Digital Hi-End Projectors - $3,000+ USD MSRP > QUESTIONS YOU WOULD LIKE ASKED JVC AT CEDIA ABOUT ITS NEW 2013 PRODUCT LINE
mark haflich's Avatar mark haflich 10:18 AM 09-23-2013
The title says most of it. Of course, until the new line is announced at Cedia Thursday morning and the details released and posted here, it would be next to impossible to formulate questions about the line. Please no questions about problems in the past or why no true 4K consumer projector, if there is none.. I am a big closet fanboy of JVC and its east coast sales organization and would like the questions here to be completely non derogatory or critical. I will try to post the brochure or specs and line up if I can grab them from somewhere after release on Thursday morning. I will then collate and post in this post the questions. A volunteer is needed to ask the questions and guidelines foir an appropriate volunteer and expected conduct appear in the similar thread I started for the Sony 500/600ES.

Do the new models have a game mode?

Has the lag time been improved over last year?

Are the chassis the same as last year?

Has the cooling flow been modified from last year?

Do JVC's engineers feel there is still some significant potential left in LCOS, such that we might expect large improvements in contrast in the future? Or are they investigating next-gen projector technologies to move forward with picture quality (aside from adding 4K resolution)?

What meters may be used with auto cal?

Is clear motion available when displaying 3D?

Is there a colorspace in all models wide enough to encompass Rec709?

Will models with a UHD input be using HDMI 2.0?

Will models with a UHD input be HDCP 2.2 compliant?

Will inputs at 1080p or lower support bit rates higher than 8?

What exactly is your intelligent iris? Is it a dynamic iris?

Can you give a metric or numeric valuation as to what constitutes an "extremely improved dynamic range?" Can you explain this in light of the contrast numbers in the specifications? (They are not available yet). How was the extreme improvement in dynamic range achieved?

Are there any changes to 3D from last years models (i.e.,brightness, flicker, frame interpolation)?

Is e-shift available in 3D?

Is there a new e-shift element this year. Are there new e-shift algs this year and if so, can you describe how they changed or were improved?

Thanks Mark. One question I have is if there is a game mode and/or if lag time has been improved? I will ask myself if I go to the show, but not sure if I will make it or not.

I would like to have them being able to use a i1pro or a D3 with the auto cal

Clear motion in 3D, along with eshift
blee0120's Avatar blee0120 12:09 PM 09-23-2013
A gaming mode
GoCaboNow's Avatar GoCaboNow 02:17 PM 09-23-2013
Are these in the same chassis with same air flow layout?
mark haflich's Avatar mark haflich 02:19 PM 09-23-2013
Questions please all. This is not a wish list thread.
blee0120's Avatar blee0120 02:34 PM 09-23-2013
Oops. Will there be a game mode? Will other meters be included in the auto cal? Will clear motion be available in 3D? Will eshift be available in 3D?

Is the intelligent iris a dynamic iris? An 'extremely improved dynamic range' is advertised, yet the contrast numbers have barely budged. How is this improvement achieved? Is there any changes to the 3D from last years models? (brightness, flicker, frame interpolation)

is the e-shift element a carry over from the current model or a new design? There was a change from GEN 1 -> GEN 2
Geof's Avatar Geof 03:23 PM 09-23-2013
1) Are the colorspaces in all models wide enough to encompass Rec709?
(Many X55's have an issue with Green [and cyan])

2) If the projector accepts 4K inputs are the HDMI inputs using HDMI 1.4 or HDMI 2.0?
3) Will these "4K projectors" have a Rec2020 colorspace?
4) Will the "4K projectors" use HDCP 2.2?
5) Will the "4K projectors" process 10 or 12 bit color (or is it limited to 8 bits)?

Hey, I've got a lot of questions to ask JVC. Starting with this old philosophical head scratcher:

If a man speaks in a forest and there's no woman there to hear him, is he still "wrong"?


Wait...you mean about there product line! Sorry. Never mind...

How about:

Do JVC's engineers feel there is still some significant potential left in LCOS, such that we might expect large improvements in contrast in the future? Or are they investigating next-gen projector technologies to move forward with picture quality (aside from adding 4K resolution).
Toe's Avatar Toe 03:41 PM 09-23-2013
Rich, I think the answer to your first question will depend if the JVC rep is male or female.

