I saw a add on face book claming netflix is going to start streaming in 4k. half the people didnt know what 4k was and i explained it as 4 times 1080p or ultra hd. is that correct? I know i over simplified but these people are not tech savvy. and on a nother note rotflmao how compressed will it have to be and how much banwith would you need? and with how compressed it would have to be in my mind anyway why not just stick to 1080 or 720 it would look about the same quality would it not (because of the compression) ?

There's too many names. Just tell them it's better and they'll like it.

The only 4k show I can think of is House of Cards. I think in the next couple years bandwidth will really open up and it'll be easily streamed.

Yes, it is 4x 1080p.

What I don't get is how 3840 x 2160 is 4x the res of 1080p? :/

Still learning how to play Dota 2 :)

If you were to split the monitor into quarters, there would be 1920x1080 pixels in each quarter.

I like the color scheme of Noctua fans. Deal with it. Forget about the bad memories of the past.

Use this to help picture it. Keep in mind they all have same pixel sizes.

your doubling the perimeter therefore the area is four times or something like that, basically you could take 1920x1080 and put it in a 4k screen four times, so if you cut a 4k screen into quarters rd h quarter would be 1920 by 1080

If you put two 1920x1080 monitors next to each other, you get 3840x1080.  If you put two more on top, you get 3840x2160.  So, 4x as much.

 

Or you can think of it mathematically:

3840 x 2160

= 2 x 1920 x 2 x 1080

= 2 x 2 x 1920 x 1080

= 4 x 1920 x 1080

 

Or alternatively, just multiply the originals out and you can see: 3840x2160 = 8,294,400 and 1920x1080 = 2,073,600

 

But I think a visual is easiest

Yeah I get you, its just a bit hard to figure it out using basic math

Yea, I'm sure it's four times the resolution, Plus, YouTube has now got options to stream in 4k. I've seen this on like two videos though.

The problem with 4k is everyone uses that name not 2160p which is a better name when comparing 1080p and 1440p that don't use the horizontal size at all, just the vertical. It tries to make it sound like its a lot better than it is. Its realistically more like 2k than 4k in the terminology so far used, 4k is the marketing name not the technical one.

#k is counting how many horizontal pixels that a monitor has. Depending on who you are, you might say 2.5K when you're refering to 2560x1440 (about 2500 pixels horizontally).

 

4K has close to 4000 pixels horizontally, so that's why they call it 4K.

When was the last time you heard someone use 1920 and 2560 as the resolutions instead of 1080p and 1440p? Just doesn't happen, the vertical height of the monitor in pixels has become the defacto differentiator since HD was released. Before HD we had a lot more variety in resolutions, now its mostly 16:9 monitors at a few key resolutions and not a lot else. No one uses horizontal, it is just a marketing trick to make it sound better than the 2160p that it really is.
