    gosh. Mine is going to be installed on Thursday 13th. I don't know yet if they will deliver it with the update.

    Surely just a matter of a phone call tomorrow to find out. It sounds like it's not firmware as such, rather one or more of the chips on a board need 'flashing'. I have to do this on some systems I work on (nothing to do with AV just a similar principle): We can update the firmware quite easily, but flashing the various PCBs involve a special cable and software to reprogram the PCBs themselves. It seems a bit odd that this could get through, but it's perils of being an early adopter I suppose, though I'd be more bothered if it impacted on 2D quality.

    As a side comment, I took my family to see Skyfall this afternoon. It was a near deserted cinema (it's been out a while now I suppose, but that was my plan to avoid a really busy showing) so that was good. It was a Sony 4K presentation and I have to say it was pretty sharp with good ANSI contrast, though the blacks in dark scenes weren't a patch on my X35 (or HD350 for that matter). I did notice that there was some slight judder on certain panning scenes, both horizontal and vertical, so I'll know that when I eventually watch it on BluRay I won't blame the X35 for that issue. :)

    Haven't put mine on today, but I might try some quick calibration later this week just to suss out which colour mode is best as a starting point. I could run an autocal as it's only 40 minutes or so, though I fully expect the lamp to drift. Got to sort out/find my black velvet side masking material to make something a bit better/easier to hang up in time for Christmas as I expect there will be plenty of TV sourced viewing, which means 16:9.

    Yes, must be a matter of flashing a chip, it can't be something else as they are specifying it requires a special cable connected inside the beast. Too bad, the seller is not working on Mondays.....

    BTW, if anyone is interested with a 3m39 base Lumene Multi Palace (new, never opened), there is one available at a very good price in Luxembourg. (screen with modulable panels from 4:3 to 16:9 to 2:35.

    And, as if by magic, he appears. I haven't heard anything about this, but I've emailed my contacts in Japan to ask if there is an update. I'll post here when I get an answer.

    Good to see you the other day callahan and thanks for your help :smashin:

    Glad you enjoyed the quick systems check with the X55 last week, look forward to seeing you again next month for the JVC Open day, I'll be busy researching over Christmas for some more reference demo material as I really should move on from Dark Knight now :rolleyes:

    Hi Kelvin, glad to hear that you are enjoying your X35, 10 hours in one day, that is going some :eek: I know the feeling though as I've been spending some quality time with my X55 over the weekend. Now I'm determined to not get sucked into the whole tweaking side as I know with my 750 I spent more time playing with the picture and building bat caves rather than watching films and it looks so good out the box I just want to enjoy it but I have to admit I've had a little play with the basic settings, I can't make my mind up on whether I prefer the Film preset or Cinema, as both have their positives and negatives, what is everyone else using? I think I'm leaning towards Cinema, these are my settings, for now, any recommendations appreciated -

    Colour Profile - Cinema
    Colour Temperature - 6500K
    Gamma - A

    Clear Motion - Off
    Lens Aperture - -6
    Lamp Power - Low
    Environmental Setting - ON

    Is anyone else using the environmental setting by the way? it defiantly seems to add more punch and richness.

    I had a quick look at 3D playback with Avengers and it did look pretty stunning, far better than the X3 demo I had a couple of years ago with no apparent crosstalk visible but I do think I'd struggle to watch a whole film in 3D as it just doesn't feel natural to me and to be honest I'm so blown away with the 2D performance, 3D just seems to ruin that experience for me.

    The real star though has to be eShift, this is my first experince of this technology, I have to say there must be some very clever people at JVC as it makes a pretty stunning difference, don't get me wrong, with it turned off the picture is still beautiful but once activated the level of extra detail and sharpness is a real eye opener, and somehow it still remains to look natural and not over processed, I've tried to capture the difference in the pictures below, not sure if it will work but thought it was worth posting anyway to give some idea of the differences -

    eShift off -

    eShift on -

    Actually it must have been 12 hours :eek: as I've just turned it on to warm it up for a very quick calibration tonight. I expect to change the colour temp to 'Custom 1' then I can tweak the 100% before running an autocal. :cool: As I remember spending 5-6 hours trying to calibrate my HD350 just doing some basic set up first, set up the meter and then pressing a button in Chromapure and come back 40 minutes later is such an improvement.

    I'm currently running the following:

    HDMI set to Super white to allow content over 235 to show.