Please review the questions posted in the first post and suggest any needed changes.
blee0120's Avatar blee0120 04:24 PM 09-23-2013
Definitely does it support bt. 2020 and do it downscale 4k to 1080p, then apply eshift. Will they use two hdmi cables to do 4k60 still?
mark haflich's Avatar mark haflich 04:24 PM 09-23-2013
Remember a volunteer is needed to ask the questions at Cedia and then to post the answers. I will not be there to do it. If no one volunteers, I will delete my post on Weds night.

E-shift when UHD is inputted would extract or create two different 1080p frames and then shift one of them. Can you refine the question or are you asking them for verification?
blee0120's Avatar blee0120 08:10 PM 09-23-2013
Some were speculating that they would not downscale the image to 1080p then up to 4k eshift. I assumed they would have to
mark haflich's Avatar mark haflich 10:12 PM 09-23-2013
There is no down scale from upscaled to UHD or native UHD in. The idea is to extract two different 1080p frames, perhaps processed to make it appear to your eyes when flashed sequentially and overlapped b you were seeing 3840 x 2160 pixels. If this were not the case, why would JVC as they have stated would they even bother upscaling a 1080p frame to UHD?If you frame some sort of precise question, I would be glad to add it to the list. Perhaps, with a native UHD image or a lesser resolution upscaled to UHD, what does the sampling and processing portion of the E-shift process do to create the two 1080p sequential frames? Edit as you like or suggest a better question and I'll add it.

Volunteers have been found for the two Sony question threads. No one has come forth for this thread.

Looks like no one is volunteering. Its a real shame there is a thread participant here that lives very close to the convention center. And he doesn't even need a CES Expo pass because the JVC Professional Display is in a hotel one block from the convention center. I guess that individual has more important rows to hoe. What name rhymes with Hoe?
mark haflich's Avatar mark haflich 07:01 AM 09-25-2013
Today I have modified a few of the questions. Obviously, the JVCs do not support the ITU2020 color space. No technology today can support that color space. HDMI 2.0 supports bit rates higher than 8, and chroma sub sapling better than 4:2:0 at 1080p and less resolutions. It does not at UHD. What this means is that HDMI 2.0 allows for much better let's call it 2K and less than we have today but only relatively low quality UHD or 4K than we could have.

LOL! Sorry Mark, but if I knew FOR SURE that I was going, I would be MORE than happy to ask these questions and report back to you guys. I am just not feeling any need to go this year from what I have heard of the new models combined with my lacking "fun money" right at the moment. There is really nothing I need to see at Cedia this year in light of that most likely so I don't want to commit to this when I most likely am not even going to the show. I am guessing next year will bring more excitement (I hope) and hopefully deeper pockets on my end! tongue.gif

It does not appear that anyone is willing to do it. So there is a need for you to take one for the team. Since its a VIP room, you or anyone else will feel automatically elevated to rock star status. There is usually a free gift and food. Do I have to arrange an exotic dancer or message lady and pay for her in order to get you to do this? smile.gif Think of the fame you will have among forum members for doing this. I'll even give you a thumbs up.
Craig Peer's Avatar Craig Peer 10:22 AM 09-25-2013
I'll take the list minus question 5 and see what I can get answered.
mark haflich's Avatar mark haflich 10:50 AM 09-25-2013
Fair enough. Some folks at JVC are very critical of sales people, who sell JVC, who make any comment they construe as critical. Believe me, I know. And I like their products and their company. So be sure to tread lightly. I have tried to construct a list of questions that are not hostile, and most were not been suggested by me. Give you know who my regards and my hope that they have a great year.

Thanks Craig! Mark ALMOST had me convinced to go down there. Hell I even signed up for a pass at Crestron! tongue.gif I think it was the Exotic dancer talk that convinced me. If for some reason you cant make it, I will do it.
mark haflich's Avatar mark haflich 11:51 AM 09-25-2013
Toe. You ought to go anyway. I have gone to many many Cedias and there are always great things to see and learn and you get to meet fellow posters. Its all good. And there are prize drawings that you can enter at various booths.

And there are booth babes who are paid to smile at you and make you feel welcome no matter how nerdy and ugly you happen to be. smile.gif

Not to be a buzz kill or anything but I imagine most of these questions will be answered by default by the press conference in the morning with the info WIDELY available. JVC typically does a very good job with their info at the shows including technical diagrams of any new tech they come out with. But most of the questions are so generalized that I can't imagine anyone will actually need to ask JVC any of them, the info will be wide already. Same goes for a lot of the Sony questions.

Thanks for the insight. I guess you won't be giving my posts a thumbs up?
