Hi all .
Please tell me, can I watch 4K and 8K video on libre hardware? Or the maximum is 1920x1200 60hz
I will be grateful for your answers.
Why don't you leave us a link for a 4k or 8k video you are trying to watch and we can try it out and tell you our hardware and if we were successful. I don't know where to find a 4k or 8k video to test it on.
The question lacks some key details. Here's what we should consider:
* What what codec? Different codecs have varying processing demands. Some are "lightweight" and require less power, while others are more complex and require more processing power ("heavyweight").
* With what hardware? The capabilities of the device will affect how well it handles different codecs. A powerful computer can handle heavyweight codecs more easily than a less powerful device.
* At what display resolution? There's a distinction between the file's resolution (which may be 4K or 8K) and your display's resolution, which may be different. Even if the file is 4K or 8K, but your display is 1080p, you'll only see 1080p. However, your device still needs to decode the entire file regardless of what's displayed so that question of being able to play it still applies but the question of decoding 4K/8K and displaying 4K/8K are different.
In short, more information is needed to give a specific answer.
Here's an example if anyone wants to try a 4K video.
Using this command you can see all available resolutions and codecs. Notice the letter F is capitalized. That will be important later:
yt-dlp -F 313+251 https://www.youtube.com/watch?v=tXlAdjCoGDQ
If you'll notice, the 4k video is only available using the VP9 codec. (The terms 4K and 2160p both describe the resolution of 3840×2160 pixels.)
So download that, plus put in the Opus audio codec. Notice that the letter F, previously capitalized to get the list of available codecs, is now lowercase to actually say which to use:
yt-dlp -f 313+251 https://www.youtube.com/watch?v=tXlAdjCoGDQ
I can say that my Asus KGPE-D16 with NVIDIA Corporation GK110 [GeForce GTX 780 Ti 6GB] plays it just fine although my displays are only 1920x1080, so it's only decoding that file not displaying that many pixels but still, it shows that it can decode the file in real-time which is an important first step in being able to play it. I wonder if I should try getting some 4K monitors to see what happens...
As a disclaimer, I live in Seattle and have also gone to both of these Re-PC locations to also geek out over the stuff.
If someone wishes to try with a non-youtube video, here is Big Buck Bunny in 4k at 60fps:

My poor T400 cannot obviously play it.
I still think for most trivial watching 720/1080 ought to be enough, but who am I to judge. Go crazy on those higher resolutions mates! ;)
An Intel integrated videcard on a Sandybridge[1] can't either.
It looses ~50% of frames, so maybe 4K @30fps could work, maybe not even that.
Too much for my old faithful.
Cheers!

It plays for me.
Here's what I get while running that BigBuckBunny movie via VLC on the new NovaCustom laptop with Alder Lake Intel cpu with Intel Xe integrated graphics. It looks very good and clear and smooth video. Not many dropped frames. It appears that VLC is reporting 3840x2160 at 60fps, which an internet search tells me is 4k video. If I'm reading it wrong, let me know.
The fan is running at about medium speed while the video is playing, so it's a bit of a stress. I'm assuming the graphics are running via llvmpipe, so the CPU is probably doing most/all of the work. If I could get the integrated graphics to take over it would probably run without much fan noise.
Big Buck Bunny at 4K@60fps plays just fine for me with the integrated graphics on my Intel Skylake NUC. Like jxself, however, I only have a 1920x1080 monitor. I have used a 4K monitor in the past with this machine (supplied by a previous employer) and can verify that it is capable of rendering at 4K (with one caveat - I don't think I ever tried playing a 4K video on the 4K monitor).
On my older Haswell NUC, the Big Buck Bunny video also plays at 4K (connected to a 4K TV), however the integrated graphics on that machine can only render 4K@30fps. Checking the VLC statistics reveals that there are quite a few dropped frames, so you probably want something more powerful than this.