    User 1 mode (for 16:9 content):

    Contrast, Brightness, Colour and Tint at 0
    Colour temp 6500K
    Gamma Custom 1 (set to 2.3 in it's own menu) as I suspect the A/B/C/D gammas are curves rather than flat.
    Advance menu: All at zero/off apart from colour space Standard & Aperture -15

    User 2 mode (for 2.35:1 content)

    As above, but with Aperture at -9 to maintain the same 94 Lux peak white.

    Just off now to do a basic 'as found' calibration check, then I'll run the autocal after once I've checked which colour space is the best starting point so my Lumagen can reign in the colours properly.

    I don't have any way of calibrating mine unless I paid someone to do it, is it worth it?

    Also could I just use your settings Kevin? or does the room play a bit part

    Not worth using my settings as I also use an external Lumagen video processor, so I chose the settings to give the widest starting point for the Lumagen to correct. Ive just run some starting point checks which I'll post up later to show the effect of the colour space choice at 75% and 100% measurements.

    The room, projector, it's lamp, screen and sources mean that it's really a waste of time copying settings. Far better just to use a set up disc to set up the basics which is all you can do by eye.

    Just running the greyscale autocal at the moment after adjusting the 100% white: I actually had too much red at 100% using the 6500K colour temp. I've selected a custom color temp based on 6500K with the red and blue pulled down about 11 points to give a dE of 0.4 at 100%. The rest is done by Chromapure/Lumagen.

    Wow, I thought 1080p was causing huge concern in Hollywood, wait until they see the details with e:shift, the pic of Heath Ledger is truly upclose and personal. Not sure I prefer it though. I must get a demo.

    Vipers, I don't suppose you could show some Eshift shots from Casino Royale as I don't have any Batman discs? I'd like to show how it looks via my Lens with Darbee on for comparison. :)

    Just re runing the autocal gamut 125 point. It took 20 minutes to do earlier :eek: , but I had the X35 colour space set to Standard, so I'm now trying with it set to Wide to see if there is any difference in results. It looks like the custom gamma set to 2.3 gave pretty good results. All I'd done was correct the 100%, plus contrast and brightness (and black level at +2). I'll add this to a later post to show other users what could be a good starting point.

    What I am pleased about tonight is that now I've calibrated I'm getting even more lumens which is unusual. :eek: I'd set up using 6500K and standard colour space all settings at zero. I've now lifted the main contrast to +5 as I don't mind clipping above 245 instead of going all the way to 255 (and not a hard clipping at 235 as some chose). Then the corrected 100% white balance is brighter than the default 6500K one. So after calibration my peak white is now just over 100 Lux up from 92 Lux when I measured immediately before the calibration started.

    I found that changing the colour space also effects the greyscale, so my second gamut autocal with Wide colour space wasn't any good (the 100% white dE became about 5). Still, all part of the learning curve, so I'm back to using the first autocal based on Standard colour space.

    Shame that the forum limits the size of the PDFs I produced of the different colour space gamut results pre calibration: I will post them over on the AVS X35 owners thread for those interested. ;) In the meantime here is the result of about 45 minutes 'work' including the basic adjustments and 100% white balance trim. Just the post cal results I'm afraid.

    Not bad at all for 45 mins work (work by the lumagen I mean while you sit and drink tea!)
    Seems like a fine piece of kit. So how is the image looking now?

    For basic setup you could use the AVS-HD disc available here, or the Digital video essentials bluray, or Disney WOW. The Spears and Munsil disc is also a good test disc to test the performance of the setup.

    These will help you set the basics, i.e. brightness, cotrast and sharpness etc, but anymore than this, and you will ideally need to invest in calibration equipment, or pay for a calibrator.

    I hope that helps.

    Well it was coffee I was drinking Soup. ;) But yes, a good result for so little time and effort. The picture looks great right now (though the OH is watching New Tricks at least it's calibrated and on BBC One HD :D). What I need to do is improve the room, planing to recycle my old 'bat tent' just for the Christmas period until I can do something a bit more stylish and slicker to put up.

    @ Scifi, Ricky has saved me finding a link, but that's the free disc I use for the initial set up of all my displays, even those not connected to my Lumagen in other rooms.

