Offical JVC DLA-RS4810 Owners Thread - Page 31

Yes and projector. Maybe it won't be perfect but maybe it will help some get closer to a more accurate picture than just the standard settings (if they have a similar setup).

If it helps those who just tinker with the settings to get a good looking picture (like I was before I got mine calibrated) maybe this will give them a good starting point??? Not a bad idea, doesn't hurt to save it in a custom slot and see how it looks. Not everyone has measuring equipment or had theirs calibrated.

I believe most understand the variables in a setup and how that affects the overall image.

Sorry. Didn't mean to come across that negative, but I can see how I did.

I tried this and I think it looks pretty good. I was using "normal" (2.2) gamma with the dark level bumped up 4, and I also was experimenting with the "film tone" up a click or 2. I think this new gamma curve looks better. I actually think it makes the brighter scenes pop a bit more than what I was using. The 4 clicks of dark level adjustment (and messing with film tone) was probably more aggressive than I realized, causing the brighter images to "flatten out" a bit. But I'm just guessing.

I'm sticking with your setting now. I'd still like to be able to pull out more shadow detail, but I haven't talked myself into getting a lumagen yet (though I'm working on me).

Just curious though, I know you said this measures low, but how low is it measuring? And is it a flat gamma or is it doing an "S" curve?

I tried this. The image is pleasing. Watched the opening of Captain America; it drew out a little more of the opening castle scene and the black leather coat worn by Schmidt.

Page 6 in the calibration reports in post 42 of the RS66 thread shows what JVC's "Normal" gamma profile looks like:

If my '66 is representative, there aren't any ideal gamma factory presets. You have to go custom to get it right...

I am strongly considering this PJ for my yet to be built HT. They broke ground today on the house so in 4 months or so I will be starting to set it up.

Do any of you notice any motion issues with sports for action TV or movie sequences?

I am not a big fan of 3D so what if any I watch will be a real novelty and not important so 2D is vitally important to me. That is why I believe I will be better off with the RS4810 than the Sony 50ES. I also like the idea of CIH simplicity with the lens memories. I would love to be able to go up the JVC ladder to a RS66 but that is not going to happen so I believe the RS4810 is a great compromise for me.

If you are sensitive to motion issues, you will be with blu ray movies anyways. But with sports, it watchable for me with the clear motion on low. Not better than DLPs, but for movies its much better in this price range.

I just noticed a weird issue with the e-shift on my RS4810.

What I am seeing is a type of noise or dithering in the image. It is most visible along the borders of high contrast areas. The edges look "alive" as though they are crawling with noise.

This is with e-shift off


And thisis on


These aren't great pictures, but I think it captures the "noisey" edges I'm seeing. And in real time this noise along the edges is shimmering or crawling, not static.

The pictures are with e-shift in FILM mode, dynamic contrast and smoothing at 0 and enhance at 50. The image is solid with e-shift off, and with it on it gets this shimmering noise. On certain patterns it is easily visible from seating distance.

I've been playing with e-shift on and off for a while, and I don't think I was seeing this until recently. What I've also seen is that with e-shift on, if I turn down enhance all the way to 0 this effect mostly disappears.

Is this normal for e-shift and MPC? I know there are differing opinions about the bennefits of e-shift and some think that using the MPC sliders can make the image look to "processed" for their tastes. But I haven't read anything in the forum about e-shift/MPC adding obvious crawling/shimmering like what I'm seeing here. In seeing this type of "crawling noise" along high contrast edges from normal seating distance, I would think that it would have been pointed out here already if it was normal.

Thoughts?

I'm curious as well, I'll try it on my RS55 w/ E-shift 1.

I noticed a difference when comparing e-shift 1 (top) and e-shift 2 (bottom), I wonder if this has anything to do with what you're seeing.

This picture is from the Spears and Munsil blu ray. It is from from chroma alignment pattern. Once I noticed this, I just looked for a pattern with bright colored lines and this one seems to show it off really easily. Visible from seating distance of about 1.4 screen widths

Yes, I remembered these pictures of yours where the pixel structure looks a little weird. But what I am seeing is literally moving/crawling/shimmering along the edges, and I didn't remember anyone saying they were seeing such a thing.

I have some iPhone video of it (quality os only so-so), but I'm not sure how to go about posting that.

