Movie theaters could screw up your 2D movies by leaving the digital projector set up for 3D

We generally prefer to do our movie viewing in our own home theaters, but when we succumb to the temptation of public moviehouses we often choose digital projection hoping for a flawless viewing experience. Unfortunately, this report by The Boston Globe indicates that may not be the case. It is alleged by unnamed theater employees that theaters are leaving the 3D lens adapters on their Sony 4K digital projectors even when showing 2D. Just like viewing 3D, this cuts the light output and it's worse for 2D films not made with that in mind, but theaters do it because removing the lenses is overly complex and many moviegoers don't seem to notice or complain. The Globe suggests checking the digital projector yourself -- if you see two beams of light from on high at a 2D flick then something is rotten in Denmark. Check the article at the source link for a rundown of many of the chains using these types of projectors and why that's the case (money), but after this and Liemax premium VOD is starting to sound better and better.
