Official JVC X30 / RS45 owner's thread! - Page 53

I wasn't trying to win, but if someone keeps correcting me in circles when I'm just following the definition, I mean come on

I see your point, however some of these folks(cine4home) have measured a ton of projectors. Not saying its gospel, but they certainly have enough experience to know what their doing it would seem.
It is also known that last year models didn't meet their spec's. JVC needed to do something to win its customers back. If those numbers are remotely close, I would say they're off to a great start.
And yes those JVCs destroy everything on the chart, including their parents and grandparents! lol

Was anyone successful getting their (new) JVC glasses working from 20 feet with a bounced-back signal?

Yah, you'd think, but some people measured the RS-45 as low as 20,000:1. It's not 20,000:1 though, those people had their meters floored too low making the error margin way too high. I am not an expert at these measurements, I just read an article in the forums about a trick from Tom Huffman and others about putting the meter closer to the lens to get the error margin above the floor.

I still see even seasoned reviewers hitting the floor of their meters, so if they do that then it's a pointless measurement. I think it just in the technique and some probably are doing something wrong, but like I said I'm certainly no expert in this.

Has anyone noticed how fluid movies look without engaging CMD? Several times over the last couple of nights. I thought the CMD was engaged. When I checked it wasn't. It is almost like the projector has a low level CMD built in to operate all of the time. Don't get me wrong, it looks great!
It's just the image is so clear and smooth sometimes it makes me think the smooth motion is engaged. I didn't notice this on the RS50.
I wonder if this is what they mean by upgraded optical engine?

Yah, the motion looks great and this projector is GRRRRREAT, as Tony the Tiger would say.

This is the first projector I've ever owned where I just really see so few faults. If I had to fault it in any way (and I hate to even say it, because it doesn't matter to me), I'd say it can't handle poorer sources as well as DLP for whatever reason. It looks so much better on blurays though. Still even with the issue of being slightly less perfect at poorer sources, I still prefer it over the DLP usually for the extra contrast sometimes even for that poorer source content, the DLP does look smoother in some cruddy source material though. Although I could probably calibrate another mode to do that better, but really too lazy right now.

Remember the thread about everyone saying how muted and flat the RS-50 was, it was just the lamp issue and showroom / calibration problem. It can happen in any showroom, that's why I stopped going to showrooms, too random. I went to look at a JVC RS-40 and the guy wouldn't even let me see the remote, I was like come on I can tell the contrast is messed up how am I going to buy this thing as-is. He said I might mess up the picture, I was thinking, wow more than it is already messed up, that'd be hard to do.

Realistically it just shows us how lucky people are (especially newbs) that call AVS and talk to Mark or Mike, because they will give good recommendations. You go into some of those HT places and the guy looks like a thug...

LMAO..sounds as though we visited the same theater show room!
It's sad when my meager setup blows a $250,000 one out of the water!
That's how much the demo room plus equipment cost where I viewed the RS50.

Mark and I are supposed to get together very soon for the W7000 demo. I'll see if he still has the 45 at the time, I'd like to see it side by side with my 55.

the lumen output of the new models is a bit brighter than the HW30, so I expect both to set the high power on fire.

has anyone calibrated their gray scale yet? several have reported a noticeable shift in gray scale in just 50 hours on the new lamp, red is the first to go.

I have the Chroma 5 pro warmed up and ready to calibrate.

Not yet, my old Eye-one probably is too drifty.
I have to order a new meter, I just haven't yet talked myself into spending the $500.

I still need to buy some more stuff, but I've just been buying too much stuff lately, and now I'm replacing the couch just so I don't use have to lens shift, lol...
My money tree is losing leaves in the fall.

Edited:
Also have found another bug in the calculator, for some reason it's adding extra inches to the lens shift values for certain projectors. It's weird and must be a bug that was created from Beta 021, so it doesn't do it for all projectors. I didn't even notice until just now. Must be the server is bad at math, can't be my fault
Generally it's just adding a few, so it probably won't be catastrophic but I need to fix it.

I have a practically new LT you can have for next to nothing. I used it about 4-5 times with color HFCR before I got the calibrated Chroma 5 Pro. It did a reasonable job on the RS50, I thought something was wrong with the meter when I saw red @ 82-83% @ 100 IRE, but the Chroma 5 validated the same exact thing.

let me know if you want it.

Sure how much you want for it?

Can you create an offset for it, or was it accurate across the board?

I'll send you a PM. I couldn't create an offset for it, but I have to say it was more accurate than I was expecting @ 30-100 when setting gray scale & comparing it to the Chroma 5 Pro.

