I wouldn't say it was a night a day difference, but if compared side to side, one could definitely see it. Improvement is always a good thing. One more thing to note is that in doing the before mentioned optical improvement, they were also able to reduce edge breakdown during motion. For instance, usually on most projectors if one is watching a sporting event, the black and white stripes of a referee's shirt tend to break down along the edges. With this improvement, that has been eliminated, which is increasingly important when using frame interpolation ("Clearmotion"...see below)."

Unless "motion blur" is a different artifact, but I just know it looks much better now than on the RS1 & 2 in this area.

When people speak of motion blur with the JVCs they are generally referring to a softening of the image, a loss of resolution or "blurring" when the image moves (for instance during camera pans or action). Similar to the way LCDs tended to smear motion compared to other technologies like plasma or DLP. (That is, until recent "band-aid" innovations like using frame interpolation to sharpen moving images).

Oddly it is much worse when objects move from right to left than from left to right. If you want to see this in fully glory try the Misc. patterns on the AVS HD 709 calibration disc. And yes, its not just with test patterns, you can clearly see this same affect often when watching regular content (scrolling news tickets, referees etc).

The pattern I am referring to can be found on the AVS HD 709 v1.3 PATCHED disc. In the Misc. Patterns menu, Section I "deinterlacing pattern (1080i)". It cannot be missed with this pattern. Please give it a try. I would be really surprised if it looks nice and clean on your RS20. Instead I anticipate you will see the moving boxes turn pink as the slide, particularly when moving right to left.

Please give it a try when you have a chance and drop a line back with what you saw. Thanks.

I have never seen this artifact at all, FWIW, not even on my RS1. Could be that I will curse you tomorrow for pointing it how to spot it.

Also if you have a PS3 there is a ticker in the top right corner on the main menuing system. Since PS3 firmware 3.0 now uses finer, smaller text for this ticker the problem has been worse. And of course you can see it when watching the NFL. Just watch the refs jerseys.

Thanks for the feedback Jon and for checking this! Basically the best way to describe it is this - on the RS20 (and presumably all other models prior to the RS15/25/35), as the boxes slide horizontally the thin white lines that run through the boxes turn light red.

In other words, if you look at the boxes closely (OTTOMH) you will see they are made up of intermittent lines/pixels, which forms a white or gray lines within the boxes. As the slide those intermittent lines turn from gray/white to a redish/pink. As soon as the boxes stop sliding, it turns back to its normal color.

If you do not see any red fringing in the box while it is sliding, so that its color is the same as when it stops at the edges, then we have good reason to believe it is resolved.

Also please try watching CNN HD or another HD channel in 1080i and watch the scrolling new ticker at the bottom. Does it look nice and white? If the issue is resolved then you should not notice ANY color change in the ticker when you pause your DVR. For instance on the RS20 it looks fairly white, but then when you pause the DVR to freeze the ticker from moving, you can see it instantly turn a more solid white.

Oh and another thing to check if possible - do you have a PS3, or any other way to display 720p? If so, please have it display 720p and then switch to a 1080i signal. Try switching back and forth a few times. Do you get a random splash of color on the screen for a split second (somewhere between 25-100% of the screen turns a certain color for a split sec)? This is something else that would be nice if they have resolved it.

Don't get excited though - I'm just a newb..

Here are my impressions:

I upgraded from a BenQ 8720 so this is my first 1080p, LCOS, High Contrast projector.
My main fear was losing the "wow" and "pop" by switching from DLP to LCOS.
When I upgraded from my Panny AE700 to the BenQ I immediately noticed a new amazing level of clarity & vibrancy. I was really hoping not to give that up when switching to the RS25 for increased contrast and a more cinematic experience.

Any single chip DLP owners with this same concern can (in my opinion) lay their fears to rest. I'm still seeing that same level of clarity and vibrancy in the image and it actually looks even richer now due to the contrast boost.

Jason calibrated my projector and the difference in color over my last projector is appreciable.
The one tweak I'd like to make is switching the gamma from Normal to Custom 2.4
This really seems to give the image the pop I love but I'm concerned that doing this will negate Jason's professional work. Would this be true?

So far I've only spent 90 minutes with it after setup and that was mostly spent watching parts of the Dark Knight and playing around with my PS3 and 360. You can really tell the difference between 720p and 1080p with games but I didn't notice the resolution bump during the movie. My wife is holding a movie night with her friends so I'm stuck upstairs writing about it rather than enjoying it

I've been holding on to Braveheart and Gladiator (Yes I like movies with gladiators..) on blu ray for when this projector arrived so I'll be checking them out this weekend and playing with the iris to see which setting gives me the right mix of brightness and black levels for movies.

I'd like to thank all of the experts and enthusiasts on this forum. I've read through hundreds of posts for multiple projectors and I couldn't be happier with my final purchase thanks to your debates, advice, and comments.

Thank you
