Will they ever fit that problem?

LoL, nope and just sold my 56" HLS Samsung because of them....

The Samsung 56" LED model does fix them. Other than that, you'll have to wait for 3-chip models (if they ever come out in RP DLPs) to eliminate RBE. Fortunately, most people don't see them anyway.

what model do u have,i was just about to buy the HLs5686w over the sonyKDF50E2000 because i wanted a 56" tv.. Is this the 1 u just sold??

I was about to buy a 5686w ontill I went to my friends house that has a dlp and was'nt able to deal with all the rainbows I saw. I was surprised because I never saw them before at the stores. I ended up buying a 55E2000 and been very pleased so far.

I've been able to see them on every samsung I've ever looked at.
However the mitsubishi I couldn't see them even if I tried

It's not an issue if you don't see them. If you do, then move along; problem solved!

That makes no sense. It must have something to do with different calibration settings or a different viewing situation (one being in torch mode on a showroom floor, for example). If you see RBE, you'll see them with all DLPs except for the LED models.

It could also have to do with the color wheel's speed, right?

I never see them with my STB and samsung dlp, but occasionally I will notice them when watchign DVD's. Not a deal breaker for me.

I actually doubt it (IMO, color wheel speed totally eliminating RBE is just marketing hype -- those very prone to seeing RBE have complained with all DLPs, regardless of speed).

Put another way, if you see RBE, I would not count on one brand being better for you than another, but rather would avoid all color wheel-based RP DLPs (again, except for the LED models).

you're crazy I can see them on both

Do you the people even care, that people see rainbows! Plus we had to take their tv back because of it. Why don't they fit the problem!

Well I think the point that other people have made here is that the problem has been fixed by the use of led's and/or chip systems(that do not currently exisist in rptv's). Color wheel technology is flawed, but it only affects a small portion of people. For myself I have almost never seen it. My father has a 43 inch DLP and it's never an issue because the screen is small enough that my eyes don't pan accross the the screen usually, but I have done it before and seen the rainbow effects. Maybe with a larger model I would see them more, but when I installed a HP dlp for a friend of his I never saw it either.

They are not going to be able to retro fit all these coor wheel units and "fix" them, but they have been making steady progress in reducing rainbow effects. I think Sammy, NuVision, and HP all have LED model out or coming out. Mits is supposedly working on a laser solution as well. That being said I bought an LCD rptv becuase I am not a fan of the color wheel.

I've got a Sammy HL-S6187W and I can't see any rainbows for the life of me. Thank goodness.
I am VERY sensitive to crap like this too. I cannot own an LCD screen because the response / ghosting gives me a headache and drives me nuts - even on all of the brand new ones (when nobody else notices ghosting.)
I feel sorry for those that can see DLP rainbows 'cause I know how frustrating things like that are. I hope they fix it for y'all's sakes.

but it only affects a small portion of people



But it should of been made to affect no one, but it does!

So buy the LED model, the D-ILA, or an SXRD and be happy.

you're crazy I can see them on both

The new Mits sets are less prone to rainbows than many other models. The faster wheel, and the 6 color segments on the wheel have made a big improvement. I would not say that they are totally eliminated for all viewers, but the 2007 models may be worth a look if you like some of the other advantages of DLP.

I can occasionally see rainbows on the current HLS Samsung sets as well as most other DLP sets, but I have yet to see one on my 65732. I spent hours watching this set before pulling the trigger. I was considering a JVC HD-ILA set instead. It was also very nice, but I am glad I spent the time evaluating the Mits. So far, no rainbows, and the set rocks!

But it should of been made to affect no one, but it does!

-LCD displays shouldn't ghost, but they all do even the 2ms ones, but it only affects some people it should have been made to affect no one.

-Plasmas shouldn't show green flash, but it only affects some people, it should have been made to affect no one.

I can only see rainbows on my new Toshiba 50HM66 if I make myself see them. It's one of the reasons I picked the Toshiba. Of the Samsung, RCA, and this model, the Toshiba had the smallest rainbow affect on my eyes. None of my friends notice it at all.

But it should of been made to affect no one, but it does!
There is no technology that is perfect for everyone. I see horrible SDE with plasma, but I don't start threads complaining about it. You have many other options, including LED DLPs, RP LCDs, LCOS, plasma, flat panel LCDs, and CRTs, so just pick one of them instead.

