You might ask your Calibrator how he will be dealing with HDR. The "Custom Curve" method is a relatively recent discovery, and it is possible he's not aware of it. This isn't the only way to get a good result (ChadB, a well-known Calibrator, apparently uses a different method, but he is universally acknowledged as one of the experts on this), but it definitely offers a clear path to a good result.



Good luck!



Don
Thanks for the mention. Actually I do use custom HDR curves. At first I made them exclusively with the JVC software and now I do them with either that or Arve's tool.

Very interesting - good to know!

Wait, I just read your first post about your HDR issues with this projector. You realize the cable will do nothing to fix that right?

Your HDR issues are a combination of bad settings (based on what you posted) and this specific projectors inability to properly display true HDR. You can get fairly good results by uploading a custom gamma curve into the projector, but don't expect LCD or OLED results.

I have the same projector and OPPO 203. You need to upload a custom gamma curve and get your settings straight or you will be chasing your tail.

Based on your settings posted, your installer did not properly upload a curve.
Thanks for your reply as we are diving into this fully this week. I'm trying to absorb as much knowledge from you all so I can be somewhat educated when talking to my calibrator & home theater installers when they come back out this week to hopefully get my 4K HDR stuff looking great. Everything has been perfect until I got 4K HDR devices (Oppo 203, PS4 Pro and Roku Ultra). 1080P and 4K (non HDR) do look awesome at the moment but I bought the Oppo 203 and the Roku Ultra for the sole purpose of being able to at least enjoy HDR (realizing it won't be on par with a native 4K projector or other displays)

Potential Cable Issue: With current Audioquest Pearl 12M cable, when I put everything to auto or anything over 10 bit, or when Deep Color is enabled with HDR, I get sparkles, "snowflake" effect on dark scenes. Word is that full spec HDR can not be passed optimally over 25 ft? I have 40 ft of cable run through ceiling to my AV rack. Could this be the result of cable struggling or not being able to handle the full bandwidth required for full spec 4K HDR? Monoprice certified premium HDMI cable arrives today along with Celerity Fiber Optic HDMI Cable arriving Wed that installers will test. I would think I shouldn't be getting any snowflake effect or sparkles if the cable is good.

My JVC DLA X550R doesn't have the BT2020 color profile: My installers will be addressing that this week. Hopefully from there, calibrator will be able to dial things in optimally for 4K HDR as the calibration he did for 4K and 1080P looks absolutely sensational. Does the BT2020 profile "unlock or open" a new profile of colors for 4K HDR? Could that be the missing link? So step one download and install the BT2020 profile via LAN cable via PC? Firmware updates are done via RS232 cable and PC?

My JVC does have the u83.2 software. Is that the latest and no further update available to address any HDR/HDMI issues?

Thanks much everyone for any insight and assistance!
I would be linking your calibrator to these forums. Specifically the JVC software calibration forum.

I would imagine that the info on these forums will surpass any methodology that he will use to calibrate the projector. The reason is the calibration info on the forum is crowd sourced from numerous owners, and technical people. Numerous hours have been spent "figuring out" these projectors.

If your installer just shows up blindly again, it could take numerous hours for him to then read the forum and figure out what needs to be done. That way he doesn't spin his wheels.

Considering how he calibrated it the first time, he needs to be armed with this information first.

There are known issues with Roku Premier/Ultra HDR and the projector locking up. Doesn't seem to happen with other sources.

I have been having this issue with my rs400.. On scenes where the background is dark like the opening credits, the area around the bright images will glow..Is there a setting I can adjust or is it a defective unit?
It was bought as a B stock from avs and it should still be under warranty.. The issue has been there since day one but I never paid attention to it..

I have notice a light "streaking" up and down when I first set-up my PJ but I haven't notice it much lately...I have had the PJ professionally calibrated by Chad B so that might have something to do with it. Of course, I might be use to it by now...:eek:

What size and aspect screen?
What screen fabric are you using?
What throw are you using?
Normal or high lamp?
What manual iris setting?

I am trying to determine, just how bright you are running your image. Also what does it look like from your viewing distance? Streaking is a common problem and most all of them have this to some degree, but the amount does vary. Problem appears worse if you run the image real bright.

Hello, everyone.

I am about to pull the trigger on the RS400, but I would like to confirm that the projector can be mounted in the same place as my current projector, using the vertical/horizontal shift and zoom.

My HW50ES Owners Manual had a chart that could be used to calculate the mounting distances, but I don't see anything like that in the RS400 manual.

Is it on their website somewhere?

Thanks!

***EDIT***

Nevermind, looks like I just needed to do a quick google search. I found http://pro.jvc.com/pro/lens_calc/HTML/jvc_REF.html, which gives me what I needed.

Hello all. I currently have a Chief RPAU mount. Can I use that to mount the RS400?

Yes, same as me, you need adapter plate SLB281

Thank you for your response.


If I ended up using the SLB281 adapter plate, will I need to put any more holes in my ceiling? Are there any directions on how to use that with the RPAU mount to make it work with the RS400?

See my answers below.

What size and aspect screen?
What screen fabric are you using? 155" 16:9
What throw are you using? About 14.5 feet
Normal or high lamp? Normal (Economic)
What manual iris setting? Is that the lens aperture setting? It is set to Auto2.

I would not consider the image to be extremely bright. I actually consider it to be just bright enough to fill the screen in low lamp mode. I can see the issue clearly from the viewing position but luckily it only happens in scenes like opening credits.

You should not use the universal plate. You need to get the custom plate. I would call the dealer that you bought the projector from. I am sure that they could walk you through all of this. :)

Maybe I'm not understanding you here.
I've got this RPA mount



It hangs off a pipe, that is flange screwed to my ceiling backer joists


So that RPA adapter plate is specifically for the RS400 and RPA 6 thumb screw attach.

Have you looked on their website?
You can find exactly what you need, and AVS store sells it.

Thank you gentlemen for the info and feedback from my earlier post(s). Installers came and replaced the 40ft Audioquest cable with the 40ft Celerity fiber optic HDMI cable and that immediately resolved the snow flake/sparkle effect I was getting with the Audioquest Pearl cable. My Roku Ultra was finally and immediately able to confirm the 4K UHD setting for the JVC. The Celerity fiber optic cable is a winner thus far and resolved some issues I was having.

I was also able to download and install the BT2020 color profile for the JVC. Things look so much better with the vivid colors, contrast and pop. I still need some fine tuning with a re-calibration but at least I'm in the ball park.

Thanks again!

How do you install the color profile?

I've been loving my RS400, but I have one issue.


The center of my image is about 1" higher than the corners. I thought at first it might be my screen, but I have measured that and it is completely straight.

I am including a crude exaggerated sketch for visual aid. :)

Any tips or things to check?

Sorry, meant to respond to this yesterday. I assume you are not using an A-lens? Also what size and aspect ratio screen are you using?

No A-lens.

Screen is 138" 2.35 ratio, throw is about 15.5 feet. I notice this when zoomed on widescreen scope images. I haven't checked whether or not I really see a difference on regular 16:9 content. I can check that tonight.
