3d glasses reviews[dlp user perspective]
  2 / 3    
I realized perhaps I was a little too harsh with my Optoma BG-ZD301 review above, since they're my first experience with DLP glasses. The ghosting isn't very noticeable at edges, unless there's high contrast/bright against dark elements. Center has ZERO ghosting. They're probably the best I could get from DLP link.

Going to sound stupid but did you try to push glasses closer to eye so you aren't looking out of edges as much? Might not be as possible if currently wearing a prescription underneath.

I'm already pushing it the best I can; it doesn't help much... Thanks. Any suggestions are appreciated :)

Hi eqzitara, Great post on the glasses. Would you consider adding my input? I have a 3000 lumen projector with a 2.4 gain screen. 3D vision 2 glasses show a lot of ghosting, albeit, not quite as much as 3D vision 1 glasses. Optoma ZD101 / DLP Link PGD-150 / other generics using the same design: No discernible ghosting at all, although angle of the lenses to the screen need to be perpendicular of course. As you say, they are darker, but presumably this ensures that rogue light does not cross into the other lens when it shouldn't, which is the sole cause of ghosting on a DLP projector. I personally feel that the positives of no ghosting massively outweigh the negatives of lower brightness, especially if you have a high lumen projector as well as a high gain screen; as you earlier stated in your 1st post. Thanks, -- Shahzad.

Same screen gain[Da-lite high power], 2500 lumen projector, non-eco mode. 75 inch screen. No ghosting with 3d vision 2's unless extreme situation. Running depth hack @ 70" screen size.

Hi eqzitara, I'm not saying that your results are wrong or less valid. Are you stating that my results are somehow wrong, or less valid? I am only saying that different hardware and even people may have different results as is obvious between your comparison and mine. Stating that 3D vision 2 glasses have no ghosting as a blanket statement for all hardware is perhaps disingenuous when another user reports different results :) Also, a higher depth does not necessarily equate to higher ghosting. The ghosting is just closer together and less apparent in some situations. Also, might I inquire as to the position of the projector in reference to your eye position? Thanks!

For what it's worth, I made some actual photographs through the lenses of my Vision 1 glasses, and it was pretty clear that there is a dark sweet spot on the lenses where it's substantially better. The lenses were particularly good at the IPD distance, and since my eyes are 64.5 cm, I fall into that sweet spot. [url]https://forums.geforce.com/default/topic/529466/3d-vision/3d-on-videoprojector/1[/url] This suggests that IPD might be an issue for glasses which are trying to be the usual one-size-fits-all and could explain different experiences.

Great pics bo3b! This is indeed strange. Please find mine below for comparison: 3D Vision 1 Glasses: [IMG]http://i.imgur.com/SRy59D3.jpg[/IMG] 3D Vison 2 Glasses: [IMG]http://i.imgur.com/zrePpF7.jpg[/IMG] DLP-Link glasses: [IMG]http://i.imgur.com/LzTvi6X.jpg[/IMG] As you can see, there is a stark difference. 3D Vision 1 glasses: You will note that the lens of the Vision glasses isn't great - no matter from which position I posed the camera, one side was dark while the other side was light. 3D Vision 2 glasses: You can see that the ghosting is still atrocious, but it is more even. DLP-Link glasses: These are the best as can easily be seen. This leads me to believe that either there is a synchronisation issue between my projector and glasses, or my image is much brighter than yours hence giving a higher contrast between ghosting vs no ghosting. With high gain screens, it is crucial that the projector is positioned as near eyes as possible on all planes. Some people make the mistake of mounting the projector on the roof or on the table on front or behind them. With glass bead screens, the image is highest reflected to the point of projection. I personally have mine sitting on a stand just behind my head. I do have trouble of my hair getting in the way at times ;-) Any other hypotheses would be appreciated :) -- Shahzad.

Well! Super interesting results, thanks for taking the effort to make the photos. I'd thought that it was IPD related, but your results show there is clearly a wide variance in experience, depending upon the glasses and something else. I had three pair of the Ver 1 NVidia glasses, and none of the three, nor the V2, show this level of ghosting. That suggests that maybe it is a timing related problem, as opposed to manufacturing variance. My setup uses pyramid emitter, V1 and V2 glasses, with an old model Acer H5360 projector on a flat-white painted wall, no screen. This was the 3D Vision Ready projector of choice at the time, and presumably is well matched to the NVidia glasses. My projector is not placed well from your description, it's 3 feet higher and 5 feet farther back from my head, but pretty much directly behind where I sit. What model is your projector?

Hi bo3b, The projector position relative to user perspective only matters for high gain screens as they reflect the image towards the emitting source. For standard 1:1 screens or no screens at all, the dispersion pattern is evenly spread so the projector can be positioned virtually anywhere, as yours is. My projector model is the ViewSonic pjd6531w. It has had a lot of problems over the years, not least of which have been shoddy firmware. I wouldn't be at all surprised if this is a projector sync issue, although in my experience, on a dlp, these issues manifest themselves as blue or red ghosting, which is presumably to do with he colour wheel. The ghosting I experience is pretty standard. However, back in the old days, I made a sync adjuster circuit and posted on StereoVision.net, which a lot of people had success with. This was designed to remove the blue/red ghosting due to sync issues. If I find more evidence that this is the case, then I shall try to rebuild it; although I'm not sure how I would get it to work with the new USB emitter. enthralled, thanks for the pics. It seems that the Optoma BG-ZD301 are on par with the BG-ZD101s. Do you have any 3D Vision 1/2 glasses you could also test with? Kind regards, -- Shahzad.

Photos aren't precise for judgement, but I think your ZD101's look a bit better. I think bigger glasses help achieve less ghosting (maybe wider sweetspot). The ZD301 has smaller glasses. I don't have 3D Vision Kit to try. My pj works with 3DTV Play only, by default.

[quote="eqzitara"]I think you can use an edid override of an acer h5360 and use 3D vision emitter/glasses but don't quote me on that. [/quote] I tried the H5360 EDID override with a separate 3D Vision emitter with my 5360BD and my results were poor, either the eyes were reversed, or the sync wasn't correct, and if I told the 3D Vision setup to flip the eyes manually by "lying" on the left/right eye setup it would refuse to complete the install. I still have the emitter and 3D Vision 2 glasses so I might give it another go at a later date, but to be honest the cheap DLP glasses I purchased seem really good, and any improvements are likely to be minimal.

Very interesting results. I can't explain why the 3D Vision glasses are bad for RageDemon, but other DLP glasses are good. As another data point, I have a different Viewsonic projector PJD 6210 that is good with my Nvidia glasses. The PJD6531w is 3D Vision Ready, so you'd expect it to be good. I tried bumping up the brightness with non-eco mode and tried all three currently working glasses and they are uniformly good with essentially zero ghosting. One thing that I did notice while experimenting is that the glasses are highly susceptible to changes in angle. As in, the lenses need to be parallel to the screen. If I turn or tilt my head, the ghosting gets dramatically worse. I had been attributing that to IPD, but that is not the case. Taking the glasses off to look at the lenses and photograph them showed they are susceptible to angles, but when active and parallel to the screen, the entire lens is dark, not just a sweet spot like I thought.

My Optoma BG-ZD301 DLP glasses aren't affected by viewing angle. I tried all possible angles and ghosting is the same; only visible near the edges of the glasses in high contrast images. So I guess DLP-link do have an advantage after all :]
