    I thought TCL Chinese was the best HDR locally and maybe in the world (from SMPTE meeting held there when they got new projector)?
    How does it compare to the two you mention?
    Any site that lists projection tech by theatre?
    The Dolby 3D/HDR glasses are heavy is only issue I have had - would rather not feel them - gets a little distracting for long movies.

    Where you wear them on your nose will affect the feeling.
    Since when has denying that the possible is possible been reason? Such is the life of some skepticism.

    Normalcy involves what is realistically possible, not just what you say.

    THX has their thing. There is also UHD Alliance Premium Certified. Then again there is a THX certified HDR projector which would go against THX being the be-all-end-all or Stacey is ignoring $35k projectors :D.

    Big glass panels are selling so well I suspect the few CE companies with the right portfolio to develop a 4K projector have little motivation to risk development dollars. Add to that the razor thin margins in the display business these days, corporate risk aversion, etc.

    Thin margins on projectors?

    The difference between a 720p display and a 4k would not be much, nor too much between a cheapest model and a brand mid range. Even a branded higher LCD might be much more to the $700 no name set than the midrange IP licensing though, might sting, as all the advanced materials in there, even if moderately more expensive to manufacture, might have large licensing costs on the production pushing the price. Patents are bad, you can force payment to manufacture something, and force payment to use it in a product, even to import it into a country. Smoke and mirrors, manufacturers often use stuff these days of it is cheap. Not like the old days when the top end consumer was more cutting edge as well as costly and risky to put out. Now, in the 16k age, we still have 4k instead (yes 16k micro display has been done years ago, I was looking at it for a touch table projector).

    Actually, I believe the margins on most projectors are substantial. I was referring to the intense competition in the LCD flat panel space. The total revenue from projector sales may be limited by the relatively small number of units sold annually vs LCD panels. Furthermore, lower volume gives you fewer units to spread the NRE costs over, which also incentivizes slower refresh cycles. The big upside is that most projectors are sold into the high end HT market, education, corporate, etc where it's easier to ask higher price points.

    But LCD:s are misleading too. The price between a $300 andna $3k should be a lot closer. Called stratification, and is one of the tricks. If only there was three types per manufacturer Blair, things could he a lot better.

    Perhaps the question should start with what would the ultimate (home) viewing experience be - and work out what exists, and/or what compromises need work on?

    Q1) What screen size do people want?

    a) Small Screen : 80 inch diagonal (or smaller)
    b) Large Screen : 110 inch diagonal (or larger)

    My experience is that (b) is desirable as this increases immersion.

    Even when the 77LG OLED comes out - this (77" diagonal) will not meet this preference.

    The problem with a huge fixed screen structure, is that (at least in UK homes) bringing one into a house becomes impractical.

    Q2) If viewing in the presence of Ambient light is required - what additional requirements?

    PROJECTOR SCREENS:
    Projector screen materials reflect light and usually have image contrast is awful where ambient light is involved.
    Screens that are darker reflect less light .. but kill the maximum brightness of the projector.

    Novel Projector screen materials do exist that reflect three narrow bands of colour - and absorb all others.
    These look 'Black' to the human eye - except at the RGB colours frequencies (same as Projector primaries).
    These Do work in Daylight - however, the projectors are not currently created with these screens specific narrow band reflective frequencies in mind, and so there can be some colour issues. In addition white light Does still include some energies at all frequencies, and so Some RGB is still reflected.

    FIXED SCREENS :
    Many 2016 screens front material (ie glass) were not designed with ambient light reflection in mind (eg LG OLED) and added a visible TINT to their colours.

    Q3) NOISE / LIGHT LEVELS?

    PROJECTORS:
    LED light sources are becoming more efficient - but Laser light is currently inefficient.
    The most recent advancements in the creation of LASER light (that I am aware) is actually through modified Quantum dots (in which the shape of the outside surface is chemically made to look like the outside of an American football, but the inside spherical) - may end up with high efficiency solution - but not any time soon.

    Use of remote phosphor (shining blue light on a material on one side, and allowing the phosphor to radiate another colour) creates heat (both in light absorption and filtering).

    The project is that this does not SCALE very well. To create HDR images requires the ability to Punch out more light for the same size (volume) projector.
    If Lasers projectors are several times less efficient than LED - and pump out increasing amounts of light, they are not going to be quiet any time soon.

    FIXED SCREENS :
    The 'good thing' about screens is that that they have a surface area scales perfectly with size. Heat does not become more of a problem if dissipated over their surface area. Ultimately - these can be passive (quiet).
