I recently bought a 17″ Dell laptop and didn’t find out until yesterday about a little feature it has – and most recent PCs and laptops have – called Miracast. The 50″ 4K SUHD Samsung TV I bought in an irresistible deal last week also supports it, as do most new Smart TVs. To use it in Windows 10, you simply click the Connect button in the Notification Center, then on the TV that shows up on the network listing – that’s it. Miracast is essentially HDMI-over-WiFi projecting (Intel’s version is called WiDi), and it’s so good that I’d advise selling any projector manufacturer stock you own. To wit:
My Samsung phone also supports screen mirroring, so I can display its screen live on the new TV as well.
For fixed setting projection needs, I don’t see why anyone should ever again shell out US$700 or $800 for a projector – that was the price last time my company bought one six years ago – when one can spend the same amount and get a 50″ TV with 3840 x 2160 resolution, triple that of a typical projector, or spend a hundred or two more for a 60″ version. The quality is several tons better than projecting on a white screen, the speed is fine on 802.11n wireless, and you don’t even have to turn the lights off.
