Correct. One of my friends who owns a JVC X35 was really looking forward to this and happy when he tested the X5500 I had here, to notice that CMD FI had become available for 3D program content.

Based on the rs640 sample on display at Cedia, bright corners are alive and well unfortunately.

I think your odds of seeing it are actually higher as you move up the model line due the fact that JVC needs to hit the high contrast specs for those models even when they can't achieve that across the entire panel. End result, you get a very dark center (to meet the paper specs) but closer to their bottom tier projector (rs4xx) contrast at the edges.

Of course luck plays a role and spending extra on "hand picked" parts doesn't appear to improve your odds. @Cine4Home usually does a series evaluation where they report % of units affected by a specific defect but I don't recall what they found for bright corners in the past.

Not for me either on the RS600. 3D was basically unusable due to the migraine inducing flicker. Maybe on some darker content but most 3D tends to be brighter CGI stuff where flicker was very apparent.

have higher than average native contrast and bright corners.

My RS600 had bright corners. Well, I wouldn't use the word bright, not sure who came up with that . It's a subtle non uniformity at the corners really but certainly noticeable by the naked eye. I could not see
anything visually on a movie that would distract, I'm sure a uniformity test would have easily picked it up though .

Thanks for the 640 info. Doesn't sound like JVC has a better grip on bright corners if even their sample there had them. This is why I can't get excited about possibly wasting extra money on the 6xx models as they guarantee you nothing, and they have now lost their best feature which was the 5 year warranty.

Time to play the projector lottery I suppose and hope whatever 540 hits my doorstep doesn't have bright corners like my 520.

Agree about your 3d comments. I can watch hours of 3d on my single chip DLP with no issues, but due to the JVC flicker and the fact that most 3d films do contain mostly bright flicker inducing 3d, one 3d film a night was my limit with the 520. I'm still surprised more people on this forum are not bothered by this.

I've had 7 RS600's here, 5 RS500's and a few RS400's. There was a range among those copies. 2 were unacceptable (1st production run), mid-range, and 2 that were golden samples with excellent uniformity. One of the reasons i'm keeping this particular RS600. Overall remarkable copy with lens focus + dead on convergence

I've also seen 25K VW1100's with large convergence issues and xxx series Sony models with less than perfect lenses. A 1 in 5 chance of a GS based on Ekki's #'s over 100's of samples on that series.

maybe he will extend his cherry picked Cine4home edition models to the US...

Anyone know if any universal mounts work with the RS520 or RS540? I found the mount that lots of people buy earlier in this thread, but the one I currently use is low profile and works pretty well.

Here it is, and the arms extend to varying lengths to accommodate different hole patterns. ABTUS AV817

Unfortunately, I couldn't find anything on the RS540's mounting setup either.

I'd much appreciate any info!

Depends on the person. Maybe it is like the RBE. I can only watch DLP for a very short time before it drives me absolutely crazy.

I was this way with RBE on my first rear projection DLP set back in 2005 and ended up returning it. I have fortunately NEVER seen one in 3d with the glasses on with the Benq 7000.

Interesting. Maybe RBE is somehow "masked" by the 3D on a DLP. I've never watched 3D on a DLP. It will be interesting to see if flicker bothers me on the 640.

Yes, this is one of the reasons I have not bought into the "it's due to the wonderful new higher contrast" argument for the bright corners.

In fact, as I'd mentioned before when this discussion was happening on the RS600 model, I had two RS600s with bright corners that replaced an RS57.
The RS57 had rated 120,000:1 CR vs the RS600 having 150,000:1 - so not much of a contrast bump. But the RS57 was virtually perfect uniformity while having extremely deep black levels, vs both RS600s which had very visible bright corners. I was able to directly compare the RS57 with the RS600s. And it's not like the bright corners were similar in darkness to the RS57's black floor, but only looked lighter because the center of the RS600 back floor was lower. The bright corners were just obviously elevated in brightness vs the RS57's black floor.

More important, the bright corner issue did not ameliorate much, if at all, when lowering the contrast on the RS600. In other words, I could have the RS57 on it's highest contrast setting, iris closed down - or any setting - and it was essentially uniform. Whereas the RS600's bright corners remained no matter what brightness or contrast setting - iris full open (making the contrast less than the RS57) or closed, it didn't matter. There was always the lack of uniformity.

I can see RBE on the W7000 DLP that Toe has in 3D, it's one of the reasons I sold it for my current Sharp 3D DLP which is much better for me from that perspective.

for 3D on the JVC you should allow for a 'warm up' time of about 15-20 mins to let the panels settle in for maximum x-talk performance.

While the flicker has made zero improvements, the ghosting has made MAJOR strides on the newer JVCs which I was impressed with as well. Hopefully they can do the same for flicker at some point.

Which Sharp 3D DLP do you own?

Didn't know that about letting the panels warm up. Thanks.

That's interesting to read. The flicker always bothers me on the JVC in 3D, but I've always found that after 15-20mins of viewing, I don't notice it nearly as much. I had always assume my eyes/brain just took that long to adjust and filter out the flicker. Is it possible that warm up reduces the flicker also?

No. Likely to be no DV support on any projector, ever.

They won't even sit around a table with Lumagen to even discuss it going in a VP either.

Frankly Dolby can stick DV where the sun doesn't shine, bring on HDR10+ I say!

If warm up time does reduce flicker, it wasn't anywhere near enough. Ghosting is a different story and the warm up helps significantly which gets the ghosting to a very minimal level.

I would expect warm up to make flicker worse since the fluid has a faster response time as it heats up.

Don't have bright corners on my 520. But convergence is a bit off at the edge.

So it's just lottery.

So, the question is, if you get one that has real bright corners is that something JVC would take back and replace?

Didn't know that about letting the panels warm up. Thanks.
I have a pair of Sharp XV-Z30000 3D DLP's, these are long out of production but still one of the best 3D DLP's out there.

Spoiler!

after the 15-20 min warmup the x-talk is noticeably better vs. cold boot and I do see some reduction of flicker.

I watch all my 3D movies on both the JVC and the DLP. both have their own advantages. The JVC kills in contrast on movies with lower APL scenes. They get flat real quick on the DLP's with only 2K:1 native.

Here it is, and the arms extend to varying lengths to accommodate different hole patterns. ABTUS AV817

Unfortunately, I couldn't find anything on the RS540's mounting setup either.

I'd much appreciate any info!
JVC had a new mount at CEDIA for their projectors.

Okay... big question... Will the new RS640 allow me to turn off e-shift if the projector is receiving a 4k signal? This is going to be a problem for me if it will not allow this.

I have run into an issue where my new Panasonic UHD player looks like hell (super soft) when outputting 1080p signal. I would prefer to output 4k and not use e-shift (the buzzing vibration noise is way too loud for me and the projector is about 4 ft behind and 4 ft above my head).

7.4.6 system: Processors:Marantz 8805 || Xilica XP4080 Amps: Parasound A31 and ATI AT528NC & AT526NC n-core ||Speakers: Procella P8 LCR, Procella P5 for surround & ceiling
Subs: JTR Captivator subs: One S2, Two RS2, One S1, 2 Seaton Submersive (FOR SALE)
Screen: 2.40:1 Seymour XD Acoustically Transparent, 128" diagonal / 118" wide || Projector: JVC X570/RS420

No. When you send 4K, it turns eshift on. Why is the Panny looking soft with 1080p ? You might check the settings on it. That doesn't sound right.
