At sea level, the fan is inaudible at low lamp and a bit more apparent than the RS500 at high lamp with audio volume muted (but essentially still inaudible during movie playback). My NX7 is mounted about 4-5 feet above and 2 feet behind the MLP. Also, power-up to D-ILA screen is under 45 seconds and initial HDMI handshake is under 1 minute with v1.17. My PJ does NOT show evidence of yellowing of white text during credits with DI engaged (in any user mode).

I’ll try unplugging my HDMI cable when I get home after work. Thanks.


I unplugged the HDMI cable and cranked up the PJ. Same thing. This time an improved clocking: 6 mins and 9 secs.

What is the throw range? Isn't there a calculator page somewhere?
Can you use a open hush box in your setup? May be less work in the end, there is also the perk of never buying a mount again. >>> Here is Mine <<<

Does an *open* box really have all that much hush? I assumed I'd have to build something that fully enclosed the projector if I really wanted to quiet it down.

I have a 130" 2.40 1.0 gain screen, projector 15' from screen in a fully light controlled room.

Does this seem reasonable? From the projectorcentral calculator it shows I should be getting 31ftL so how can the figures be so different?

2. Having only had the projector a few days there is some dust build up which seems to be on the inside of the lens but the installer says this is on the outside and normal, no need to clean. Is this correct? Picture below.

Thanks.
I set your screen gain to 0.9. Because manufacturers lie Factor in natural product variance, you're about where I would expect.

Probably not, but it aint doing it any good either. If you can avoid it, leave the burning things out of your theatre.

The problem is a rougher particle could get between the lens cloth and the lens and smudge it, then suddenly you have a smudge.
Now you have to clean it even harder to try to get the smudge out, and then a particle could potentially scratch the lens (or smudge it worse).
Agreed. I cleaned mine once and it left a permanent mark. There is a coating on the lens that you don't want to mess with. Use canned air and blow off the dust regularly. Don't blow on it or you might accidentally spit on it. Seriously.

A plain humidifier is fine. It's just introducing moisture to the air which should not condense on the lens. Anything else, including vape pens, can leave behind a residue. The visible component of vape pens is primary glycerin, not water. It's an oily liquid and possibly worse than some of the other contaminants because it will stick to a surface and then encourage other substances to stick to it.

I think the optimal throw for this projector depending on screen is no more than 20% more than minimal throw distance. I am at about 35%. If I did not have the DCR lens I would want to move it up for brightness.
Agreed, the high lamp is too loud. My proj sits back about 12 ft and I sit at about 10 ft. I won't run it at high lamp unless I move it back much further. Even then I'll still hear it. I'll do a db check on it and report the noise level. I don't live near an airport or train tracks for a reason.

It is a big arse projector. I don't think the size negatively impacts anything though.

What Picture Mode, Color Profile and Gamma mode, MPC settings are you all using for TV content and 4k HDR player content?
Has anyone compared the scaling capability of this projector against their pre or a stand alone scaler like the DVDO?

I never had a problem so much with cheap meters reading lumens over 500+.
I had checked mine against a good meter before, sold the good meter because it was reading roughly the same and didn't need it anymore.

I've tried several cheap meters, the largest error I ever saw was 17% (but then that was around 300 lumen reading), most were under 6% error. The average was at worst 8% I'd say.
I'm sure a cheap meter can give a really bad reading, but it should be fine to give a general idea. Of course it shows LUX (not lumens), but I remember things as lumens...

If something was off 30%, it was broken - dropped - or something, that's way out of spec even for a cheapo meter.

1) We agreed High Lamp is loud, everyone thought that.
2) The difference in picture brightness at my throw between High and Low lamp was small. So I keep it in low.
3) QBF pattern was great across the screen. I think I got a good sample and these are sharp projectors
4) People who had 540's etc clearly said these are much sharper
5) Black not quite as good as the old e-shift but still good
5) DCR lens takes everything to a different level. Brighter and a even better picture.
6) This thing is big, everyone commented on that.

I think the optimal throw for this projector depending on screen is no more than 20% more than minimal throw distance. I am at about 35%. If I did not have the DCR lens I would want to move it up for brightness.
Thanks for this feedback.

