Heres yet another option for wirelessly mirroring your computer screen to another display, but dont worry, this one rather impressive. Airtame, the creation of a group of Danish folks, is an HDMI dongle that links your PC — be it running on Windows, OS X or Linux — to whatever display its plugged into over WiFi. Installation is a breeze: all you need on the PC side is just the software, and from there you can choose which dongles to beam your screen to.