I am the only one in the family that can see the rainbows on occassion with my sisters 61" Sammy. What is weird, while watching ESPN on Christmas I saw nothing but a beautiful picture for two full football games. On a separate day TNT I think showed Spiderman-2, and the rainbows became too distracting. It was so frustrating.

For SDE, I figure if I sit a foot for every 5" of diagonal measurement, I'm cool. For my 50"Panny LCD and Dell 42" Plasma it works well for me at 9-10 feet, but the Dell Plasma's blacks turned green for some reason.

HI I have two Mitsubishi HD TV WD62725 and WD52628 and I get no rainbows. I watch them in bight light and very dark rooms. I think it might be there 6 color wheel that no body else has. http://www.mitsubishi-tv.com/

I pick on it, cause I like DLP and wish I didn't had to take it back :(

Spidergames what set are you tacking back? Some are worse than other.

WOW that's great news! I am awaiting (anxiously!) my delivery this Thursday on a new 65 inch Mits. Diamond series (65831)

All this talk about rainbows scared me!

FWIW, LED based one-chip DLP displays will still show rainbows for the same reason the color wheel based ones do-- a single chip DLP can't project all three primary colors simultaneously. However, LED-DLPs should have less RBE because LEDs switch quicker. With LEDs the switching time of the DLP becomes the limiting factor.

The solution to rainbows is straitforward, but expensive; 3-chip design. Lots of pitfalls with that too, though. Not only would the chip cost increase, but the light engine would become significantly more expensive. Then there are issues like convergence, and color uniformity problems like those seen in LCoS SXRDs.

......and color uniformity problems like those seen in LCoS SXRDs.

Not to get off topic, but I was planning on purchasing an LCoS next within the next two years. Is this an SXRD specific problem or an LCoS problem that affects Brillian and JVC also?

Or it might be that you just don't see rainbows! I have a 3 1/2 year old Samsung DLP and have never seen a rainbow in my life. Most people don't see them with any brand, and others see them with all brands. This kind of claim, IMO, only causes problems since people who see rainbows could run out to buy Mits DLPs, and the majority of those who are prone to see rainbows will still see them.

I see in all DLP's, But I had a Mitsubishi TV and I loved it! Damn those rainbows :( :mad: :(

Walking around showrooms at bestbuy, tweeter, circuit city etc etc.
Thats what I saw. I didn't really pay attention to any other brands since my choice was between the sammy and the mitsu.
Saw rainbows on the samsung and not on the mitsu....and it was across the board on ever one I looked at was the same. So I wound up having to pony up the extra for the mitsu over the samsung I originaly went shopping for.

First post here. I just bought a Samsung HL-S4676S, and I'm getting a lot of rainbow effect. I often see them when I glance away from the screen, or when I blink. They seem to be more of a problem with dark program material. I was watching Star Trek Nemesis on DVD, and there were rainbows all over the place, especially when there was a dark scene. I think they're worse when watching dvd over component then they are with the Dish Network HD HDMI connection. Still, if I'm watching a nature program in HD with outdoor scenes, earth tones, browns, greens, etc... the large washes of rainbow color in my field of vision are very distracting, and pretty much ruin the vibe of the show. And they make the sci-fi stuff way too busy.

I'm sitting about 15' back from the screen, so it's not due to being too close. I guess DLP is just not for me then, at least not the current crop of sets that use the color wheel technology. I don't like the motion blur/pixelation that I see on lcd sets either, so I may just have to go with a plasma. I really like the aesthetic design of the 4676 too, and I need a set that can fit nicely in a corner as this one does. It's too bad, as I had really hoped I could just buy this set and be happy.

BTW, I looked for an official owner's thread for this tv and didn't find one, so I posted my thoughts here.

5sonic, I have the same set and I sit approximately 12' away. Since I bought this set 5 weeks ago I can honestly say that I have never seen a single rainbow. It is very specific to only a small percentage of viewers. Too bad.

I could stand watching a plasma too but they use between 400 and 500 watts of power and create a lot of heat. Plus I would have to stretch all 4:3 programming to avoid burning the screen and I hate that sretched look.

Have you looked at the new LED DLP sets that arrived this year?

I see rainbows on all color-wheel DLPs. In fact I gave up on DLPs for this reason. The new Mits set with the higher speed 6-segment wheel makes the rainbows 'smaller' but they are still there for me. I cannot see them on the LED based sammy. I'm hoping their new crop of LED based DLPs coming this year will be a winner for me, otherwise it's LCoS for me. The rainbows really stress my vision and quickly give me headaches.

