Actually, one of the main problems with our current projector
is the lag: it only shows the input with a delay of two frames,
which at 60Hz is about 34ms. We would want something that
is a bit faster. A higher frame rate would also be nice, but the
main thing is the input lag.

We use this Panasonic projector. It goes up to 85 Hz, though we usually run it at 60 Hz.
It works well.

You need to buy a non-standard lens to project onto a small screen at a short distance properly, see the "throw distance" calculator:

This is quite difficult with the standard LCD monitor and our LCD projector. Does anyone have a setup for refresh rates of 85Hz? What type of DLP monitors are being used successfully for MEG vision studies?
