Many people who’ve had a new laptop in the last year will have experienced the frustration of showing up in a meeting room, only to find that you have no means of projecting onto the screen – there are at least 5 different types of connector that could go into the laptop, and 2 or 3 that might be supported by the screen in the room.
Wireless projection has been promised for years, with a series of proprietary and clunky technologies that never really took off. All this is set to change, using a technology which started as a consumer function on high-end TVs, yet is filtering down to £200 tellies and will be mainstream on projection systems going forward. Maybe. For now, we have to live with a profusion of dongles while projecting at work, but what about in the home? Ever fancied delivering a PPT presentation to the gathered family?
“Miracast” is a standard which allows devices – PCs and Android tablets, mainly (Apple does not support Miracast, preferring their own proprietary technology) – to replicate their display and sounds onto a remote device. Windows 8.1 now supports Miracast, and if your home TV is new, then you might well find it enables the screen mirroring technology too.
There are third-party Miracast devices which can bring wireless access to your “legacy” TV and sound system, potentially – EZCast HDMI WiFi adapters or the Netgear PTV3000. Maybe it’s worth treating your living room to some remote projection goodness?
A few things to check:
- You can only use Miracast over WiFi – it’s not applicable using wired connections, and some WiFi networks won’t support it either.
- Even if you’ve got an appropriate telly and a Windows 8.1 machine with the right kind of WiFi adapter, you may still need to get an updated display driver (either from your PC manufacturer or from Intel directly).
Surface RT currently does not support Miracast even though the Nvidia Tegra 3 SoC that powers the original Surface, does. Surface Pro and 2 should be OK.- You’ll need to add the TV to your PC, akin to pairing a Bluetooth device – a one-off process that is pretty self-explanatory, though if it doesn’t go smoothly, return to the “update your driver” section.
- As you may see, this is still not exactly Plug & Play…
Having said that, when it works – it works well. Think of Miracast as like HDMI over WiFi, so could be a way of streaming music to a TV connected to a sound system. Hello Xbox Music Pass, bye-bye Sonos?
