Intel’s WiDi software does not support Macs, but it does support a specific list of WIndows 7 and 8 systems (see below for more details on compatibility). But if wireless streaming is something you must have, and if your laptop supports WiDi, you might consider Netgear’s product, which was the more reliable of the two-once I got it up and running. Unless you’re prepared for the possibility of arduous troubleshooting, I wouldn’t bother with either adapter. The Lenovo ThinkPad Helix Ultrabook that I used for testing required multiple reboots, driver updates, and reinstallations of Intel’s software. Pretty hard, as it turns out: Both devices proved enormously complicated to set up. Two fourth-gen adapters, Actiontec’s ScreenBeam Pro and Netgear’s Push2TV, are each smaller than a deck of cards, with just a couple of ports. Intel’s WiDi technology promises a lot: The third and fourth generations can wirelessly stream up to 1080p video, including copy-protected content such as commercially pressed Blu-ray movies, to a receiver embedded in an HDTV, a video projector, or some other display-or to a stand-alone receiver with an HDMI output that you plug into a display. ![]()
