Official JVC RS-50 Owner's Thread - Page 7

Sorry Jon, I was refering to the other RS50 that Jeff calibrated, but I'd overlooked yours. While 70 hours is still a little 'green' for a calibration, I'd have thought it should be settling down by now. Maybe there is an issue that JVC need to address, hopefully a firmware issue rather than hardware which is a bit of a pain if you've already paid for a calibration...

Here are some screenshots. The first 3 show THX mode out of the box with aperture at 0. Aperture changes DO affect the result.

The final screenshot shows greyscale after calibration. Notice that 100 IRE is a bit out but that can be tweaked later with gamma.

I wonder how it will compare to the RS 40 and to Sony 90ES.

Jon - looks great. Are you going to touch up 95%? The jump to a dE of 4 from nearly 0 is likely visible on the results.

Can you post the measured gamut and luminance of your color calibration? Something sounds very wrong if the controls did not have sufficient range to move all the targets to their correct Rec 709 positions. That was basically the issue (among linearity problems) with the RS20 CMS before the firmware fix.

Where are people getting their Oppo 93 players? I thought they have not been released yet.

I found my HD350 changed markedly from an initial calibration I did at around 30-40 hours compared to 150 hours, but I guess when Jeff comes back it'll only be a relatively quick tweak to get it back on track. It was more any possible issues with updated firmware or early failures that would put me off paying for a calibration very early on. I guess judging by Jeff's reputation on here that he'll 'look after you' anyway.

I recently calibrated a new TV as I rented an i1Pro for a week to do my HD350 plus VideoEQ Pro and the TV failed a few weeks later, so the replacement will need calibration. At least I'm just paying for the rental of the sensor I suppose. One day I hope to own a projector with a more stable light source, so I'll treat it to a professional calibration once it's got a few hours on it.

It's a limited pre-release to a few select owners...

I will fix the linearity. This was a rough and ready first pass.

I aborted the colour calibration because I just wasn't getting anywhere. I could see luminance adjustments quite easily but I didn't need to change them much as you can see from my original starting point. But I just couldn't get anywhere with hue and saturation at all. So I'm afraid nothing to post. What do you think of the "out of the box" numbers? The greyscale isn't wonderful but I think fairly typical. I have never seen such good luminance figures out of the box though but shame about the red saturation and yellow hue. However I want to test it again as I was using the Duo's built-in test patterns. And I want to check again with the AVS patterns although they should be the same.

adidadi..

How do you like your AV7005?? Interested in your comments. Have you seen the UD5005 bluray that matches it??

Congrats on your RS50..

I don't really pay much attention to any of the out of the box numbers. To me its irrelevant because no matter how bad or good they are I'm going to dial them in where I want them. For those who don't plan to calibrate, or who won't calibrate until x hours then OOTB results are more important.

For me all that really matters is that a display is capable of being dialed in. We know that's the case with the grayscale. We know that's the case with the RS20 CMS. And we've heard mixed things about the RS50 - both from the same person (umr stating one was shaky, the other was great) and now we have a report from you that the hue and saturation controls do not seem to be working. I assume that's the case with all colors, or did you try one color in particular and then give up (and if so, trythe others). Very odd. Let us know what you find when you are able to test more.

Maybe it's a good time to open an RS50/60 CMS Calibration thread.

Right
Then post the link so I'll subscribe the thread
Thanks

Well I don't have my 50 just yet but I should have it tomorrow after I drive to Rochester to pick it up (fortunately I was higher on the preorder list than I figured ). But I won't be attempting to calibrate it for a bit.

Well, Congratulation

If all goes right, I'll get my RS60 next 22 or 23 Dec...
Just bought some 3D Titles to shot and try ...

Should get my x7 just after Christmas. Just returned the Sony due to poor 3d performance. I'll post my impressions in the vs. Thread. The Sony was a fantastic 2d machine, but the 3d was dim and had tons of ghosting. So far the Acer is the projector to beat for 3d. Lol.

John - what meter are you using? I found that my old I1 D2 was bad about measuring changes but my I1 pro is much better.