What kind of content are you seeing it with?

you can post the video on youtube and post a link.

my calibrator showed me on a test pattern and he was using a test pattern generator. Mine wasn't crawling but had a distinct yellow shadow/noise to the right of the solid line. It was very noticeable. I thought this was normal???????

e-shift off


e-shift on


In real time, the rough-looking edges you can see here seem to be crawling. It kind of looks like as if this were a special effect and these lines are "electrified" or something.

This is using FILM with enhance only at 50 (dynamic contrast and smoothing at 0). And what I am seeing is easly visable at 1.4 screen widths (my seating distance). Keep in mind, these pictures are somewhat blown out and hiding it somewhat. In reality it is much more obvious. Plus the rough edges are basically moving.

I put in some real movies and it is also visable in normal material, although in that case you have to be lookng for it and it's not as obvious. But I paused on a cityscape scene in The Avengers and I could make out these "crawling edges" on some of the buildings.

If this is how eshift 2 and MPC is supposed to look, then I'd never use it and I can't imagine anyone here being comforatable using it if they were seeing what I was seeing. It would only be worse and more obvious at a closer seating distance where eshift is supposed to add the most benefit. But ultimately I need to find out if my unit has a problem that needs to be addressed or not.

So, from seating distance (not up next to the screen) put in Spears and Munsil and go to the chroma separation pattern. Using eshift in FILM (or any other) and with enhance at the mid-point, do all of colored lines and edges look shimmering/crawling/electrified. What I'm seeing should be very easy to see from seating distsance. Even if you weren't told what to look for you'd see it right away. It would be very obvious to anyone. So if you'r eseeing a stable image without crawling edges, then there's something up with my unit.

Appreciate any feedback you guys can offer.

Actually I think I am seeing the same thing. And I did not see this on the RS55 to my recollection. I've maintained for some time now that I prefer eshift1, To me eshift2 does not look natural and I've resorted to turing it off for the most part. A definite let down for me.

If I wanted to buy a used pj with e-shift 1, would I also get the bad bulb design? Or was there an e-shift 1 model with the new optical setup and new bulb design (and I'm not just talking about the "flapper" bulb to try to fix the problem).

I saw a similar effect on an X55 I saw. They put on an Adele concert BluRay and there are lots of close ups showing her face and the microphone. I kept seeing this effect around the edge of the microphone body (like a kind of moving ringing effect) and just figured that they must have set the MPC settings too high in an attempt at a 'wow' effect (and/or maybe sharpness was ramped up). In any case it wasn't an effect I cared for having previously seen the same disc at home on my X35, but I'd presumed it could be toned down as I don't recall seeing the effect the first time I saw an X55.

After looking at these photos of e-shift 2, I think I'll change my search to a used RS55. If anyone has a RS55 with excellent convergence and focus, PLEASE pm me.

Kelvin,

Wow. Yeah, a moving ringing is a good way to describe what I'm seeing. I'd have bet good money that this was some sort of defect because I really can't process how it could go unnoticed by reviewers and the members here doing shoot outs and comparisons. I still have to wonder if what I'm seeing is somehow an exacerbated effect.

I'll try posting video later. I'm trying to do it now from my iPhone and it keeps failing when I try to post it to YouTube.

I don't know if it's something that gets exaggerated with certain content since we watched various other clips of westerns and action films but I particularly noticed on the Adele disc since I'd watched it only the day before at home so it was familiar to me. However, there were half a dozen other guys there and they seemed to be in awe of this projector so I didn't feel I wanted to stick my head above the parapet so to speak (especially as it was a whole day event and we saw and heard some other amazing kit that day, it seemed churlish if not rude to be negative).

@seanbryan -- I just checked and my 4810 doesn't have the shimmering effect either. It looks just like SOWK's image and edges are rock-solid with no crawling.

I'd check your BD player (and any other equipment in the signal path) before you conclude the projector's at fault.

Wow. From a sample size of one (maybe two), and from screen shots on top of that, you've decided that last year's model is a smarter buy? I think I'd go look at an RS48 in person before I came to that conclusion.

Mode and MPC settings?

I'll definitely do more trouble shooting, but in what way would the BD player cause this if the image is completely fine when eshift is off and then gets messy ONLY when the eshift is on?

For me Film 20,0,0 and Darbee 35

SOWK,

Just to clarify, your seeing it just as clean as your pictures above even with enhance at 50, correct?
