3D vision seems to come and go

I remember buying a graphics card back in the 1990's that came with a pair of glasses that you connect to the graphics board. This causes only one eye to see at a time rapidly alternating between the eyes.

For active shutter glasses you can still do that, only now the glasses work wirelessly.

For the graphics card:

and the monitor...

The only magic for a 3D monitor in this case is a special cable that allows the IR emitter for the shutter glasses to be located within the monitor. This makes sense of course,m because the glasses are facing the monitor when used, and can thus see the IR emitter.

I do not have personal experience with this setup, just offering it up as an example. The active shutter glasses 3D cards and monitors are still sold because they are popular with the gamers. Personally I don't like shutter glasses because of the potential for flicker. But the technology does have advantages over passive glasses which include no sensitivity to viewing angle and presenting the 3D in full rez.

I do find it unusual that they are still selling 3D movies on blu-ray discs as there are no 3D TV's sold, maybe there was a lot of 3D TV's sold at the time making enough demand for 3D movies.

The 3D discs for new 3D movie releases can be hard to find. I usually end up buying a recent 3D movie from eBay from somebody who has imported a large quantity of region-free discs from Europe or Asia.

Thanks for the info and links Bill.

From memory the novelty of viewing 3D on my 3D graphics card soon wore off.

I still feel there is a market for 3D if they can create a good 3D system that does not include only games but other forms of entertainment and education.

The closest seem to be the Playstation 3D setup or attaching a smartphone to a pair of of goggles. Now that Smartphones are getting more high resolution then this setup might improve.

I prefer more 3D than VR as I don't want to keep having to turn my head to view things.
