When I went to JVC 4K from a Epson 1080p projector I upgraded all my HDMI to Monoprice Certified Premium High Speed HDMI cables for my interconnects. I use a HTPC with Nvidia GPU. Haven't had any problems, but I know 4K is real touchy. I'd even upgrade my game units HDMI cables to certified cables, if it were me. I don't game so only take that as a suggestion. Good Luck.

You could also try using the other HDMI input on the JVC to see if that changes anything.

Yah I'm going to. I know there's cables that just don't measure up. I'm just confused why the Scorpio never has an issue and the PS4 does?? The HTPC I get because I run 4K/60 at Ultra settings so I can see where I'd get bandwidth issues. Anyway I figure as long as this works I'll use the fiber cables on everything. I'm gonna try it this weekend and report back.

Since the RS400, 500 and 600 the JVC's have been full 18Gbps HDMI. Baring a defective projector and I don't think yours is defective, if it is dropping out, then you need to look at the other items in the chain, not the projector. Take a certified HDMI cable and connect a source like a Roku and send 4K 60P direct to the projector. If it works without issue, then you have just proven it is not the projector. If you use an HTPC and have issues, it could be a setting problem with the PC. That is why I would test with a source device like a UHD BD player and Roku or Apple TV.

Yah I know they are and that's one of the reasons I went with the JVC. It's also why the cables are my main suspect. Don't have a UHD player, Roku, or Apple TV. That's what the HTPC and Scorpio are for. Like I said I have no issues with the Scorpio which is why I think it's the cables and not the pj, because only when I'm pushing 4K games at ultra settings on the PC does it trip it up, and the PS4 cable is a cheaper blue one so I'm pretty sure that's it. I'll find out for sure tonight or tomorrow.

Just purchased a brand new X790R and have a couple of questions in hopes someone can guide me to where I can get some of my answers:


1. I'm looking for some settings to try with 4K content...not sure where to find some of these settings.
2. Need to find 3D glasses and am unsure what I need as it's been too long and am out of touch since my last purchase of 3D glasses (2012)


I run all my movies via HTPC (MPC-HC and MADVR) Videocard is a Nvidia 1070Ti



I'm already enjoying some viewing already and am quite pleased with what I see.


Much thanks in advance
Kind regards,

The first post of this thread has some recommended settings.
My signature also contains some links for optimizing the HDR settings.

Thank you kindly for your feedback.
On the first page, 1st post all I see is settings for the X990. Did I miss something?


thanks

Identical settings apply to the X970 and X990. The X770 and X790 also use the similar settings.

I wonder if the Philips PTA02 Glasses are compatible. I saw one poster recommend them, and they are pretty cheap. However, you have to make sure screen polarity is not an issue for you (you could lose up to 50% of your lumens) and these are IR, which are not as good as RF glasses.

Have the strangest issue that I seemed to workaround, but just thought I'd share in case anyone else has run into the same thing.

I have my RS540 getting its sources fed through my Denon 3500H.

All my sources (Shield, Cable, UHD Bluray, PS4 Pro) work fine, but ran into an issue with my Xbox One X where it wouldn't output when I set the console to 4K UHD resolution. In the temporary screen where it asks you if you'd like to keep the changes after toggling the resolution, I would get some static on the screen and it would eventually crap out and say my TV is having issues with 4K.

I switched to 1080p which got rid of the issue. Allow 4k is also checked off; if I start a 4K-capable game, the RS540 toggles the resolution appropriately, and I'm able to get signal and have the game outputted at 4K+HDR.

In summary - my Xbox One X dashboard only displays if I set the resolution to 1080p, but when 4K games are loaded the RS540 changes the resolution and the game works fine.

I can't believe I'm saying this about HDMI cables, but we bought a $350 Audioquest Cinnamon 33" cable and it actually fixed the problem. The previous HDMI are all "certified" HDMI cables from Blue Jeans Cable (the 35" one) and also the optical fiber one from Ruipro (33"), which technically should not have any problems. But I think the longer the cable runs the more important the quality of cables are, to get a stable image.

Odd thing is my PS4 Pro did it the other day as soon as I turned it on yet my Xbox Scorpio doesn't?? The screen went black instantly. Idk it's a pita for sure though. Should be able to double check though I realize that doesn't help you now. Also my artifacts are a bunch of little blocks and it's always on the right side for some reason. Almost like it's trying to render the image.
I have problems on my Xbox one X as well, and it's the same problem. I don't know about the PS4 pro since that's connected to my LG OLED. Perhaps the Xbox One X is more sensitive to lower bandwidth issues?

