The top left corner of my projector kind of rolls off and not so much Square. Is this normal or is there a way to correct this?

Is the bottom left also sagging like the top? The bottom is less noticeable than the top as the sagged part will fall on the black border. To make alignment easier, it’s best to initially zoom to a slightly smaller size so that you can see all 4 edges of the image relative to the screen.
Assuming ithe sag is only the top left, that means the projector is aimed towards the right, rather than the centre of the screen. Turn it slightly to the left, and recentre the image using the horizontal lens shift.

The projector is slightly offset because it sits underneath a bulkhead and I wanted the pj to be centered with the ceiling not the screen or it would of looked funny with the bulkhead.

I thought with the lens shift that this wouldn't be an issue that I could judge shift the screen to center it

That is correct. My suggestion was to point more to the left from the current position, not to move it.

So is this projector 10 or 12 bit ? I read a couple of places that say it's 10-bit, but my info screen says 12 bit.

It'll show 12 bit in the info menu if you're source is set to output 12 bits. My understanding is 4K HDR is 10 bit and the extra 2 bit setting doesn't do anything for the picture quality.

I had my Panasonic UB900 set at 10 bit when Chadb calibrated my RS400, and he didn't change it when he checked my player settings.

On the other hand, I suspect setting to 12 bit does no harm.

Jvc x5000 and Sony X800

I'm trying to make the Sony player output Original resolution or Auto in the Video settings, but it can't get a handshake so defaults back to 480. I'm using HDMI port 1 on the JVC. The Sony player is connected directly to the JVC.
I have the same issue. The JVc can only accept 1080p out put from Sony. I thought the problem is the cable. But I tried to connect the Sony X800 to my Samsung series 9 TV using the same cable. It worked perfectly. I bought the cable on EBay for about $20. It says support for 18gb transfer.
But, if the issue is the cable, why it works with Samsung TV but won’t work with jVC projector? Can someone help?

Thanks :) Yeah, I can't use anything shorter, my projector in the back of the room in the ceiling and cable is running along the wall and floor. My room is quite small so there must be other installations and settings using this length?

I can't try a shorter cable less I demount the projector...possible of course :)
I have the same issue. My JVC x5000 projector can only accept 1080p signal from Sony X800 player. As soon as I output 4K from Sony, it goes blank. Before I bought the Sony, I used an Oppo 103 bluray player upscale the video to 4K. The JVC projector can display the 4K signal perfectly.
I can also display the 4K output from the Sony x800 to Samsung 4K tv.
Can someone suggest what is the likely cause the JVC Dla x5000 can accept 4K from Sony.

It's the cable. You should also replace all your cables while you are at it so you don't run into this again. You quoted someone who was talking to me and they did what I said and were happy with the results. I suggest you do the same. :)

I even made a fancy pants DIY guide to getting the most out of your projector with the least effort possible (click). It is specifically tailored to new RS400 owners or ones that are going to 4K for the first time, people that follow it are happy.

If you follow the steps in my guide EXACTLY, you will have success.

The only other possible thing it could be is the HDMI handshake sync time. The JVC takes almost 20 seconds to actually display an image after receiving a 4K signal (and usually again for the player menu, and again once you press play on a 4K movie). If you're in the player menu choosing 4K the player could be timing out the 'can you see this message' test it does. I don't know if the X800 works this way but if you try to change resolutions on anything it will confirm you can see it to avoid sticking you with a resolution you can't see. This confirmation message is usually shorter than the JVC handshake so you have to guess at what buttons to press to confirm the message because the JVC is still trying to handshake.

You're right, it does not make sense that the cable would work with another TV but not the projector. It could be the JVC wants a stronger signal than the Samsung, who knows...I'm not claiming it has to make sense, just that I know how to make it work. ;)

Could be that the Oppo sent 4k upscaled in less than 60hz and that the cable managed that. The Sony menu spits out 4k at 60Hz and that puts pressure on any cable. Not sure why the Samsung TV clears the signal though - did you use the same cable for the JVC and the Samsung? As Dreamliner says, it's most probably the cable.

I had the "Sony menu" issue on my initial "certified" 10 meter cable: The JVC would not render the X800 menu (60Hz) but would display the movie when running (24Hz). I read the extensive hdmi cable test posted here at Avsforum and settled on the RUIPRO fiber hdmi that was one of the two recommended ones for longer distances: https://www.amazon.com/dp/B01N6HM1RL?tag=vs-avsforum-convert-20

Sync problems with Apple TV 4K

I apologize if this kind of issue is discussed elsewhere in the thread; I did some searching but it's now almost 5000 posts long and I haven't yet read the whole thing, which I will probably do at some point.

I've had an RS400 for about a month. It replaced a 10-year-old RS1 that I thought was fine, but the improvement even on HD content (not UHD) in brightness, color, and image detail with the RS400 is startling. So I have very little buyer's remorse. Except...

