It is my understanding that the LCD stereo monitors will be supported on
Linux with the 185 driver series, not the 180 series. Open to
correction.
Is it really necessary to buy a new quadro card and the nVidia
emitter/glasses combo? 1) Does nVidia intend to support the 120 Hz LCD
monitors with existing quadro cards and emitters? 2) If a new card is
necessary, I think the driver should work with GeForce cards, so that it
may not be necessary to pay for Quadro.
I haven't handled the equipment myself yet, but from pictures, it looks
like the nVidia glasses may be more comfortable, but will not do as well
fitting over eyeglasses.
Cheers,