I'm using pretty much exactly the same setup, Xbox One X --> Denon 3400H --> RS540, and have practically the same issue. It usually happens in the dashboard screen as well, and it goes away if I change the resolution to 1080p. If you're running a 30+ inch HDMI cable, I would seriously consider "upgrading" to a better cable, as that fixed my problem (alternatively you can go for a shorter distance). We got the Audioquest Cinnamon cable from Best Buy, which absurdly expensive at $350, but nontheless fixed an issue even the RUIPRO optical HDMI cable didn't fix. In the end, I figured out it wasn't my projector being defective, it was a HDMI cable problem.

Any chance you have inches confused with feet in this post? The cable run to my projector uses a 30 FOOT cable. A 33" cable is less than 3 feet, which is a pretty small run in my opinion.

This is the cable I use with no issues:

Monoprice SlimRun AV HDR High Speed Cable for HDMI-Enabled Devices - 4K @ 60Hz, HDR, 18Gbps, Fiber Optic, AOC, YUV 4:4:4, 30ft, Black 1 $159.99 $159.99

It is an active cable, which means you need to pay VERY careful attention when doing the cable run as the signal flows in ONE direction only and you have to get it right.

Yah I was gonna post that I swapped out the cables for a $40 fiber cable from Amazon(it was on a lightning deal coincidentally) and even though the other one was rated for 18gps this one seems to work. I played for around 3hrs or so and had no issues. Usually it'd happen within minutes or no more than an hour into playing so as of now the fiber cable worked. Interestingly the cable from the HTPC to the receiver is not fiber just another hi-speed rated cable. I did bypass my HDMI wall plate though. I had a 15ft cable going to the wall plate, which was also hi-speed rated, and then another 6ft cable from the wall plate to the JVC. This is a 30ft fiber cable that I went straight to the JVC with just to see if it would work with a "direct" connection and of course eliminate the other variables and so far so good. I'm happy for now. Interesting your fiber cable didn't work though. Like you said technically it *shoould*. Mine is a 30ft and your run is over that correct? I guess on those long runs it does make a difference. Electronics nowadays drive me crazy smh.

I have another fiber cable I can try with the PS4 and another hi-speed cable on the way from the same company I'm using for my HTPC-to-receiver connection. I'll try them both out but I'm pretty sure it was the receiver-to-JVC connection..

If I recall correctly, yes. With this Iris setting, and Profile off, with the filter in the path, I measured 100 Nits on my 110” 1.78:1 Stewart StudioTek 130 (1.3 gain) screen.

I posted a settings document spreadsheet that you can find by searching for my posts, if interested.

Wait, fiber optic HDMI cables are not bidirectional? You mean you can only plug into it one way, from a source to an output?

And yes, I meant feet not inches.

I swapped it with a 20 feet version of the same cable, and it worked fine. I’m wondering why doesn’t the 35 feet version work. I read somewhere there’s a 5v plug you can use with the HDMI to the receiver that might help, as it used more power to travel longer distances?

Should be able to double check though I realize that doesn't help you now. Also my artifacts are a bunch of little blocks and it's always on the right side for some reason. Almost like it's trying to render the image.
I have problems on my Xbox one X as well, and it's the same problem. I don't know about the PS4 pro since that's connected to my LG OLED. Perhaps the Xbox One X is more sensitive to lower bandwidth issues?

I have my RS540 getting its sources fed through my Denon 3500H.

All my sources (Shield, Cable, UHD Bluray, PS4 Pro) work fine, but ran into an issue with my Xbox One X where it wouldn't output when I set the console to 4K UHD resolution. In the temporary screen where it asks you if you'd like to keep the changes after toggling the resolution, I would get some static on the screen and it would eventually crap out and say my TV is having issues with 4K.

I switched to 1080p which got rid of the issue. Allow 4k is also checked off; if I start a 4K-capable game, the RS540 toggles the resolution appropriately, and I'm able to get signal and have the game outputted at 4K+HDR.

In summary - my Xbox One X dashboard only displays if I set the resolution to 1080p, but when 4K games are loaded the RS540 changes the resolution and the game works fine.
I'm using pretty much exactly the same setup, Xbox One X --> Denon 3400H --> RS540, and have practically the same issue. It usually happens in the dashboard screen as well, and it goes away if I change the resolution to 1080p. If you're running a 30+ inch HDMI cable, I would seriously consider "upgrading" to a better cable, as that fixed my problem (alternatively you can go for a shorter distance). We got the Audioquest Cinnamon cable from Best Buy, which absurdly expensive at $350, but nontheless fixed an issue even the RUIPRO optical HDMI cable didn't fix. In the end, I figured out it wasn't my projector being defective, it was a HDMI cable problem.
Thanks - since I’m able to still play the actual games in 4K, I can live with the dashboard at 1080p.

It’s the strangest thing; sometimes I’m able to toggle to 4K in the dashboard, but when I go to load a game, I just get a black screen/no signal after the initial game splash screen. I hear audio, just no video.

1080p dashboard, all 4K games work.

