Heck, one of the selling points used to be (and may still be?) was the better LDC manufacturers warrantied their panels for no dead pixels out of the box!

It helps that the pixels are getting smaller and smaller though, not that it means they don't die but it makes them much harder to spot unless there's a cluster of them. I've got a few dead ones on the ZD9 but from 7ft away they're imperceptible.

That's a fair point, Geoff. I guess I was thinking that, on the flip side, with them being both smaller and greater in number, the "risk" of a bad "interconnect" (for lack of knowing the proper term) between sub-pixels would be higher, thus potentially resulting in enough bad pixels for the viewer to notice. But, hell, we're manufacturing CPUs, GPUs, and SoCs at 7nm now, which I assume is MUCH more narrow than the circuitry on a 4K or 8K LCD panel, lol.

The world's first 8K television (85") was unveiled by Sharp at the Consumer Electronics Show (CES) in 2012.

Just how fast is that internet around the states for higher speed streaming. Goes with the 8K streaming that they were trying to reduce from 80Mbps down to 60 Mbps. Of course no one thinks about you need so much speed faster then that for the stream to be without interference or buffering issues, not to mention multiple stream usage in a family residence.

The 10 Fastest and Slowest States for Internet



States with the fastest average internet speeds:
Maryland – 84.1 Mbps
Delaware – 80.9 Mbps
New Jersey – 76.3 Mbps
D.C. – 75.2 Mbps
Virginia – 74.5 Mbps
Rhode Island – 74.5 Mbps
Massachusetts – 73.6 Mbps
Colorado – 70.9 Mbps
Washington – 67.3 Mbps
California – 67.2 Mbps

States with the slowest average internet speeds:
Alaska – 20.6 Mbps
Montana – 30.1 Mbps
Maine – 30.8 Mbps
Idaho – 30.9 Mbps
Wyoming – 33.3 Mbps
South Dakota – 33.3 Mbps
Iowa – 35.8 Mbps
Arkansas – 37.3 Mbps
Mississippi – 37.9 Mbps
Hawaii – 38.1 Mbps

makes me grateful of my 600 mbps (sustained) internet speed.

I live in a very rural area of TN (county has a population of maybe 8,000). I couldn't believe it when, probably, just over 5 years ago, on my way home from work, I see our local telephone cooperative with contractors out trenching what looked like spools of fiber. This same telephone coop provided Internet to about half of the branch offices at the bank I work for, so I was on a first-name basis with the head of the Internet department. I e-mailed him the next day and said, "Joe...did I see Loftis contractors trenching freaking FIBER in my very, very rural part of the woods?!" The reply was "yes", which blew my mind. A few weeks later, I have a 50 Mbit ONT (optical network terminal) on the outside of my house. They offer full gig for bot business and residential. The only "bad" thing is that, being a smaller coop, their prices are somewhat higher than someone larger like EPB. But given the fact that just prior to their fiber build out, the fastest Internet I could get, given my distance from the DSLAM, was 3 Mbit DSL...I was overjoyed to say the least. It's my pleasure to do business with them to this day.

See if you can get a 4K and 8K version of Stacey’s clip - https://www.techhive.com/article/352...ifference.html

And run ‘em simultaneously into the side by side 4K and 8K tv.

Can't help but wonder if your interested in correlated observations concerning this paragraph from your link. Possibly to suggest that certain examples are more decernable than other content.

Similar to the CM example of looking at the fine print of a newspaper then a image that is harder to make out fine detail differences.

Stacey Spears’ nature footage had a different distribution of scores than the other clips, with more responses rating the 8K version better than the 4K version.

I would love to get his 8K footage. Where can I download or ask him?

Stacey's been very active, regularly, with Q&A on AVS for the past couple months and I think when you quote someone there, the quoted person gets a heads-up in his email box….so it’s quite efficient communication that the administrators over there have set up for membership.

If it can be made to work, there are lots of things one could do with Stacey’s video, which is certainly more pristine than anything you’ll get in the near future vis-à-vis streaming or broadcast and could serve as one benchmark source for Robert’s evaluation(s). Since the acquisition of his footage was 8K, I would also be interested in the winning 8K tv being fed the native 8K footage,

along with Stacey or Robert’s people also converting that clip to 4K (PERIOD, not upscaling back up to 8K like Zink did) and feeding said 4K into his winning 8K tv to see how well the TV’s upscaling performs, something the WB et al. study didn’t investigate…….the significance being, answering - as long as future material is shot in 8K and can only be delivered in 4K, is it really a big deal not to have 8K acquisition and 8K delivery content if one owns the best upscaling 8K tv?

10-YEAR-OLD 2K CINE CAMERA GOES UP AGAINST 8K SMARTPHONE CAMERA IN THIS SIDE-BY-SIDE COMPARISON

[sapiendut]

Not surprising at all. Even my decade-old 8mp dSLR looks better than my iPhone 11 Pro gabijillion MP camera.

[JohnAV]

A smart phones sensor and miniscule fixed optical lenses renders poorer quality images compared to good camera of the same resolution.

[Lee A Stewart]

You can have a million K camera. What you need are top notch lenses which no cell phone is going to have. Not a real comparison. I bet a professional NTSC broadcast camera would beat that cell phone.

The only thing 8K will do for cell phones is give people the ability to crop their photos and still maintain some semblance of a decent image.

Yes the first YouTube is from four years ago, and the two next ones are from a year ago. No need to watch, it's only for hardcore cinema enthusiasts.
For inspiration mode only (during a pandemic to spend time interested in the art of moving pictures).

[sapiendut]

It’s annoying when people look at my photos and say “that looks good, how many MP is the camera?” This is while only looking at my pic on a 30”x20” print. I usually tell them “you don’t go to a girl saying you look pretty, how thick of a make up are you wearing”

SMH. LOL.

Actually it will do two other things, reduce battery life, and use up all the storage. Its not like you can record a very long 8K video on a phone.

None of the phones can even come close to what you can do with say a compact Sony RX100 series camera can do in 4K.

Just bring us those 8K cameras, still no date for the 8K Sharp yet.
