Official JVC RS55/X70 owners thread. - Page 113

I'm afraid this question is illogical.

Thousands (tens of thousands?) of units have been sold. Have some had issues? Yes. Have some been perfect? Yes. Every projector ever produced has had some issues with some units. If you do not want to take any risks, buy from a dealer whom you trust and has a policy you agree with or buy one that has adjustable convergence that is flexible enough to adjust out any issues (like this year's RS56).

The idea of a projector existing that has never had any convergence issues at all doesn't make any sense. 100% perfection is not achievable in manufacturing.

Kal

There are some projectors like the Epson 5010 are known to have convergence issues.

I wasn't expecting 100% would be fine but thanks for the lecture anyway *******. You obviously didn't GET the intention of my guestion.

Thanks to the kind forum members who shared their experiences. Thank God most forum members are like you guys.

What he is trying to tell you is that there is no way to know if your unit will have good convergence or not. You're going to need to take it out of the box and see for yourself. So even if a projector model has a good track record for decent convergence this specific unit could look like garbage. This answer isn't something we can give you. As of late JVC has had a fairly good track record (higher than average I'd say) of units having good convergence.

He wasn't being harsh at all. Just telling you that its unlikely to expect something unseen.

This is a good point, you simply don't know what to expect on ANY of these models until you take it out of the box. My first RS55 was a poor sample, the convergence was off by quite a bit and the focus was uneven. There was no way to get consistent focus across the screen. By chance, the replacement was a 'golden sample' - meaning the convergence was as good as it gets for a 3 panel and the focus is perfect. (which is also why i'm not selling this one... )

So there's outright lemons, something in the middle and the golden samples. I think JVC could have sold more 65's and 66's if they guaranteed convergence and focus. I've seen examples of RS65's that didn't perform as well as my 55 due to offsets in the convergence and focus. I'd take that any day over some extra contrast since it's something you can actually see.

e-shift (1 and 2) imo, requires excellent focus in order to perform at it's best. the RS4810 I reviewed was a 'middle ground' performer, not terrible, not great. This really shows when the e-shift is turned on. If the focus is dead on, e-shift 1 looks excellent.

Yes, but I believe Tom Monahan was asking a more general question for the forum members, not to be told his inquiry makes no sense. Keep in mind, many, I included, don't have the same technical expertise or experience with pj's as some of the members. It's all in the tactical approach.

It's not that the question doesn't make sense, it's just a question no one can answer because no one knows anything about the unit he's getting. When and if he does get one he'll be the only one to tell. If I were him I'd ask the dealer to make sure his unit isn't bad or let him see for himself.

A good analogy would be if he was buying a car and was wondering if there was any issues with people getting lemons. Just because that model doesn't usually have too many lemons doesn't mean there aren't any out there. That's all we're saying. The only way to tell is to look.

True, but if you ask the question, and many respond with a negative, then he at that point may choose not to go any further with his investigation.

I think we're all adults here. We weren't being mean, just honest. The fact that they were negative responses is besides the point. He asked and we answered.

To make matters worse most people can not make an objective judgment about misconvergence. For example using a grid, how wide is one line, one, two, or three pixels. Without knowing this how can one make a good guestimate as to the degree of misconverhence. And many people don't understand the difference between misalignment on the screen caused by CA and not convergence.

Finally much of the misconvergence I see in screen shots is blue misconvergence. It really shows up against white but ones eyes are very insensitive to blue and blue is a tiny fraction of white anyway. But if they see it up close, its a bad bad projector when it isn't. I'd much rather have spot on red to green than blue to green cause in real life it doesn't make much of a difference. I know many will not acceot what I am saying but the AV Pros laugh when reading the many bitches sabout blue misconvergence and what a big deal msny consumers make of it.

An Epson os like a cheap Korean car. Don't expect the precision of a Porche or a BMW etc. Its still going to get you there.

What did you say about Korean care?? JUST kidding:D

I don't think many would argue about blue convergence, it disappears to the eye once you're a few feet away from the screen. I find CA more offensive when there is purple/green fringing.

focus uniformity is hard to contest though, especially on a nice sized screen. Who doesn't want their shiny new projector to resolve the pixels from edge to edge, top to bottom.

