You got it. That's the exact one I got, it comes in only 1.5 and 3 ft lengths for now.

And the 17 seconds before my screen lowers is a problem. It's the kind of thing that will confuse other family members who want to use the projector but rarely do. You press the power button on the remote and nothing happens for so long that I will be getting called before they realize that it did come up after all.
Haha no worries, just came across a bit rude; I'm sure you were just hyper focused on finding a resolution. I'll time it when I get home on Friday night, to the logo and to displaying image.

I agree 3 minutes is a long time, especially if everyone else is getting under a minute. (Ignorance is bliss... I bet you're a LOT angrier on finding out others' times.) But even at one minute, your wife/kids will start mashing buttons; 2 seconds is the limit of most people's patience. If you're using a 12V trigger to lower the screen, maybe your AVR or AV Pre-Pro could lower the screen instead of the PJ?

Agreed; on my NX9 the contrast default is 0, so I didn't turn that down.

The other setting that might be even more problematic than contrast is sharpness (sharpening or edge enhancement). On the NX series "sharpness" is called MPC (Multiple Pixel Control); I recommend turning that down to 0 (or 1 if that's the lowest) to reduce film grain/sensor noise.

I'll have to track down motion enhance on my PJ and check that out. My film grain noise is a LOT better after removing MPC but still objectionable. (I realize it's normal to have film grain, but it's still excessive and "sparkly".)

Is this a common artifact? Does it have a name? Any thoughts on the possible cause?
As edub90 stated, it has indeed been discussed before. I believe the consensus to date is it's artificially enhanced film grain (whether native to film or added in post to digitally shot footage) by sharpness (edge enhancement). I only really fired up my NX9 this past weekend, so I hadn't seen it myself. I noticed it in certain bright scenes with large areas of the same color, with pretty active movement in the noise like static. And most of the time, no such noise. I turned down my MPC to the minimum setting (0 or 1?), contrast was already at 0 so I left it. It reduced it, but it's still there.

Almost seems like a hardware issue, but it's so intermittent. I wonder if it's a firmware issue, or a panel issue where it freaks out with a certain kind of signal?

Forgot to address your question about 4K/60p 4:4:4 HDR. Scroll to the table at the bottom of this page: http://community.cedia.net/blogs/dav...tes-for-4k-hdr

For 4K/60p/12 bit 4:4:4 HDR, you need 24.06 Gbps and a link speed of 24-48 Gbps, which is easily handled by this cable. And it handles 8K/60p only at 4:2:0 at up to 10 bits, not at 4:2:2 or 4:4:4.

The balun I was recommending, using HDbaseT, does NOT support 10- or 12-bit 4K/60p HDR. But it DOES support 24p and 30p at 10- and 12-bits, which is virtually all the material I watch (film, NTSC TV).

I keep getting the intermittent, way to much clamping down of the DI on my N7. It seems more frequent now. I mentioned this before, but I use Auto2 and aperture at 0. Usually works well, I see the DI clamp just a little bit in darker scenes. This is perfect for my setup. But then, all of a sudden, it clamps down to what seems like maybe -8 or -9, making the picture way to dark, and the text gets dim eller greyish. This happens more frequent, now maybe every other time I use the projector. At first I though this was triggered by something, switching between SDR/HDR maybe, or some procedure when starting or shutting down the projector. But today I saw it triggered during a movie. To get it back to normal Auto-mode, I had to restart the projector. Then played the same scene. All was back to normal, but then a few min later, occured again.

I have tried reflashing firmware, factory reset, changing auto and manual aperture modes. All possible changes of settings. No go. SDR/HDR makes no difference. Using Auto1 or Auto2, no difference. Not sure what to think. I have contacted the distributor / dealer, lets see what they say. Since it is intermittent I am more worried something is wrong with the DI om my unit. Maybe I'll wait for the next firmware and see if it fixes things..

Possibly, but it's hard to tell from those photos. They look a little bit like "mosquito noise"; an artifact that appears on the edges of objects. What I see is a persistent moving static effect on large areas of lighter content, like say the sky or a white suit.

I'll experiment with a few of the settings suggested and see if can capture a representative photo/video.

Really try turning off motion enhance. That should fix it.

RS1000 and RS3000 have been readily available. If you have a RS2000 that may take a little longer then expected. Installing a projector is pretty easy unless you have a weird setup, I would have installed it and replaced it when the new one came in.

