I think I will do exactly that.... after the renovation is done I will re-install my Marantz and see how things look on the larger screen.
After visiting a dealer today I am left more confused then ever in some respects.
The NX7 was ceiling mounted and being feed a signal from Shaw cable so I was able to view a wide variety of content and motion for football seemed OK as did gof and basketball.
A couple of days I went to a different dealer that had a NX5 on display but no cable so only input was from a UHD Blu-ray player... the purpose of this visit was to see if vertical black bars where visible on the sides when 16 x 9 content was sent to the projector since it is a native 17 x 9 projector at 4096 x 2160.
I arrived with a 16 x 9 Blu-ray which I know display perfectly on my Elite plasma... we played this disc and it filled the 16 x 9 screen perfectly and I then went up to the screen to see if any black bars where present and I could see none at all which was good at that point. I was told by JVC that a 16 x 9 disc would produce the same result as input from cable so after this test I thought the issue that others have mention is not something to worry about.
This issue is mentioned on page 2 of the following review.

Fast forward to the demo today of the NX7 ... this time my wife is with me... as we are sitting in the room watching various channels to get a feel for how the NX7 will perform with real world cable input I look to see on each sides what appears to be bars outside the image field... I walk up to the screen and sure enough the bars are about 3 inches wide and very distinctive.... Actually could put my hand and fingers in the way of the light path and you see a "puppet show" on the wall.
My Wife then says... "I thought you said you checked this and this was not a problem?.... followed up with of course the required advise... "You might need to get your eyes checked!"
"Consumer video content adheres to a 16:9 standard, which 1080p Blu-ray, UHD Blu-ray, and broadcast HDTV follows. The issue is that the RS2000 uses true 4K 4096 by 2160 panels, not UHD 3840 by 2160 panels, making the native image 1.89:1. This means that any consumer video format played through the RS2000 will show black bars on the sides. ".... from the review in quotes.
I can not live with bars outside the image so the JVC NX7 will not work for me or any 4096 x 2160 projector since it appears that I am a "Consumer Video Content" guy and need 16 x 9 native projector.
Which at the moment leaves me with two choices.... my Marantz 15-S1 or the BenQ HT 9060 with is native 16 x 9.
Been quite a couple of days and always "special" to have a surprise with your Wife on hand to add the required commentary!
