Hi.. As an owner of the nVidia stereoscopic 3D glasses solution . I am VERY pleased with the 3D effect.

As for headaches caused by eye strain, I have experienced none. There IS a feeling, not unlike the feeling you get when you see Avatar 3d in theatre(polarized glasses). Caused by focus of each eyes separately, quite acceptable though. I have lazy eyes and the stereoscopic glasses are actually good for that! I mean, there is treatments for eye problems that uses this technology. The eye focus exercise is not negative(you can google on this). As long as the refresh rates stays up, that's where eyestrain causes problems*.

I would recommend the nVidia solution wholeheartedly. The WOW factor alone is awesome. I'm a racer, one might says a serious racer. I find racing with these glasses on a whole new experience. The cockpit of the cars REALLY comes to life and light shines/reflexions are just lifelike. Since you look out a windows when you drive a car, the "out of window" feeling is cool!

I use the Samsung monitor, calibrated with Pantone Huey. The colours are great, saturation and brightness is very good(you need a bright monitor when you have the glasses on). I do see some Ghosting in some games, but with the wheel at the back of the IR transmitter I can make it disappear. I have a feeling it has something to do with the z-buffer in the games themselves cause Batman Arkham Aslylum and Need for Speed Shift dose NOT show ghosting.

*Now, the ideal refresh rate is 120hz. At the Samsung 2233RZ resolution that demands allot on the hardware. But my GTX260 SO does a great job!

Edit 2010/02/15 No more blinking/flashing, I just changed the settings found on nVidia forum. GREAT product!

Hi all i live in Australia and I currently have the nvidia 3d vision with a viewsonic 120hz monitor but I also had a zalmon 22" 3d monitor as well the funny thing is they both died on me.

my viewsonic edid died on it which is a 1 in a million glitch (edid is a chip that sends a signal to your computer telling it what your monitor can do eg name, id, refresh rate, resolution) that may be because of my gts8800 (it hates it) it still worked just no 3d and had to use vga (dvi is needed for 3d).

While I was waiting to get my viewsonic replaced (took 2 months they had to order stock) i bought a zalmon 22" 3d monitor which only lasted 9 days I had 5 dead pixels (got my money back tho), as others have said the monitor screen is many generation behind in tech and I find the screen to be of bad quality eg on a black screen has light in little blobs here and there around the screen.

that aside it did a good job I will say it is works with the most programs including youtube 3d player, nvidia 3d, ddd tridef and iz3d(didn't try iz3d nvidia and tridef were the best).
Its disadvantages were (1.) that SMALL TEXT IS UNREADABLE in 3d (and in the end why i decided to get my money back)
(2.) it is interlaced so half res but get use to it very quickly still small text is crap in 3d
(3.) very small viewing area think of a monitor box but smaller laying flat down (ya head has to always be at the right height you also cant be too far from the monitor a max of about 3 arm lengths ) so if ya want to have people watch it with you ya have to sit in a tight triangle eg first 3 bowling pins. so not very comfortable.
(4.)5ms so for fast game can be quite bad but in most cases ok.
(5.)ready to go and do 3d out of the box and includes it own player and software as well as recommending other software .

advantages (1.) supports many third party software including tridef which is awesome cost $50 tho but convert 2d videos to 3d in realtime and works with a lot of unsupported 3d games (can even make 2d games 3d) was so fun watching everything in 3d (i miss that now coz nvidia 3d vision is not supported (shutter glasses) but might be soon because of new driver features that are coming http://3dvision-blog.com/what-new-features-is-nvidia-preparing-for-the-3d-vision-owners/)
(2.)can do 3d in windows dose not require supported full screen apps (eg youtube in browser and tridef windowed and some games)
(3.) less straining on the eye then nvidia shutter glasses (tho ya get use to it also ya should be having a short brake if so which is what ya meant to do)

viewsonic vx2268wm 120hz 22" 3d monitor
advantages (1.) high quality screen with high contrast and brightness
(2.)full resolution and text crystal clear
(3.)2ms and very good overall a lot of reviews have marked this as an very very good 2d monitor
(4.)can control the depth with the wheel on the back of the shutter control box of the nvidia 3d shutter glasses
(5.) VERY VERY LARGE VIEWING ANGLE mostly the same and any other 2d display 160 degrees also near any distance so eg i watch moves from the other side of the my room on my bed (also one of the reason i kept it).
(6.)with a refresh rate of 120 is great when using 2d makes everything smooth (if ya have fast enough hardware)

disadvantages (1.) dose not suppport anything but nvidia 3d vision at the moment more support may come with future diver update
(2.)needs to be full resolution (1680x1050) screen app aka game or supported full screen shutter glasses supported programs but will be fixed with this future update http://3dvision-blog.com/what-new-features-is-nvidia-preparing-for-the-3d-vision-owners/
(3.) monitor position not very adjustable, only the tilt no height adjustment.
(4.) there is some flicker but very rare and overall 1 flick in a split second so not that bad its to do with room lighting can be fixed tho
(5.) this is the only major problem with the viewsonic and nvidia 3d vision that could all be to do with my gts8800 (which i think it is) is the transition from 2d and 3d can be very buggy at times along with the 3d player from nvidia which is poop really poop (no in 3d ui so to do and action apart from pause play and stop ya have to exit 3d to the windowed mode to skip and stuff) but dose the job and interfaces with all codecs and has nearly all view type media formats
(6.) dose not support tridef yet so not awesome 2d to 3d realtime conversion but there is the 3Dfier Realtime 2D to 3D Conversion Directshow Filter http://3dfier.blogspot.com/ which is ok some say it dose more accurate result but i find it stutters (might be my hardware again) and dose not come out of the screen like tridef so not very noticeable but is there and still improves the viewing experience.
(7.)only 120hz refresh rate at 1680x1080 but that is native resolution and should really only be used at that resolution.

