Hi, this is my first post here, so hello everyone!

Firstly, I would like to thank you guys, the information I found on this forum was invaluable in setting my stereo rig up and I would probably never get my glasses to work by following manufacturer's guides!

The problem I have is that after I have been playing for a certain period of time (usually half an hour or so), the glasses get gradually darker, so that it gets difficult to see anything through them. I tried boosting gamma/brightness ridiculuously to fight it, but this results in spoiling colors and in increased ghosting. If I take the glasses off and look through them, it is as if there was a dark film unevenly covering their surface.
They return to their normal transparency when I switch them off. But when I switch them back on straight away, it only takes a while for them to get overly dark again.

Has anyone experienced anything similar with these glasses? I wrote to eDimensional's support already and I'm waiting for their answer, but in the meantime I wanted to check if it's normal?

(By the way, is it only me who feels that eDimensional is being dishonest in not mentioning the lack of driver support for new graphics cards on their website? I had to downgrade my GPU in order to be able to use their glasses...)

My setup, in case it matters:
eDimensional Wireless glasses x2
Iiyama CRT / InFocus DLP
E2180 @ 3.2Ghz
2x1GB 800Mhz 4-4-4-12 Geil Ultra
MSI 7900GTO @GTX
500GB Samsung
Corsair VX-450W
WinXp Pro SP2 + 162.50 Drivers

welcome to MTBS!

nope, what you've described isn't normal. I have the eDimensional wired glasses and in all the time I've used them there was no gradual darkening that I could notice. The manufacturer will probably confirm this.

Yes, the manufacturer is quite misleading to the newcomer. The 2 main 'misleads' are that the site insinuates that all LCD's are supported (by not mentioning that you need very high end LCD's for this), and the non mentioning of the poor driver support. I talk about this a lot on my show.

cheers!

I don't think thats normal. I've got the ELSA revelators, which are similar, and they don't get darker. However sometimes the wireless glasses can catch inference which will cause them to get un-synced and appear darker. Try moving the IR beacon around and see if that helps.

Also, eDimensional border on false advertising with what they say on their website. Its really rather dishonest.

Thanks for your replies! I was suspecting that my problem wasn't normal... I tried moving the emitter around and also I checked the batteries (although the glasses have hardly seen any use), just to be sure, but nothing helps.

Now I hope that eDimensional will have enough decency to replace them. Because the glasses spent quite a while just lying in the box while I was waiting for release of 8xxx stereo drivers (which never happened), I think they are past eDimensional's 90-day warranty already...
It's quite ridiculous by the way - even cheap PSUs, which are known to break down a lot come with at least 2-year warranty. Why these glasses, being quite a hi-tech product, only have three months?...

I get the feeling that my choice of 3D hardware company was not the most fortunate one... From the very beginnig I had only problems with them:

- First, after I placed my order they overcharged my by almost 100% and would not refund overpayment until my telephone intervention. Somehow, they mixed up currencies and charged me 163 pounds, when the actual order value was 163 USD!

- Then, I spend DAYS on futile, exremely frustrating attempts to get the glasses working on my 8600GT. Eventually, I started googling, I found this forum and one of the first things I read was "there are no stereo drivers for 8xxx series nVidia cards". Thanks eDimensional.

- After I had decided to buy a 7900GTO, the booklet with instructions as well as the software from E-D proved to be completely useless. It was not until I followed instructions found on this forum that I finally managed to get to see 3D in stereo.

- My projector (InFocus X1) doesn't work with these glasses. This isn't E-D's fault as they state quite clearly (being honest for once) that they don't officially support projectors. But it is still a great shame, because I have to choose between astonishing 100" image in "flat" 3D or smallish 19" in stereo... Is there a list of projectors that do work well with shutterglasses?

well if they indeed don't replace your glasses you can always get the 10$ xforce 3d shutterglasses (the company is going bankrupt or something and they're having a sale).

Finally someone not with a 8800 but a 8600 like me :)

my experience:
1. tried 8600+ TFT- total total failure
2. tried 8600+edim drivers+19' CRT- works, but randomly there game has incredible FPS drops, making them unplayable
3. tried 8600+nvidia drivers- crash/bluescreen on driver activation
4. tried my old pc with a 6600gts- nvidia driver works but in all driver versions when in stereo I get a big line of video card junk at the top of the screen
5. tried edim drivers + 6600- also slowdowns If I remember correctly

Yeah, I know, but I was just providing a link so he didn't have to go searching around for the URL.

Also, I believe the InFocus X1 is supposed to work with shutterglasses, but it might be the X1A model only, I'm not sure.

