Offical JVC DLA-RS4810 Owners Thread

Got a call from Michael today. Great pre-order pricing as usual. I am on the 4810 and 56 pre-order list. so i have to decide if the 56 is worth the extra $1500.

Please give Mike a call. I have departed AV Science and do not know the pricing AV Science is offering on the JVCs..

Sorry to hear that but now you can kick back and enjoy your Sony!

So, given that you're independent again do you have any thoughts about how an RS55 vs RS4810 would compare PQ wise?

For anybody who is interested, it is officially confirmed per GaryB and Steve Carter over at AVforums that the RS48/4810/X55 will have convergence correction of 1/16th pixel increments.

I am thinking hard between RS4810 and HW50. Is the HW50 brighter and have higher ANSI contrast ?

I don't know, but that is the answer that I got. 1/16th pixel increments. Hopefully that will stay.

Sorry if I missed.....can the previous IR system emitter and glasses be used with the 2013 JVCs?

I know the 2013 RF system can be used with the 2012 and 2011 models.

Is it true that the 4810 comes with a spare bulb? Or am I making that up?

Yes, that is true

Not true in the US (might be true elsewhere).

Looks like the 3D is improved from last year:
http://www.avforums.com/forums/avforums-news-notices/1678352-exclusive-jvc-launch-dla-x35-x55-x75-x95-projectors.html

In the remarks on the AV Forums with that review the question came up whether or not the X55 / RS48 or 4810..... has a "dual" iris same as the higher 2 models. Hasn't been confirmed yes or no over there yet. Anyone here know?

That site gave us the same story last year (including supposed improvements in their review as far as 3d) and it did not happen. I am not counting on anything until Zombies review.

I don't blame you for this opinion based upon last years JVC amateur 3D review.
But the reviewer came clean:
" I have been using an X90R, on and off, for a couple of months so I am used to the performance in 3D. Steve Carter, product specialist for JVC UK confirmed that there was a new 3D chip inside the unit and that the engineers had been working hard to make sure there was a noticeable jump in quality, especially with crosstalk performance. We would agree with that assessment on the showing here where crosstalk was almost non-existent and only seen in those most-difficult-of-scenes we all know, when we went looking for it. Even then when it was seen it was mild and on the same level as some of the better competition out there. "

Now the two product managers from Japan were there showing difficult 3D scenes. If they both are making questionable remarks again, then i too will join the ranks of those cynical of JVC. I've been able not to have any skin in the game. For some reason there is a $400 penalty if you purchase after the first shipment. If JVC does not send samples to reviewers before release, then that will make my decision all the easier.
But in the meantime I'll keep an open mind!

I can't say for sure, but I highly doubt they are going to include the dual iris in the RS48 / 4810.. they would be giving away too much on the lower cost model.

you'll find out when I do.. I'm going to see at least 2 of the new models including the RS56.

I would agree that it looks encouraging, but again it looked that way last year as well. Last year was the crosstalk canceler which was/is 100% useless........this year a new chip.......will it actually help to any significant degree with the same 120hz? After everything I have read and experienced myself with the RS40 and RS45 I just cant be anything but VERY cautiously optimistic at best. The other thing is a significant improvement is subjective depending on who you ask. Last year I believe it was this same site that was hyping up how the Tangled lantern scene no longer showed ghosting on the 45/55/65 prototype models while it did on the 40/50/60 production models! That may or may not have been true since I dont have that disc to check, but I can tell you all my others discs that ghosted on the 40 ghosted just as much on the 45. What might be significant to them might be minor to me or someone else......hard to say. I also wonder how many hours were on the X90 he was using? If the hours were racked up to the point that the lamp has dimmed, there is a good chance that the ghosting had increased as is known to happen with the JVCs as the lamp ages, so of course the prototype models would look better with ghosting. All this is why I will remain very skeptical until I read a report from someone I trust (like Jason). It would be SO awesome if there was significant improvements in 3d and man do I hope its true..........Jason hurry up and get a unit to review and lets throw Grand Canyon, Patagonia, DM, etc.......at it and really get the scoop!

EDIT: $400 penalty if you purchase after the first shipment?

I am sure you guys know better than me, but I thought the big reason for the dual iris was for increased contrast in the upper models? If so, I would not think the 4810 would have the dual iris since it "only" has 50,000 native, same as the RS40/45/46 and the dual iris is not needed. Is there another purpose for the dual iris above and beyond more contrast?
Edited by Toe - 9/20/12 at 4:36pm

Yeah that was me that asked Gary and I would have been shocked had he said yes to a dual Iris (although he's confirming his answers with japan).

The other question I asked Gary was about profiles. I find the fact that the RS48/4810 profiles are similar to the RS46 profiles very encouraging. The RS45 has a wide enough gamut to be fully correctable using the Lumagen 125Pt cal (Tom Huffman told me his RS45/Lumagen setup is almost perfect after the 125 point cal). The fact that JVC says they've widened the profiles this year is good news too and I suspect an SR4810/Lumagen combo will be a tough combo to beat but time will tell the tale.

I need to go over there and post a few questions. 2 things I am curious about.......

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?

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?

EDIT: Just posted these 2 questions over there and if there is any info to be had from it, I will link it here for anyone interested.

The other 3d issue that is strangely not being talked about in these first looks is flicker. When I say strange, I mean not at all I am sure nobody wants to bring this up because I just dont see any way with the current tech that this will be improved.....at all. If you are sensitive to flicker, the JVCs are reported to be the worst. I am finding flicker almost as distracting as ghosting on my 45 at this point! Also, since the 3d is reportedly brighter, this will make flicker even more noticeable unfortunately.
Edited by Toe - 9/20/12 at 6:05pm

you only have to wait ~ 10 weeks to find out.

OMG.............that is WAY to long!!!! Hopefully it goes quick though!

Thanks for the confirmation SOWK.

i'm on the pre-order for the 4810 and this will be my first 3D projector. What is the cause of the flicker? The glasses?

FYI, GaryB has confirmed with Japan that the RS46 and RS48 have the same color profiles and neither have the dual iris.

Personally I wouldn't miss all the color profiles in the higher end models. I basically want just one Colorspace that is wide enough to allow for proper calibration.
