4k Gaming? Is it Common?

[Blueprint]

Recently I have seen some videos with 4k resolution on Youtube. Also, earlier today I saw a montage from Battlefield 4 that was in 4k. Are these videos in ligitimate 4k? Or are they rendering out as 4k whereas the quality of the video isn't? Is it common for youtubers to play intensive games such as BF4 in 4k at a good framerate?  I'm really confused as to how people are hitting 4k resolutions (if it's true) as recordable and playable frame rates.

and this? - http://www.youtube.com/watch?v=_TXHzHLlGjM

Throw enough GPUs at that resolution and it'll play.

These are 1080p videos rendered out in 4k.

Do you know how does this affects the quality?

How it effects the quality? Of course its going to make it better.

It doesn't look like real 4k, then again I cant tell I'm not using a 4k monitor, when I went to the 1440p though it didn't look like 1440p.

It's 1080p rendered @4k...

Wouldn't upscaling a 1080p resolution video to 4k degrade the quality by a significant amount?

Well, YouTube supports 4K video now. So it could be full 4K the whole way through from recording to uploading. Though 4K gaming is still kind of uncommon, because you'd need to sell a kidney to buy a monitor.

we are talking prices in the thousands and thousands of dollars here, to answer the op, no it's not common even in the slightest, maybe a selected few crazy people out there have it but the rest 99,5% of people, no.

 

not only do you need a stupidly expensive monitor but you need the graphical power to run it aswell, as in sli/quad 780ti/r9 290x.

I think 4k gaming is still 5 or so years out. The mid range and low cant get anywhere close just yet

Hardware is still trailing behind.

No. It won't be anywhere near the quality of a 4k video rendered in 4k. But doing this gives it less compression and a higher bitrate when you upload it to youtube, as compared to uploading it as a 1920x1080 video.
