Zalman Stereo
Zalman LCD Stereo for COOT
The first viable LCD monitor for stereographics display is made by Zalman and costs about $300: Zalman ZM-M220W
The attributes for this monitor have been tested and described rather extensively by Warren DeLano on the PyMOL site. Please read it for important details and suggested purchasing sources.
The following describes specifically how to get this to work with coot on Mac OS X, but the instructions should be generalizable to linux and Windoze. The beauty of this is that it is platform-independent and apparently works with pretty much any hardware (PC, mac, etc) and operating system.
