I've been researching 3D displays most of the evening and have come to a couple of questions.
I've learned that LCD screens' response time is roughly equivalent to a CRT's refresh rate. A response time of 12 ms is roughly equivalent to about 60-70 Hz. If we halve the response time, we double the refresh rate: 6 ms is upwards of 120 Hz (the magic number for the 3D goodness). The requirements for the GeForce 3D are then a max response time of 5 ms, or a refresh rate of at least 120 Hz.
Constraining the discussion to LCD monitors and ignoring input lag, it should then follow that any monitor with a response time of less than 5 ms would be compatible with the GeForce 3D, correct?
This leads right to the next question: does input lag combine with response time to give the effective refresh rate for a given LCD monitor? That would explain why my monitor, an LG L226WTQ with a response time of 2 ms, will only allow me to set my display settings to 60 Hz.
My interest is saving money: I can't really afford a $300 monitor right now, but I have a monitor that exceeds the minimum requirements for response time for the 3D. The compatibility tool that you can run from nVidia's website labels my monitor as incompatible, but I'm not convinced the tool isn't just comparing my monitor name to a LIST of names rather than actually testing the monitor. So, if my current monitor will scrape by, I think I can afford the hardware to set up the 3D and play games with lowered settings (if that helps)--but I definitely can't afford the hardware AND a new monitor.

Response time is how fast a pixel can turn from one color to another, or one shade of a color to another shade of the same color, depending on the manufacturer. It's bullcrap and doesn't indicate anything.
Refresh rate is how many times per second a pixel is updated with new display information from the video card. You could have a 25 ms response time monitor running at 120 hz - it would work in 3d, just that it would be an ugly ghosting mess in any situation with movement.
