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.

Setting it up

The monitor comes with both a VGA and a DVI cable. If at all possible, use the DVI cable. Apple users will need to purchase an adaptor like the one pictured below:

Plug in all the cables and verify the monitor is working. To get the stereo display to work, it is imperative that you turn display mirroring off. I placed the monitor to the left of my laptop, which required moving things around in the Display System Preferences. I also dragged the menu bar over to the external monitor to make in the primary monitor. This isn't so important for coot, whose menu is attached to the X11 window, but OS X pymol will drive you nuts if you have the menu on a separate monitor.

Invoking Zalman Stereo mode in COOT

Use the Draw > Stereo menu to select Zalman Stereo.

Inverted Stereo?

Put the button "Swap Stereo" into your toolbar (the bar directly above the graphics window)! By default this only has the "Display Manager" button. Do this by right-clicking an empty part of that toolbar and then "Manage buttons (add/delete button)". There, select "Zalman Stereo/mono" and "Swap Stereo".
