View Full Version : The biggest HIDDEN weakness of Plasma compared to LCD, CRT, OLED, and other displays

People talk about burnin, dimmer picture, reflections, and other disadvantages of Plasma, but those are all flaws that can be avoided by proper viewing conditions and viewing responsibly. The biggest hidden flaw with Plasma is a DESIGN FLAW. The green phosphors on Plasma are far slower than they are on CRTs. this results in green trails on fast moving objects that can be seen by almost EVERYONE when viewing the right material. I have shot 210fps video of plasmas compared to LCDS to demonstrate how bad this flaw really is.

Plasma works by trying to fool the eyes into believing that something is one color when it's NOT. This works well with the primary colors overlap with static scenes. With fast motion though. sometimes the primary colors don't always overlap and this is what causes green trails on fast motion with plasmas.
Also, anyone who thinks that they can't see green trails on Plasmas will be convinced that they're real by watching the video below on a Plasma.
This is the DEFINITIVE PLASMA VIDEO to use when buying a new plasma.
After downloading the zip file, burn both folders onto a DVD and then finilize if needed and they should be playable on most dvd and bluray players.
I wish I had this dvd when I was buying a Plasma.
There are 2 commercials on the video, the first one is not important, but the 2nd on is the most important 30 seconds I've ever watched while owning a Plasma.

I was convinced that Plasma is a superior technology to LCD.
I was convinced of that until I actually bought a Plasma and used it for a month. Now I'm convinced that unless they do something to fix the problem, Plasma at its current stage is a more flawed technology than LCD.
With LCD's slow response time, motion resolution, and motion handling, at least they're doing things to constantly improve LCD's weakness.
With Plasma, they're trying to pretend that the problem doesn't exist.

another new thread?

haven't you already started several threads on this?

But this is the LCD forum, they may want to know about some of their advantages. They've never read these posts before.

Well if it's a HIDDEN weakness and it's related to PQ, then it doesn't appear to be much of an issue then, right?

Nice videos BTW! :rolleyes:

It's hidden most of the time, but on many videogames, tv shows and movie with fast action and the right foreground/background color combination, and certain commercials as the one I had in my original post on megaupload.com, it reveals its ugly head. All LCD owners should be happy as they don't have to deal with the headaches of green trails like on Plasma.

I guess if you're interested in scoring 'points' for the LCD 'side', then you got 'em there!

But really, if you can't see it, then it isn't a problem right? I mean crappy low-quality videos doesn't prove much, do they?

I think most people care about what they can see and which TV for the price they enjoy most watching.

Some people like vibrant colors and others like more natural colors. Does that mean someone is wrong? No.

Some people might complain about phosphor trails in Plasma and others may say it's better than the blur you get with LCD.

I think LCD owners, for the most part, are probably pretty happy with their picture and probably don't feel the need to 'defend' their choice all the time. Plasma and LCD zealots seem to spend more time worrying about the OTHER product than just enjoying their sets.

I convinced 15 people who thought they couldn't see it that they were wrong just by playing the video on megaupload.com that I burnt onto a dvd on plasmas. I convinced about 15 cc and bb employees. They said that they had customers return plasmas before because of it but they didn't know what all the fuss was about.
They thanked me for finally showing them what the customers were talking about and they were also glad that they themselves didn't get a Plasma.

My friend took home a Pio 111FD this past Friday and right away we saw phosphor lag issues.

Yeah, when I worked at Future Shop (in Canada) we had people like you come into the store and waste our time. We usually appeased them too by agreeing with whatever they said before we ushered them on their way. Good to see the people at BB and CC are have their times wasted too and it wasn't just our store.

Do you work for Pioneer or Panasonic http://www.addemoticons.com/emoticon/animated/AddEmoticons04217.gif

I agree totally with Mark. This "issue" has been beaten to death by the OP. If you really have to look to see it, maybe it's not as big an issue for people as you seem to think it should be. I'm not saying it doesn't exist, or that some people are bothered by it, but enough is enough.

You hate plasmas. Fine. Get something else. The way you're trying to "help" others to avoid plasmas is leading me to think that you have some kind of financial stake in LCD or CRT technologies.

After finally picking up both plasma and LCD sets this Friday I have to admit a refreshed appreciation for my DLP. Of course there are reliability issues with these sets, and the rainbows (which I have luckily not been trained to see).

Under ideal conditions Plasma looks best to me, but when my big DLP bites the dust I may very well consider another micro-display device for my main display again. None are perfect. Motion pictures in general have been designed to fool the eye and brain, and the various technologies do better jobs with some folks, and not others.

We all know each type of display has issues and it is fair to point them out and discuss them on these boards

But starting a new thread on the same issue every day is getting tiresome: it dilutes the issue rather than reinforces it in my opinion

If you want to discuss this in one thread, OK: but one is the limit

Nope, and truth be told, I think I'm going to buy a Sony LCD. :eek:

I have weighed the pros and cons, I have seen them all first hand, and am not bothered by the LCD motion blur.

I am limited in size to 46" and the Pana 800 is just too far out of my price range.

My point in my comments are not to dis-prove your 'facts', but to point out that the problems you outline are only problems if they can be seen. Which for the most part, with most consumers, they can not.

There are people who can see banding in Sharps and others who can not. Does that mean that those who have Sharps, and don't see the banding are somehow worse off than the Samsung owners? No, of course not.

It's the CNET reviews of products. They penalize sets for not having loads of bells and whistles. Even in their reviews they may say, "Has the best picture quality of any LCD, but without built in TV guide, we can't make this a Editors' pick". It's only a problem is you need a TV guide.

I could have gotten ANY Sony tv I wanted for 60% off coupon code for sonystyle because of my job, but I didn't because they had the slowest response time of all LCDs. They also had a Samsung accommodation, but that's over now and that wasn't that much money off anyway. If they had like a 60% off deal then maybe I'd have gotten a Samsung 950.
