Just tested the linked 8k youtube video on my Windows desktop and M1 Mac mini
Both ran 8k60 (which is quite a bit more demanding than 8k30, which itself is close to 4k60) without dropped frames
Both were on Gigabit ethernet.
The desktop RTX 2070 super was pegged at 80-85% and internet usage was around 90Mb/s
Tried on my 2018 iPad pro too, but it does not allow more than 4k60, which runs with 0 dropped frames
With a local file I don't know of a precise way to check dropped frames

You probably won't find many here if only because you can't hook up an 8k60hz display to a macOS/tvOS based device without jumping over an excruciating amount of hurdles. Take a look at this thread to get an idea of the pain someone went through to get their Samsung QN900 working on a Mac Pro. The nearest solution for 8K on Apple Silicon is the UP3218K either running at 30hz or 60hz tiled/PBP (meaning it effectively appears as two screens to your computer), and I'm still waiting for confirmation that isn't broken on Apple Silicon.

Meanwhile, you've been able to run 8k60 on Windows going on 5 years now...
I didn’t mean just for a Mac. Who here has an 8K monitor or TV period? Windows, Linux, DOS or whatever. I’ve never seen anyone in real life with one so I was seeing if anyone here had one.

I have a feeling that the answer is no one here has one but I could be wrong.

Think about it, if you do many online meetings or chats you only want a 1080p Camera because whom wants to see the last time you shaved! Besides when girl on Zoom uses her 4K videos guys can see her Woman’s mustache?
1. You are not funny. Not in the slightest.
2. Your use cases are not others use cases. I don't think anyone here is talking about streaming 8k over zoom. They're talking about 8k content consumption.

Agreed, but I think we are very near to hitting the inflection point where there are enough options, enough demand, and enough economies of scale that we'll soon start to see them becoming much more common.

If you had read my posts in this thread you would have an answer of at least one.

Or you could just answer my question? There’s 105 posts in this thread. I’m sure it’s possible I could read every single one of them but I’d still miss something.

So you have an 8K monitor?

I don’t think we’re anywhere near that point. There will be a point where 8K monitors become the higher end standard though. I mean the price of a quality 5K monitor is expensive enough for most people.

You don't need an 8K capable display to benefit from 8K streaming quality. It's common for people to play 8K stream on a 4K display to offset loss of detail from streaming compression.

Look at 'stats for nerds' in YouTube to see if it's VP9 SD or AV1 HDR high or highest bit rate. I'm guessing it's probably VP9 which is a lot lighter on resources than AV1.

Seriously this doesn’t sound like a real thing. I really have never heard of anyone doing this. I have a 1080P monitor and YouTube doesn’t look any better at 4K. I’ll try watching 8K on it to see if it makes a difference.

They're all going to be streamed at 640x360 anyway.

What size display? I'm on 48" so it's noticeable. Smaller may be less noticeable.

24” for my gaming PC. I would never go larger with 1080P. I really hope your 48” is 4K because if it’s 1080P you don’t have pixels, you have dots lol. I had a 32” 1080P and it was terrible.

I think many people here don't understand that the people who are chasing 8K generally *are not* gamers. They're either consuming content on exceptionally large screens, or creating content a la developers, digital media, etc. Trying to game on 8k is still 5-10 years away, especially when considering many gamers nowadays want 120hz or more, so there's little reason for gamers to bother with 8k displays.

So, in Chrome these new Macs have 4K and sometimes 8K available on youtube videos.

In a video I heard a guy say that if the machine is detected to be a MBA M1, the 8K option is not offered, whereas if it is a MBP M1 it is offered. Is that true? What about the Mac Mini M1?

Now, even when 8K is offered, can it actually run smoothly? I’ve seen it stutter in a video but it was not clear if it was a buffering problem.

What are the experiences of the owners here with 8K youtube?

(not that it’s a deal breaker, just a curiosity)

I have seen 8K offered up as an option on my M1 Mini. It takes all of the CPU power though, and I bet a good portion of the GPU as well.

That is because the streaming protocol is not fully up to specs yet! Sure Google is working with own but the mp.4-5 protocol was just updated less that 2 years ago! I’m with other, 8k is looking to far ahead and we see great monitors to least 2028 that show 8K!

What does licensed MPEG-4/5 codecs have to do with YouTube which only uses license free VP9 and AV1 codecs? High CPU utilization is a result of lack of hardware decode and CPU has to software decode which is very taxing especially for AV1.

8K display is already here.

This seems like a decent explanation. Old video, but I never forgot it.

Can I see the difference? Sometimes, it depends on the actual content.

Chroma subsampling is real, but trying to work around it by playing a super high res video and downsampling it seems unlikely to do much other than waste your bandwidth. There's a simple and good reason why it's a standard practice in broadcast video and lots of online video: our eyes have lots more rods (luminance sensors) than cones (color sensors), meaning we see luminance resolution far better than we see color resolution.

As I understand it, that's why videos get transformed into the Y'CbCr color space. In RGB, chroma and luma resolution are entangled with each other, but in Y'CbCr they aren't, which is how they can reduce just color resolution while leaving luminance resolution intact.

I never actually tried playing a video until just before writing that reply, I see no benefit to it when I have a 4K monitor and that plays super easily.

I’m just curious but does anyone in this thread have an 8K monitor or television? If so how much did it cost you? I don’t know anyone personally with such a device but it’s like all technology it comes out slowly
8K televisions aren’t crazy expensive anymore. Currently in the US, the 65” TCL R648 is $2000. The 65” QNED99 and QN800A are both $2500.

In the UK, you might be able to find the 55NANO95 (2020 model I think?) for £1200. I wish a 55” 8K model were offered in the US!

The M1 Max 16 only supports up to 6K so why would you try to output 8K?
Presumably you get better sharpness downscaling 8K to 6K than upscaling 4K to 6K? Or you have multiple 4K monitors?

Also because a bunch of us want 8K output, even if it’s not yet supported.

My current desktop has 3 4k monitors, a 5k iMac and a 2k iMac. 4k video off of YouTube taxes my bandwidth as it is. I usually watch in 1080p or lower.