I'm quite noise sensitive so I'm going to need a way to hush these things if I end up with this projector (or probably any high end projector, tbh)

Candles and Incense

Well, solving one problem at a time. I received my candle warmer this afternoon. Works pretty damn good. 2 more issues to solve. 1) the slight bend down of the image to lower right corner of the screen. 2) 6 minutes and 9 seconds startup time. Other than that my NX7 is quite impressive. Love it. Regarding #1 the bend down image, in the Installation Mode of Menu, I've tried to make adjustment to the image using the shift and zoom options in LENS CONTROL to no avail. Second to the last option of PINCUSHION remains unhighlighted, as in not available for adjustment. Can someone say how to turn this option on or make it available?

Who else is enjoying 3D? It puts up a beautiful image, i’m sure it’s not as clean as a DLP but the contrast is very nice on it.

You do not want to use pincushion. You need to align the projector lens with the screen. You do that by physically moving the projector. Then you use lens shift to move the image back onto the screen.

Ya my wifes oil diffuser leaves behind residue. Thankfully she rarely uses it anymore except in the bedroom., which is on a different level.

The problem with many of the HTPC/madvr threads is most who use them dont use projectors, as you know the settings are very different for a projector. I think if there was a thread say, "Madvr/Madvr Tone Mapping with JVC NX Proj Set-Up", would be a great help for those with projectors who are new to madvr, Im happy to help....

Unless there is such a thread already for madvr/projs but Ive never seen one. I subscribe to all the related ones here and on other forums, but never seen one for projs.... If its not you maybe someone else may start something, it cant be me even though I have used madvr for years and years with JVCs Im still not qaulified enough to take the lead....
This is an awesome idea! I have been playing with some settings and I am not sure I am getting the best results due to, like you said, settings are quite different for projectors.

We should start a thread for just the RS/NX JVC owners that are going to use either the GTX or RTX cards for MadVR.

I nominate you....lol

Good point about the rated lumens. Weird that the tool has it wrong.

No idea on calibrated lumens....

If you have a chief mount and plan on using the stock screws that come with it, I wouldn't advise it. I picked up some extra screws based on the post in here that says they are too small, and they were totally right. This is the screw that came with my mount dropped in the hole without being tightened, there is maybe 2 or 3 threads that would engage. I replaced with 25MM screws since that is the max length in the manual.

Here ya go:

Testing against a $600 Sekonic meter, I generally found the same the above tester did, but in my testing, the meters were even slightly more accurate (instead of 6%, I usually saw 3% to 4% differences). The cheap meters were all within 8% generally speaking, but the one I kept has a 1% to 3% difference to the $600 Sekonic meter I used.

However, the error of the way people calculate the lumens due to their positioning of the meter with their wrists (and sloppy rounding and adding) can be as much as 20%+...

We should start a thread for just the RS/NX JVC owners that are going to use either the GTX or RTX cards for MadVR.

I nominate you....lol

I absolutely love the 3D on mine! Watched The Walk and Smallfoot the other day &#x1f642;

Other than that my NX7 is quite impressive. Love it. Regarding #1 the bend down image, in the Installation Mode of Menu, I've tried to make adjustment to the image using the shift and zoom options in LENS CONTROL to no avail. Second to the last option of PINCUSHION remains unhighlighted, as in not available for adjustment. Can someone say how to turn this option on or make it available?
Sounds like your projector is twisted to the right. What you need to do, is twist it to the left until the bottom is all square, then use the lens shift to move the image to the right to get it back onto the screen

If someone wants an accurate cheap light meter, the Extech ones on Ebay are pretty good. They were the best one from my own testing, but I only tested 2 (so not a very good sample size).
You can find some of them used on Ebay cheap. For instance, the Extech 401025 retails for $115 new on Amazon ($280 certified), but you can find them used on Ebay under $50.
They will generally read within 3% of a $1000+ meter.

I have 4 different light meters, 2 of them are Extechs. I had more before I sold them back, you can just buy them used, play around with them, then sell them back on Ebay for the same price you paid. I've had about 8 different light meters (over the years), only one expensive one, but didn't need it after all.

Hey guys what the most accurate settings out of the box for HDR? I am using the below and skin tones look too red.

Picture mode : hdr
Color Profile : hdr
Color temp: hdr10
gamma: hdr(pq)
mpc all set to 0
motion only low latency is on


Edit: figured it out, you have to use power law gamma with madvr.