I was able to play it on my UHD 770 with my i5-12600K without any lag at all. On my T400 it was very laggy and my T400 has a Q9300 in it rather than a dual core.
All I can say was it was a very gorgeous video so I can see why people want higher resolutions.

The carbon footprint increases with the resolution. Using a lower resolution is more ecological. That said, it does not make much difference compared to taking more public transportation (or a bike) or to eating less meat.
Nobody can see the difference between 4k and 8k, unless she is glued to her screen: 8k TVs are a scam! Maybe a difference can be perceived in a cinema (I do not know if that was tested).
I will add something even worse in my opinion: Instagram Livestreams.
I sometimes watch a livestream from some people who I enjoy listening to their speeches and stuff (proxigram is very helpful after bibliogram went dead). I usually download them to watch on my offline machines.
It amazes me that for something that most people will watch in a hand sizes screen, usually it's just the speaker's faces looking at the camera while they speak (some do have presentations, but not the majority), and Instagram forces 720p! An hour of a simple "talking portrait" will take ~500MBs!
When someone uploads their livestreams to youtube and I get them through Invidious, the picture in 360p looks just as good (yes, smaller resolution, but it's not bad by any standards) and the size is ~150MBs.
So yeah.... these companies actually help pushing the whole "higher resolution is always better" thing. Even when it's not important at all.

In Invidious, click on the icon representing a headset (at the right of the title) and you will only download the audio.
Good sharing!
I actually know and do that already, but I was not thinking of sharing that tip.
An hour of streaming (which in Instagram is a 720p video ~500MBs), if you choose an audio with smaller bitrate, you get about 20MBs file size. And you get the same information :)
Youtube has many issues in the way it disrespects its users, but it does offer a wide variety unlike Instagram.
That GPU doesn't exist. Instead, you can find the GTX 780 non-Ti with 6 GB of VRAM or the GTX 780 Ti, which has 3 GB of VRAM. The only option similar to a GTX 780 Ti with 6 GB of VRAM would be the Titan Black. NVIDIA had plans to release a GTX 780 Ti with 6 GB of VRAM, but they ultimately decided against it to avoid cannibalizing sales of the Titan Black.

It is rumored that only two specimens of that graphics card have ever been made. One is in Seattle, and the other one is in the castle of Arrrrgh.
So you must be in the castle of Arrrrgh, because Seattle is an imaginary place.
I see. It doesn't exist as such since it never hit the market, as you can see by searching on any search engine, for example, in this link: https://www.techpowerup.com/gpu-specs/geforce-gtx-780-ti-6-gb.c3302
Furthermore, in that same link, you can see that the processor of the supposed 780 Ti 6 GB is the G110B, while the one you have is the G110, without the B. Taking this into account, the driver may be displaying an internal name rather than how it was marketed. Considering that it indicates it's the G110, I believe you must have the GTX Titan: https://www.techpowerup.com/gpu-specs/geforce-gtx-titan.c1996 (you don't have the Titan Black because this latter one has the G110B processor).
One way to verify this would be to check the GPU and the labeling on the casing: does it say 780 Ti or Titan?
I wonder, do I need to disclaim as well? Aieesh! I missed Fry's.
Guys, thank you very much for your helpful answers.
In my case, I'm looking for a monitor for ASUS KGPE-D16 and I was thinking about a higher quality monitor.
Jason, thank you for the helpful answer regarding the video card, which I am planning to order, I am gradually moving towards my goal...
PublicLewdness Hello.Please tell me, did you assemble your laptop yourself and install a 4-core processor or did you buy it here https://thonkpeasant.xyz/guides/other/quad.html?

I purchased mine from ThonkPeasant. Was a great experience. Shipping was fast, although i'm in Canada as are they so that isn't shocking. The laptop came looking like it was brand new. It was spotless. price was fair as well in my opinion.
Magic Banana Hello . I agree with your opinion, I just wanted to understand if this option is possible.
