Summary: The 3D on this thing is amazing... When it works. I've read many, many threads on various forums about this monitor having a flaky emitter and it goes beyond a firmware thing from what I can tell. It seems more likely that it's poorly written drivers by NVIDIA. Power cycling isn't a guarantee to get it to work. The best trick I've found is to run it at 60hz for normal use. Generally when it goes into 3D mode it will jump up to 120hz automatically.
Pros: When 3D mode kicks in, it works great., Plenty bright, even in 3D mode., Very, very little ghosting., Intuitive menus.
Cons: 3D mode does not consistently kick in, regardless of whether the display was asleep or not. Some programs trigger the emitter, some don't., The non-physical buttons are very flaky., 3D monitors are still overpriced., 3D Vision doesn't work with OpenGL (games or anything)., Minor ghosting in 3D games, especially parts of the screen with sharp contrast., Audible hum when running at 120hz.
