(so he surmised it only happened when the TV was running at certain frequencies the EMI intersected w/ from the speaker magnets... it's all above my pay grade but trying to report what I think I recall from many years ago).

What I still find interesting is you've called out the Roku a couple times (does this only seem to happen when the Roku is powered on and is it possible it has a defect with the WiFi signal being sent out or something?? . . . and you're sure your HDMI is not run thru/touching something it shouldn't be... like perhaps the same power plug running to the Roku perhaps... or the Roku's power supply is touching something in your rack which is also touching the HDMI out to the PJ etc...?? . . . deeep thoughts... by Jack Handy! )
Ah - he has a PLASMA, gotcha. That's where I got confused. I thought he had a JVC.

Yea its weird. If you read jarrod's report it is pretty clear cut that just the presence of the speakers caused his issue. And when he changed to shielded speakers it was fine. My pj is surround by 4 ceiling speakers too. Fortunately my issue is rather rare - happens maybe once every 3-4 weeks with every day use. Only had seen it when switching from the UB900 4K output to Comcast 1080p. But with some testing I was doing with the Linker I had my Roku Ultra connected directly to the pj (with Linker in the middle) and it triggered about 50% of the time or more when switching to HDR or when switching out of HDR. Fortunately for now I don't like HDR with the Roku - too dark. I should probably try it again some time with the Linker out of the chain, tho I don't think its playing a part but you never know.

Thanks. Let's dissect the bright curve for a moment and compare to what I am using currently, which I like but may limit my HDR effect. Keep in mind please I only have 45 nits to work with.

OK so my current curve is 200-50-200-3000. Comparing that to @fingersdlp Bright curve, I have the same 4:1 ratio. He has 300 for third param, so he is leaving more brightness for HDR effects, and let's ignore the rest of the numbers since I don't think they matter much at all (I've done A/B testing with 1, 0.7, 0.5, 0.3 for the 3rd to last param, for instance, and can't spot any differences - tho that may be unique to m low nit situation.

What's the significance with the 4:1 ratio? And what do I get back by dropping the hard clip point front 3000 to 2000 let's say - more brightness? So maybe I should try 200-50-300-2000?

Also if I set my hard clip at say 2000, does that mean I should set my HDR bright clipping pattern (Ray's patterns) to clip at 2000 instead of 4000?

Thanks!

How did you go about measuring that - CalMAN? Why measure to 255 instead of 235?



Great, glad to hear I was not imagining this. My custom curve (with hardclip at 3000, not 4000) behaves like the SDR slider at -6. If I lower contrast on my custom curve about 7 clicks than it doesn't crush like Panasonic slider at -12.

I like my HDR curve in some ways better. Like it is the best shadow detail in the blacks I have every seen in a projector. Probably a coincidence because I don't think there is anything in particular about these custom curves (200-50-200-3000-1-1-1) that would make it superior over say a BT1886 curve for shadow detail? Anyway I need to manual adjust my SDR gamma via the jvc tool to get it perfect so I can see if its crushing near 7.5%.



Thanks for the info! So how do you use that cloth? Do they make that stuff in black? It wouldn't look too pretty, unless a smallish piece could be used...

Also can you please elaborate on HOW he wound up figuring out that it is electromagnetic in nature, which led him to even try that shielding in the first place? I would have never of thought to try it, until I read @jarrod1937 findings.

@jarrod1937 - interesting info from krichter1, yes? Any thoughts for how I could try using the material, even if just in a test case temporarily to see if I am no longer able to reproduce it with the material being used? Where would I put it? Any idea where the e-shift electronics are within the case so I could perhaps concentrate it in that area?



Why do you say that? Based on jarrod1937's testing it is very reasonable to assume that it is electromagnetic waves causing the issue. Then Kevin says he had a friend with a JVC that had the same issue, and solved it with electromagnetic shielding. Are you thinking that is just a coincidence?
Because the problem is not caused by electromagnet waves.

I could try raising that to soft clip to 400. In doing so that would make room for more HDR effects (?), but at the expense of what? Lower overall brightness?

Thanks!
For a 200-50-xxx curve, (or 4:1 peak to ref white ratio), if the soft roll off is set to 400, then at 400 nit input, you are at the projector max output, and everything above 400 nit input is clipped.

Edit: This is a mistake. At 400 nit input, you would only be 100 nit output, and would have 100 NITs left for rolloff


I purposely set the soft roll off to 200, because that would be 50% peak, allowing the other 50% for the roll off.

Edit: this is also in error, at 200 nit input, the output would only be 50 nit out, leaving 150 nit for roll off.

You could try 200-50-300,... if you want to follow the ST2084 curve shape longer.

While I don't know for sure, I suspect that a high ratio is more important than the rolloff start point in determining the HDR look. But, raw NITs is likely the most important ingredient.

Electromagnetic waves is not causing the issue. Did you see his post, where Jarrad could not replicate the issue. https://www.avsforum.com/forum/24-dig...l#post51221665

I have the same issue, intermittently. He was not having any problems with the speakers themselves or their output, just the effect it was having on the JVC HDMI sync.
He just thought the problem was electromagnetic, it wasn't. Did you see where he said he could not replicate the issue.

