Maximum PC: Television makers and the entertainment industry as a whole has been trying to cram 3D viewing down our collective throats (or eye sockets, as it were -- apologies for the unpleasant visuals), but having to don a pair of sometimes goofy looking goggles hasn't proven popular. The other problem with 3D TVs is that they're often limited to strict viewing angles. Sit just a little bit off axis and the 3D effect goes out the window. It doesn't have to be that way, as Dolby demonstrated at its booth at the Consumer Electronics Show in Las Vegas. Yep, THAT Dolby, the one that's known for sound.
