New DLP = NO Rainbow effect??

Bro, why dont you just go over and see how it looks and make judgement then, im sure your friend will understand if you gotta head on out.

But yes, hes right...the newer models have eliminated them from the speed of the RPMs. Mine runs close to 14,000 RPMs and there are zero rainbows, its gorgeous.

just sent samsung hls6187w back to brandsMart before the 30 day trial period ended because of the rbe.

None on my HLS6187

only 4 or 5 percent of people see the RBE, unfortunately I am in that group. because otherwise this is a great t.v.

Question though...if they are there, are they gonna be there for everything? Or do they sparatically happen?

I mean im not too knowledgable about these new tvs and stuff, so im not sure...but i game alot and how would i be able to tell if my tv does or not, like an official test?

Number One thing is if you don't see the RBE consider yourselve lucky and enjoy a great t.v. Some people test the t.v. with the dvd Sin City, they say the RBE is worse with a black and white movie.

Well the thing is lol i dont think i even know what one is...its just when i watch the screen i see a movie and thats it.

I cant honestly say i know what one is to be honest, i understand what it means, but seeing it im not sure.

Is it just seeing color after something has moved?

do a search for RBE there's a demo that shows it. I saw it the most when the t.v. was running the credits at the end of a movie,the white letters on a black back ground was terrible for me.

Ill have to check that...i think though for me all lettering and fast moving objects look solid, ill check out that demo though.

I just wanna make sure i made a good choice for the money.

It doesn't make me sick or give me headaches, but it can be distracting during certain scenes.

But arent there some sets worse than others?

Like i just read about the older models of DLP that moreso have them, but have improved DRASTICALLY with the new ones.

RBE and nausea/headaches may often be related (by all reports) but not always: I don't see rainbows -- I *thought* I saw one once, and even that I'm not sure about. But I'm still trying to deccide what to do about my new Samsung 6187, which initially gave me terrible headaches and nausea after an hour or two of watching. I've turned off the Dynamic Iris and generally cranked down the contrast and brightness, which seems to have diminished, but not eradicated, my reactions.

Wow im glad im not the only one. The first couple of days I had my Samsung hls5687 I would litteraly get nauceous just watching it for a couple of minutes. I also got little sleep those couple of days so I thought that was the cause. But after keeping my set for a week I realized how terrible DLP's were for me. How can they sell this stuff to the gerenal public and get away with it? They should at least have a big CAUTION sign infront of it.

I've wondered myself what position Samsung or the vender would take if a buyer demanded a refund after the 30-day-return-period because of eye strain/nausea caused by DLP. It's not an obvious defect and it might take some time for the buyer to realize what is happening.

DLP is an interesting technology. Maybe, if they use LEDs and get the strobe of colors fast enough there will no longer be "rainbows" and eye fatigue. But, I suspect the only practical cure is to switch to a 3 panel design.

Here's my/our experience with Samsung and the RBE-- Had a 56" HLN model for a week or so before my wife decided it was too big. We both saw rainbows -- fairly prominent ones, but as described elsewhere many times, mostly in scenes where light and dark areas meet, and often in old B&W movies.

We then traded our 56" for a 50" HLP model which had just come out. I don't know if it was the size difference, the new chip difference, or the trained brain difference, but the rainbows were much fewer and far between. After a while, we didn't notice them at all. So I think there is definitely some eye-brain training that goes on subconsciously. We had that set for about 1 1/2 years, I think.

After moving recently, we've been watching a 19" LCD for several months, but just got an HL-S5688 two days ago. We definitely see rainbows, although they seem to be much smaller and more fleeting than when we first got our DLP several years ago. My guess is that the new color wheel and higher speed are the explanation. I'm also confident that after a few days, we won't see them any more.

If you absolutely want a no-RBE guarantee, get the LED-based model, or go with a different technology. I can tell you, though, that my wife is extremely sensitive in that area, to the point where she wasn't sure she could live with a Samsung DLP. But she now realizes that they DO go away (at least in OUR experience).

My 2c.

That is so true about black and white shows. Before I bought my Sony grand wega, I was looking at DLPs. I really didn't notice any RBE until I saw a B/W western "Cheyenne" playing on one. The rainbows were very severe to the point that I was getting headaches. That is when I decided to go with the Sony. After seeing those rainbows on a B/W tv show, it seems to have made me more prone in seeing them on color movies now when I look at DLPs.

I see the RBE lots of times but it doesn't bother me much. (It reminds of the sixties.) Keep in mind that it's not the source material that causes it, but the motion of the the image on your retina as your eye moves quickly.

I seem to notice RBE most when I'm not really paying attention to the show but just casually glancing at the screen. Also I notice it more when I'm tired. But when I'm watching a movie or football game, I don't care about anything but the show I'm watching. And I love my TV.

Increased RPM should reduce the effect a lot. And of course, three-DLP sets eliminate the color wheel and RBE entirely.

Single panel field-sequential RPTVs with solid-state illumination (LEDs or lasers) will eliminate RBE because they can switch primaries extremely fast, faster than the human eye can detect them. LED-based RPTVs were shown at CEDIA this past week by Samsung and NuVision. No RBE. However, all the RPTVs shown at CEDIA (DLP versions from Samsung, Toshiba, Mitsubishi, LCOS versions from Sony and Brillian, and LCD versions from Hitachi) that I saw exhibited lateral chromatic aberrations. All the RPTV mfrs are trying to decrease the thickness of their sets and go to shorter focal length, wider-angle lenses, and these lenses exhibit more lateral color shift. These are easy to see in the corners when there are contrast differences, or when there is scrolling text. One sees green and magenta color fringes along the edges of lines.

I have the Samsung HL-S5679W with the LED light engine and believe it doesn't have RBE. I've played Sin City and other 'stress test' DVD movies without seeing anything out of the ordinary. No one else has said anything about seeing anything strange or felt sick from watching it: so far. However, I too feared the RBE of DLPs from everything I had learned about them. Just before getting my set, I looked at several other DLPs at the not-so-local-for-me Circuit City and didn't see RBE in them either though. So I may be just lucky in regard to RBE which with my luck I can hardly believe it.

I just got my first HD set, a HL-S7178. I was originally going to wait for the LED or lasaer models to come out in at least a 65" set because I am used to my 15 year old (and best TV I've ever owned) 52" Mits CRT and didn't want my 4:3 programs to be any smaller than what I am accustomed to. I just felt that the wait would be much longer than the 1.5 to 2 years, and with the premium price tag that they are already charging for the 56", I thought it would be a better financial decision to buy now, andI hoped that the faster color wheel would nearly eliminate the problem.

It's a beautiful set and actually looks sleeker than my old Mits, but I just watched the movie "Glory" from my upconverting DVD player and I see a lot of rainbows. I am hoping that I will get used to it.

The 2007 LED DLPs eliminate RBE, based on reports from those that saw them at CES. See the 2007 Samsung DLP thread for more information.

Perhaps a survey of the latest DLP-related technologies is in order--to serve as a spotter's/shopper's guide:

-Higher-RPM color wheel
-More color segments per wheel
-True 1920x1080 DLP array
-LED light source
-Laser light source

Did I miss anything?

With the cost of 3-DLP FPs coming down, could a 3-DLP RP at a reasonable price be feasible?