Welcome to the forums, uncle_leon,

What you have described is exactly the same issue i had with my edims when i used them with my X1 as well as my Samsung DLP HDTV. They gradually get darker, from the outside in, until the entire FOV is darkened. I never did find a fix for this. This was using the wireless version and not the wired version. This was the main thing that pushed me towards Crystaleyes. BTW, according to their web site they are officially releasing glasses for DLP's in June.

http://www.reald-corporate.com/scientific/

Hope they drop the price considerably as their glasses are excellent.

My first Idea was batteries, too. If they get low on power they might be slower in ... responding, so more light is lost.

The glasses get darker than without them for some reasons:
1) they have a polarizer (passive) which steals some light
2) they are black half of the time.
--> you get about 33% of the light, but it's usually still enough. I'd say the eye sees brightness in some logarithmical scale.

I can only give you this link
http://www.tomshardware.com/reviews/wal ... ,1581.html

- but there has to ba some PDF with a list of compatible (but old) projectors.

If you look into the pages of comments, you can find some good information about projectors, which ones work and which ones don't.

Your setup should work just fine. Are you using the ED Activator with your glasses? I found this helped a lot to combat sync issues. Make sure your desktop is set to 1024x768, make sure Nvidia drivers are set up so that you are using 85hz refresh at that resolution, run the test app, and enjoy! I played endless hours Painkiller with this setup. :)

You may also want to check out the following website as they have a lot of info on DLP's as well.

Good luck!

10 bucks per pair, not bad at all... Shipping to UK is quite expensive (35$), but it still works out cheaper than E-D. I will tell my friends about it, some of them might join me in true 3D ;)

As to the projector, it is capable of displaying image as such, but it just doesn't "align" well, it seems to be constantly jumping to the sides slightly, at about 1/3 of the screen refresh rate. It still gives some 3D stereo effect, especially if you set very low sparation. It's just not nearly as good as my CRT in this respect.

i constantly wonder whether the usual "glasses companies" release "new" glasses, just bundling the tridef software or updating their software so it support checkerboard (for DLPs)...or if those glasses are really technically different. If so, i have no idea what should be different for "normal" LCD shutter glasses and "DLP suitable" shutter glasses. Any ideas?

If you ask me, they are the same glasses. They look exactly like my trusty old pair of ELSA Revelators:

I'd imagine the VGA cable is different, but the glasses and the IR beacon are likely from the same stock. Probably some warehouse in Nevada chock full of them.

I thought i read somewhere that the IR emitter and receiver are different so that it doesn't interfere with some remote controls...

Yeah, that makes sense. Still, the glasses look suspiciously similar.

whow..that with the remote might be right. I notice sync-issues when i play with mine.

But, however, IMHO a LCD shutter is a LCD shutter....there cannot be that much difference, if AT ALL. So i am *assuming* they put some drivers with the glasses, supporting DLP mode..and then sell it as "new DLP glasses".

On several occasion (even in my TV manual) it says glasses are required with the standard VESA DIN connector, and the emitter and glasses should be from the same company...but it doesnt specifically say that it only works with a certain brand/kind.

you could change some parts in the electronics. If you build in some delay to get the glasses to work better with e.g. plasma...

The other thing is to build in a reverse 'switch' to swap pictures - like you need it for a DLP projector. Otherwise you'd have to rewire cables, get a retarder or make somehow with software...

well the point is i still get way too much ghosting using the ED glasses...and i wonder whether i would have this with "the right" glasses also or whether it would just be a waste of $ since the result would be the same as using the ED glasses.

Problem is i have different opinions, ED of course told me i need the special glasses and the "old" ones wouldnt work...but then this might very well only refer to the software included..(which i already have).

When i got this set i didnt expect any ghosting at all (i think it was even advertized as 3D now finally without ghosting)...but the ghosting here is almost as bad as watchign soem anaglyph.

Then i dont know what causes the ghosting...whether it also effects DLPs and only applies to Plasma???

Former user of E-D shutters. :D

I believe the shutterglasses themselves are fast enough to switch without any ghosting at all (or at least minimized to that picture that slips through a blocking glass of the shutters). This is proved by some people using dlp-projectors that's able to keep up to the refresh rate. When you're using a crt-monitor the situation is a bit different. The light emitted from a crt comes from a phosphoric layer on the inside of the tube. That layer emitts lights when hit by electrons from the cannon of the backside of the tube. The trouble is that the phosphoric layer has quite some afterglow and doesn't stop emitting light as soon as the electronbeam moves to another position. This is one thing that may cause ghosting when using crt/shutters. A way to decrease the effect of this is simply to turn down the refreshrate to a value where ghosting/flickering is bearable. When i had crt/shutters i couldn't use 120Hz refresh because of the heavy ghosting. Decreasing it to 85Hz gave the best effect for me. Lowering the refreshrate more decreased ghosting but gave me too much flicker. Have no idea of eventual afterglow of plasmascreens work though. Regarding lcd's and shutters the problem isn't the shift speed of the crystals. It's more a question of electronic bandwidth and the lag between a change of the signal until the change is noticed on the screen.