See mine did the exact same thing. Screen would go black and I'd have no video but it wasn't right away like yours. I'd play for at least a couple minutes before it would do it and some nights it'd be hours which is why even after 3hrs I'm not convinced......mostly cuz I have s*** luck.

I thought maybe if I kept my desktop at 4K resolution it would help thinking maybe it was a handshake issue but that didn't help either. Only switching back to 1080p made it work so that's why I was pretty sure the cable couldn't handle the data. Though I have no idea why @Solarium had issues with his 35ft cable? Though I also didn't realize fiber optic HDMI's were directional so maybe he just hooked it up in the wrong direction and I must've lucked out hooking mine up.

That is correct. Active fiber cables are UNI-DIRECTIONAL. You have to look at what is printed on the ends of each connector. One end should be labled source and one end should be labeled destination (or some similiar labeling) so you know which end plugs in where.

If you reverse the cable, I'm not sure it will work at all, but it certainly won't work well.

I've posted about this little detail in other places and it is a farily common mistake that people can make with these cables if you have not used them before.

I use a 23 gauge copper cable, 20 feet in length, from the monoprice certified premium line. I also get blank screens from time to time and it can be a bear getting the picture back. It's as though it will not handshake again, even when turning off sources and swapping inputs and back. I don't want to buy another cable yet as I have not finalized positioning for equipment. Is there a trick to getting the projector to resynch, short of turning it off and back on?

Switching inputs and then back should cause a re-sync.

Not that I know of other than switching inputs like @giomania suggested. Sometimes my picture would stay black for a couple seconds and sometimes it'd be closer to 10 seconds but it would always come back. It was random but only with the signal being 4k/60. As soon as I go back to 1080p it's fine. That was the only thing that worked for me. Are your issues with 4K too?

This cable seemed to solve my issue though. Again I only used it for 3hrs the other night but it definitely would've done it in that time so I'm pretty hopeful that was it. This is the cable:

https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I have a copper cable going to an HDMI wall plate, and than another cable from the plate to the projector. All were "high-speed" rated. I ran that fiber cable straight from the receiver to the projector and so far so good. Idk if that'll solve your issue but it worked for me and others as well. Also I did double check and by dumb luck I did have the direction correct on my fiber cable.

Perhaps my issue is with the Oppo 203, but I have tried powercycling that, too, with no luck. If I can manage to blindly get the Oppo to start playing material from the disc player that is a different native format, it will cause the projector to synch to a new signal type, which wakes things back up, then I can go back to what I was doing.

Check the output signal setting on the OPPO. Also try starting up the OPPO without a disc in the player, which causes it to go to the menu screen vice the disc menu.

So you are saying it was not the cables then? Did you end up taking that expensive cable back and getting a different one?

Exchange unit was received today and the failed unit is already in route back to them. I am not the original owner of the projector so it was a tiny hassle. JVC was able to trace that it was bought from an authorized dealer. I had to get the original sales receipt. Earlier in the thread someone mentioned, no original receipt, no sale. Pretty good advice.

Very please with JVC. They could of walked away from this as I was not the original owner.

Thanks again Mike for the responses.

Quick question. I seem to remember reading something about NOT shutting this projector down in HDR mode for some reason. Can someone remind me why?

I was just finishing Alita Battle Angel(at the credits) and we had a power outage for like one second. Everything rebooted fine and I don't seem to be having any problems but I remember reading something and can't remember what was said.

1) JVC RS540, Yamaha CX-A5100, Outlaw Audio 7700 & 7140, Wharfedale Jade 7's series speakers, RSL C34e(Atmos)
2) LG OLED65B6, Integra DRC-R1, Emotiva XPA9, Klipsch RP8000F, Klipsch RP404C, Klipsch RP500SA, Klipsch RP140D

That would probably be me.

At least on my unit, if you have very different settings for HDR and SDR iris (aperture) - ie iris more open for HDR - when you boot up having shut down previously in HDR, with an SDR source playing, it won't reset the lamp iris back to the proper SDR position. So when you next go into HDR mode it tries to drive the iris back to more open than the mechanism allows, and grinds. It appears to me to be a bug in the way auto HDR mode is implemented.

I've not have much luck getting anyone else to try it out as it makes a horrid gear grinding noise when you do it, and there were a spate of iris mech failures on these units, so I don't think folk are keen to torture their units...!

If you have to be safe next time you power it on you'd want to ensure an HDR source is playing before you power on. That way all the states should be aligned and when you stop playback and drop back to SDR mode everything should be back to normal.

Hi all,
I have not found any responses to this question and I have the exact question. Would like to be able to send a "custom mask" command directly to the projector.... Has anyone found a way to do that?
Thanks in advance,

Thanks, Yup that was what I remember reading. It didn't effect me, that I can tell. I had my projector calibrated by Chadb and it powered back on to a SDR signal from the AppleTV home screen when it came back on. It seems to be working just the way it was before.
