3D Shutter DLP Glasses: REVIEWS? - Page 6

ugh!!! Rainbows with optomas are worse than they were with the x102s! Now I'm afraid it may be my TV to blame.

World Cup photo was through x102s. TDF photo was through optomas.

had the same purplish streak as your world cup picture on my samsung a750 dlp with xpand 102. sent back the 102s for a replacement pair hopefully i wont see them with the new ones. also it was while i was watching grand canyon imax 3d bluray. also what tv did you see these rainbows on. if i have the same problem with the new x102 glasses i will have the panny 350 player 2 pair xpand 102 glasses and grand canyon 3d bluray for sale.

Mitsubishi WD65C9. I'll post whether I see rainbows with the Mitsubishi/Samsung glasses I'll be receiving soon. Others who have seen rainbows with x102s claim they don't see the rainbows with Nvidia emitter based glasses so maybe there is still hope for those of us who do see it. Mitsubishi cannot put the blame on the other glasses manufacturers if I see the rainbow with the Mits glasses too. If it is my TV, I'll be demanding a replacement from Mits and will be prepared to play hardball over the issue.

so do you think if i get my replacement 102 glasses i will still see the purpish rainbow

I have had 4 pairs of X102s in my possession and they all create a rainbow on my 73837 whether in 3d mode or not. I think this is inherent to the glasses. I bet you won't see it with the Mits glasses but we'll see.

I hope you don't, but I bet you will. I have yet to hear from anyone who sees the rainbow with one pair of x102s but does not see the rainbow with any other pair of x102s. The Optoma glasses are also DLP Link, so maybe DLP Link glasses have some quirk to them that is causing at least some of us this problem.

The Samsung SSG2100's (same as the ones that come in the Mitsubishi starter kit) do not work with the SSG1000's emitter even so I doubt they will work with other emitters sadly.

Being i have a samsung tv I did not want to get the mitsu starter kit which contains the converter which wont work with samsung dlp but I found that Mitsuparts.com sells the emitter from the 3dc-1000 starter kit separately! and the glasses but the glasses are $165 where as you can get the Samsung branded version (ssg2100) for $150 at the store so no shipping.

even the samsung starter kit at $350 doesnt seem worht it as thats $50 for the movie it comes with so i am probably just going to get a couple pairs of ssg2100 to work with the mitsu emitter i got separately (samsung doesn't sell an emitter to work with their ssg2100 so thank goodness mitsu uses the same glasses and does sell an emitter)

the great thinga bout the ssg2100's is that they will be compatible with a samsung 3d led lcd (which i will be gettign the 65" hopefully eventually after it comes out)

then i'll just have to sell my ssg1000's and emitter and then maybe get the converter (mitsu one hacked to work for samsung though its not worth the $100 more just for the hack so ppl are working on getting the mitsu one and doing the work around themselves)

so for now may just use the panny 350 which doesnt need an adapter and the couple games on 360 also and hopefully more games will have the option for checkerboard making no converter neccesary. i have fios which doens have 3d chans yet so if i can get away with not getting the converter and just get new 3d tv then i'll be good cus then all i have to sell is the emitter though i will be keeping my 67" sam led dlp so i guess it wouldnt hurt to get the converter...

you mean you tried the Samsung branded SSG2100's with the Mitsu emitter? yes I have assumed that works as the mitsu glasses that come with that emitter in the starter park are rebranded ssg2100's.

But the 3da-1 adaptor/converter has nothing to do with the glasses. the glasses dont need the converter. thats just for converting side by side 3d to checkerboard that dlp's display.

It's either the checkerboard format or more likely the displays themselves. On my Sammy HL67A750 the rainbows are exactly the same all the time. Nothing moves, nothing changes, no matter how many different pairs of glasses you try.

Someone did say they saw a rainbow with x102 but no rainbow with nVidia. I'm holding out hope that emitter glasses and particularly the Mits emitter glasses, for whatever reason, do not have the rainbows.

I agree that the rainbows are always the same, never move, but they don't show up on some people's screens who have the same glasses and model of TV as other people. There is some variable that we don't know about apparently.

I have the X102s and IO Display shutters (with IR emitter), and don't see the purple band or rainbows on my HL61A750. I'll try and remember to post my display settings tonight.

Note, I view everything from my HTPC, using a ATI HD2900XT.