Interesting that the comment is often made that "a small percentage" of people can see rainbows, but from reading this thread I wouldn't call this population 'small.' I read some time ago that the estimate was about 30%. That is significant to me.

I could see them on the 2006 Samsung LED BL set. On their 2007 set I couldn't. TI was showing off a LED backlit set in their booth at CES that had the equivalent of a >20x color wheel. It was great. Finally a single chip DLP set without rainbows.

I have two Samsung DLPs - a 43" and a 50". From the time I brought the first one home, the 43" HLN437W, nearly 3 years ago now, I noticed that I could see rainbows in dark scenes if I panned my eyes back and forth quickly across the screen. I have also seen the rainbows on my 50" HL-P5085W, in the same manner. The odd thing is that after having these sets for 2.5 to 3 years, I don't even notice rainbows anymore. I'd go out and buy another Samsung DLP without hesitation.

As others have pointed out, all of these technologies have their problems. I would never buy a large screen LCD again, because the response time issues really bother me. The ghosting gives me a headache. I notice it far more than rainbows on a DLP. Everybody is affected differently by different things. I certainly wouldn't begrudge someone for purchasing an LCD, in fact I own one myself a 36" Samsung in my bedroom. It looks great - ghosting irks me. :)

You cannot possibly estimate the % of people who see rainbows based on the responses to a thread called "DLP Rainbows." Based on strong DLP sales, the true number is nowhere near 30%.

I have had my Mitsubishi for 5 months, and asked everyone who has watched it if they see rainbows. No-one does, so I suspect the percentage of people in the general population who do is fairly small. As you point out, the robustness of DLP sales also suggests this has not been much of an issue with Joe six-pack. (I would still like an LED set because of the lamp and color wheel longevity issues though.)

-LCD displays shouldn't ghost, but they all do even the 2ms ones, but it only affects some people it should have been made to affect no one.It's not the speed of the LCD, it's the fact that it's a motion hold display, not an impulse display like a CRT or Plasma that causes "ghosting" or "bluring". Most of the major LCD makers had 120Hz LCDs on display at CES that fixed the "blur" or "ghost" problem.

As an owner of an RP CRT, looking to upgrade to a DLP display, I recently went to my cousin's to calibrate his HLS6187 (the same HDTV I was looking at getting). Changed gamma settings to 0 in the SM and used AVIA afterwards. To this point I hadn't noticed any RBE and thought I was in the clear. Popped in Sin City because I thought it would be a good test for the blacks/detail. Here's where they showed up dramatically. not sure if it was the disc due to being black and white or the 480p resolution, but it was so bad I immediately turned it off.

Well this crossed this model off my list. My eyes tend to pan quickly across the entire screen, because I tend to focus on the PQ rather than the movie itself. I'm sure if I just sat there and watched the movie, I'd be fine. But I don't. I'm constantly shifting my eyes all around the screen looking for artifacts etc.

So, I was under the impression that LED would completely eliminate RBE, but it was stated earlier in this topic that it doesn't. So what gives? I'm not a fan of LCD or Plasma at all, and I don't like the companies that make LCoS. Eventually I will be getting a FP, and if I have this much of a problem on a 61" DLP, what's it gonna be like on a 110" screen??

I talked to one of their engineers about it. He said their LED prototype was equivalent to color wheel that was better than 20x. He didn't seem to want to say exactly what the speed was.

I think the newer generation of LED DLP sets finally fix the problem.

How far away are we from FP LED DLP, if ever?

Thanks

FYI
I just bought a new Samsung HL-S4666W on super-duper sale at Fry's. This is the
'new' model with 14.4k color-wheel. The RBE is clearly visible but bearable because it mostly only happens during the credits when there's white text on a black background. And it's only visible when I flick my eyes up/down. So, while it's clearly still happening, its effect is limited.

Yep, I was also going to report that after 3 days of watching my HS-4676S, the rainbow effect is most visible when there is a contrast between black and white. I'm considering keeping it, we'll see. I too got a great deal on mine at Fry's.

I only get RBE when playing the XBOX on my Sami HLS5086WX. Games or dvd's. I have the xbox connected to the tv via monster component cables. I dont have RBE with my dvd player or anything else. It has to the either the xbox or the connection because when I play dvd's via my xbox, I will see RBE on the screen. Anyone have any ideas?
