Using Asus 7700 Deluxe Glasses and LED monitor Advice on using existing equipment
I experimented with 3D stereo vision a few years ago with an ASUS 7700 Deluxe card (GeForce 2). That product came with shutter glasses that plugged into the video card itself. Although the technology was not totally robust, it certainly was effective at simulating 3D imagery.

I now have a NVidia 6800 card that is much faster but does not have the socket for the 7700 shutter glasses (which I still have) and I'm now using a ViewSonic 19" LCD monitor.

I have two questions that I hope somebody can help me with:

Is there some way of interfacing these shutter glasses with my new PC or would I be better off throwing them out and starting again?

I've seen some interesting (and sometimes heated) discussions in this forum about refresh rates and FPS. I believe I understand the difference - refresh rate is the number of screens actually displayed per second (or what the viewer actually is seeing) whereas FPS is the the speed at which the program is updating the video RAM (what the program is seeing). I never did understand why gamers rave about high FPS if they don't affect the viewer's perception above the screen refresh rate (at all). Anyway, my LCD (not LED as in title) monitor has a fairly slow refresh rate (75Hz maximum) and so interlacing a stereo image would give a low subjective rate (37.5Hz). That is one concern, but another is the specified pixel persistance time of 25mS which would obviously make successive left-right images blur into each other at the rates being applied. I suppose my question is what sort of stereo performance am I likely to see at this refresh rate and persistance? It would seem that it should be expected to be heavily smeared and jerky. Is anybody using a similar monitor with success?

Thanks for any advice and clarification.

Andy,

I believe the only 3D glasses that work with LCD monitors are the Edimensional glasses combined with their own special stereo drivers. Those drivers are very slow and have major performance issues in my experience, so I'll wait for nVidia to support this. I tried looking at an LCD screen through my X3D glasses once, and all I could see was a black screen. Weird.

I also had a 7700 deluxe whit a V100 3D glasses (it brings good memories to me). Now I have a 6800 GT with EDimensional wireless glasses but don''t have a LCD monitor, so I can''t tell you that them works on that monitor.

The good part is that the dongle that comes whit the EDimensional glasses have a 3.5 connector in which the V100 glasses fits perfect, so don''t throw them away. If you think to buy EDimensional, you will have two fully functional glasses.

Most people that get the glasses to work on LCD's are not happy with the results. I don't think any glasses are going to work on your LCD because of its 75hz limit. If you have an old crt it will be much better then any LCD for viewing 3d.
