Toshiba working on a 3D TV that doesn't require glasses, and this could be a game changer for 3D technology, if it works. However, some folks think that Quad HD/4K could be the next big thing in HDTVs. And -- who knows? -- it might filter over into Macs.

As noted by "ZDNet" (http://macosg.me/2/sn), Quad HD/4K provides more than four times the resolution of 1080p HD at 3840 x 2160 (slightly less than the 4K digital cinema standard, but way more than the 1920 x 1080 of today's HDTVs). While it will require its own set of infrastructure updates (new TVs, additional bandwidth to get the content into your home, etc.), it won’t require any pair of glasses on the end user’s face.

In August Marseille Networks demoed its its complete, end to end 4K-over-HDMI prototyping system, stimulating the rapid adoption of Quad-HD resolution in Blu-ray and audio video receivers (AVRs) for the next wave of high definition TVs. Amine Chabane, CEO of Marseille Networks, says Quad HD offers four times the resolution of HDTV.

Higher resolutions will allow for a true digital cinema experience in the home. Many AVRs and Blue Ray devices and next generation TVs will be moving to 4K resolution and much of today’s content -- from photos to movies -- are already captured in 4K.

Maybe I'd better start saving for a 3D Quad HD (you know they're coming). And perhaps a 30-inch (or bigger) 3D Quad HD Mac. How cool would that be?