I think Rak may have answered your questions in post 22209 and yes set your white clipping patter to 2000 if that's what's used in your curve.

I am not saying shield electromagnetic waves is snake oil. I am saying it is not needed, because the issue is not caused by electromagnet waves, from speakers that are 6' away from the projector. So he would just be wasting his time.

Need help from owners with normal projector rigs to help test 2 new sets of PQ curves. The first set has 3 curves for 100in Wide Screens with Ypeaks around 90nits. The second set has 3 curves for screen widths of 120 inches with Ypeaks around 70nits. All curves have passed all tests on 104" wide screens. The curves for 120" wide screens are still experimental (95% complete), but are good enough for others to play with.

The curves in each set will vary in brightness, contrast and saturation. Just load the three curves (C1PQ, C2PQ and C3PQ) into their respective JVC Custom Gamma Slots (Custom1, Custom2 and Custom3), watch 4K HDR movies and pick the curve you like best based on personal preferences. NOTE: if the picture is too dark, you are in GammaD mode ... switch to Custom1,2 or 3 (Import must be selected rather than Normal).

In addition,

1. LAman Adjustable Curves: These curves were designed from the bottom up to be adjustable with LAman (0,-4,-8,-12, ect) ... adjust these curves with LAman according to your personal preferences. Yes, these curves are bright enough to use LAman for certain 4K HDR movies.

2. Set CR=0 and BR=0: All the brightness, contrast and saturation levels are built into the curves ... this means you'll set your projector to CR=0 and BR=0 for all curves.

3. Large Y5% Color Space: The Y5% color space size for C2PQ and C3PQ are much larger than what you've experienced to date. This means brighter and more colorful shadow image detail.

4. All Curves Designed for Projectors not Flat Panels: These curves were designed for normal projector rigs, not flat panel displays. Used calMAN and LightSpace cms to accomplish this. These curves fix the root cause of GammaD being too dark. Will forward to JVC Japan once enough JVC owners buy in.

If you have a 95% rig and are interested in testing these curves and providing feedback, pls PM me and I'll email the PQ set that best matches your rig and your HT ambient conditions. All that is being asked is to identify your rig by filling out the attached spreadsheet, have a 4K HDR blu ray player (UB900 or OPPO203 or K8500 or Phillips xyz ... but, no 4K HDR streaming until later), have the 4K HDR movies below and go to the specific chapter and time stamp and send feedback to which curve (C1PQ, C2PQ or C3PQ) looks best per scene and why.

4K HDR Movies:

1. Batman v Superman
2. Gods of Egypt
3. Ice Age Collision Course
4. Jupiter Ascending
5. Kingsman
6. Star Trek Beyond
7. Suicide Squad

Thx!

Oops. You are right. At 200 nit input, it would be 50 nit output. And at 400 nit input, it would be 100 nit output. (4:1).

So for Ric, I would try 200-50-400... or even 200-50-600...

Thanks Carbon! Wholly crap! More testing...I now have 100 hours on my pj and have only watched 2 movies just curious, have you tried Arve's tool? Any feedback? Appreciate what you are offering us here...what really surprise me is how poor native hdr is on the 550,750,950 series with little response from jvc...and folks on here have proven it can be much better!

ThNks Rak, r u able to edit the original post, so folks are not confused? Your call...thanks man

Thanks, it is fortunate that our setups are similar enough that these work for you. I saw an earlier post you had 120" diagonal screen, 1.0 gain, x950, 14 foot throw, bat cave. I have about 119", 1.2 gain (maybe) but a longer throw of 18 feet. I suspect we must have similar brightness off the screen. That bright one I use just for titles like Star Trek Beyond and Arrival. If I use it on higher graded titles it is too much.

Awesome!! Yes very similar setups indeed!! I really like having 3 curbs I can just hit the gamma button for and switch...tempted to buy a Linker for the DI but it's $300 smacks by the time it makes it to Canada...I see Carbon has some new tests...not sure how they differ...I may be all tested out for today...

I think CFP asked if you wanted to test the curves, you should PM him with your set up details, and he will send you the set that he thinks is most appropriate.

I am currently using integral with panasonic ub900 sdr bt.2020. If I were to purchase the linker to enable di in hdr and import some custom curves (carbon) or create my own wirh arve tool would I need integral as well or could i pull it out of the system?

Haven't tried arve's tool. Spent over 300 bulb hrs analyzing and creating custom GammaD curves. Started using calMAN 2 wks ago and found 30% of their PQ curve to be very useful. I found their workflow to be extremely useful and used Light Space to create the remaining 70% of the PQ curve ... uniquely tuned for projectors.


Recently created a custom GammaD(000) curve ... the curve that comes out of autocal ... and modified it to show JVC Japan exactly where the root cause of the GammaD brightness item is. They will instantly know its own of their curves ... in fact, 70% of JVC GammaD curve is perfect, it's the remaining 30% or so that needs to be fixed ... and it can't be done by Roll-Off. lol.


