Stereoscopic 3D and DisplayPort
Several manufacturers of monitors and graphics cards are now testing the waters for stereoscopic "3D," although they have not converged on a common technology. nVidia seems interested in 120 Hz monitors with active LCD shutter glasses, and others have shown monitors with lenticular or passive polar filter schemes.
It occurs to me that DisplayPort 1.2, which adds support for stereoscopic 3D, might be a superior interconnect for this purpose. DisplayPort uses a pure digital micropacket architecture which is decoupled from the raster arrangement of other interconnects. A graphic card with DisplayPort could simply arrange to ship the appropriate data for two stereoscopic screens worth of data and leave the monitor to handle the specifics of how it is actually displayed. This appears to me to be a very good thing for those who write graphic card drivers.
I suggest using the massive clout of the Linux open source graphic driver community to bring this to the attention of the manufacturers of graphic cards and monitors, for the betterment of mankind.
