Did you know that you can wirelessly stream PC games to your television? Here's how it works

Can you connect a PC to your TV without wires? There's enough interesting display technologies around now that stream video directly from a graphics card onto a TV screen over the air, and when Alienware's new M18x appeared in the office armed with the latest version of Intel's Wireless Display technology (WiDi), we had to give it a go.

Although WiDi compresses the video signal and there's obvious artefacting around text edges, it's pretty smooth and simple to set up. Once that's done, you walk into the living room with your laptop, turn the TV on, and... er... that's it. WiDi even takes the audio feed with it, so you can listen through your TV speakers.

The only problem is that it's not quite there for gaming yet. As the photo above shows, there's just under half a second of lag between the laptop screen at the bottom and the TV, which is mirroring the display. That's no good.

Still, there's hope. I spoke to ASUS this morning and they reckon they'll have a Wavi kit for us to review in time for next issue. That, it's claimed, will give us a lag free feed direct from a PC up to 25m away onto our TV screens and back again, so the remote unit (by the TV) will also double up as a USB hub.

If it works, and that's a big if, it'll make consoles redundant.
