hello!
i got 3d vision glasses few days ago and instantely have a problem with visual effects everywhere i use stereo mode - movies, games (any) and with nvidia logotype in nvidia control panel
the point of the problem is in aura of all objects. when i shut one of the eyes i can see the other eye's image, but much more faded. this happens with both eyes - right and left eye still can see not their frames, but this frame more pale. anyway this images are good seeing enough and i just cant ignore them at all but i training to ignore for a while and have some good result with ignoring =p. this effects applyes much of all when som white object is on the dark background. images have green color but i can say exactly cos aura is too pale. green or some blue tint.
i have gtx 295, cor2 due e8400 (OC 3.8 - anyway i tryed start on nominal speeds - no effect), 4 gb ddr3. monitor nec fp1375x, 100HZ on 1600x1200, 120 HZ on 1280x1024. plz help somebody, i spent much time with searching monitor like mine one and dont have any wish to buy LCD monitor becouse i really sure that this technology still sux for gaming =(

I think you experience "ghosting". I have today received my Nvidia glasses and I´m using too with my CRT monitor (samsung syncmaster 997MB), and I am really surprised with te BIG ghosting.
I have installed nvidia driver v1.08 and it does not recognize my CRT monitor in the begining test, but I can enable CRT once I enter in the stereo properties, and it works. One thing strange is that refresh rates are not saved well, and sometimes some games works with a 60hz and other games with 120hz, also selecting always use this refresh rate in the driver. Nvidia must include a "refreshlock" option in the driver, for all people with CRTs.
I am going to explore more the driver, but this ghosting level is not aceptable, it is not playable in most games, not only in dark scenes.

probably it is ghosting endeed
the problems with reshresh rates in some games under Vista is known issue - some games (crysis ect) have their own reshresh rate "control" and ignore any others sets include reshresh lock soft. playing with individual game and refresh locker can give some good results, but you may not reach top rate of your monitor for this resolution.
but anyway i dont think that problem with top rates in games have straight relation to "ghost" effects. this is another problem i believe

I have replaced CRT into LCD 2233rz recently
then
i could definitly know CRT has even more ghost than 2233rz
There is a big difference between them on ghosting problem

The ghosting on CRTs is caused by the afterglow on the fluorescent layer of the screen. A way to reduce this effect is increasing the time between subsequent frames, i.e. lowering the refresh rate.
With my 19" CRT, the ghosting is very pronounced at 120 Hz, it gets better at 100 Hz, is still noticable at 85 Hz and is almost gone at 72 Hz. Though 72 Hz (i.e. 36 Hz per eye) is a terrible strain on the eyes, this allows me to increase the depth without getting too much ghosting, so the perceived 3D effect is much better.
So in order to minimize ghosting, do the following:
- Reduce the refresh rate to the minimal value that is still tolerable for you (the shutter glasses will work all the way down to 62 Hz)
- Reduce the depth setting to decrease the distance between the image and the ghost
- Adjust the convergence setting (Ctrl+F5 and Ctrl+F6) so the objects in the foreground are focused (you will get more ghosting with objects that are farther away, but it's less noticeable there)
- Play with the brightness and contrast setting of your monitor
Sadly, it always seems to be a tradeoff between ghosting, flickering and depth. I guess I'll have to get a compatible LCD once a viable model hits the market (I'm looking at you, [url="http://www.computerbase.de/bildstrecke/25806/3/"]ASUS VG242H[/url]).

Yes, I don't think there is any way to eliminate ghosting on CRTs. From what I've been reading there is some amount of ghosting on 120 Hz TFTs as well. A 120 Hz TFT with black frame insertion should be a near perfect solution (though at the cost of an even greater loss of brightness) but I don't think there will be any such displays in the near future.
For me, the best compromise between flickering and ghosting seems to be a 90 Hz refresh rate, provided there are no light sources in the room.

simply the difference is not as big as you probably think. the most effect of ghost reduction have dark objects on bright background. bright objects on dark background bring no visual difference with decreasing refresh rate

I have the same problem with my CRT (green/blue ghosting).
I'm not sure why it is this colour, but it is very obvious. Also, due to the way CRT's work (starting at the top-left, and moving their way, slowly, to the bottom right, the bottom of the screen) actually reverses for me... (ie the bottom inch or so, I see the left image in the right eye, and the right image in my left eye, and the ghosting gets worse through the whole screen as it gets closer to the bottom [there is absolutely no ghosting at the top of the screen])
I kind of expected this, and Im pretty sure its due to the glasses syncing with the moment in time the frame begins to be displayed on the monitor (the very top of the screen). I plan on trying lower refresh rates, on the lowest resolution i can get, to reduce the horizontal refresh rate, and therefore reducing the amount of time the screen takes to refresh, so the reversing at the bottom of the screen does not occur.

i got 3d vision glasses few days ago and instantely have a problem with visual effects everywhere i use stereo mode - movies, games (any) and with nvidia logotype in nvidia control panel
the point of the problem is in aura of all objects. when i shut one of the eyes i can see the other eye's image, but much more faded. this happens with both eyes - right and left eye still can see not their frames, but this frame more pale. anyway this images are good seeing enough and i just cant ignore them at all but i training to ignore for a while and have some good result with ignoring =p. this effects applyes much of all when som white object is on the dark background. images have green color but i can say exactly cos aura is too pale. green or some blue tint.
i have gtx 295, cor2 due e8400 (OC 3.8 - anyway i tryed start on nominal speeds - no effect), 4 gb ddr3. monitor nec fp1375x, 100HZ on 1600x1200, 120 HZ on 1280x1024. plz help somebody, i spent much time with searching monitor like mine one and dont have any wish to buy LCD monitor becouse i really sure that this technology still sux for gaming =(

probably it is ghosting endeed
the problems with reshresh rates in some games under Vista is known issue - some games (crysis ect) have their own reshresh rate "control" and ignore any others sets include reshresh lock soft. playing with individual game and refresh locker can give some good results, but you may not reach top rate of your monitor for this resolution.
but anyway i dont think that problem with top rates in games have straight relation to "ghost" effects. this is another problem i believe

For me, the best compromise between flickering and ghosting seems to be a 90 Hz refresh rate, provided there are no light sources in the room.

simply the difference is not as big as you probably think. the most effect of ghost reduction have dark objects on bright background. bright objects on dark background bring no visual difference with decreasing refresh rate

I'm not sure why it is this colour, but it is very obvious. Also, due to the way CRT's work (starting at the top-left, and moving their way, slowly, to the bottom right, the bottom of the screen) actually reverses for me... (ie the bottom inch or so, I see the left image in the right eye, and the right image in my left eye, and the ghosting gets worse through the whole screen as it gets closer to the bottom [there is absolutely no ghosting at the top of the screen])
I kind of expected this, and Im pretty sure its due to the glasses syncing with the moment in time the frame begins to be displayed on the monitor (the very top of the screen). I plan on trying lower refresh rates, on the lowest resolution i can get, to reduce the horizontal refresh rate, and therefore reducing the amount of time the screen takes to refresh, so the reversing at the bottom of the screen does not occur.
Thanks
