    JVC 4K E-shift & UHD?

    I guess I should have learned something by now because whether its HIFI or AV, there is always someone who thinks that if they cant get spectacular results from a new format then no-one else can and the format is nothing short of a world-wide confidence trick. I dont' bother talking to people dissing DSD anymore but hopefully most Home Theatre enthusiasts will be able to exploit the benefits of what 4k UHD has to offer, although we might have to wait a while until the genuine 4k discs outnumber the fake (upscaled) ones.

    You made it relevant! You talked about a filter being put in place with massive light loss. There is no filter cutting in, and no light loss. As for the rest, you have seriously misunderstood what was happening and how it played out. I would ordinarily enlighten you but it seems you don't want to know about any situation where BT2020 will look better than BT 709. Your loss. The pixel size for true 4k is a fraction of what it is for 2k panels so you will never know the true capability of the format as far as resolution goes. But I think we have now finally arrived at the real issue . That is, you dont want anything better than what you have, and that is fine by me.

    Wrong yet again! - please stop assuming things. I have a Sony VPL-VW760ES and there is ZERO light loss when changing from BT 709 to BT 2020. I dont have a 150" screen and I don't recall you asking me about seating distance. A couple of issues here. Firstly , there are those who process their 4K signals and attest to improved image quality with their projectors. If you are looking for which format can give the best PQ, you need to optimise both. Secondly, your PJ is not ideal to decide such things, as you must know. It is important for observers to understand this in the context of your statements.

    Wrong again! - I saw Bt2020 cut in and out while receiving a 4k signal. It is clear you have a lot to learn. Don't be a tosser. You had previously made some valid points about the difficulties in achieving good HDR performance from projectors but that has turned into a complete bagging of the entire UHD format and anyone who disagrees with you. Look around you, you are on your own. While your convince yourself that your convoluted solution is just as good - like a bloke I knew who thought his modified Holden ute was as good as a stock Porsche - you also pretend to, or otherwise misrepresent the differences in resolution and colour depth. I don't think for a minute you are being genuine about this, just argumentative. Your projector is hopelessly inadequate for the task at hand which really makes your comments about 2 and 4k simply baseless diatribe.

    WRONG - it was the same material displayed with and without WCG Irrelevant - this is a discussion about universal video formats used around the world, not about modification to only one of the formats. And there is no guarantee that it would not look worse for many viewers. The differences between 2k and 4k on a native 4k projector are so bleeding obvious and significant, they even hit the most casual observers straight away. There is nothing subtle about it. An older JVC projector will give one of the worst 4k pictures possible compared to native 4k and other newer PJ's.

    Pixel mapping HDR to an OLED display gives a better chance at accuracy for dynamic range. I dont know of any projectors that do this with HDR. I am certain it was due to wide colour gamut and as it turned out it was the perfect way to compare. Leaving aside the 4K vs 2k discs, which I think are enough in many cases to demonstrate , on more than one occasion I have been streaming a 4K show from Netflix and due to the wonky internet connection it often starts out with "standard " 2k resolution and colour gamut but as things improve, it kicks over into the full monty. It is definitely a great picture to start with but the extra colour depth and graduations of colour shades are clearly noticeable when BT2020 was being received. Why are you sceptical that people can perceive the difference? I thought it would be obvious to most. You should never assume. Crude as it may be, I have done a fair bit to reduce the variables for the comparisons. My comments about the 4K discs relate to those that those that were mastered in 4K , not 2k masters upscaled. With those, I probably will stick to the 2K Blurays based on those that I have had experience with. The simple truth is genuine 4K material with my setup has clearly superior resolution and when fully exploited by the director/cinematographer also displays superior colour depth.
  7. I dont know if we should be discussing pricing here but I received a quote a while ago from a local retailer in Perth which was closer to $5k for the 8805. You can PM me if you want more details.

    Having compared some 4k movies to the equivalent 2k blurays, I can say that I generally prefer the 4k discs. There does appear to be more dynamic range with HDR - subjectively anyway. - which is what really matters to me. So I guess its best not to get hung up about theory of projector limitations and just enjoy.

    I think the way a lot of movies and TV shows are shot ( e.g. night scenes ) wont show wider colour gamut at its best but having seen it done well, ( and yes it was under sunlight) I am a believer! I was referring to the pixel mapped display ( OLED) having a greater dynamic range than no-pixel mapped displays
  10. I have no idea - please do tell.
  11. A quick comparison of Australian vs USA pricing for the Marantz AV8805: Australian RRP including 10% GST $6730 USA MSRP: $4500 USD which is $5965 AU Add State Sales Tax (around 9%) 537 total $6506 Not all US states have retail sales tax but most do.

    OK, so in summary, and if I am understanding this correctly : 1. Previously TV's were built to produce around 100 nits which was sufficient for displaying SDR material. To display HDR material, they must be capable of producing around 1000 nits for the HDR 10 standard. 2. With TV panel displays that have individual pixel mapping, they can achieve the contrast ratios required between black (pixel off) and the brightest part of the picture . 3. Projectors do not have individual pixel mapping and the dynamic range is therefore limited by the contrast ratio of the projector. Projectors do not have the required lumens to generate 1000 nits but since the dynamic range is limited to the underlying contrast ratio anyway, any image over 100 nits will be at the expense of brighter blacks. 4. Because of this and to get a watchable image for projectors , HDR encoded discs need to be effectively remapped to SDR . The Case for 4K UHD and Projectors There is still a case for watching 4k UHD discs with projectors . As I see it this comprises of: 1. Wider colour gamut - This does provide more visual depth for material that uses it properly. Its a waste for movies like "The Post" which deliberately use a muted palette for presumably artistic effect. But for movies and shows that do it properly , its definitely worth having. 2. 4K resolution - For genuine 4K movies like " Murder on the Orient Express" the extra resolution and rich sumptuous colours projected on to a big screen is really something . In fact the resolution in particular is more noticeable on bigger screens than on TV panels. 3. HDR - While projectors cannot display true HDR, a well executed remapping of HDR to SDR will provide an excellent picture that also allows you to take advantage of the wider colour gamut and higher resolution. In fact if the HDR to SDR is executed properly, the resulting image should be demonstrably superior on a big screen that the equivalent 2K material.

    I think we have examples of HDR being created through remapping of SDR material in the form of UHD discs that are simply upscaled 2K SDR versions. There is no HDR to start with so it must be created from SDR.

    Are pre amps required?

    You are assuming that all DACs are perfect sources capable of delivering the same dynamics and with less colouration as a decent preamp will - they hardly ever can unless you move into DACs with more highly developed analog stages ( built in preamp)

    You are assuming that “ no preamplifier” will result in an ideal sound - that is simply not the case.
