4K and 3-D Consumer Displays are Coming. Is This a Good Thing? 

 You may have noticed that there are several 3-D movies being advertised as coming to your theaters soon. They seem mostly to be animated films, or movies that have a lot of CG environments, but it won't be long before we get conventional movies that are shot in 3-D. This means the Blu-ray discs will have 3-D versions, and already there are some that come with red/blue glasses in the package so you can watch them in 3-D. A few new HDTVs have a port for a special device that transmits signals to polarized glasses, making the left eye and right eye lens alternating light and dark in synchrony with the movie. We obtained one of these HDTVs (rear projector), but have yet to see the 3-D device that is supposed to connect to it, so I can't complete the review.
