    At garantien ikke dekker feil som oppstår pga en har rotet til firmwareoppdatering er noe helt annet enn at en mister garantien på hele produktet. Dette høres fornuftig ut.

    Takk for oppklaringen.

    Detaljer i det sorte på HD1

    Jeg har veldig lyst til å kjøpe denne, og så nettopp prosjektoren med Pioneer sin nye Bluray spiller i 24P. Så på James Bond Casino Royale, og bl.a. på scenen på terrassen der James Bond ønsker mere penger fra Vesper. På en scene hvor han står med ryggen til kamera, og du ser hele dressjakka hans.

    Der var absolutt ikke noe annet enn sort der jakka hans var, ingen detaljer i det hele tatt. Det er mulig at sort nivået var stilt for lavt på denne, det vet jeg ikke, men jeg stusset litt. Har noen av dere som har denne noen kommentarer til detaljeringen i det sorte?

    Det er garantert noe "galt" med det oppsettet du så. HD1 er helt i toppen når det kommer til gjengiving av detaljer i det sorte.

    Det finnes vel strengt tatt ingen annen projektor som kommer i nærheten på akkurat dette området. Sharp XV-Z21000 er vel tettest på, men da har du til gjengjeld ingen dynamikk i lyse områder.

    Det var beroligende!
    Mente også det var en av styrkene til denne prosjektoren.

    Takk AK og Gorm.

    JVC EXPANDS REFERENCE SERIES PREMIUM DISPLAY LINE-UP

    The new accessories include the RSVP1 Video Processor, manufactured by DVDO, and the RSAL1 Anamorphic Lens system developed by Panamorph.

    Certified for top quality performance and compatibility, these new accessories provide expanded capabilities in demanding custom home theater systems. For example, the RSAL1 enables projection of a 2.35 aspect ratio image using all 1920 x 1080 pixels of the Direct Drive Image Light Amplifier (D-ILA™) projector. Constant screen height is provided when displaying 16:9 images.

    JVC’s D-ILA™ technology is an advanced form of Liquid Crystal on Silicon (LCOS) that is capable of greater pixel density than competing technologies such as DLP or LCD. The RSVP1 Processor is an advanced signal hub that allows a variety of HD and SD input sources to connect to the D-ILA projector with a single cable. Additional signal processing circuitry is provided to allow for custom settings provided by the installer.
    Høres ikke ut som om den eksterne videoprosessoren RSVP1 kommer til å gi de kalibreringsmulighetene som var ønskelig. Er da en Crystalio2 det beste alternativet?

    RSVP1 er en "rebadged" DVDO VP50, og støtter ikke justering av primærfargene. Det gjør dessverre heller ikke CII (enda i hvertfall).

    JVC har sagt at de kommer ut med en prosessor som skal kunne gjøre dette, til en rimelig penge, men den er enda "in the works".

    Litt info fra en amerikansk site som under Cedia snakket med en av konstruktørene til HD100/RS2.

    The JVC Update

    As an installer-focused show, we mostly encountered sales and marketing types, who gave us fluff answers to our questions and usually didn't even know the specs of the product they were trying to sell. There were a few exceptions, one of which being JVC, who allowed us to sit down with Gary Klasmeier, the Product Engineering Manager for JVC Professional Products including the newly announced DLA-RS2.

    Sitting down with Gary we were able to get much more detail on the RS2 and how it differs from its predecessor.

    Typically, a projector will take around 18 - 24 months to go from brainstorming a model to release. With DLA-RS2, a number of items were borrowed from the RS1 design, such as the case, thus allowing for a shorter design cycle.

    The RS2/HD100 projectors that were at CEDIA were only about a week old before they were brought out to the show, they were in all senses of the words: engineering samples. The next step for JVC are pre-production samples, these ones will be used to figure out exactly what needs to be fixed/changed before going into mass production. JVC is expecting the first pre-production samples back by the end of this month, at which point he will have a better idea of when the final shipments will go out.

    Right now JVC is targeting late November for the release of the DLA-RS2 and DLA-HD100, a stark contrast to Sony's immediately available VW60 but potentially worth the wait.

    Color Accuracy and Adjustment

    With the RS2/HD100, JVC has added a number of color and gamma adjustment options that weren't there in the RS1.

    The OSD menu offers RGB adjustment at several points along the gamma curve as you can see from the picture below:

    You can also now individually select gamma correction values instead of having to rely on factory presets.

    Improvements: RS1 vs. RS2
    The JVC DLA-RS1 was widely regarded as an excellent LCoS projector at its price point, so we wanted to know what had truly changed between it and the new RS2 resulting in better specs and a higher price.

    The RS2 primarily uses improved LCoS panels, reducing stray light within the panels themselves, and thus improving contrast ratio. Much like CPU and GPU manufacturing, when producing LCoS devices, JVC can learn a lot about tweaking its production to result in improvements to the chips. In the case of the RS2, JVC was able to improve the surface uniformity of the LCoS panels and reduce the space between pixels.

    The less uniform the LCoS surface is, the more variance there will be between phase angles of the liquid crystals on the chip, resulting in stray light especially if they are all supposed to be angled the same for example in a totally black portion of a scene. Flatter pixel surfaces and smaller pixel gaps allow the liquid crystals to all stay in the same line and keep the same phase angles, giving you improved contrast ratio.

    Other improvements to the display engine included changes to the color filters; by narrowing up some of the color filters in the RS2, JVC was able to reduce stray light which also contributed to the increase in contrast ratio.

    Although the lens is different from the RS1 to RS2, it appears that there are no visual benefits to the new lens. JVC simply went from a manually operated lens to a motorized lens.

    JVC on 2.35:1
    JVC is one of many companies offering the Panamorph UH380 as an option for 2.35:1 setups, we asked Mr. Klasmeier why JVC didn't simply produce its own 2.35:1 lenses, ideally at more affordable price points to better service the needs of the consumers.

    From JVC's perspective, the fact that it is even offering the UH380 as an option is a huge step forward. The success of the UH380 option will really determine what JVC decides to do in the future, but as 2.35:1 setups become more popular you can expect manufacturers like JVC to begin considering marketing and selling their own anamorphic lenses.

    Noen som vet om man kan vise 120hz bilder på HD1? Eventulet hvilke projektorer kan det?

    VW200 skal klare det, men jeg vet ikke om noen andre for øyeblikket.
