WiDi Adapters Let Notebooks Wirelessly Stream Blue-ray Content to HDTVs

WiDi (for Intel Wireless Display) is the latest technology that makes use of Wi-Fi to wirelessly move anything  on a notebook screen to an HDTV, that is if the notebook is powered by one of Intel’s latest processors, and the HDTV set has built-in WiDi support or is added by connecting a WiDi adapter to one of the TV’s inputs.

Although a number of products now support Internet streaming, WiDi makes streaming content from a notebook screen exceptionally easy. Users simply need to run Intel’s software on the notebook and no additional wiring is required.

Unfortunately, the technology is the proprietary rights of Intel. Users with laptops that do not have an Intel CPU will not be able to make use of this technology. The good news, however, is that the Wi-Fi Alliance is working on new technology that will match WiDi’s capabilities, and that the Alliance will be able to certify for interoperability between products from different vendors. This is still a couple of years from becoming reality though.

WiDi is not new technology. Intel first announced WiDi at the CES show in 2010, and Netgear introduced its first Push2TV WiDi adapter later in 2010. This year, Intel announced its second-generation version of this technology that improves on the first by supporting 1080p resolution.

In order to run the second-generation of WiDi, users require a laptop which runs on an Intel Core i3 / i5 / i7 processor and Intel HD Graphics.

This year, Netgear also announced their second-generation Push2TV, which supports the advanced features including 1080p video. The device is expected to be launched later this month and will retail at a price of $120. The device will be shipped with an HDMI cable and will also support composite video.

D-Link also announced its first product that will support this technology. The D-Link MainStage Adapter will connect to TV sets either via HDMI or component cables. Pricing has not been announced, and the MainStage is expected to be available by mid-year.