I think Mark is saying that obsessing over it is what's so funny. Obviously everyone wants perfection. Unless you're lucky enough (like you) to receive a "golden sample", which is very rare, you should expect a little CA and convergence issues. If it's particularly bad, exchange it. Most of the time, from a proper seating distance it isn't noticeable. This is why Mark's point makes sense. Too many nitpick, myself included, and have a hard time enjoying a picture because of some minor flaw. Most of whom wouldn't have noticed the issue had it not been for this forum showing them how to see those flaws or teach them to worry about such small NORMAL things.

I know there is no way of knowing if this particular sample is good or not. I was speaking in general to get an idea if the odds would be in my favor. You state that as of late JVC has had a fairly good track record (higher than average I'd say) of units having good convergence. THAT is the type of statement I was looking for when I asked the question. I realize that this isn't a psychic forum. I have had projectors for well over a decade and my first HT setup in 1988 so I'm not a moron on the subject.

I got burned when it comes to convergence on my current projector and don't want it to happen again.

Tom

I watched Finding Nemo in 3D on my 1000ES yesterday. I actually saw some ghosting which I have never noticed on other 3D titles on my 1000ES.

Where?

It was on a selection of three choices against a white back ground. Could see a T and a ghost T. no ghosting during the picture.

My God. Should I return it for service. What the F. I will never ever be able to enjoy 3D on it again.

Well Maybe I can live with it. Yea. I can live with it.

And the other day when switchig from 2D to 3D simply by loading at 3D disc the picture wouldn't come up. I actually had to shut my Lumagen to standby and then switch it to on. Two pushes on the Lumagen remote. WTF. Now I will never sleep again.

Remember Mad Magazine and Alfred E.Newman.

Who me worry?


Nothing wrong if you have to reboot something once in a great while.

Sometimes I think you hate this forum (or the people posting). You've always been quite fluent in sarcasm.

WTF?! Can't even get the quote correct? I hate this place!

Its native old age speak.

Actually I like helping people if I can and I have received lots of help from posters and have learned much.

But I do get tired of some who just never get it. Like that billyCrystal movie and the guy who can never get the concept of being able to record something without having to watch it at the same time.

my favorite story is about a guy I sold through AVS a new bulb for his JVC.

He called me up really angry. We sold him a bad bulb.

So i asked him a bunch of questions about what the bulb was doing wrong. Finally, when I determined the bulb was fine, I asked. OK What is wrong with it. He dsaid the bulb wouldn't let him reset the bulb hour counter. I told him it was operator error and he fought with me. i said, take the phone with you and i ewill read the reset instructions to you and you press the buttons on the remote. He really didn't want to do it saying it would be a waste of time but he finally agreed. If I remember correctly, the sequence must start with the projector being in standby. The first instruction. The phone went silent. He said, thatv was it. He would call meback if the sequence didn't work. I said don't worry, it was my pleasure to help and that I was guilty of worse. He left happy.

why did he think his bulb was bad? He read about all the problems people were then having with JVC bulbs and he figured him too.

Also you make a lot of buds here too. They visit you and you them. Get togethers at Cedia and CES. HT meets. Its all good.

I think Mark is the Larry David of the avsforum.

There is a bit of curmudgeon in all of us. North of 60 it seems to be more pronounced . . .

i actually got flattened by Larry David. We were both at the Teluride Film festival(not together, I don't know him). And my wife and I took the 24/7 free cable car to the new town up a mountain from the old town. We wandered around a bitand we were walking back to the cable car station to go back to our hotel in the old town. Larry was behind us and he decided to run and not miss the next cable car. He didn't see us and basically ran over me sending me flying and to the concrete ground. I wasn't hurt, he barely looked back to see what he hit. A classic hit and run. It definately was Larry. At least he could have yelled Pardon the Interruption.

You are so right. I was afraid to touch convergence until I was more familiar with the projector, but it's dialed in now. Blue was a couple clicks south and red was one click west of perfect. WHAT A DIFFERENCE! I think my 55 is a gold unit or is that member.

Great story.

I guess what you see is what you get with him. Now I know the bad may outweigh the good.
Edited by Tom Monahan - 2/19/13 at 4:06pm

Though he lives about 12 miles from me, I have never met him. Larry to be fair was going through a divorce at the time. Its just a funny story. No harm was done and his actions I don't think were deliberate.