    Up to 18 hours already. At this rate I'll be upto the same hours as my old HD350 by New Year. :D I've been on Blockbuster tonight as well to add some extra discs to enjoy on the X35. :cool:

    Are you able to say that x35 has a real improvement over the x30? I still read that JVC did a copy paste...I can't imagine that !

    Well they didn't do a complete copy and paste because there is a different lamp and lamp power supply, which for me was enough to chose the X35 over the X30 due to the later's history of lamp dimming issues. Of course we don't know yet how the new lamp will hold out, but I've made a point of measuring mine (in the same calibration settings for consistancy) and will continue to do so over it's life.

    I've not seen an X30 in my room either, so it's hard to tell. I do have a very long throw setup which means I get maximum contrast and a very sharp image due to not using any zoom. Therefore seeing projectors side by side in my room is the only way I could be 100% certain of a difference. For example when I saw the X55 last week at Jagdeepp's place it didn't seem to have as much contrast as my X35, but they are specified the same 50,000:1. In Jag's set up there was full zoom applied and the iris was half open, so even his much better room the settings made the X55 look less impressive in contrast terms.

    Well it's reported that cross talk has improved so unlikely a straight copy and paste. That said, the early indications were that last year x talk improved but turned out not to be the case so hard to say for sure.

    Hi Gary,

    According to that link providing by HAWK-EYE link in post # 109 it advises
    quote “No X 35 with the firmware error are more delivered starting this week …The update is only via a special interface, for connecting the projector also must be opened. In other words: An update is possible only via the JVC service...No X 35 with the firmware error are more delivered starting this week “ Unquote

    I have a X-35 due next week, apparently there's a new shipment arriving in Belgium next Monday, will these be updated prior to shipping to dealers and how will the end customer know/be able to verify - maybe firmware version?

    Not sure on the technical reasons why, but I wonder if the JVCs seem to be bought by owners more interested in watching films than gaming (in general). They aren't usually as bright as some of the competition (though brighter than the supposedly very bright new Panasonic I notice having compared calibrated results elsewhere ;)) so maybe gamers tend to prefer brighter models.

    I understand it must be frustrating if you want a JVC for gaming, but I would hope that they don't compromise the great 2D performance for films in order to achieve this. Maybe this isn't possible for some technical reason, so they preference better film performance over lower lag?

    I agree with all of that. If it means sacrificing 2d performance and considering the JVCs are obviously geared toward movie watchers in particular, it is not worth it. I am still very curious why this has not been improved though as JVC is bringing up the rear in this area vs the competition. Is it that they cant improve it due to some sort of hardware limitation, or they just dont want to improve it and dont feel it is worth the time/resources? A fair amount of potential buyers are turned off of JVC each year due to this and choose to go with Sony or Panasonic, so it is definitely an interesting question to ponder.

    I've had a bit more info on the X35 update. I think some of the facts may have got lost in translation. It's not actually a fix for a problem, it's for an improvement in the 3D picture. It can't be done by the user as it requires a special jig and removal of one side of the cabinet to access an internal socket. This means the projector would have to go to our Service Centre in Norwich for the update.

    I haven't seen the difference it makes yet as I won't be getting my jig until next week, but I get the impression this is a tweak rather than something radical.

    As per JVC, it's clearly a mistake. The first models are with firwmare of the pre-serial, not the final. So....

    Well I definitely would want mine upgraded as bought it for watching 3D and watched Hugo in 3D at the weekend and noticed alot of crosstalk in certain scenes, is Hugo a particularly bad 3D film?

    Shame as mine has just been replaced due to a couple of dead pixels and now the replacement looks like it will be off for an upgrade.

    Any idea when these upgrades will start happening?

    Sadly, Hugo is plagued by crosstalk issues - whilst some parts of the film are sublime, there's some very noticeable scenes. The worst one that springs to mind is towards the end, with a transitional shot of 'the man in the moon' that turns into the moon in the sky - there's a lot of ghosting around the Moon itself. Also scenes with the automoton towards the close of the film have visible ghosting. These are thought to be content crosstalk rather than display driven (multiple devices, Panny VT series plasmas, Optoma HD33's etc all exhibit the same result).

    HTH :thumbsup:

    Testing is today, review will follow soon. I am sure people would like the full details and not a rushed review, so we have taken the time to put over 50 hours on the bulb as well.
    Steve Withers is doing the same on the X55 he has for review. If we can manage it as well, we plan a side by side with the X75 time permitting.
