    ok I have an opportunity of getting a LG 65ub9200 via a trade.

    I'm considereding it only because of apple tv4
    I have a very large HD movie collection via iTunes. First question I heared it would give us a free upgrade to 4K

    Second will we be able to down load 4K or just stream. I have a beautiful house out in country and don't see my self being able to stream but I can download at my office quick

    Also on either my iPhone iPad or MacBook Pro. I can't see any 4K content

    Not all of your HD films will be upgraded to 4K for free, only the ones that are available in 4K through iTunes. I have almost 400 movies in my iTunes library, and only 20 were upgraded to 4K when I checked earlier this week. So don't expect a 4K upgrade for every film you own. (Disney is not participating, for example.)

    I don't know about downloading yet.

    On Friday my iPhone showed several movies that I had bought were now eligible for 4K I checked on Saturday on the same movies and the 4K had been removed at least on my iPhone.. But on my son's iPad it still showed 4K for those same movies. So may be they are still playing around with it until, after the ATV 4Ks are shipped. That is just my opinion. By the way you have to check via iTunes and under "purchased" and then click on the movie you think may now may be 4K for it to show 4K or not.

    TV might not be a good idea as it's a 3 year old set. No HDR. It may be only HDMI 2.0, and there have been 2 updates since then (2.0a and 2.0b). The HDMI 2.1 spec has been released and hopefully will start showing up on products in 2018.

    I am not sure what version of HDCP it uses. There are known problems with HDCP 1.4 (you want at least 2.2).

    With outdated HDMI and HDCP there is a risk of compatibility issues which could result in the dreaded HDCP error.

    How would you plan to get your movies to the Apple TV? iTunes? Plex? I know of no way to download a movie to the Apple TV as the internal storage is small (particularly if you are talking about 4K movies). No way to connect an external disk. You'll have to stream.

    There are reports of problems playing movies loaded onto a USB stick connected directly to the set:

    My wifi router speed is fine it's the internet speed that hurts so if already downloaded locally I'm fine

    The set does not do HDR or Dolby Vision. I would pass. 4k alone on a set that old I snot going to make that much difference.

    If you can before you trade try it out with your Apple TV, or get a return option, just in case there is an HDCP problem.

    Apple have a note regarding non HDR/Dolby Vision TVs at the bottom of the ATV4K guide which says you may need to set at 1080p and let the TV upscale to 4K.
    I'm in this predicament myself as my Panasonic is a 2015 model that I bought just over a year ago which was slightly before HDR were being widely sold.
    I've decided to stick with my ATV4 for now.

    If you are going for an LG TV, it's OLED or nada.
    If you are thinking of getting this TV because of the apple tv 4k, eh don't. 4k alone is just about what Spankey stated.
    It's not really about the 4k, it's the HDR.
    In fact, Sony has 1080 TV sets with HDR now.

    How much money do you have? OLED is still pretty expensive compared to 4K HDR Sets. Especially when you go above 65". I will be getting a second 4K with HDR and would prefer the OLED (probably LG) but I also want it to be 70" or bigger. Of course maybe there will be Black Friday Sales (dreaming).

    OLED’s produce the picture by lighting up, QLED is just a different name for LED which has a light panel that turns on and passes through a color filter to produce the image. OLED’s can turn off individual pixels so you get a true black screen. Only downside is that static images can get stuck similar to plasma, BUT in general this can be fixed and is not permanent.

    QLED is not just another name for LED, it is a variation of LED technology which enables HDR.

    QLED means Quantum Dot LED, which is basically the same as Nano Crystal LED.

    A comparable technology is Wide Colour Phosphor LED.

    QLED is nothing like OLED, it’s a marketing term designed to confuse consumers. It’s is simply an LCD tv with LED lighting.

    Agreed, although it’s actually worse. There isn’t even such a thing as an LED tv, it’s LCD with backlighting provided by LEDs.

    Yes and now. The official technology is that indeed. However there are no commercial screens available. That is years away.

    The QLED you can buy today is nothing more than an ordinary LCD TV with backlighting provided by LEDs. It doesn’t even come close to OLED and it’s Samsung’s way of selling what are LCD TVs.

    That is not true. These technologies are actually for sale.

    A normal LED display uses blue LED coated with yellow phosphor for backlighting.

    A QLED uses blue LEDs, and a layer of red and green quantum dots that get excited to provide a whiter light source. Nano Crystal is similar.

    Wide Colour Phosphor LED uses a proprietary phosphor coating by Panasonic for the LEDs to also enable HDR.

    The point is that QLED isn’t going to come close to matching OLED in terms of contrast/black level. It’s still just a fancy LCD/LED TV. It’s also deceptive to average consumers since they will see QLED and think, wow Q is greater than O so it must be better!

    Well, "LED TV" is already marketspeak.

    Osram developed LEDs with a blue die, red phosphor, and green quantum dots. So that's another variation.

    TCL has some kind of "advanced LED phosphor" LCD TVs.

    Please do link to a Samsung QLED tv that you can buy today that is an actually QLED and not just an LCD branded as a QLED. I happily stand corrected and eat humble pie :)
    --- Post Merged, Sep 18, 2017 ---
    It may be market speak that doesn’t mean that it is anything else than an LCD display technology with LED backlighting or at best but still rare and often even more expensive than OLED a FALD to support the LCD technology.

    They are LED LCD TVs with quantum dots, not QD-LED TVs.

    Ok, so you do realise that quantum dot is simply yet another name for an LCD display technology TV.

    There is no such thing as a real QLED tv. Heck Samsung themselves don’t believe they can get the panels commefcially viable until 2019.

    As I said I happily stand corrected, but you and i both know it doesn’t exist done we :)

    OLED is a fundamentally different panel technology that provides a phenomenal and dramatic improvement to picture quality. It is an emissive display technology that is the natural next step from CRT and Plasma.

    QLED is a Samsung marketing term for LCD TVs meant to hide the fact that the TV is just an LED-backlit LCD panel with a slight iterative improvement.

    There are very good LCDs with very good picture quality like the Sony 940, but that is largely due to FALD and other technologies, and nothing to do with QLED.

    Of course all of this is only really relevant to home theater types who are picky about their picture quality. If you just want a decent TV, there are plenty of choices and LCD is much more affordable.

    There are no QLED TVs in the same sense that there are no LED TVs besides OLED.
    --- Post Merged, Sep 18, 2017 ---
    Except that Sony replaced quantum dots with phosphor, which accomplishes the same purpose.
