JVC NX5/RS1000 Owner Thread

For discussion about all things JVC NX5 projector talk.

So I am having issues getting the JVC NX5 to align properly with my 16x9 100 inch diagonal screen.
I did not have this issue with my prior Pani projector. The projector is mounted on the ceiling and hangs the same distance as the old Pani did.

JVC NX5 specs are:
Lens shift function+/-80% vertical & +/-34% horizontal, motorized in 16:9 aspect mode

Panasonic PT AE7000U specs are:

Optical axis shift*sup7/sup	Vertical: ±100%, horizontal: ±26%

So the question is, how much lower in inches does my projector have to hang in order to properly fit the screen. The issue is I need the picture lower. It appears there is a 20% vertical distance difference. What does 20% equate to in inches?

Have you loaded it into this calculator: https://www.projectorcentral.com/projection-calculator-pro.cfm

according to the information my projector lense can be 39 inches above screen center and still properly center. So I guess i need to measure lense to screen center and subtract 39 inches. That should give me the distance I need to lower my lense. I never noticed the inch conversion for lense shift on that site before. I checked it before buying the projector to ensure it would have proper throw distance based on my small room and 100 inch screen. Thanks for pointing that out Sonnie.

So after doing my calculation, not good at math, it appears the difference between 100% and 80% vertical shift is 6 inches. So my projector which hangs at 3 inches needs to now hang at 9 inches to properly align on my screen.

You need that shelf like I built... make it as low as you like.

How do you know when there is a firmware update for your JVC projector? Is there a notification process?

I did the firmware update too 3.10 on my RS1000 today and then Setup Frame Adapt HDR.
HDMI level Auto
HDR Processing Frame -Frame

Then I put THE MEG UHD in the Pani UB9000 to see what magic Frame Adapt HDR does.
I originally watched this movie with my projector setup according to the original joint directions between JVC and Panasonic prior to the new firmware.
In that case I found the film to be very bright and lots of white...washing the image out in a lot of the daytime on the water film scenes. Particularly the time stamp 010915 in which the bald guy is standing on the overturned boat and the sun is glaring down on him. In this scene it was so washed out you could not even see the outline of the top of his head. Now watching it with HDR Frame Adapt his head is clearly and very nicely outlined. Its sunny out in the scene but the picture is not washed out. This example for me shows very clearly what magic HDR Frame Adapt can do. Sorry for any non technically terms or improper video verbage as I am not very technically inclined in these areas. But I can say I can notice when a picture is better.