Thanks!
I'll keep my fingers crossed for you and everyone else waiting. I know I got on the list early but I wasn't sure if I'd make the first cut.

It'll be interesting to read your take on JVC motion....Hopefully the JVC scratches your itch!

I bought a high quality 15ft. M/F mini-din cable for testing what a direct line of sight to the screen (vs. a bounce), would do and I'll report back what I find (soon).

I think I came across the same web site...could there really be that much of a timing difference buncing off a screen 15 feet away ( so a 30 foot roundtrip) vs. a direct line of transmission of 15 feet? Curious if this has any impact on what little crosstalk I see...

The speed of light is (roughly) 300,000,000 meters/Second - a 30' round trip will take just about 30 nanoseconds. There may be less IR interference and perhaps the glasses won't lose sync as easily.

Hmm...I switched from the DVDO test screens to the AVC disc and got slightly different results. The gamma tracks somewhere between 2.1 and 2.2. The greyscale has a similar dE although green and blue track together rather than crossover. And for the colour gamut, it actually showed slightly better with all colours being under dE of 10. However, the basic trends were the same, with the largest errors being Red being out on saturation, and yellow on hue.

No change in behaviour of the CMS though

I am using a Calman enhanced Spyder 3.

First - the speed of light is many orders of magnitude faster than needed to keep the correct timing. Second - running the signal thru 15ft. of copper wire also incurs a similar, but still inconsequential, delay. A 30 ft. total round trip of the IR signal requires about 0.03 microseconds which is far too short to result in any sort of timing issues compared to the approx. 8 millisecond (for 120 Hz 3D video refresh rate) cycle time for the 3D glasses.

...and 30 nanoseconds (.03 microseconds) is well within clock drift tolerances of most CE devices. A typical laptop does a lot worse.

From display work, a human's perception ability for change is usually in the 10s of milliseconds.

Well I pulled the trigger and ordered an X7. Got a 110" Stewart firehawk G3 screen, i was informed this is not the best screen for 3D, i was wondering if some more informed users can confirm this. Now to find a mount, emitter, and some glasses. From what i have read this should be a huge improvement for 2D content over my current RS1 regardless of the screen.

Personally I'd go by the patterns coming out of the blu-ray player. Calibrate 100% to D65 using each sources on two different presets. Then flip between them. Which looks the most like a cloudy sky on a totally overcast day? That's the one closest to D65.

The CMS not working for your is quite confusing. I assume its not operator error, but just to double check, have you used the JVC CMS before like with the RS20?

Glad I didn't lay out money for the cable!

The cable costs less than a beer.

Well theater fans, today I got my RS50 hooked up and the glasses and emitter finally came. I can say without a doubt that I almost fell off my chair with the quality of this projector. I had an Epson 1080 (from 2006, non-UB) and I just can't believe the difference in picture quality.

The 3D on the RS-50 is ABSOLUTELY STUNNING. I never thought JVC could pull off, to this extent, such amazing looking 3D with plenty of light and SO much clarity. My Elite 150" 1.1 gain screen is working beautifully. Those of you who are waiting on this model are going to literally be blown away. This is just on the THX setting out of the box!

I tested 14 3D blu-rays out of my 24 and did not see ghosting at any time, the picture was absolutely perfect on all of the discs and I have to say that I have not seen 3D look this good in most theaters (Imax was similar but no other).

This is the best Chaunukah present I have ever bought for myself. I am going to have to watch my entire Blu-ray collection over again and any 3D film that comes out is going to be on my shelf.

HATS OFF TO JVC!!!!!!!! UNBELIEVEABLE!

My only problem is that while I have been a home theater junkie since I was 17 (I am now 48), I really know nothing about many of the settings and CMS, ect. I just used the THX picture. So I hope in the future on this thread that some of you who are familiar with all of this tech will post your settings so some of us who aren't so inclined can try them out. I am in a small town so there is no one here to calibrate anything and I have tried calibration discs before but for some reason I just don't get it...so I hope some of you will post your settings.