If enough owners see this, then these curves will be forwarded to JVC USA, then to JVC Japan. Right now JVC USA still thinks 200nits can be easily attain with projectors and is needed for HDR.


JVC owners can easily show JVC USA and Japan that their 95% rigs can produce a great 4K HDR picture can with a Ypeak range from 70nits to 105 nits with screen width sizes varying from 90 - 120 inchs. The only difference is the x10 clip point range is between 820 nits (for 120 inch wide scrns) to 1100nits (100 inch wide screens). These curves were tested on 104" wide FireHawk SST screen (gain 1.1, 16ft throw, 11 ft view) and 120 inch wide da lite Class C White Screen (>=1.0 gain, 16' throw, 11' view) with excellent results. The Alens was not used for any of the curves being offered for analysis ... so it other owners 95% rigs should have similar results.






Keep moving it forward with HDR.

Even after reloading FW 19, I had problems with purple tint which is supposed to be fixed with 19a, not INTRODUCED. Since I was handling the hardware, I may have inadvertently moved a slider or something. I hope that's all it is, but even so, I can't help feel like I'm now a Beta tester for the Linker and it's effort to play nice with the Oppo. Not a happy camper right now. Sorry! Hope you don't have any issues.
Hi Steven,

I'm sorry you are having issues, really sorry: please understand that firmware 0.19a available on HDfury is same as firmware 0.19a posted here via filedropper.
The ReadMe and my post stated that it solves: Purple Tint when player was set in auto or 4:4:4 and audio loss. We also confirmed that 3D and 1080i issues were still remaining.
So sure, if you try to play 3D with it from Oppo, you will have issue.

Similarly if you try FW0.19 then you are back with purple tint and audio loss, so please stick with FW0.19a for Oppo

If you want to play 3D with Oppo, currently you have to flash the 0.19b that you can get from me via PM
We we did this quick 0.19b for 3D support on Oppo but it introduces some issues we had on FW0.17 and that were fixed on FW0.18 and 0.19 so it's really not a good firmware but just a temp fix to allow Oppo owner to play 3D.
If you want to try it, just PM me. Bdavidson tested it for 3D on Oppo. (But you will have to flash back to FW0.19a to get overall good operation from Oppo for everything else than 3D)

We are doing our best to bring a Firmware that will allow 0.19a + 3D for Oppo owners, it's not an easy task, so thank you if you can be patient for that.

One reason why on my new JVC, which has better HDR (I had a decent look at it and shot some comparisons even) I have only really been watching movies and not testing

Remembering what is important.

At some point you must just sit back and enjoy mate. Go with SDR WCG until the dust has truly settled. HDR is dead to me for the foreseeable future, even though it works out of the box on my JVC.

SDR WCG is the only picture I can truly just sit back and not think about if crap looks right.

I think I have been watching 99% HD Bluray anyway on the new unit.

OPPO203 shows 4000/0.005, 1100/0.005, 1000/0.005, 1000/0.000.


If you have an integral, connect your pc to the integral (because you have to use the pc gui, not the cell phone gui), select something that's call Info Frame or meta data info (can't remember ... but you'll recognize it when you see it). It will dump 20+ hex bytes of information when it makes a connection with UB900 playing a 4K HDR movie. Take the 20th hex byte and concatenate it with the 19th hex byte ... in that order. Convert that 4 digit hex value (2019 ... in that order) to decimal ... that will tell you the high end clip point of the mastering monitor. Just google "hex to decimal" and you'll find an on-line converter.


Good luck!

Edit: This is a mistake. At 400 nit input, you would only be 100 nit output, and would have 100 NITs left for rolloff


I purposely set the soft roll off to 200, because that would be 50% peak, allowing the other 50% for the roll off.

Edit: this is also in error, at 200 nit input, the output would only be 50 nit out, leaving 150 nit for roll off.

You could try 200-50-300,... if you want to follow the ST2084 curve shape longer.
1. Since I only have 45 max nits, should I instead be using 180-45-180, or 180-45-270?

2. Also regarding the hard clip point - should I cheat that down to like 2000 instead of 3000? If I do that, what do I give up and what do I get in exchange?

3. When using Ray's patterns to set the white clip point the general instructions say to clip at 4000. If we make a curve with a hard clip of 3000 or 2000 should we use that as the clipping point in the patterns instead of 4000?

Thanks!

The 1st 2 only matter as the ratio. So in Manni style it would be 400-100-, but the way I like to do it, ( the 1st number is peak max), you would use 45-11-.

As for the 3rd number, this is where you are going to deviate from the ST2084 shape. That can be anywhere below 400 NITs ( because at 400 NITs input, the ST2084 shape curve will hit 45 nit out).

You could try that. It will make the curve closer to the ST2084 shape, but will clip any content above 2000.

Yes. There is no point is being able to see content at 4K input if your signal can't get to 4K.
