Sounds like an X-Files issue - have you been abducted lately by one of those things with flashing lights up yonder?

Nope. LCD and Direct-View CRTs are two of the three displays where I don't see rainbows of any kind. Add RP LCD and RP CRT to that list. I just have problems with DLP and Plasma. My next set will most likely be a 1080p LCD - flaws 'n all.

I saw rainbows all over my pioneer 5060 which eventually led me to return it in exchange for a 46'' samsung 469D LCD. It's really a shame - I thought the set produced and incredible picture, but the yellow trails were very distracting with all source content.

I have seen rainbows on DLP, Rear Projection CRT, and Plasma - although the colors and extent of the rainbows varied between displays. To date I have not seen rainbows on any direct view crt's or LCD's.

I got a small video on my cell phone of what I was viewing seen here:

It seems the worse with games that have a 3D camera, it not only leaves yellow trails, but it can smears the entire picture, making everything look extremely blurry.

It tested the worst on Kameo on the Xbox 360, as that seems to have very vibrant colors & that really amplifies the effect.

I'm going to test this side by side with my Sharp LCD Aquos & see which has the less noticeable trail effect, if I can't get a decent setting for either then I dumping both & getting the Sony 34" CRT at Circuit City.

I heard that Leonardo Da Vinci had plans for a TV and they built it and it had rainbows!

Jesse Jackson said he believed in Rainbow TVs.

I believe in my own dreams and can describe them. Is that the way it works for the people who see Rainbows?

Be smug and sarcastic all you want. There's still no denying that these things ARE there, and people are seeing them. Count yourself lucky that you don't.

I see them on CRTs.

The most stable displays I've encountered are 3-chip LCD and LCOS displays. I would include 3-chip DLPs, although I have heard one or two people report seeing rainbows on those, and they technically should be susceptible in a theoretical sense because it's still a PWM/PDM display. But I'm very sensitive to rainbow artifacts and have not seen anything like that on a 3-chip DLP, so I would include 3-chip DLP as pretty much rainbow immune and in any case not fatiguing.

If a display acused of having rainbows depicted a rainbow--would you see two rainbows?

Who knows--maybe if you got people to believe that some displays would show two rainbows you'd really inherit the pot of gold at the end of them!

...a little better
Ghosting on the Aquas is less prominent then the rainbows on the Plasma.
I still can't believe people haven't complained about the rainbows more then ghosting on LCD panels since it actually looks worse.
Maybe it was because the older LCD models had the high 50ms response times.

The Aquos also kicks the hell out of Panny PDP in colors & resolution.
Too bad the Aquos loses a lot of details in all the dark scenes, or I would have kept it

I am burnt out with all these problems, I'm getting the Sony 34" HD widescreen CRT & will wait till next year to get a flat panel when they sort out these problems with newer technology.

I can't believe that people do not see the trails on plasma's. Are you all freaking blind! Granted it's not always visable. I would say that durring normal viewing it does not come up that often, but durring sports or video games it's very noticable. Watch any hockey game and watch when the camera quickly pans from one side to the other. You will see trails on all dark colours against the white ice. It's very noticable. Every plasma I've seen has it. Rainbows on plasma's is not a big issue and I almsot never notice it, but the trails anyone can see. The trails are yellow or green. So you can make fun of the people on this thread all you wan't but the trails are there and you just don't see them. It's not our fault that our eyes are better then yours. My friend who works at BB never noticed the trails. When I pointed it out to him durring a basketball game, he couldn't believe that he never noticed it before. Everytime I point it out to someone they always see it.

I can't believe people rag on LCD for motion blur, when plasma is worse! What whould you rather have a slight blur or a colured trail?

Maybe the people who advocate "only reality of the object viewed" will remove the windshields from thier cars and have a complete vacuum between whatever objects they're viewing and their eyes.

Also command the sun to be putting out light at 6500K.

Also command all fences to be torn down behind home plate at baseball stadiums.

While you're at it BRAND all people who don't see every bit of visual information EXACTLY the way that you do to be unacceptable.

Define anybody who sees things you don't see on technologies you deem acceptable to be unacceptable.

In other words--GO FLOAT YOUR OWN BOAT!

If the world is as blind as you think then SUFFER for the rest of your life seeing things that bother you.

At least you'll know that you're right!

This could be my opinion but on the other hand I could be on drugs and there might be so many rainbows in my vision that I'm not stating what I know to be reality!

By the Way: I onced lived in Hawaii where rainbows were very common. I LOVE RAINBOWS!

Peace!

