3D NON shutter glasses monitor
This kind of monitor is already available. You use either the polarized plastic glasses or the clip-on one (for glasses bearer) that come with the monitor. No cable, no synchronization.
The drawback is that you need to have special rendered content in order to have the full effect (a list of games is available on the site). And an NVidia card.

Also the ideal field of view is limited ; you cannot move toot much away fom the center axis.
Available online, look for ZM-M190 (19" model) or (ZM-M220W) 22" model