At the same festival I actually spent about 15 minutes talking to Sean Penn though I had no idea till after the conversation who I was talking to. He was staying at the same hotel and in th morning he was standing in the hotel lobby waiting for his car. He was wearing a Boston Redsox jacket and cap. I am a Redsox fan and I went up to him and we discussed the Redsoxs. That's all we talked about for 15 minutes and then his pickup came, we shook hands, he said he enjoyed the conversation very much, and left. Then my wife and about 10 other ladies rushed up to me and asked what did he say. I really didn't know who he was. When that became apparent, they ladies looked at my wife and said why did she bring me to the festival?

I mentioned this in the flat panel new tech forum:

I've spent a bunch of time with the Sony 4K panel, watching it's loop of native 4K content off it's hard drive. Very impressive and I'm looking forward to good 4K sources.

That said, right after watching the Sony I came home and put on the Blu-Rays of Skyfall and Samsara (shot 70mm, mastered 8K etc) on my JVC RS55. I saw many shots that blew me away as much or more than what I saw on the Sony.
The absolute clarity in many of the Samsara shots on the RS55 (E-shift at 2, Darbee at about 25 percent looked even more precise and real-clear than much of what I saw on the Sony. My take away is actually has to do with how much better fully optimized sources can look at home, and so I'm excited to see just how great good 4K sources will look on 4K projectors optimized in our homes!

Hello,

got an annoying issue with m X70, which I hope you might be able to assist me with - I browsed through this thread and found some hints (warming up issues), but I am not sure, whether they really apply here. So thanks for bearing with me, beforehand!

In dark parts of the picture, I do get a huge shift to read - and I mean: huge. It looks like a dark red. Trying to describhe it is hard for me: it is not just some shift towards it, it looks blotchy and like a clearly bordered step (like a IRE-step on a test pattern). So for example in the face of a person in a nightly scene: between the hair and the cheekbone, you will see a big streak/area of dark red between the hair and the lighter parts of the cheekbone, with a clearly distinguishable border and no smooth transition between this darker and the lighter parts. Or, a shot inside a car: big parts of the interior show this darkish red instead of grey, cleary bordererd - everything below a certain IRE-level seems to be red.

I must add, that the x70 has been professionally calibrated (german reknown calibrator cine4home, I bought the "cine4home"-Edition of the X70, after my initial purchase of the X70 suffered from dead pixels and I exchanged it for that version). But no matter, whether I use one of their 2 calibrated settings (one with, one without the green filter in the light path), or the presets like THX or cinema-mode 1 & 2, this red-shift in dark areas is still there. It is also independent of the frame interpolation settings.

I tried to get rid of this color-shift by going into the cutsom gamma settings and tried to manually dial down red gamma for the IRE5-point. As far as I recall, it was set to 56, and I had to dial it down to 20 to get rid of the red. But then I ran into other problems in low light scenes: greyscale was not smooth anymore, I was loosing low end "resolution" of dark scenes completely.

Has anyone of you experienced this before? I must add, that the model, the I currently own, was supposed to be a new unit, but according to the measuring charts, was calibrated June 2012. And the housing seems to have been opened by someone: looking from the front, the left side part of the housing must have been detached, since it was fit back improperly and a little lug was sitting outside the housing instead inside it's counterpart in the other part of the housing and between the parts were stuck some longer orange plastic fibers (I wonder, why they opened it / did the dealer need to repair anything???).
I also have the warming up issue, some users described in this thread: for about 20 minutes, the entire picture has a big red-shift, that makes it quite unwatchable in all modes, that do NOT include the internal green filter (such as THX etc., Cinema modes with the green filter in the light path are way better during warmup).

So, what do you suggest, what I should do / look after?

UPDATE: I found the measuring charts from the calibrator, attaching them for your information, they used HDMI YpbPr (Video), Software: Milori Color Facts CF 7.5 + Calman + "other", Sensor: Gretag MacBeth i1 + "other"

I have a RS 56 that I purchased back in January. It has a little over 80 hours on the lamp and I plan to start calibrating it. I figured that it will take me 10-20 hours to figure out what I'm doing and get it right. This will be my first calibration. I plan on using Chromapure with a Display 3 Pro meter. Do I need to calibrate it for each source? I have a oppo 93 and a directv DVR that goes through my Anthem D2 sound processor. I have another cable for 3D from my Oppo 93 directly to the 56.

Can Anyone tell me if this projector can do the remote app of a i phone? cheers

Yes, it is IP controllable. I use Roomie Remote.
