Offical JVC DLA-RS4810 Owners Thread - Page 2

Here was Gary's response as far as the 2 questions I asked a few posts up which I linked here as well................

1. Any chance for a "game mode" this year to improve lag? Maybe it is to late even at this point, but then again maybe, just maybe this is something they might finally add after all the years of people requesting/asking for it? Is there some sort of technical limitation/reason for them not making this very popular request a reality? Any somewhat serious gamer considers 80ms of lag too high and many people who game to some degree end up not buying JVC projectors and end up going with a competitor for this very reason. Any chance for a game mode this year?

There's no Gaming mode as such but I understand that latency is slightly lower than previous models. I notice they have added the following to the brochure (available soon) "Additionally, as the amount of picture delay is very limited, D-ILA projectors are also well suited for playing video games."


2. Any chance the masking range will be increased enough to mask a variable aspect film for people doing the zoom method? I would think this would be an easy tweak to the JVC custom masking since they just need to increase the range, but maybe it is not that easy to change this for some reason?


I don't think this is possible, but I'll ask next time I speak to my contact.

So it looks like we have another wait and see "how much if any improvement" issue to test when we get a production model to play with. I further asked if there were any numbers he could find out for us as far as how much they have supposedly improved things from 80ms, so we will see if he can by chance get any info. If JVC truly improved this, you would think they would advertise it so I have my doubts. It would be good to know though since this could be a potential buying point for some vs going with a competitor IF things are improved to a significant degree. Gary did say slight improvement though, so chances are it is not enough to matter to those who care about this if there is any improvement at all. Who knows.

The material I've read indicate NO motorized Lens cover.

I guess JVC is really trying to kill the resale value of our RS-45's...

How about Clear Motion Drive for Sports? Not seeing it mentioned. Even the entry models have that correct? I thought I saw on one of the models only 2 modes offered now. Didn't they used to have 4 ? not that I cared about the black frame insertion and other one, just last two.

The 55 and 65 are going to take the biggest hit.

I sold my RS50 for more than that last year,after the new models were already out. Not everyone is on AVS, there's plenty of folks out there not ready to jump on the latest devices.

The fellow that bought mine read good reviews of the RS50 and wanted one.

I agree though, It's time to sell now.

I will wait to see what all comes out and then wait for the JVC B-stock units, I get the Darby in a couple days and I'm not ready to spend that kind of money on a PJ yet.
Heck, I've only got 600 hours on the RS-45 and only owned it less than a year. I'm still going to be keeping my eye out for newer DLP projectors and see what hits the market.

We'll be saying the same thing next year when the true 4K comes out.

I'd like to see if I can tell the difference between the 48 and 56 in my setup. I'm blacking out my ceiling and carpet in front of the screen in the next few weeks to prepare for the new models. With the 2.8HP I can crank the iris way down and it still looks nice and bright.

I'm curious to see the 3D as well.

Well that page also shows this:

And all these profiles are not included in the 4810 and that's been confirmed with Japan by GaryB.

I'm not sure which should not be there but there should only be 3 (and probably with different names). The RS4810 has the same color profiles as the RS46.

Edit: I'm sure the Adobe RGB mode, and the Cinema modes are incorrect. I'd also guess the film modes and anime modes and Vivid are not included in the RS4810 as all these use the switched in filter.

I believe the RS46 and 48/4810 will have the same (or similar) modes as the RS45....(Not sure what they're called but they are in essence: Rec709, Wide, 3D)

Woohoo for a motorized lens cover!

I am cautiously optimistic about the 3d improvements just as Toe is. I'll wait and see before i believe it. For my taste I'm not sure if eshift2 justifies the extra cost. The pre-order price on the RS46 is the same price as last years pre-order price for the RS45. If the 3D is improved I'll likely sell my RS45 (which now only has a couple of hundred hours on it having had no issues with my unit) and upgrade to the RS46.

Does CFI now work in 3D? When you get used to using CFI on 2D material it's a little distracting without being able to use it in 3D.

Also, regarding flicker I don't think I notice it as much as I would have about 4-5 years ago. Can the glasses used affect this at all? When I put my Xpands on I can see constant flickering for about the first 5 minutes of usage but then it levels off after that. I'm not sure if the shutters are opening and closing faster or if my eyes adjust after so long.

