Hi Jean-Marie,

If a Windows 10 graphics update, messed things up, then it would have 
broken other programs beside Chimera and you should reconfigure your 
graphics driver as described in option 2 below. But Chimera has builtin 
support for the Zalman monitors, so that is not needed.

Option 1)  Using the Chimera documentation, with the Help / Search 
Documentation dialog, and then typing in Zalman, it gives you a link to 
the documentation for the stereo command.  And that says to use the "row 
stereo, right eye even" stereo mode.  If that doesn't work, then your 
graphics driver is decades old and needs updating.

Option 2) For systems with NVidia Quadro graphics, you can get 
"sequential stereo" to work (which is designed for active 3D glasses 
that some 3D stereo TVs have. where the graphics driver needs to output 
a special signal), by reconfiguring the Quadro graphics driver.  I don't 
have a Quadro system in front of me right now, so double check this -- 
go to the 3D settings, *not* the stereoscopic settings, and (a) enable 
stereo and (b) choose the correct stereo mode for the Zalman.  Then both 
"sequential stereo" and "row stereo, right eye even" will work.

     Salut et bonne chance,