About the phenomena with glasses that successively gets darker... It has never happened to me and i used wireless E-D's. It was a few years ago though and the glasses might have been Up-(down?)-graded. :lol:

The issues i had with mine was batteryeating and bad reach of the ir'transmitter. I had to sit with the receiver at a maximum of 3 dm's from the transmitter. The viewing experince was still a joy though! :lol:

I really hope you find some fixes for your rig. Gaming in 3d on a big screen is the best you can experience! (maybe not, but it comes close. :mrgreen: )
Your beamer is a dlp and should work to some degree. Try with 50Hz to start with.

cheers

well the theory behind the "afterglow" is known to me, and with the plasma i am in the same boat as with an CRT. The problem is i dont know whether this is good now or bad.
I hear that Plasmas, in regards to "reaction times" are good and on par with CRTs.

I actually do have a software to kind of measure latency and reaction times...pixperan...this is usually used on LCDs to get an idea about the speed of a panel.
I run some tests, and in "normal" mode the plasma shows defintly better response times than even my very fast LCD (which is 5ms +/-)...when i turn on "3D Mode" than is ee a little latency coming up, probably coming from the internal algorhitms. The subjective response time of the plasma in 3D mode i would compare to my LCD monitor here, i would guess around 5-8ms or something.

Then i dont know whether this is even related to the phosphor "after glow"/latency effect which certainly exists...and its a given that there is SOME ms delay where an image might "glow" on the screen....so i could definitly see this playing a role. But its definitly not something in any way "visible", like "trails" or similar...and this is actually why people often get plasmas, for fast moving scenes etc. since they have an advantage there, now compared to LCDs or other panel technologies.

I have to say, right now, i am disappointed since the ghosting is really bad, in addition the fact that turning the glasses on also darkens the picture..so the experience as such is not as good as i expected.

Thanks for all your answers. Actually, when I tested it, the glasses start getting darker after a couple of minutes already, not half an hour. It takes a bit more time before it gets unbearable though.

As to my projector, I can't see a way of getting it to display good stereo. If I set 60Hz refresh, the picture gets less jumpy, but flickering is unacceptable. If I set 85Hz (which is max for X1), the flicker isn't bad, but the picture is very unstable. Besides, the sheer size of the diaplay buggers up stereo - the viewing angles are too far from 90deg near the edges of the screen.

Actually, I'm not entirely happy with the way stereo works on my CRT either... I mean, technically it seems ok. But playing in true 3D seems to be very tireing (or rather "strainful") to the eyes. No matter how I tweak separation or convergence, the image lacks this stability it has in flat 3D. The reason might be that I have very sensitive eyes - I seem to percept everything slightly faster than the average person (for example, the movies in cinema aren't animated smoothly enough for me, it feels much like playing a game when framerate drops and it gets "choppy"; I also have very fast reflexes - my average measured reaction time is 0.18s as opposed to ~0.30s of a typical person) - which is great of course, but it seems there are downsides as well... I'm looking with hope at InFocus' DepthQ projector, maybe that's the answer to my prayers. It's just a bit expensive...

I really wouldn't waste money on the DepthQ. You can get 2 very good projectors for that price.

Also I'm not sure what that condition is called, but it sounds like it might need either a passive setup or an HMD. Shutter glasses will definitely not help if you experience choppiness in regular 2D movies.

Any stereo 3d method that uses shutter-glasses will introduce flickering. Some people notice more than others. At 85 Hz (or even 100 Hz) you will get some flicker effect, which may make animation appear choppy. This means that the LCD shutter glasses are flipping on and off at 100 times per second (or rather, half the time you are only looking at a black screen in alternating eyes). So this effectively cuts the visible refresh rate in half. However choppy things look normally, they might appear half as smooth. With a passive system (iz3d, Trimon, dual-projectors) and using polarizer glasses you should get a smoother rate of animation. Also with a HMD, like the TDVisor, you are getting 2 full resolution video streams to each eye (generally at 60hz). You would need a 120hz monitor to get similar a similar rate with an active-stereo setup. The VR920, however, uses page-flipping so you are only really getting 30hz per eye. If the flicker is really bothering you then I believe a dual passive-projector setup (@ 100Hz) would provide the smoothest picture.

