You're not going to get any joy whatsoever. The dead pixel tolerance that they've put in the manual is a complete joke (>24 dead pixels allowable, 8 for each colour) and so will anything else they actually commit to.
Someone should take them to task on the dynamic contrast numbers as I'm sure it is actually impossible to meet them with currently shipping firmware.
Maybe we could start a JVC documentation thread, where links quotes with relevant specs and tolerances from JVC could be collected.
The RS2000 i shipped back was replaced by JVC, but they did not specify why.
I would like another N7 / RS2000, but this time i want some tolerances on the most important parameters like color uniformity with closed iris, contrast uniformity/ bright corners, convergence.
It seems that bright corners are not tolerated in the US, and a valid return reason.
Ill buy from Ebay as that secure my rights if the projector dont deliver acording to specs, i can return it, not as described, without having to argue with the local JVC dealer, and typical JVC reply ( Ship it back and we will evaluate the unit, if we find it within tolerances you will be charged for shipping and testing)
What i seen the reviews is useless as the unit variations can be 50% or more on some parameters.
Anyone wanting a new JVC N series ill recommend to go look at it in the store, get a demo of the specifik projector your buying, not just the usual demo and take a new in the box off the shelf, or do as i do buy on Ebay, pay with paypal, and use a week or 2 to check out the projector, and sende it back if you fin it a bad sample, look for bright corners and color uniformity with closed iris, there will be some on all units, i had dE12 variation from center to 2 feet right on my 110" peak contrast on minimum zoom fully closed iris, and BT2020 filter on was 75000:1 in the center and around 18000:1 in the brightest corner.
The BT2020 filter do up the contrast, but since the N5 dont have the filter, it makes no sense to measure these models with filter on, the contrast spec should be delivered in minimum zoom fully closed iris, and not only in the center, ill say a 25% contrast drop in the corner is hard to see, so should be tolerated, much above that i would change the unit.
If there is doubt about the tolerances, and you feel its not performing to your expectations, ill think that returning a unit saying its not delivering lightoutput acording to specs will be fair, as i have not seen or heard about any N series capable or close to capable to deliver the lightoutput promised.
