Samsung delivers precautions to viewers who may be photosensitive, pregnant, tipsy, prone to seizures and more.

People are gaga over 3D TV these days, but it may not be all fun and games for everyone. Display manufacturer Samsung, which recently began shipping its new 3D HDTVs, has posted a medical warning on its website, “Viewing TV Using the 3D Function” (PDF link) to read before you or your child watch 3D.

According to the safety information, for example, “Pregnant women, the elderly, sufferers of serious medical conditions, those who are sleep deprived or under the influence of alcohol should avoid utilising the unit’s 3D functionality.” So you may not want to fill your eyes with that double vision and 3D vision, to paraphrase Foreigner.

The initial warning from Samsung states: “Children and teenagers may be more susceptible to health issues associated with viewing in 3D and should be closely supervised when viewing these images.”

If you’ve ever been through a 3D demonstration, it’s easy to see why Samsung (and presumably other manufacturers that may post similar warnings) wants to ensure it has covered its bases and offered such safety information. Slipping on 3D glasses, plus the initial vision immediately after taking them off, can be rather uncomfortable or headache-inducing if you’re not used to it. I know a demo from Mitsubishi a couple of years ago, while very cool to see, left me a tad queasy afterward.

The ramifications can be very serious. Under the “Photosensitive Seizure Warning and Other Health Risks” section, Samsung points to those who have history of epileptic seizure or stroke when exposed to flashing images or lights, to consult a doctor before using 3D.

Other symptoms to keep in mind that you may experience, notes Samsung, include:

altered vision
lightheadedness
dizziness
involuntary movements such as eye or muscle twitching
confusion
nausea
loss of awareness
convulsions
cramps
disorientation

Especially on that last symptom, Samsung advises: “Accordingly, DO NOT place your TV near open stairwells, cables, balconies, or other objects that can be tripped over, run into, knocked down, broken or fallen over.”

Other than all of that, you’re good to go. Samsung made no warnings about letting your kids watch Jonas Brothers: The 3D Concert Experience, so that’s on you.

3D FAQs from Panasonic

CIS is Charlotte NC's Choice for 3d TV Answers!

Panasonic clears up a few important technical details about 3D.

Several Electronic House contributors have visited the Panasonic Touch the Future Tour over the past couple of weeks, and we’ve each had a different take on what we saw.

Being the staff tech nerd, I latched onto a few important technical details pulled from the tour of Panasonic‘s 2010 model lineup. 

Why Active Shutter over Polarized glasses?

One bit of consumer confusion related to 3D comes from the glasses. When you go to see “Clash of the Titans” at a 3D theater or “Muppet Vision 3D” at Disney’s Hollywood Studios, you use cheap plastic glasses with polarized lenses. They’re light weight and cost less than $1 for each pair.

So why are major TV manufacturers gravitating towards heavier and more expensive active shutter glasses?

“Performance,” says Chad, the Panasonic rep on hand. “With an active shutter system, we can close off both eyes for a split second between each frame, which greatly reduces ghosting or crosstalk”.

Crosstalk is a phenomenon where an image intended for one eye is seen by the other, causing ghost images to appear. The Panasonic rep says active shutter glasses make it much easier to eliminate crosstalk compared to passive glasses where a polarized filter on the display has to switch directions for each eye.

Why plasma instead of LCD?

Another big point of consumer confusion rests in the battle between LCD and plasma. Each has its own benefits and drawbacks. Unfortunately, those differences are poorly communicated by manufacturers, especially manufacturers that produce both types. While Panasonic does produce both LCDs and plasmas, it draws a line in the sand at 42 inches; everything bigger is plasma and everything smaller is LCD. 

But why is plasma particularly conducive for 3D?

“It’s all about refresh rate”, says Chad. “With LCD technology, refresh rates are limited to 120Hz or 240Hz. With Plasma, we refresh at 600Hz and greatly improve motion perception, especially with 3D content”.

While Full HD 3D maintains full resolution for each eye, refresh rate is effectively cut in half. So a 120Hz LCD offers 60Hz to each eye; a 240Hz display offers 120Hz to each eye; and Panasonic’s 600Hz plasma effectively refreshes at 300Hz for each eye. 

What about 3D gaming on the big screen?

Panasonic has partnered with NVIDIA for the Touch the Future Tour. NVIDIA has been a player in 3D for some time with its 3D Vision add-on kit for 3D gaming.

“In the past, we’ve relied on 3D-capable monitors for 3D PC gaming through 3D Vision,” says Rambo Jacoby, marketing manager for NVIDIA. “Now, with our new 3DTV Play software, gamers can connect directly to 3D-capable TVs, without the need for the 3D Vision kit, using the display’s own 3D syncing and glasses.” 

I checked out the Avatar PC game in 3D on a 50-inch Panasonic V25 series plasma, and I was very impressed with the effect. That said, afterwards I saw an 11-year-old playing the game with no glasses enjoying it just as much. If kids are a major market focus for NVIDIA’s 3D gaming push, they may want to reflect on how to make the improvements clear to a less critical audience. 

The Panasonic Touch the Future Tour is a great event for mall-goers. If you haven’t visited yet, there are only a couple of dates and locations remaining.

This kind of event is exactly what manufacturers need to put their muscle behind to develop consumer interest in 3D and related technologies. Informed answers and hands on demos go a long way, and what I saw and heard was far more informative than any in-store demo I’ve seen to date.

Geek Squad: Let Us ‘Sync’ Your 3D Glasses

When you want expert advice for home electronics and new technology, call CIS!Do you really need to sync the Blu-ray player through the USB port on the 3D glasses?

Best Buy’s offer of 3D synchronization service is “bogus,” according to HD Guru Gary Merson.

He notes that the new Samsung 3D TV package is now offered with Geek Squad installation ($150 value) that includes TV and Blu-ray player set-up, and connection to a wireless network.

But for that low-low price, the geeks will also “sync your 3D glasses for an amazing experience.”

As Merson notes: “The offer’s only problem is that there is no such thing as syncing 3D glasses. They sync automatically.”

So he called three Best Buy stores and talked to employees that said they were trained on 3D TV installation.

Here’s what they had to say about syncing the 3D glasses:

Blue shirt one said the glasses need to be synced with the Blu-ray player. The second geek referred to the 3D glasses needing to sync to the player via the USB port within the glasses, an impossible feat as there is no USB port on the glasses. The third stated the need to acquire the glasses’ IP address to sync with the Blu-ray player. There is no IP address for 3D glasses; they have no connectivity to the Internet or network. The Samsung battery powered glasses “sync” to the 3D content wirelessly via an infra-red pulse emitted by the TV.
