A Totally Untrue Word: "Oculus Quest 2 Supports 8K!"
Friends, as a result of my detailed investigations and trials, I have come to the conclusion that both 4K and especially the "8K video support" statement is a deception and is unrealistic. (We often see this statement in the promotions of video platforms that serve VR videos in 8K resolution.) I say this especially for Oculus quest 2, and this statement also applies to other VR glasses on the market that claim to be 8K.
First of all, the fact that a device runs an 8K video does not mean that that device supports 8K resolution, and it does not mean that it displays that video in 8K resolution. As a matter of fact, I'm telling you something very clear and precise: Take a 1080p movie video and pay attention to the details, and another 4K movie video and pay attention again. (Watch on a 4K TV.) Now take a 4K and an 8K VR video and watch it in Oculus Quest 2 and pay attention to the details again.
What I saw was this: The detail level of the video they call 4K VR video is not even at the level of a 1080p movie inside the device (let alone the 4K clarity)! More blurry! Maybe we're only watching a 720p clear image because it's a 4K VR video!
On the other hand, supposedly "Quest 2 supports 8K video!" Take a look at what they say: Between 8K VR video and 4K VR video, when you're watching inside your Oculus Quest, you can't really see anything noticeable between the two in terms of clarity and image quality! Because there is no such difference!
Already the resolution per eye is described as 1920 x 1832 for quest 2. But for some reason, I don't understand why, it is stated that it sums the resolution of both eyes and has a resolution close to 4K. I think this is completely unfounded. Why are you collecting the resolution of both eyes! What logic does this have! Totally a commercial scam! Nonsense! For one thing, this 1920 x 1832 resolution is more than 1080p and less than 2K, and when you look at it with both eyes, the resolution you see is not close to 4K, but as I said, it consists of an image quality that is even lower than 1080p!
Our eyes see and we can compare the difference! Although you try to fool us! As I said, the 8K video you watch on the oculus quest 2 device does not visually differ from the 4K VR video. Because this device does not have the feature to display 8K resolution! It doesn't even have a feature to show 4K resolution! A video that goes into it in 4K looks even lower quality than 1080p. Can't you see and compare?! Please be careful!
Just like this, the device marketed as 8K VR glasses on the market has nothing to do with 8K. They already say 4K per eye. I guess this means a level of clarity that does not even reach 4K inside the device.
Already AMD's Raja Koduri says that we need 16K at 240Hz for "true immersion" in VR. And the Oculus Rift maker says at least 8K resolution per eye, or even more, is required to achieve truly clear image quality.
Yes, Oculus Quest 2 is still the best quality and affordable device in terms of price-performance and image quality, and it offers you an impressive visual experience despite all these facts. A 4K VR video provides a very lifelike image and is extraordinarily amazing and beautiful to experience, but the statements that there is visual quality in this 8K or even 4K resolution within the device are completely untrue and untrue.

Thanks for sharing, I was thinking the same when viewing 4K videos on YouTube.. truly bad quality.
I think however when they say 4K they mean that the 4K is spread along the whole 360 degree canvas, which makes the viewing area less than 4K and why you see the bad quality at 4K videos.
However what is preplexing is whether an 8k video actually doesn’t differ from 4K. My experience by viewing 8k vs 4K videos on YouTube is that there is a difference.

I think Meta, and before that, Oculus have always been very clear by saying a resolution "per eye" and not adding the 2 together unlike 1 manufacturer I remember.
Also, to view videos in best quality you would need to play them on the device, not watch on youtube or any other streaming app.
Does an 8K video played on the device look better than a 4K video? I'm not sure. I know that videos look so much better than when I watched them on the DK1 and I hope and expect the Quest 3 and 4 looks even better than today's headsets.
I can happily watch films on the Quest 2 and think the quality is very good. It isn't 10/10 but for me it's an 8.

Glad I stumbled across this post while trying to figure out why 180 3D content on my Quest 2 is worse than my Original Quest! For example, a 3840x1920 60p H264 video is BUTTER smooth on my Quest 1. That same video is not as smooth on the Quest 2. On both headsets, I'm using the native VR Video player.
As a test, i loaded that same 3840x1920 60p but in H265 on the Quest2. The video was brighter and a little sharper but still not buttery smooth.
That same H265 video stuttered quiet a bit on my Quest 1 which is understandable because the Quest 1 doesn't fully support H265.
I've done a quite a bit of experimenting with different videos using different compressions (H264 and H265) and in ZERO cases did the Quest 2 have silky smooth 180 3D video playback. In EVERY case, the Quest 1 displayed silky smooth 180 3D video playback for files; even up to 4096 so long as it was H264.
Any thoughts on this? Thanks!

I agree with you about the 8K claims.
But I think you have got the 4K bit wrong. Each eyes portion of the screen is only half the width, so 1920 vertical lines of pixels is the exact same clarity of 4K.
Although, the clarity won’t look as good as watching a 4K TV, unless you have your eyes 1 inch away from the TV!
