I wonder if the 40" will work with the Nvidia glasses?

Seems rather pointless unless they change how LCDs refresh.

Have a read of this thread and watch the movie-

If it's taking 1/120th of a second from when current LCDs starts drawing a frame to when they finish, I just don't see how they could do 240 Hz. This isn't response time we're talking about, but how long it takes them to program the pixels with the new frame. They refresh pixels from top left to bottom right in scanlines just like a CRT. Basically the frame is only just done when the next one starts being displayed, so you almost always have part of one frame and part of another on screen, which is bad for a shutter glasses 3D solution. This is why nVidia can only have each shutter open about 20% of the time, rather than the ideal 50%. I don't really know the details of how the electronics inside LCDs work, but it seems that either the chips in them are too slow or they have a bandwidth bottleneck somewhere.

can the glasses do 240? I've gotten them up to 170 I guess I could try 640x480 at 240.

Yeah, you should try. If the glasses can do 240... man oh man, that would be sweet. No more flickering, ever! And vsync wouldn't be such a skill destroying gamebraker.

Andrew, do you have any information on this? Wondering what the resolution, price and release date will be...any chance the faster refresh rate could decrease/ elimiate ghosting?..
