HighSpeed Projector? (200hz!)

[fat-tony]

Hi!

I'm working in a research lab for the summer, and we're looking to get a very fast projector (LCD/DLP presumably). I admit I don't know a whole lot about the technology used in them.

I found a Sharp projector that claims to have a max vertical refresh rate of 200hz. Would it be actually updating the image 200 times/sec, or will it be interpolating? Is there even a projector in existance that will do actual 200hz?

I've looked around all morning, but haven't come up with any good answers

Thats probably the speed of the color wheel, since its DLP. so its actually 200hz/3colors or 4 if it has a black/white spot on the wheel as many do.

The fastest dlp projector i've seen at a reasonable price is the infocus depthQ, its used for stereoscopic projection (page flipping) hence needs a fast refresh rate to avoid flicker. It goes at around 120hz compared to the normal 60hz for most conventional dlps (although you can get some that go to 85hz).