I got the zalmon for $480aud and the viewsonic for $420 plus $270 for the nvidia 3d vision kit (shutter glasses + control box).

overall price aside they were both great with the viewsonic being an overall high quality monitor I just wish the viewsonic and nvidia 3d vision had more support for third party programs which will come in time. and as others have said wait if ya can i rushed and suffered there is no standered yet and i really want a full resolution polarized monitor with a decent viewing angle but they just are not out yet(unless use projectors but $$$$).

let me know if there is anything else any of you would like to know and please tell me of any other programs that work with nvidia 3d vision
ps if real can convert normal lcd to 3d with micro film that goes over the tv check it out http://www.youtube.com/watch?v=fFIeQNseEsI i wish i could find more about it

To work the micropolarizer needs to exactly match the pixels of the monitor. There are quite a few different monitorsets "out there" with different pixelations (even similar models) so they need to build a huge database of pixelations of monitors. Sheets could be made on demand i guess so there wouldn't be any need for storage. Alignment is also very precise but shouldn't cause any problems i think. Just make similar to sunfilm that you apply to car windows using a tiny amount soapwater.

Its nice to hear a comparison from someone who has tried both. Pretty much what I expected, but I happen to like the Zalman a lot. Although I am planning on upgrading to 3D Vision when the 27" monitor hits the streets.

I've got a question. I discovered that my new video card (Radeon 4890) has a deinterlacing function. Does it remove the lines from the interlacing method in 3d mode or does it disable 3d at all? I didn't like the Zalman because of this lines.

Edit (Thanks Blackshark)
The lines you see is because one eye only sees the odd lines and the other only the even lines. This is the way 3d is generated and can't be avoided. As Blackshark says interlacing filters only applies for videos. If theoretically a "deinterlacing" filter is applied to stereogaming on the zalman it would give different phenomenas depending on how the filter algorithm works but in all cases it would mess up the 3d.

You got confused with the term "interlacing".

Video interlacing traditionally associated with the video compression technique that interlaces two fields coming from pictures taken at different times. This interlacing has nothing to do with stereo3D or with the Xpol filter (used by the Zalman monitor).

In order to try and avoid confusion, keep the word "interlaciong" for the video compression domain, and use the expression "line interleave" to describe the Xpol filter input.

Just trying to make things easy. Everybody knows what interlacing is but almot nobody knows what interleaving is. At least not when associating to screenformats/funtions. A quick search for interleaving doesn't make me any wiser.
Interlacing just felt the right thing to say when explaining. I'll look it up.
Cheers!

To interleave and to interlace are almost synonyms. But when talking about video, the word "interlacing" is already used and widely known among TV/computer enthusiasts. since what happens with the Zalman monitor is a different phenomenon, you have to use a different word in order to make sure the guy you're talking to does not mix up with interlacing.

You can find the word in the file format .avi (audio video interleave) for example.

Interlacing can be described as temporal line interleaving.

In Zalman monitor, it's strictly spatial line interleaving, and it does not even support interlaced video signal, so this is not a correct term to to use.

i'm also new to 3D and for what i've read, i'll go Nvidia 3D Vision. Why ? mainly because i want a 120 hz display monitor to watch movies. Coupled with the plugin Reclock, bybye stuffttering during playback. Man, it hurts everytime i watch a movie and there are panscaped transitions, i stutters so much my eye bleeds.

that plus, for me the 3D Vision technology is the best available, i'm not in for the Zalman passive techno.

That is really funny to read someone so sensitive to this very small stuttering caused by 24Hz->60Hz conversion not being bothered at all with the one caused by 120Hz frame sequential 3D displays (to which the passive Zalman technology is immune).
I just prey very strong for you to never ever see a panscaped shot in 3D on your 3D vision display or I can assure you you will switch back to 2D instantly.

Knowing a bit about 3D, I can definitely assure you 3D vision is not the best. It's good and has great value for money, but it is not the best.

Have to agree some, you are still getting the same 60 Hz of the Zalman, the 120Hz is divided per eye. I, however, don't believe the shutterglasses are going to make it any worse. You could probably run the Zalman at 48 Hz for movies. That might not work well with shutterglasses I think. Fortunatly movie makers know about such things and avoid panning mostly. Not sure what the reclock thing is but I would worry about it messing up the 3D sync.
Warren.

The zalman image is always in sync because the images sent to it is l+r interleaved in one frame which isn't the case using 3d-vision where l and r is sent alternatingly. The frequency is 120Hz using 3d-vision but i can even be disturbed by the slight framelag which occurs in a real-d cinema using a circular polarized projector (144Hz). It's especially noticed during fastpaced scenes or pannings like Blackshark describes. The only backside with the zalman should be the narrow horisontal viewing angle and of course the halved resolution in 3d. Inspite these backdrops it actually seems like the zalman still is a very good hardware inspite its age.
Nonethless: 3d vision gives good value for the money and i think you'll be happy with it as well.

reclock shift the playback of movies to match the framerate of the monitor. If you own a 60hz monitor, only 30fps movies (TV) would look ok on your screen. Only 120 hz monitors are a multiple of 24, 25 and 30 fps.

What reclock does is for example for movies at 23.976fps to slightly play the image and the sound faster to match 24 fps and to align with the 120 hz. The difference between non sync and synced vid is amazing. I see stutterring evey time the camera pans, and i really hates it, unfortunately i'll be able to have a 120hz monitor only until xmas...

I just tested it out and the Zalman does *NOT* work at 48Hz. From what I can tell the only officially supported refresh rates are 60Hz and 59Hz.
