RS2 Image Noise
I ran the 1080p HQV disc, and found that overall, the RS2 performed excellently. it uses Gennum processing - one of the most highly respected brands of image processing solutions, also used by Marantz, and in some higher end Optoma's. No noteworthy issues detected. Background noise levels are very good, jaggies are not an issue at all, and regular motion artifacts were not a problem.
I have, however read about occasional complaint (on the forums) about motion blur on high speed movement on the RS1, and that would carry through to the RS2 as well, I believe. Now I can easily spot 3:2 pull-down, so its not that. When viewing content originating as 1080p 24fps, where 3:2 pull-down is not needed, if there was motion blur, I couldn't see it. This may be something like rainbow effect, where some are more sensitive than others. Of the emails I've received from owners, none have mentioned it, but... if like rainbow effect, it may only affect a very tiny portion of the population.
Theoretically, motion blur would come from the relatively slow speed at which the LCoS panels (or LCD panels) work at, compared to DLP. (Motion blur is also occasionally reported on LCD home theater projectors.) I wonder, however, if some of the reports are people seeing 3:2 pull-down. I'll keep looking for motion blur, and I'll let you know if/when I find some.