The projector is not playing well with the Apple TV 4K which is our main viewing source (mainly for Plex and streaming services). At least half the time a format change in the output signal from the ATV causes the projector to completely lose its mind (so to speak). It displays flashing vertical lines, or horizontal streaks, or a flashing version of the previous image. When this happens the only solution is to power the projector off and on again. Since it takes 1m45s for the projector to power off and another 45s for it to power on again, it takes on the order of three minutes (while we sit in the dark) to get back to what we were watching.

The ATV can be configured to match (or not) the dynamic range and/or the frame rate of the source. I get the best image results when it’s configured to match both DR and FR so that’s what I’d prefer to use. In an effort to get past this problem I’ve played with those settings. It turns out that if either setting is “on” (i.e. match the source) the sync insanity can occur. When I turn both settings off there is no signal change at all and also no sync delay, but then 4K HDR content like “The Crown” on Netflix is so muddy and dark that it’s unwatchable.

Based on discussions above it seems that the darkness problem might be addressed by installing a custom gamma curve, and I'll be trying that soon. But if both "match frame rate" and "match range" are set to "on" (my preferred setting) then—when the sync problem doesn't occur—the projector behaves perfectly with the ATV, which outputs HDR or not according to the source. The "D" gamma curve looks fine in this configuration.

Has anyone else seen this kind of anomaly? It's a huge usability headache.

I should mention that I did not replace the 25-foot HDMI cable run from the A/V receiver to the projector. I was prepared to, but during installation the existing cable seemed to work fine, and when the projector actually displays an image it still seems fine. But...might an inadequate cable account entirely for this issue?

The A/V receiver is a Sony STR-DN1080.

Thanks for any help with this.

Leave it to Apple, the WORST Company in my lifetime...
Gamma D is garbage, JVC may be the 2nd worst...see above posts regarding curves...

I don't know anything about Apple TV but I strongly suggest you follow my JVC 4K QuickStart guide. It is rock solid. If you follow this guide and still have issues, it's the Apple TV. A bad cable will cause lots of weird and unpredictable issues like drop outs and such. I'd make certain you do that and...it's step 1. ;)

Did you notice you bought the exact same HDMI cable I recommended to you less than 40 minutes after you first posted trouble getting 4K to work with your X800? Interesting (but not surprising) that thread came to the same conclusion.

I've had my RS400 for 18 months and I have spent WAY too much time on this forum trying to get it to look the best it possibly can (because I've never been satisfied with its "HDR" performance). That is why I am so strongly pushing my JVC 4K QuickStart Guide. People are welcome to spend countless hours pouring over the forums but they will all ultimately reach the same conclusions I have. May as well just read the answer key. ;)

No offense - I read the AVS test and settled on the RUIPRO (one of only two cable that met all their standards) since the one you recommended (Monoprice) was not available for delivery in Sweden. As you know I am grateful for all the help I’ve gotten, and I’ve expressed that on several occasions.

I recommended two cables in that post, the Monoprice cable for 25 feet and under and the RUIPRO for long runs. The Monoprice cables are limited to 25 feet and are Certified Premium. The RUIPRO is the only cable I recommend over 25 feet.

I'm just glad you are rockin' 4K! Do you still have the X800? Are you running custom gamma curves?

There are A LOT of people surging on here with these projectors and 4K in general. Many are severely misinformed regarding HDMI and are getting screwed from companies that are lying about their compatibility and they end up buying 30+ foot long copper cables and wonder why it doesn't work. What makes it especially terrible is the usually only find out after running it through a wall.

It's not really their fault, a lot of the manufacturer websites are purposely very vague with 'compatibility'.

A good calibration will ensure whatever display you have will have the most accurate and 'correct' image possible. The RSx00 projectors (RS400/RS500/RS600) look amazing right out of the box for HD and 3D but they were released before any 4K content was available. They have a very broken and flawed HDR system which means that out of the box, most 4K HDR movies will look broken and nothing like the beautiful image you see now in HD. JVC has put out a recommended HDR settings guide that involves using Gamma D but even that is drastically flawed. With these default settings, you will never be happy with the way 4K HDR looks, this is not hyperbole.
....
Good luck!
Hi Dreamliner, congratulations for the excellent post, but what premode Gamma curves would you recommend for my X5000, installed in a living room, with sofas and light curtains?
Thanks, tanks

I need to test out the available curves more to see if I can lock down a solid single recommendation. I don't think the room makes a huge difference barring the extremes (all white, all black, sunlight or lights on). Of course, the darker the room, the better the image but I don't think that has much of a bearing the custom curve you choose. Try as many as you want until you find one you like. You've got 3 custom slots and you can over write them as often as you wish.

The reason I don't have a direct recommendation right now is I moved to SDR2020 and abandoned 'HDR' as I couldn't get a reliably good image on all discs. I talked about it at the very bottom of the JVC 4K QuickStart Guide.

I've walked a few people through the process and every one of them preferred SDR2020 but it requires an Oppo 203 or a Panasonic UB900 + HD Fury Integral or Vertex.
