Which connector are they using for 8K bandwidth?
8K TV any one?

HDMI 2.0b. Though for the most part 8K is only from the USB right now.
Can only do 4:2:0 30hz 8k over HDMI 2.0, 2.1 is needed really.
I can't help but think this is an especially easily purchase, by the time 8k content exists and devices work properly it won't be useful - just like the first 4k TVs with HDMI1.4 or no HDCP 2.2.
I would have thought a 77" OLED at half the price would be considerably better, ofcourse the brightness is lower but the other PQ improvements OLED brings more than makes up for that. Who the hell needs 4000 nits, my XE9305 supposedly hits ~1300 and it's WAY to bright.

Seems a bit of a pointless buy then :/ Can't even do 8K gaming on it - one of the only viable sources
You have to remember, even if this can't properly support 8K yet it might do in the future, due to the nature of the One-Connect box. More importantly, it's the best 4K LCD out there and considering the price it's not much more expensive than the purely 4K alternatives. So 8K is a nice cherry on top, not the whole cake.
Well, you can, just not quite natively (DSR, render scale, etc.) Also, keep in mind that pixel density improvements are still a huge upgrade even if you run it at 4K, especially for the sizes this TV comes at.
Pixel density improvements are always good:
1080p content looks better on a 2160p screen;
1080p content will look better on a 4320p screen;
2160p content will look better on a 4320p screen.
Also, 4K is just 8MP. With an 8K screen you will be able to open 33MP photos on full screen
Samsung have actually confirmed to all the initial reviewers and also on there official website at the bottom that an upgraded HDMI 2.1 connect box will be made available next year once its ready. Apparently it wasn't ready yet when this TV was made but they are making a 2.1 connect box available next year. The only thing unsure yet is if it will be a free upgrade or a paid upgrade.
This is what it says on the official website.
"Complimentary HDMI 8K 60A (uncompressed) upgrade included by Samsung"
And from the Trusted reviews review of this model
"Samsung is, however, going to start shipping Q900R TVs with new One Connect boxes in the new year that carry a single HDMI 2.1 port. These boxes will also apparently be available as upgrades to people who buy Q900Rs now"
From my 4 days with this TV somethings I have noticed is the following.
Forza looks phenominal on this TV. Upscaled to 8K you can see the difference in clarity in sharpness and the 4000 nits of brightness really shines (pun intended) with things like the reflection of the sun on the car bodywork. I believe all HDR games are graded at 4000 nits apart from Gran Turismo which is 10000 so being able to see the content like it was graded is spectacular.
I watched Infinity war the other night and compared to my 4K Q9FN there was an upgrade in clarity and detail. No aliasing to be seen and certain scenes had the look of looking through a windows rather than a TV.
1080p content looks much better also and looks closer to 4K than 1080p on the 75 inch model. As someone who owned both the 4K Q9FN and now this 8K you can certainly see the difference with lower quality content and as a huge gamer 4000nits plus Variable refresh rate is such a great combonation.

Vicariously living through you right now Matson, thanks for all the updates (been following on avs). Any chance you could look at some youtube gaming 8K and let us know how it looks to you? I'm talking specifically about this, and videos from this guy's channel, compared to on a 4K TV.
why do you think that ?
clearly it will shine with 8k content, games, windows desktop
otherwise, it is the upscaling algorithms that will play a big role in its success, you have to be able to cubic interpolate, or something, based on neighborhood of pixels, and decide how one pixel in original material will be mapped to 4,9,.. ? higher density pixels
yes it will be harder to discern the pixels up close to screen ... but - you have to decide how to fill them
(you are not getting the same up-density improvement in light output , too .... nits = light/area)
Iv actually posted more pics and impressions on AVF rather than AVS as im from the UK. It currently doesn't have the codec for youtube 8K. I guess with it being so new and being the first proper consumer 8K tv. Id imagine that will come once they add HDMI 2.1 next year. That Star wars video looks incredible though. Its hard to compare without watching it side by side with a 4K set but upscaled to 8K the clarity and details looks stunning. Makes me wish I had the PC to run it at that
. The only Native 8K content iv currently seem is the Shop Mode demo real. It looks a step above its just a shame its going to be most likely years and years before were able to watch movies in that quality. I would guess Netflix will bring out the first 8K streamable programs and we most likely wont even get 8K discs.Between the pixels you have blank spaces - the smaller these blank spaces are, the better the image quality. Because these blank spaces are black, at lower resolutions you get the colour from the pixel plus that black surrounding.
If you had a PC you could hook it up and try, for the youtube vid I mean? Yeah, AVF, woops, get them confused. Or perhaps download it from youtube and watch on USB, depending on what formats work, but that might be too much work.
the blanks/space between the pixels don't necessarily decrease with higher pixel density, just the pixel size itself, as the gaps may already be minimum for the photo-etching process, to maximise image quality. would need to also turn up the backlight to preserve nits.
(a 75" 8K is like 4 40"4k's adjacent too)
More likely, since 4k screens of say 40" and 65" have the same number of nits, the pixel size versus gaps remain in the same ratio, and image quality is the same.
I haven't looked through a microscope at a smartphone screen with, let's say, 500-800 pixels per inch density, but I bet there are no gaps at all.
Also, am not quite sure how you got the brightness levels thing in connection with the pixel density. Many screens or most screens are coming with edgelit.

.. there always has to be a 'gap' - yes ? - you need electrical isolation of the pixel areas - look up lcd fabrication.
but the gaps will be as small as manufacturing tolerances and the design permits, you want as much light transmission as possible, you could have a more expensive manufacturing process at higher dpi's, but the gap would need to shrink by 2, say, if the pixel density doubled, to maintain the pixel area or light would have decreased.
[see earlier oled posts here - lg increased the pixel size on the c8 vs b8, just at 4k (ie dpi constant), for reliability, nits went up a bit too,
they had probably improved manufacturing tolerances that faciliated this]

transmissive lcd's (vs emissive oled) have a backlight so if gaps remain constant as pixel size falls, you need to increase backlight intensity to retain nits, thats's the brightness connection - it's all related.

I find the most impressive aspect of 4K on my OLED is the HDR element. Will 8K bring any improvements to that? An even wider colour palette!?

Yes, in fact the higher PPI will noticeably improve the overall presentation wrt colours (in terms of banding etc.).
had not seen these flatpanel comments about samsung 8K upscaling before - so AI's not a panacea -
I wonder if madvr could do better, or there is not enough processor/cpu power, since problems the same as upscaling 1080p->4k ?

I think the tech is just not there yet. If you look at DLSS, they're trying to do much the same, but the results are similar - smudgy image with loss of detail. I don't see Samsung achieving anything better than Nvidia any time soon. Heck, even today you can access a similar feature with the Sony TVs, Reality Creation. Sometimes it works really well (e.g. had the best success with it in GTA V, run the game at 1080p/1440p then up RC to 30-50 (depending on model) and it looks close enough to 4K mild AA), other times not so much.
