You have any shorter known Premium certified cables around the house, try that out real quick if your devises or projector are easy to get to and move around........

No need to spend any more money than you absolutely have to.

If it doesnt work you can always return it and get one of those "premium certified cables"

Given how many stories I've seen like yours it seems like 25' is just at the practical limit for effective transmission of 4K and variations in cable manufacture, source/sink device, bend radius, or RF environment appear to be enough to cause a failure. My run is just over 30 feet so I couldn't have used a 25' certified cable anyway, but I think I'd use fiber regardless for any run over 15-20' just for peace of mind. The cost is a rounding error compared to everything else in the room.

I think you meant 4K60 4:2:2 HDR10. 4K60 4:4:4 is limited to 8-bit so not appropriate for HDR. 4K60 4:4:4 10-bit is not supported in HDMI 2.0 as it exceeds 18Gbps and no JVC projector will accept it.

Because it's been tested along with lots of competing brands by some of the guru's around here and it, along with the Ruipro, were the only two cables that passed all tests for longer runs.

I agree that if you want to try find a cheaper cable that works, that's fine. And if a cheaper one doesn't work, you can always return it and try another. For me, if I'm buying a $5,000+ projector and have to deal with sync times, DI, tone mapping, changing metadata on HDR discs, calibration issues, issues with various streaming sources, and all the things that go into this hobby now with these complicated projectors, the last thing I want to be fiddling with and changing out over and over and playing guessing games with, is my HDMI cable. I want to eliminate as best I can one potentially problematic variable. But that's just me, and I fully understand why other people might want to try other alternatives, especially for the 25 feet distance.

I have a 50 foot monoprice fibre optic cable. There are 2 reason I bought it:

1) it works!
2) it is easy to snake through an in ceiling conduit

I wonder if it's my screen material that may be causing the issue. I will take a picture of it this weekend. I have a grey 1.3 gain ambient light rejecting screen from Elunevision called Aurora. I also have the regular 1.0 white screen from them with no sparkling. Not sure if I should switch the screens. I do love the black level performance of the grey Aurora, but It leaves me wondering if I'm leaving anything on the table by using that screen.
Anyone using MadVR will have some sort of PC connected to their projector.
You don't say how old you laptop is or what kind of video card it has, but generally you right click on the desk top and open "settings" for you video card.
There under "resolution" you can change the chroma subsampling, and resolution _ if available.

Now you are saying you do not have that issue while using MadVR? And what projector are you using MadVR with at this moment and testing out that scene?

Correct, if setup with the proper nits value that the projector is outputting then MadVR handles scaling everything appropriately so I’m not having any issues with scenes like that. This is on my old projector I haven’t sold yet, a Sony 675ES.
Looks like I need to get myself an RTX 2060 so I can try out this MadVR. Too bad they are $500 in Canada!

How exactly do you tell how many gpps you are getting in your system?

All I can see is that I'm getting 12 bit.

Initial impressions were that it's like I went from your standard theater (my Panasonic AE8000U) to a Dolby Cinema (a good one).

After the movie, I tried to watch a few short clips of 4K material, but ran into some problems.

When I played 4K files on my Zappiti One, ufortunately, I saw that the projector was being fed 1080p. Went through settings on the Zappiti and couldn't find anything. On the "TV System" setting, I had selected auto, but of the other selections, the highest it went to was 1080p, there was no 4K resolution listed.

Then I went to my Xbox One S, and it immediately said I had a 4K display and asked if I wanted to change the resolution. I clicked yes, and then the screen went blank and said no signal. I had to turn off my receiver (Yamaha A3050) and turn it back on to get a picture again - and that was the Xbox saying that the attempt didn't work. I checked the details screen, and it said my TV system was capable of 4K, but then said I wasn't able to do some other things. I went through some of the troubleshooting steps on the Xbox and got a few more of the items checked off, but most still said they wouldn't work. After this, I did get a 4K signal when watching Netflix, however, it was still not HDR. Zappiti is still just doing 1080p.

I'm not sure if I'm just not having the settings right, or if there is something wrong with 1 or more of my devices (or cables - Monoprice redmere). Any settings on the JVC (or the other devices) I should look at as a possible culprit?

Here's the initial detail on the Xbox:



Edit: Also, I did try putting the lamp in high mode before shutting down for the night, and the fan was quite loud.
I had this same issue with mine on my Denon. I had to set the HDMI 4k settings to enhanced on my receiver. Fixed the issue for me!

Got my NX7 last week and really been working on trying to adjust the picture, but I'm struggling. I probably dont know enough about what each setting does to really be using it correctly. Is there a consolidated list of recommended settings to really get the best performance out of this unit? The picture seems a bit dark sometimes when watching 4k discs.

Is there a recommendation on the low latency or CMD stuff? I like the picture to look smooth....

I have the aperture set to Auto 1 as well.

Thanks and sorry if it's a redundant question. This post has really exploded and gone so many directions.

Screen is 1.1 gain and room is completely light controlled, but we do like a little light when playing games or just watching regular TV. Love it blacked out for movies.

If you are using auto tone mapping on a large screen you should probably bump up the mapping level until the picture is bright enough, I found setting mine to +3 and then increasing the contrast to 7 and the decreasing the brightness to -3 got me a decent picture with HDR, the contrast and mapping level got the picture bright enough and the -3 brightness got the black floor low enough to have a full fade to black with the DI engaged.

No need to spend any more money than you absolutely have to.

If it doesnt work you can always return it and get one of those "premium certified cables"
I have the Amazon 25FT cable, it was artefacting at 4K60. Getting a premium certified mono priced cable solved the problem.

Which version of blade runner 2049? I have the Sony version, which is mastered for a much brighter nit monitor than the USA WB version that most of you probably have. This has never looked good before the last two weeks version of madVR. It was definitely watchable before, but now it actually impresses as if I'm seeing HDR for the first time.

I wonder if it's my screen material that may be causing the issue. I will take a picture of it this weekend. I have a grey 1.3 gain ambient light rejecting screen from Elunevision called Aurora. I also have the regular 1.0 white screen from them with no sparkling. Not sure if I should switch the screens. I do love the black level performance of the grey Aurora, but It leaves me wondering if I'm leaving anything on the table by using that screen.
It's very likely your laptop sucks at sending a true 4K desktop.
Try the following things to clear up text as a starting point:

1) Go to display properties in the graphics card and set up 4k / 60 / RGB 8 bit. None of this yuv stuff.
2) Go to display settings in windows, and set dpi scaling to 100% not 150% not 225% etc. This will make the text small, but it will be non-scaled and should be crisp and sharp.