I think it must be a DLP tech issue. I get the rainbows just like the pictures in this thread with a Nvidia setup and a Samsung LED DLP (HL61A750). Maybe the ones that don't see it happen to have the TVs set in such a way (brightness, contrast, who knows?) that they don't show up. There are a lot of variables. As of now, I've seen posts for the issue on Mits and Sammy, Nvidia and Xpand.

Well, now I have zero confidence that the Mits glasses will avoid the rainbows. Does your DLP that is LED still have a color wheel?

Mits had better be prepared to explain what the settings need to be to hide the rainbow or be prepared to feel a lot of wrath from a lot of ticked 3D adopters. They will definitely be hearing from me.

I think because the rainbows are so prevalent for some people and apparently completly missing for others that there must be some significant variation from TV to TV, whether it be 1 or more settings or purely hardware.

I have a hard time believing that Mits and Samsung would release a product with such a flaw if all TVs will do this with certain settings and yet not explain how to avoid the rainbow in any documentation. The typical DLP RBE is only noticed by some people... this is different as everybody can see it at all times on an affected TV including a camera!!

Samsung LED DLPs do not have a color wheel. So his post would suggest that the "3d rainbows" are unrelated to RBE. Given that, it's possible that all 3d displays (plasma, LCD) could exhibit this.

If someone wants to give me a specific scene/time in Coraline, MvA, or Cloudy, I'll take a look for these rainbows others are seeing.

Another dirty little secret of 3d at home possibly uncovered. I will say this, when I have viewed the Panasonic 3d plasma, and didn't see a rainbow. I guess that setup is my solution if all else fails to resolve it.

I've submitted a tech question to Optoma. I may call them to as they responded with a phone number for urgent questions. I haven't gotten a response from Xpand about it.

Martinefski did have a problem with these rainbows on his dlp with the x102s but not his NVIDIA glasses. Please let us know what you find out. I admire your tenacity.

Using x102s, a Mits 73C9, a PS3 playing avatar (the game), and Panasonic 350 playing Grand Canyon, Panasonic Demo, and Cloudy I have yet to see rainbows when using 3D.

Just to be clear, I think technically these "rainbows" have nothing to do with RBE, and I do have two different pairs of Nvidia 3D Vision glasses that were not purchased at the same time. I get the "rainbowing" (this term was coined on here in another thread I think) with either pair.

Any scene with a light background you can't miss it.

Any scene where the upper half of the screen is fairly light in color. A view of the sky is a good one, or any white screen.

For that matter, you don't even need to be viewing 3D content or even have the glasses turned on. Just put them on when watching anything.

i know ghosting is different then rainbows but I someone say on a samsung 3d led lcd something about changing a setting in the 3d options and it stopped the ghosting perfectly. something about setting it to -1 as +1 and 0 both had ghosting. but i dont think we have this setting on the dlp as the only 3d setting is off, mode1, and mode2

Are these rainbows/color bands similar to the stress rainbows you see looking at clear plastic parts through polarizing filters? Are any of the internal optics of these DLP sets made of plastic instead of glass?

http://holyjoe.org/hp/rainbow.htm has an example of this effect on lcd panels.

Yes, this is true but maybe it's because the nvidia glasses are natively supported by Mitsubishi.

I believe you may be on the right track here. I just took a look at the screen through a pair of the realD 3D polarizing glasses and I see some green/purple color banding in the same area that I see the rainbow. looking through one lens it is green to the left of purple. Looking through the other lens which prosumably has the opposite polarization, it is purple to the left of green.

x102s had a more purple looking rainbow while optomas had a more green look. So, the shutter glasses are having a polarizing effect beyond merely being LCD gate open or closed. Perhaps those of us seeing rainbows need some non-polarizing shutter glasses if they exist or a new TV.

Perhaps some Mits sets do use inferior plastic optics. My call to Mitsubishi just got more serious.

Also see it when viewed through a pair of polarized sun glasses. I believe sunglasses have the same polarization in both lenses, and the order of the green and purple did not shift as a result of that.

Do you think that the screen is the problem? Does touching the screen change the rainbow?

I briefly tried that earlier and didn't notice a difference, but I'll try it again later today. I tend to think it may be part of the internal optics, like maybe the post DMD lens or the pre DMD mirror. My guess would be for something late in the sequence, likely the lens.

Does anyone know which Mits internal optics are plastic? Different models have the rainbow so it is likely a part that is plastic for all models.

I don't know about the internal optics, but the screen certainly is.

After having used the Mits glasses and the x102s, I have to say I like the x102s more. I have prescription glasses, and the x102s not only seem to fit over better (more comfortably at least), the x102s also seem to block out a lot more ambient light.
