.3em;">Setting Up Air Display as an External HIDPI Mac Screen</h2> <ol> <li>Launch Air Display on the iPad</li> <li>On the Mac, pull down from the AirDisplay menu item to activate the app, then select “iPad” from the devices list</li> <li>Wait a second or two while the screens flicker blue and for Air Display to sync the Mac and iPad</li> <li>After the iPad is found and displaying a Mac desktop, open Display Preferences to configure the display arrangement and to set the display as HIDPI (1024×768)</li> </ol> <p><img src="http://osxdaily.com/wp-content/uploads/2012/04/air-display-mac.jpg" alt="Air Display preferences in Mac OS X" title="air-display-mac" width="620" height="412" class="aligncenter size-full wp-image-29057" /></p> <p>The iPad is now an amazingly crisp external display for the Mac. Drag windows over to the iPad to see just how gorgeous things are and to get a preview for what future Mac displays may look like, it really has to be seen to be believed just how nice it looks. When in HIDPI mode, the displays resolution is 1024×768 but displays extraordinarily sharp HIDPI assets and images.</p> <p><img src="http://osxdaily.com/wp-content/uploads/2012/04/retina-assets-mac.jpg" alt="Retina assets in Mac OS X" title="retina-assets-mac" width="620" height="457" class="aligncenter size-full wp-image-29058" /></p> <p>Air Display respects the iPads screen orientation, allowing you to use the iPad as a screen in either horizontal or vertical mode. You may want to use <a href="http://osxdaily.com/2011/03/09/ipad-orientation-lock-ios-4-3/">orientation lock</a> to prevent the screen from rearranging itself and flickering as you move it around during initial configuration.</p> <p>This is a really nice app that comes highly recommended, but it won’t be a perfect solution for everyone and as I mentioned above there are some limitations. Less powerful Macs will be taxed hard by outputting to the external retina display and this makes the app not particularly practical on older hardware. In our testing, Air Display runs wonderfully on newer MacBook Pro, MacBook Air, and iMac models, but struggles on a 2010 MacBook Air where it consumed a constant 45% of CPU and spiked up to 90% CPU use when moving windows around the iPad screen. For this reason, I wouldn’t necessarily recommend Air Display for older or less powerful Macs, and Avatron would benefit from offering a limited 10 minute free trial version much <a href="http://osxdaily.com/2012/03/01/mirror-an-iphone-or-ipad-screen-to-a-mac-through-airplay-with-reflection/">like Reflection app</a> so users can discover full compatibility before springing for the purchase. Another thing to keep in mind is that assets which aren’t optimized for the HIDPI display can look strange or display incorrectly because very few Mac apps and even parts of OS X just aren’t built for the HIDPI display yet, though this is no fault of Air Displays. Air Display also brings touch support to OS X, but you will quickly discover it’s a clunky experience due to Mac OS X not being designed for touch-based input. Turning a Mac into a touch device is a nice addition to the app, but it’s more fun than useful. </p> <p>All in all this is a quality iOS app, and if you have an iPad 3 that goes unused during the day while you work on a Mac, get Air Display and turn that iPad into an amazingly crisp external monitor. It’s a great app and well worth the $9.99.</p> </div> <p><a href="http://feedads.g.doubleclick.net/~a/8KbJI0zM7HE98MpwuADNVlibyzA/0/da"><img src="http://feedads.g.doubleclick.net/~a/8KbJI0zM7HE98MpwuADNVlibyzA/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/8KbJI0zM7HE98MpwuADNVlibyzA/1/da"><img src="http://feedads.g.doubleclick.net/~a/8KbJI0zM7HE98MpwuADNVlibyzA/1/di" border="0" ismap="true"></img></a></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=oFFOWR8CFmk:mEEPgfN4CoE:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=oFFOWR8CFmk:mEEPgfN4CoE:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=oFFOWR8CFmk:mEEPgfN4CoE:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=oFFOWR8CFmk:mEEPgfN4CoE:D7DqB2pKExk"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=oFFOWR8CFmk:mEEPgfN4CoE:D7DqB2pKExk" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=oFFOWR8CFmk:mEEPgfN4CoE:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=7Q72WNTAKBA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=oFFOWR8CFmk:mEEPgfN4CoE:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=qj6IDK7rITs" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/osxdaily/~4/oFFOWR8CFmk" height="1" width="1"/> View the full article
