Tips: There's two variants of WiDi. The first one generation came with 1st generation Core, and the second one, with 2nd generation Core. You'd want to check to see which version your Netgear adapter supports. Or you can tell us the model number of the Netgear device and we can tell you.
BTW, the 2nd Generation Core's WiDi is much better and that's the one you want to get. 3rd Generation Core is even better but the 2nd generation is the minimum you should get.
Some manufacturers may choose not to support WiDi despite meeting the requirements. Make sure that it does.