Artwood, that was very moving. Honestly, you are a very good writer, and I respect that. I am only stating that trails exist on plasmas and are visable. If you have a plasma yourself then please watch a sporting event and I guarantee you that you will see trails. I currently work for costco and when people ask me what is the best display to buy right now. I tell them to go for a good plasma like a Panny, Pio, NEC, Fugitsu, etc. because I know that most people will be very happy with a plasma. But, that doesn't stop the fact that Videophiles do notice things that the average person may not. I just don't appreciate people coming on a thread and making fun of others . Basically implying that they are seeing things. Trails are very easy to see. They are there, and I think that the problem should be addressed. If you don't see them, then thats good for you because once you do, you will always notice them.

Dude, it's user dependent. I've had my plasma for 3 months now. Don't see them. Before I bought, I spent 30 min at a showroom once doing all the tricks I've seen mentioned here to produce them. The finger trick , moving my head back and forth, etc. (Yes, more than one person looked strangely at me wondering what the heck I was doing.) I simply don't see them. I do believe it exists, but maybe I am lucky that I don't see it.

But really conan48, you have to get yourself a good dose of the funny spirits when you come on the forum singing like John Sebastian..."I've got rainbows all over my shoes". Funny topic, what can I say. Levity can be a good thing.

For the most part I am having problems with motion trails and not rainbows. There are no crazy tricks that have to be performed to see trails. You don't have to dart your eyes back and forth and wave your hand in front of the plasma. Trails are just that. It's a pysical trail that is on the screen for as long as the movement lasts. The easiest way to see it is with games or Sports. I know I've said this but, put on any hockey game and right when the camera pans (especially if the camera moves in the opposite direction of the players) look at the edges of the players and you will notice a coloured smear, or trail following them. It's usually green or yellow. It's not an optical illusion, there is a trail and it can be on the screen for quite some time.

Motion trails are probably source depedent. I see this too ... via my overly compressed SD satellite feed from Dish. I do *not* see this with DVDs.

Motion artifacts? Yea, I've seen them on plasmas. I've seen them on LCDs. I also see pixelation with fireworks and similar scenes on all types of displays. How do you know that what you're seeing isn't related to the source and compression artifacts and not the display? I'll bet that where the problem is. I suspect you're placing the blame for what you're seeing in the wrong place. It's not the plasma. And rainbows on plasmas? Sorry, I've never seen one on my Fujitsu. On, DLPs, absolutely. But not on a plasma. And I'm not yet blind.

I'm a critical viewer. I'm extremely sensitive to CRT flicker and to DLP rainows. I can't take watching DLPs. I was even one of the people reporting rainbow "like" image break up when viewing 3 chip DLPs. So I'm quite sensitive to those types of artifacts.

As I wrote earlier, I've never seen a rainbow on a plasma. Four years of watching the hockey season on my plasma and I've never seen a rainbow flash.

In fact, I've been on this forum since 2001 and this rainbows-on-plasmas thing is quite a new phenomenon here. I'm not sure, but I think Yoda was the first I've ever seen report it. And I've never, ever read a professional review of a plasma that reported such flashes.

So this does seem pretty user dependant, and that someone doesn't see them doesn't mean they aren't careful or critical viewers.

Ok. Forget the rainbow flashs. I don't see flashs either. I'm talking about colored motion trails, and It's visible on every source. Very, very easy to see on a videogame system. Simply get a FPS game where you have control of the camera and move it quickly. You will see coloured motion trails. Yellow or green. It's also very noticalbe on sports, and really any scene that has a panning shot. It's visable on HD, SD, DVD, XBOX 360, etc. If any of you guys live near Toronto, GTA area, come by my Costco and I will personally show you the problem on every plasma we have. I have shown this to many people and everyone I have pointed it out to see's it.

It's not hard to see. That's why I find it funny that more people don't notice it. Anyway, maybe not ALL plasma's suffer from this problem but many do. The Panny and Pio have it for sure as those were the plasmas I was considering and noticed it. After I point it out they find it very obvious, where beforehand they never noticed it. We get thousands of people everyday at Costco, so I deal with many people. I don't go around showing it to everyone who's interested in a Plasma, but once in a while I point it out
And it's not our feed and this is visible at BB, The Brick, and Futureshop, etc.

I am pretty picky with displays and I sure haven't noticed what you are talking about on a plasma.
Sometimes you can see very small shadows around objects but that is about as bad as it gets on plasma.

Display motion trails if caused by phoshpor decay will not be source dependant since it is a physical attribute specific to the display. You may be confusing other artifacts for phosphor-decay trails (which appear greenish).

As has been explained, this is phosphor decay artifacts as green is the slowest. You can see this on a lot of CRTs. These will vary depending on the speeds of the phosphors used in the display. You can see these pretty bad on direct-view CRTs that are designed to for interlaced use, some other CRTs have much faster green phosphors and won't trail at all (especially fast-green tubes tasked for 3D simulators).
