TV Anarchy: Passive 3-D Available at Home

| By | Reply More

The next round of cutting-edge home television technology is here. LG has released their 2012 Cinema 3-D line of LED televisions featuring passive 3-D technology. The biggest selling point for consumers are the passive glasses used for 3-D viewing.

When you go to see a 3-D film like the Michael Bay Transformers franchise or James Cameron’s “Avatar” at the movie theater the glasses given to you are passive 3-D technology. They’re simple and lightweight and can be reused at home if you have a passive 3-D television.

Most televisions are active 3-D, meaning you have to wear glasses with shutters that rapidly alternate which eye is viewing the television. These glasses communicate with the television via an infrared signal so the image delivery is correctly synced. The glasses aren’t universal, require batteries to operate and are heavy- especially if you wear prescription glasses. Most active 3-D televisions only come with a pair of glasses and additional glasses cost around $150 per pair. Active 3-D takes a lot of commitment from the user to be successful and perhaps that’s why it hasn’t been very prevalent in American homes.

Passive technology, on the other hand, relies on the television to broadcast images for the left and right eye simultaneously but polarized differently. The lightweight, inexpensive, battery-free, polarized glasses show each eye only the images intended for it. Technically, you’re not getting the full resolution of the television for each eye but the overall image your brain creates should be just fine.

Passive 3-D technology for home use has been poor at best, until LG rolled out their 2012 lineup. The LM6700 series of television sets gets a 3.75/5 star rating from the expert(s) at PC world Australia and a 4.5/5 star rating from their users. Caleb Denison of Digital Trends said of the 3-D viewing experience, “we found the picture to appear remarkably deep. Watching Cloudy with a Chance of Meatballs on this set was an entirely new experience. The images were stunning to behold, not to mention the passive 3-D was totally free of flicker and crosstalk.”

LG provides 6 pairs of the passive glasses with the television, so it’s easy to get a whole group together to watch your favorite 3-D action flicks from Michael Bay, James Cameron, or Disney/Pixar. You’ll be the most popular house on the block with comfortable glasses that won’t break down in the middle of a movie marathon and don’t have your guests worried about replacement costs. Don’t wait until the new Teenage Mutant Ninja Turtle movie gets released on 3-D blu-ray to pick up a 3-D television. The technology is available, affordable and usable.

The biggest drawback with the LG LM6700 line is the overly ambitious Magic Motion remote which looks like something straight out of a Michael Bay film. While the manufacturers had the right idea in basically crossing a traditional television remote with a Wiimote for point and click functionality, every movement of the remote leads to a cursor appearing on screen. Furthermore, the remove is unstable and topples over on flat surfaces. A universal remote can be programmed to control the television, so all of these drawbacks can be mitigated with a little time and small extra investment.
