+== Stereo using Chimera on 3-D Televisions ==
+
+March 23, 2011
+
+Matthew Baker at NCMI reports that stereo 3-d viewing with Chimera using LCD shutter glasses works from
+from a MacBook Pro laptop with Nvidia GeForce graphics (possibly GT 330M) using a 46" Samsung 3-D TV
+(Samsung - UN46C8000 46" 1080p 3D LED TV).  He reports that it worked at 720p resolution but not 1080p
+using the Samsung's built-in infrared emitter and presumably Samsung LCD glasses.  He used the Mac laptop
+mini-to-DVI video adapter to connect the laptop to the TV.
+
+This result was surprising because on non-Mac machines we believe sequential stereo in a window is not available with
+the consumer-level Nvidia GeForce series of graphics cards.  In the past at least a more expensive workstation
+graphics card, the Nvidia Quadro series or ATI FireGL was required.  The consumer cards were only able to do
+full-screen stereo (used in many video games), and not the stereo-in-a-window that Chimera requires.
+
+We believe Mac desktop machines with standard consumer Nvidia and ATI graphics cards are able to do sequential
+stereo in a window based on tests running Chimera in sequential stereo mode where the expected flickering is
+observed in the graphics.  But it is not clear whether the synchronization signal needed by the LCD glasses is
+available from the desktop cards.  We do not currently have a 3D TV to test this.