@ARROW-AV you probably already noticed this, but I was playing some HDR content off my Nvidia shield (Chilling Adventures of Sabrina) on my NX7 when I noticed DI yellowing. I recalled you had said that for HDR DI shift is more of cyan / blue than Yellow - but I was getting yellow.

So I started playing around with color modes and found that for HDR content using anything other than BT2020 (DCI, HDR) results in Yellow DI. While using BT2020 profile the colors are maintained largely correct.

Could you or anyone else run this experiment and corroborate my findings.

I know that using BT2020 results in about 10% drop in light output ... But for someone looking to use DI - it might be worth using BT2020 vs HDR color profile.

Anyone using DI with aperture at 0? If so, did your projector ever clamp down, to say and eqivalent of manual aperture -8, -9?

Thanks for the info. I am talking with my dealer, giving him as much info as I can. Which firmware are you on? And have you been on other firmwares also?

With the DI engaged on certain movies it would work flawlessly and on others I had a sense that it was clamping down more then it should making the scene to dim like you are experiencing. Unfortunately I believe this is just normal behaviour of the DI and not sure there is much you will be able to do to correct it.

When I first got my X790 I was pretty excited to have the DI and get those fantastic blacks but I came to realize there are certain trade offs to using the DI like the one you have mentioned. I spent way too many hours trying to figure out what was going on with the DI to try to get it to work but in the end was very glad I had the option of turning it off.

Some are ok with the DI and some are not, luckily for me the X790 has fantastic blacks without the DI and turning it off was the best thing I ever did.

Is this happening on HDR and SDR material?

It happens on both SDR and HDR material. I saw it once or twice in my first few hundred hours of usage. But I thought it was triggered by the switch between different modes etc. Yesterday it occurred 1 hour into a movie, just out of the blue. When it occurs, no matter what I play (HDR/SDR) or changes I make, it's there. Only a restart resets the Auto DI to defaults. And clamping from 0 to -8 makes a quite substatial impact in light output. Playing the same exakt scene where it triggered this yesterday, and it did not occur at the same instance. Totally random it seems.

Just got word from the distributor. He talked to the JVC technicians today and they said the new firmware will fix this issue. They didn't know an exact date, but in a few weeks most likely. He asked me if I was ok using the PJ without Auto until then.

Lets hope it does, and also fixes the yellowing at the same time.

tommarra, if you put the "spoiler" tag around a lengthy post (like Arrow-AV's) when you're quoting it, it hides it and avoids cluttering the thread with a lengthy repeat of something that has already been posted. Saves a lot of space on what is becoming a very long thread.

Point taken. On the Tapatalk I didn't even realize this was an issue because the app itself hides the long quote and doesn't have option to add the spoiler tag.

Will be more mindful in future... also edited the post

But then, all of a sudden, it clamps down to what seems like maybe -8 or -9, making the picture way to dark, and the text gets dim eller greyish. This happens more frequent, now maybe every other time I use the projector. At first I though this was triggered by something, switching between SDR/HDR maybe, or some procedure when starting or shutting down the projector. But today I saw it triggered during a movie. To get it back to normal Auto-mode, I had to restart the projector. Then played the same scene. All was back to normal, but then a few min later, occured again.

I have tried reflashing firmware, factory reset, changing auto and manual aperture modes. All possible changes of settings. No go. SDR/HDR makes no difference. Using Auto1 or Auto2, no difference. Not sure what to think. I have contacted the distributor / dealer, lets see what they say. Since it is intermittent I am more worried something is wrong with the DI om my unit. Maybe I'll wait for the next firmware and see if it fixes things..
I think I encountered a variant of this problem on my RS3000. I was watch a SDR movie a couple of days ago an thought the image was very dim and had no pop. So I checked my aperture position and it was the same as I remembers. I switch to another source, I don't remember if it was HDR or not but when I returned back to the SDR movie all was normal again. It is like the aperture forgot where it should be.

I hope you are right that this will be fixed in a firmware update. I would hate to have to check this every time.

No worries. I didn't know about Tapatalk. I'm too much of a Luddite to use that.

Also I have figured out what I like for SDR content as well. I like using the BT.2020 color profile for SDR. Again, personal preference.

Yup I finally pulled the trigger on an nx5. I’m excited to join 4k in my projector.
