Not enthused about 3D TV. Viewer tolerance is very low for picture
anomalies. Many have complained about the DLP color wheel rainbow effect,
just think about the complaints from non-3D viewers looking at double images
or the effect the 3D glasses will have on viewers over time. Besides, I
recently bought an LED illuminated set, not in the mood for a 3D TV.

Don't confuse your own preferences and tolerance, or that of a few with the
general public. I have service and sold televisions for thirty years and in
general the tolerance for picture anomalies is very high. In the case of
the rainbow effect, very few people actually are bothered by it. You hear a
lot about it on internet discussion groups and forums dedicated to
hobbyists, but among the general public it is a rare complaint.

I own a DLP and I am never bothered by the "rainbow effect". Just referring
to relevant complaints that seem indicate a low tolerance for picture
anomalies. My lack of enthusiasm is based on the added cost extending beyond
the value of the 3D experience. There are many ways to achieve the 3D
effect, good news; but also, may have unintended consequences. Its going to
be a costly "work in progress" for the 3D enthusiast; state of the art today
and obsolete next year.

I have to agree with the last statement. I'm looking forward to 3D, but
I expect to be looking forward for about 2 more years.
I was always an early adopter. I had one of the first VHS recorders back
around 1977. It was the RCA VBT200. It had picture tearing problems.
After several trips back to RCA, I ended up loosening all of the sealed
screws and adjusting it myself. I also got 5 blank VHS tapes for the
price of 4. That was $100.00.
In 1979, I bought a front projection 50 inch TV with a big fold out
mirror and 3 high voltage CRT projection tubes. When I got it home, it
had a rainbow line about 1/3 of the way down the picture. The store
where I got it said that they had several complaints, but no fix. I took
apart the mirror, and coated the edge with black electrical tape. I
called the store back, and they were very pleased to have a fix for the
other people who had the problem.
Now, I wait for industry to decide on a standard, and for the
manufacturers to work out the early problems. Then, I pay about half as
much as I would have if I had rushed in. It seems to work out much
cheaper and better.

What exactly was that? Never heard of such a TV.

It was a Mitsubishi front projection TV. It had 3 projection CRTs (red,
blue, and green) at about 24 inches from the floor. They projected the
image onto a mirror inside of a fold down front door. When open, the
door was sticking out in front of the TV at about 1 foot to just over 3
feet above the floor. The image went from the mirror up to the screen
above which was at a normal height. When you opened the mirror front
door, the TV turned on. Sony also made a similar TV at the time.
In 1979 $3,000 was a lot more than most people would spend for a TV. It
was almost a half years pay for the average salary.
I remember cleaning the big mirror, and adjusting convergence pretty
often. The sound went out on it, but I always used my stereo system for
sound. There was no surround sound yet either. And, Dolby was just a
noise reduction system for cassette audio tape.
It was well before HDTV, but it worked great for the time. I replaced it
in the 1980's with a Pioneer rear projection set. It still used CRT's,
but projected up inside the case to an internal mirror, so it just
looked like a big box with a screen. That lasted until I got HDTV with
an LCD rear projection 720P TV from Panasonic. Now, I have a Vizio 1080P
LCD wit LED local dimming.
Not bad, 4 TV's lasted me 30 years.
Ron
Do you know the model number of the Mits? Are a link to a similar TV?
Have you ever watched "The Girls Next Door"?
I'm still wondering what that out-of-date 3 screen TV is that Huge
Hefner *still* has in his bedroom.
JimH
the manual to the local elementary school when I replaced it. They used
it to show cartoons for the younger kids.
I looked for links before the previous post. I was thinking to provide a
reference. I didn't find any. Sorry, I don't remember the TV show either.

The eyes have to focus on the plane of the screen, but adjust to the
differences from eye to eye. Some people have trouble doing this.
However, you can TRAIN your eyes to do this by viewing StereoGrams!
of many, google lists this one first:

The Avatar (Real3d) glasses can be used over regular glasses, like a
pair of sun glasses, AND with them it does not matter if your head is at
an angle.

The RealD glasses are the most comfortable of all the 3D systems. I was
happy wearing them over my regular glasses for Avatar. However the polarid
systems doesn't work for TV so they use shutter glasses which are smaller,
heavier and very uncomfortable. For 3D tv to become popular, better glasses
will have to be developed. Or wait a few years for the non glasses 3D
systems to come to market.
Rick
I'll be waiting for Projection HDTV with Real3D (it requires a special
screen they say) or I become rich from stimulus money ;-)

Actually, the potential popularity of 3D tv depends on whether there
will be mainstream production and broadcasting of shows like "CSI Miami"
etc. in 3D HD, especially if 3D broadcasts become as commonplace in the
future as the current 2D HD broadcasts are now.

When I was a kid, that is what they were saying about color TV.

I've not had that problem, either with current 3D (gray lenses)
nor in the past with the older 3D with red/green lenses.
What I'm waiting for is a 3D disc release (DVD and Blu-ray)
of Avatar with red/green lenses. :)
Anybody think that this will happen?
Coz I rather doubt that they'll release much gray lens 3D
via movie disc anytime soon.
Due to the fact that there aren't enough new TV's out
there yet that are 3D capable; at least for maybe 2+ years.
It's a chicken/egg thing.

Well, that's you. We both had problems. Now, she didn't have any
problems after seeing in it regular 3D (red and blue lens) and I've
never had any problems in the past with the regular 3D.
Ron
After rereading my above post, I wasn't clear.
I didn't see Avatar with the RB "glasses", but in the past the 3D RB
"glasses" didn't have any affect on me afterwards. I believe the first
movie that I saw in a theater with the RB's was Jaws 3D.

NO. Cameron would not stand for that!

Only projection tv onto a special screen would work with the
circularly polarized lenses - what you call "gray lens".

3D TV tech,I am not interested.The kind that requires you to wear some
kind of glasses and/or goggles/head display set up is just another
redefined manifestation of the 1950's and gimmicky in my opinion.No
thanks.
Rick
Same here: active goggles sometimes give people headaches or worse and
florescent lights may appear to flicker it has been reported. Plus
the number of active goggles you have limits how many people can watch
together!
Front projection to a Real3D screen should work the best.
I predict we will have to revisit all the "specs": contrast ratio, etc.