The gray scale drifted a huge amount on both my 40 and 50 during the first 100 hours, so even with the LT meter, I think it goes a long way to keeping the flesh tones looking good. After the first few times, I could adjust the gray scale in under 15 minutes. Mainly focusing on getting 30 and 80 as close as possible.

I can tell right away when I forgot to disable CMD and pop in film based material.....there is no missing CMD being on/off when you pop in normal 24p film content IMO.

I was going to chime in on this, but you beat me to it. Judder is a term that's used for both effects - frame repetition (3:2 or similar irregular pulldown) judder and slow frame rate (24p) film judder. I really like what FI does sometimes, but so far I've never seen an implementation that doesn't create visible artifacts. I've had it in 5 different displays. I watch it for a while and then turn it off. I'd love to see what the Sony 30 can do with it, because of all the talk about how good it is.

Boy this is weird with people reporting being particularly happy with motion on the RS45, when blurred motion is my number one issue with my RS55 at this time! And I didn't have any problem with my RS20's motion.

If you have a specific scene in a movie you can think of so I can see where the motion is bad, I'll split screen test it for you against my DLP and see if I can tell if the JVC hiccups.

I am just not that sensitive to motion issues, but I can see these things easier if I split-screen against a DLP.

I had a similar experience with my RS45. It just seemed smoother than my RS40. I checked too see if CMD was on, but it wasn't. I only have a couple hours on it so far, with basic greyscale calibration. I think the contrast may be higher than my RS40 as well, and there seems to be less digital noise (the DLP-like dithering that folks have reported). Light output is a tad higher in low/normal lamp than the RS40 with similar hours, but a tad lower in high lamp and 3d (but my RS40 was great in this regard).

The contrast is definitely higher than the RS-40, it's gotta be at least 40,000:1 I'm thinking (heck JVC even rates it at 50k:1), and probably more like 50,000:1+...

The contrast is spectacular. I watched Harry Potter for 5 mins on the DLP after watching on the JVC, man that was bad, talk about needing the darker blacks on the DLP all of a sudden.

The JVC will spoil us with black levels and it'll get harder to ever own a non-JVC.
That's their dirty little secret, they give you a free sample and then get you hooked (ok wasn't free).

I'm with you guys on not using CMD for 24p movies. The only material I can see using it for would be animations and sports. I like my movies to look like film not live video.

Not sure what I've been seeing in regards to some movies looking as though the CMD were engaged at very low levels. Maybe it is just those movies that give the effect. It's not bad by any means, I like the way movies are displayed with this projector.

Thanks, now I don't feel like I'm losing my mind alone!

I've practically run out of movies to watch, name some good dark movies so I can go grab one. Already saw Thor but watched it on the DLP before I had the JVC, I suppose I could watch it again but it was just ok. Green Lantern has cool SPACE special effects, but the movie is pretty bad.

And which DLP were you comparing it to?

Just a Viewsonic Pro8200, but most DLP's look fairly similar in bright scenes.
The Viewsonic has poor black levels (good for the price but I mean in general), so don't let it worry you too much if your going for DLP

It's good at bright scenes though. I have had DLP's with better blacks before, just don't need one anymore since I have the JVC for the movies, so I have the LIGHT CANON Viewsonic for gaming and TV (1500 lumen best mode)...

Thanks, wow that was fast and was a bigger list than I was expecting )

Only seen about half those, so that should keep me going for a while.

I love U-571, really good movie, just seen it too many times though.

Yeah me too! Good to test projectors with though.
I have about a thousand of them here, so very easy to recommend a few.

The RS40 also had a contrast ratio of 50,000:1. Definitely higher? Have you compared them directly? How would you know? I love how the hyperbole just flows with new owners. The only thing at this point that seems pretty certain is the RS45 is brighter than the RS40. keep in mind, brighter isn't always better. In most installations (at short to mid-throw) all it will do is raise the black floor (something many of us don't desire).

Every online measurement has the RS45 brighter with higher contrast. Every professional reviewer has stated the same. I do not understand why it is hard to believe JVC can't make a great projector better in this regard?
Brighter allows you to use the aperture to its full potential, which also gives better contrast. Why would brighter be a bad thing for these projectors?

I'm not inclined to doubt owner reports of the RS45 looking like it has higher contrast.

JVC really does seem to have made a visible jump in performance. I've directly compared my new RS55 to my RS20, and the increase in image dynamics and contrast is quite obvious in favor of the RS55 (and frankly I was skeptical there would be a visible difference between the two, until I compared them).

I just looked at Kraine's review of both the X3 (RS40) and the X30 (RS45) and the maximum achieved contrast was 25,000 and 27,600 to 1 respectively. That does not constitute a significant contrast increase and could be totally attributed to margin of error. Regardless, the average human eye wouldn't be able to tell the difference.