Thanks a lot; dual projector setup sounds very interesting (especially that I have one projector already!). Can you point me to someplace where I could find out more about such setups - how much do they cost, how to build etc? - I would really appreciate it.

You are already at the place! :lol:

Just look around the forums a bit, you'll find what you are looking for.

Passive dualprojection?

Look especially in the DIY section or at this:

Hey, thanks a lot, some great reading there! I decided I'm starting to save money for my new S3D setup ;)

That's the right attitude ;-)
and untill that time has comen you should inform yourself about the developing technologies - especially, which driver to use then.
IZ3D supports dualproection with their HMD output. It's a dualoutput for 2 different screens, which combine it to S-3D.

I don't think it requres any comment. I'm so heavily dissapointed with this company.

On the brighter side, I installed FarCry few days ago and it's absolutely awesome. Actually, it's probably the only game so far that I would be able to play in stereo continuously. Quite surprising how demanding it is though - my 7900GTX could only handle 1024x768/V.High in stereo while maintaining reasonable framerates. But man, how this game looks! Not even Crysis is so pleasing to the eyes!

Crysis in S-3D isn't bad either, but the framerate on gf7 IS...

No matter what I tried it was too ofthen below 20 :-(
And lately I lost all the environment and couldn't get it to run anymore. Maybe it will be the right game in 2-3 years - like it is now with FarCry :D

But have you ever seen Crysis... in 3D!!!!

All jokes aside, Crysis looks simply amazing in 3D but you do need a beast of a machine to run it. And even then, I don't think any of the 3d drivers can support S-3D in very high with DX10.

True, true.

What I meant by saying that FarCry was more pleasing to the eyes was that while Crysis has more "realistic" appearance, FarCry is more "artistic" - I'm abstracting from the actual quality of graphics, just comparing them as two pieces of art. FarCry is simply beautiful.

BTW I couldn't get Crysis to work in S3D. I could enable stereo, but the result was that all the textures were turning into plain surfaces (kind of). I haven't done too much experimenting though. I heard setting all your quality settings to Low could help, but I didn't even try. Crysis on low looks worse than FarCry on v.high. Damn, it almost looks worse than old Half-Life1 :P

To get Crysis in 3d on the nvidia drivers I think you need to set "AA":off, "Motion-Blur":off, "Shadows","Post-Processing","Shaders":low. And yes, Far Cry at max will look better. :shock:

The only way I was able to see Crysis in full S-3D glory (almost) was using the Vuzix-stereo driver for the VR920 (since it supports the 8800).

Are the vizuix drivers that good? I didn't hear a lot about them. What is their... disadvantage? Do they only support very limited games or does it run like a slideshow like with Tridef drivers?

I could imagine, that many games run good on it, since the resolution makes it easy for the GPU.

Does it support DX10? Or both vista AND xp?

@ farcry: you're right it looks nice. Like some paradisiac caribic islands. And it's always good weather with sunshine.

About the VR920. It support DirectX 8 and 9. It supports stereo in XP and Vista 32 bits. For now, it does not work in stereo in Vista 64 bits.

The Vuzix-stereo driver is very high quality, but only works with the VR920 HMD. Just DX8/9 at the moment, however it does work on all hardware (8800+, ATI cards) and XP/Vista. I have a feeling there might be a way to hack it to work with shutter-glasses (since the VR920 works based on page-flipping) but I wouldn't know where to start with that. It also syncs via USB, so it would probably need a custom sync-box or something to use with other solutions. The one issue with the driver is limited support, although there are about 30 games officially supported (probably closer to 50 unofficially) so its still not at the level of nvidia or iz3D drivers. S-3D values must be tweaked via config files (limited in-game options) however the defaults are usually perfect. But its for VR920 only, thats the reason people probably aren't talking about it.

In terms of quality, though, it is very good. No problems what-so-ever with the HUD or post-processing. Works very well with Crysis, COD4, UT2K4, HL2, CS:S, Dystopia and others, although many recent games are missing (like Bioshock, UT3, etc). The 3d effect is totally glitch free, no ghosting, no doubling-up on 2d elements, very good performance. I usually run in 800x600 mode on the VR920 and I can get decent framerates on Crysis high settings. Probably around 30fps or more. In 2D with the same settings I'd probably get around 45-50fps, so thats acceptable. Mostly anything else runs at full speed 60fps (HL2, etc.) on an 8800GTS 512MB. Even on my old machine (6800GT) it could run games like UT2K4 or HL2 at acceptable levels.

The only real downside is the hardware itself, the virtual screen just isn't big enough for a fully immersive experience. No way its going to match the size of say a projector setup or the Samsung plasmas. Which is annoying because in this market there are good drivers, and then theres good hardware, but they don't play nice with each other. So frustrating.
