12. Highly Flammable
JS: The other thing we found is when they’re brand-spanking new, they burn easily. After 200 or 300 hours, they’re much more resistant to burning. With a plasma, you have to be really careful with fixed images for the first 30 days. So customer installers doing whole-house automation and all will burn in plasmas for their clients—just fill the screen completely with a white test pattern and run them for 300 hours before installing in a customer’s house. They warm up and break in. After 300 hours, I know my calibration is fixed and locked. I learned that in the IDC report, because black level changed over the first 30 days. But the average home owner can’t do that. First of all, the average home owner doesn’t have a white screen to put into a TV. Just let people know that when they’re new, they’re fragile. So don’t play video games for the first month you have it.
TG: What about plasma half-life?
JS: Phosphors always have a half-life, so if they’re talking a 60,000 hour life expectancy, 30 days at 24 hours a day didn’t show anything significant other than blacks got better and whites dropped a little. So I think the half life is way out there. But I can’t give you a definitive answer because they wouldn’t let me run them long enough. I have some here that are three years old and exhibit pretty much the same light output as they had when they were brand new. They drop some in the first 30 days, and they’ve been stable every since.
TG: Five years on, I still don’t notice any degradation in my Fujitsu.
JS: Unless it would drop in 50% increments, you wouldn’t see it. Your eyes can’t pick it up. We’re not that sensitive, which makes it kind of a moot point.
TG: But plasmas weren’t always this reliable, right?
JS: No. In the early days, we burned one in two hours. We lost a plasma panel going out for lunch leaving a test pattern on. And it was a $20,000 panel when we did it, but I wasn’t the guy who left the test pattern on. I was the guy with the meter.

Great article. Finally, a calibration article that speaks to the common display user using common English.
Damn man, another great article from you. You are one of the best writer on Tom's. Very informative long articles everytime, but never boring.
Amazing article, this was perfect timing as I am buying a plasma in a few days.
Just had to mention Noel Lee. I have now lost all faith, respect, and trust in this entire article as well as the ISF.
Otherwise, great article!
now that explains the brightness of my 19" LCD over the replaced 19" CRT, even at sRGB setting.
just recently, i played with that calibration program in Windows7. it was good enough and allowed me to reduce the red level slightly on my sRGB mode LCD.
anyways, what a good article including the interviewed expert! i learned essentials and reminded of the basics in a short time.
Too bad the article did not include Samsung's recently introduced OLED TV's. Is an OLED TV a better option than a plasma?
very good article...
theres a bit about OLED if you read carefully
Yes, and Samsung is still working on their first production samples.
What I don't get about this article is the comments about Media Center. I know several people with 4-6 tuners (I only need 3 tuners myself), including OCUR and HD, and now with support for MP4 and Netflix, Media Center is better than ever.
Negatives for mentioning Noel Lee? Do you people not know about him? Biggest thief in the industry. Educate before discriminate.

The way in which he was mentioned had nothing to do with his products besides his name being associated with them... Why don't you tell us your issue with him if you are so loving of education? Hmmmm? He was just mentioned, that is all... get a life
720p to 1080p not a worthy upgrade... >
Okay, we know here that a tech is nothing more than a monkey with a certificate trying to sell is salad...
Play Crysis on a 720p resolution, and move to 1080p... you will see the difference at 15 feet of distance easily...
dude....we are talking about TV here...not playing a pc game.
Great article. Reading what a calibrator has to say about tvs is much more meaningful than some unknown reviewer paid by x brand.
I think getting the right rgb is really overlooked nowadays. If I go to bestbuy and look at their setup I'd ask them where's the CRTs.

Thank you (all of you above, actually) for the compliment. I'm glad you enjoyed the piece.
In all fairness, though, while I suspect a few reviewers in this business are bought, most are not. I've been reviewing products for print and Web since 1998, and not once has a vendor ever offered to pay me for a favorable review. Far more likely is that we reviewers learn over time which vendors are easier to work with. When a vendor is willing to provide skilled tech support, a reviewer's guide, a *working* eval unit, and so on -- and does so repeatedly and reliably over the years -- you can't help but appreciate their efforts. That doesn't, or at least shouldn't, mean they get get a favorable review if the product doesn't merit it. It merely means that when we have to pick five products from a field of 50, reviewers are more likely to make their first phone calls to companies that will make the job of reviewing less troublesome. Try doing a roundup of 10 motherboards with pre-release BIOSes someday and you'll see what I mean. ;-)
Admittedly, you did say "unknown" reviewer...but I'm pretty sure this group (which would be all of us save for maybe a handful of names like Walt Mossberg) would be even less likely to be bribed. Why pay someone that nobody reads?
Is ISF calibration only for high end displays? How does the average consumer go about getting thier TV (LCD or Plasma) professionally calibrated? Call Best Buy's Geek Squad?

My issue with him is Monster, if you don't know about their problems, too damn bad for you, keep shopping at Radio Shack, Best Buy, etc and enjoy getting raped!
And if you mean the gentleman that is the subject of the article, I loose all faith in him for having thiefs as friends.

That's such a total non sequitor to the article though...
Its really hard to shop for an HDTV right now. There aren't many quantifiable specs you can rely on, so you really need to see them to tell how good they look, but then the TVs on display are mis-calibrated and shown in brightly lit showrooms. I somehow doubt Best Buy would have one of the Geek squad calibrate a TV on the sales floor if I asked. There are good reviews out there, but there are so many displays on the market that its just impossible to find a well written review on all of them. Its especially hard if you're looking for value out of a mainstream set that just needs to be calibrated right.

He never said they were friends, nor did he endorse Monster Cable or Noel Lee personally. Clearly, you have an axe to grind on the subject, which is fine although totally out of context given the nature and purpose of this interview. If you could find a forum more appropriate for your views, such as one specifically about Monster Cable, then backing your views with credible, objective sources would no doubt be more persuasive than unsubstantiated accusations. Name-calling doesn't really accomplish anything...unless you're in grade school. If you and Noel were in third grade together, I know he'd be very hurt right now.
