After getting much enjoyable use out of my trusty old Yamaha LPX-500 LCD projector, I finally decided to make the jump into the 21st century with a new projector. I first had an Epson 8350 in my home, followed by an LG CF181D, which I am currently evaluating in my home theatre.
While the image quality on both of these projectors is fantastic, I have real issues with how both of these projectors handle motion and pans. Doing a bunch of research and digging into technical discussions revolving around refresh rates, pulldown schemes, pixel response patterns and the various methods used by current projector technologies to effectively convey motion, it leaves me with at best an ambiguous understanding of things. What does seem evident is that I am dealing with the issue of judder - that choppy jumping motion of objects in motion and during pans. This is especially evident in medium speed motion. My old projector certainly had issues with motion blur, but it was MUCH more pleasantly conveyed. It was more of a gentle, relatively smooth and natural blurring. From my reading, it would seem that the new projectors with their 120hz refresh rate should only improve on this, but it seems to be quite the opposite. Motion is basically rendered on both of these projectors in a choppy, shaking almost strobe like quality. Frame interpolation, of course, smooths this out, but this is not an effect that I like.
It may simply boil down to the fact that the higher resolution projectors are simply showing more and vividly displaying those frame gaps rather than just blurring things together? Perhaps the implementation of new techologies is responsible for this?
I guess I'm looking for some insights or advice on this. Bottom line is that, while the image quality of the new projectors is great, the manner in which they handle motion is IMHO not so great. If I could get that 1080p image quality with the old 720p projector's rendering of motion that would be awesome.
