    There actually is such a thing as an 8K Association which is based on the big players in the industry. The group now has passed "performance specifications" requirements for 8K television...

    Would have been nice to use it as an opportunity to clean up the spec's. Although it specified HDMI 2.1 it doesn't specifically specify you need to support all the features of it. (from what I gather) I would have liked eARC for example to be a mandatory requirement.

    Considering it's just for TVs, I reckon there's no special need to enforce everything. I guess only the bare minimum for TV use would be more logical. After all, all manufacturers try to save where they can. For example variable refresh rate is a part of HDMI 2.1, but it's not necessary for a TV, unless the TV is used with a gaming device.

    7,680?

    Someone can't add up, that figure needs to be 1,024 multiplied by 8, which gives a number of 8,192...they are missing 512 from somewhere.

    (for those of you who don't know, the "K" equates to 1,024, this means nK, and you transpose "n" with the multiple)

    Muppets.

    How about a minimum size standard, ie, 65", to prevent the industry from bilking clueless consumers who may think that 8k is twice as visually stunning as 4k from 10-12' away.

    4K/8K is the absolute maximum of panel capabilities. The proper resolution is relevant only to "HD" world. This is the usable resolution.

    Only if you select input as Hdmi full spec 8k smpte you will get 8192×4320. But, the recommended resolution though for all apps is UHD 8K 7680*4320. The same goes for full spec hdmi 4k smpte vs 4k UHD. Many apps are out of bounds or just wrongly displayed with 4096*2160, so, the best is 3840*2160, because of HD multiplication.

    Aspect Ratio...16:9 4k monitors use 3840 x 2160 while DCI (aprox 17:9)uses 4096 x 2160, same thing applies to 8k.

    So it's actually 7.5K, not 8K. xD

    1.78:1 is a horrible ratio and is no excuse for any company/org to mislead consumer into thinking they have got an 8K device when they haven't...their get-out-of-card card is the inclusion of the "UHD" label, as if that excuses the lack of precision.

    You guys know my feelings on this, and you know I'm immovable on it. I'm right and they are wrong.

    Still waiting for the rapid growth of 4K content.

    Another not very useful association proposing another messy specification.
    Sloppy from the start, missing 50p. Hope they just forgot it in the news summary but knowing the players....

    For those of us who don't know? Since when were display widths ever intentionally measured in bytes? 1080p is 2K. Last time I checked, 1920 is not the same number as 2048. 4K is 3840 pixels wide (1920x2), which is clearly less than 4096. 8K is double the width and double the height of 4K. Notice a pattern here? They're just rounding up to the nearest thousand.
    So far, the only resolutions that follow a multiple of 1024 are 2.5K (which everyone refers to as 1440p) and 5K. Part of me wonders if that's just coincidence.
    However... I do agree that it's a bit of a stretch for them to round up 7680 as 8000 (or 8192 for that matter).

    EDIT:
    BTW, the most common form factors are measured in 16:9, 16:10, 4:3, 4:5, and 2:3. Of all existing resolutions, none of them are an exponent of 2 for both the width and height. So, if you insist an 8K resolution is supposed to be 8192 pixels wide, what about the height? If you conform to either 16:9 or 16:10, you're not going to get a clean squared number.
    What a reckless level of arrogance.

    Jeez dude.. who is going to be complaining about not enough pixels @ 7680?

    Personally i'd rather have something able to scale 1080p content easily and almost perfectly than having a perfect multiple of 1024. This said maybe a multiple of 42 would be better. Dunno. Hard question to answer.

    Still waiting for most content to be available in anything 1080p+, and for the "1080p" content available not to be at so low bit rates that it's literally lower quality than medium bit rate 720p.

    Edit: Missed a word.

    seeing as 1080p isnt even standard yet we will be waiting long time hell we still have 480i\p transmissions. 1080p on dish isnt even 720p quality imo forget about they fact there base transmissions isnt even progressive. all other cable company and satellites company are quilt of this same habit too, Netlfix and other streaming services are closer to actual 1080p quality. forget about 4k or 8k being thing anytime soon. Fios has better PQ then Dish dont know about direct tv as i not seen them in decade and most cable company imo have better pq then Dish too, Dish imo has the best receiver in that hopper 3 and 16 tuners to bad there transmissions is low quality.

    thought I would not mind 50" 8k TV to replace the 55" 4k I have. I dont care what anyone says to me 4k look better to me on 50" vs 65" 8k will be no different. I dont have never bought in to this " screen size" must be certain size for certain resolutions to be meaning full or seen. those those people I say "get" new eyes

    If "4k look better to me on 50" vs 65", then more likely it is due to better TV quality than due to the screen size. If you think "8k will be no different", then you have thrown the law of diminishing returns out the window and probably think 16k and 32k will similarly look better on 50" vs 65" as well. :rolleyes:
