Beam your Laptop/PC to your TV Wirelessly
Microsoft has announced a new wireless dongle to help PC users see apps, photos, and videos on their television screens, called the Microsoft Wireless Display Adapter.
For a task with so many practical applications — mirroring a PC’s screen onto a TV — actually connecting those two devices has always been more complicated than it should be. The most basic version is to tether a laptop or desktop directly to the TV via an HDMI cable, but that often requires the PC to be within a few feet of the TV, depending on how long your HDMI cable is. Other solutions, such as Intel’s Wireless Display technology are built into many Windows PCs by default, but require a hard-to-find proprietary receiver box, and a less-than-intuitive setup process.
The Microsoft Wireless Display Adapter looks and feels a lot like Google’s Chromecast, in that it’s a small stick with an HDMI output plug, connected to a second wire with a USB plug for power (intended for a powered USB port on your TV).