No CFI/CMD in 3d.

Guys, hold the presses.............I just found the biggest new feature yet........ready?

ADVANCED 3D CROSSTALK CANCELLATION CONTROL!!!!!


http://pro.jvc.com/prof/attributes/features.jsp?model_id=MDL102175











In all seriousness, looking at the RS46 info here...........

http://pro.jvc.com/prof/attributes/features.jsp?model_id=MDL102177

We have "upgraded 3d crosstalk cancellation circuit"

So I assume that the upgraded circuit is just another way of saying upgraded cancellation control which is what is in the 48/56 marketing info? Now my question is this.......Is the supposed crosstalk improvement based on this? Please tell me there is more to the supposed crosstalk improvement than a "upgraded" version of a 100% useless feature which still will make the upgraded version useless? Is this what the "new 3d chip" is going to bring to the table?

Is JVC really marketing an advanced version of the infamous crosstalk canceler?

There isn't much to go on yet, but this did seem like a good start if it's true

http://www.trustedreviews.com/jvc-x55-and-x95-projectors-first-look_Projector_review

Talking of 3D - witnessed here with the fairground scene of Despicable Me and How To Train Your Dragon - other seriously welcome discoveries were that JVC has shifted to RF for its glasses, utilising glasses with bigger lenses, and, best of all, seems to have really reduced crosstalk versus JVC’s current models.

obviously this doesn't speak for the flicker. They've known about the 3D criticism for 2 years now, I wouldn't be surprised if they found some way of improving it this year. If it matched the HW30/VW95, that would certainly be better than what we have today.

What were they comparing to though? A JVC with 300, 400 or more hours where maybe the crosstalk had actually increased? What scenes did they compare? It is just too vague to put any weight behind for me at this point. I am dying to see the Grand Canyon tree scene, Despicable Me lamp post, etc.....like we did last year which should be very telling as far as any real improvement or not. I cant get excited about these reports though all things considered.

It would be great if its true and I sure hope it is.

On my RS-45, I'd say the crosstalk quadrupled between 100-600 hours on the lamp. The biggest change was between 400-500 hours. Before the lamp made "Crosstalk Gone Wild...", I was almost thinking that in some movies you guys were being too picky, but probably because i watched some movies on a brand new lamp whereas some probably saw the same on an older lamp.

On another topic guys, I think I can safely say that the RS4810/48/X55 will have the new upgraded wire grid polarizer like the RS56 and 66. The RS46/X35 however will NOT have the upgraded wire grid polarizer.

On JVC's website, assuming that it is accurate, in the technical description for the RS4810 they mention: "The DLA-RS4810 is built around a newly designed optical engine with even higher contrast than previous models. An upgraded wire-grid polarizer reduces stray light caused by reflections and helps increase the native contrast ratio to a stunning 50,000:1 --the industry's highest."

When you go to the technical description of the RS46, there is no mention of a new upgraded wire grid polarizer. Obviously, since its not mentioned it doesn't have it.

So there we go, assuming JVC's official website is accurate, we now know the answer to that question.

I'm not so sure, since the 46 has the same CR spec.

This is EXACTLY why I cant put any weight behind these impressions of the new models when people claim the ghosting has improved from the current gen. The last 2 gens get WORSE as the lamp ages which many of us can attest to. The only fair comparison is to put both in the same room, new lamps, same material and go from there. Even then it wont be perfect since there could be sample variance. Not to mention we heard all this last year as well. Not saying it definitely wont happen, but until the Zombie report where we can compare with what we learned last year, nothing can be brought to the bank so to speak.

I experienced the same thing Coderguy on my 45. Somewhere between 300 and 400 hours ghosting went from bad to horrible. Cant say on my 45 since I stopped watching 3d long before that and I now have a new lamp from when I sent it in for service so I cant test it.

I doubt they did much to improve cross talk in the panels but it seems logical that the new bulbs may prevent the degragation issues? With out increasing the panel speed how much could they reduce cross talk? But it seems to me a lot of users think 3d is fine on a new bulb so if they fix the bulb issue and that keeps the 3d performance stable through out the performance of the bulb then it might be enought to sastify a large percentage of users?

I hope you're right about the 1/16th pixel adjust . Their plaque shows one thing and their Web Site shows another .
