WiDi, short for Wireless Display, is an Intel technology built into notebooks powered by Intel Core processors. WiDi 1.0 supports 720p video streaming over the air to the Netgear Push2TV adapter, which connects to TVs via HDMI. But with the release of more powerful second-generation Intel Core CPUs, Intel has released WiDi 2.0. This spec supports 1080p HD video at 30 fps and doesn’t suffer from nearly as much latency. Thanks to the new Extend Mode on the latest Netgear adapter, you can also browse the web on your laptop and wirelessly stream a movie to your TV at the same time.
Available Gear: The Toshiba Satellite E305 ($1,089; www.toshibadirect.com) is just one of many WiDi 2.0-capable notebooks available that work with the Netgear Push 2TV HD TV adapter ($120; www.netgear.com).
What’s next: Intel will be releasing an update to allow WiDi 2.0 laptops to stream DRM-protected content, including Blu-ray movies. The company is also working with TV manufacturers to build WiDi directly into TV sets and bypass WiDi adapters. Also in the works is a sound-only option for netbooks and notebooks with Intel chipsets that will stream music from a notebook to a WiDi adapter linked to a home sound system. Logitech has already announced an audio-only WiDi adapter that plugs into home systems via 3.5mm or RCA jacks, which will go on sale in May for $29.99.
