What really is 4k

[Clovis]

When someone says 1080p I think 1080 lines by 1920 lines with 1 pixel in each box that is made witht the crossing lines on a screen. When someone says 4k i think 3840 lines by 2160 lines with 1 pixel per box just smaller boxes/pixels to fit the same space on a monitor as 1080p. Is that how it is? Or is 4k 1080 x 1920 lines but instead of 1 pixel per box, its 2 or 3 or 4 or whatever?

1080p is 1920x1080 so there are 2,000,000 pixels (1920x1080 ~ 2,000,000)
1440p is 2560x1440 so there are 3,600,000 pixels
4k is 3840x2160 so there are 8,000,000 - 4 TIMES as many as 1080p.

Also you do know a pixel can be different sizes, there isnt a fixed size when it comes to pixels.

For example you can get a 55 inch TV which is 4k which has a pixel density of 80.11 pixels per square inch, or you can get a Sony Z5 Premium (5.5 inch 4k display) which has a pixel density of around 750-800 pixels an inch. All screens have different sized pixels thats how you can get 4k 27 inch monitors and 1080p 27 inch monitors.

So basically 4k is 3840x2160 and you can get different sized pixels depending on the screen size so all 8 million pixels can fit inside. Its not a case of 1920x1080 with 4 pixels instead of 1 per 'box' as you call them.

4K Resolution is 4096x2160

UltraHD 4K is 3840x2160 (to match off the aspect ratio, similar to 1080p). This is what PC monitors will use, there's no real 4K monitor for gaming upon due to aspect ratio.

The real name is actually "UHD" (Ultra High Definition).
Similar to "QHD" (Quad High Definition) which was 1440p and "FullHD" which was 1080p.

4K is just a marketing glimmick and actually makes no sense.

It's all about the distance you sit away from your screen - don't fall for it.

That's where "retina" comes into play...

Most people using a PC, will sit around 3 feet distance from the monitor.

Retina display - is when the human eye can't count between pixels
(calculated by a viewing distance of 3 feet <> monitor size <> resolution)

1080p resolution - 19 to 24 inch monitor (max 27 inches)
1440p resolution - 27 to 32 inch monitor (max 36 inches)
UltraHD 4K resolution - at least 32 inches

So honestly, I wouldn't bother with UltraHD 4K unless on a 36 inch or larger monitor.

Pixels per inch (PPI) - aka Pixel Density, the human eye can make out to 300PPI, then doesn't discern with granular detail higher than that. Apple loves being Retina (using that word a lot), they use a 326 PPI display ever since their iPhone 4. As the screen gets larger on next generations, they keep the pixel density the same. There's no point going over it, on smaller screens.

well i have a 21:9 2560x1080 34 inch monitor and i cant see any pixels on my screen and its about 2-3 feet away from me. Then again my monitor is curved so i dont know if that makes a difference

Well yea and no.

People claim certain games benefit from the increased number of pixels and the higher refresh rate of monitors.

Most notably CS:GO. Does it really work? IDK personally. I just have a 1080 display that im about a foot away from all the time.

But i think the main selling point of the higher resolutions was for bigger displays that you could sit further away from.

Somebody told me this before and i can't remember who. Anyway 1080 looks good at a foot away, but 4k looks the same at 6 feet away on a bigger screen for PCs.

Like i said, IDK for sure, i only have a 1080p monitor. My phone is 1440p, but 577 PPI is kinda dumb on a 5.1" display. (Galaxy S7)

Pixels are all same size always ..., but in bigger display they are far apart from each other.....

2560x1080 is 1080p (vertical) resolution ultra-widescreen. The 34 inches is going mostly length wise (The screen gets measured diagonally), hense it's still retina (just). It's PPI density would be the same as a 27 inch 1080p resolution standard monitor, which is the max.

That's why there's ultra-wide available. It's similar to getting 2 monitors and placing them side-by-side, it's not actually stretching each pixel out as much as if it was 4:3 aspect. It's more work space and immersive, so long the movies and games support that different aspect ratio (else you will get those black sides).

Remember it's not just about being so close to the monitor where you can see the pixels but having to move your head / eyes a lot more when it's that close.

Even a 27 inch 1440p monitor can be hard to maintain complete coverage without having to move your head / eyes that can cause issues for some not to mention even more so for gamers where they need to see the entire screen in some games.

3840x2160 is exceptionally beneficial in games that would typically require advanced anti-aliasing techniques and increased draw distance, it is very useful in open world games.

2560x1440 is a definite step up from 1920x1080 but 3840x2160 will show a major improvement if you are gaming on a screen that is above 30" inches.

If you plan on gaming at 3840x2160, you could consider buying a television with HDMI 2.0 or DP 1.2 as the extra size will be more beneficial at that resolution. You can even buy a mouse and keyboard tray to play games from the comfort of your sofa.

and if you have not sli, you will have 30fps.... and it will look so crappy.

I think he's talking about getting a game console :)

Television != PC Monitors

Television uses a trick to blur pixels together, this allows better viewing at a distance, but isn't actually as high quality if you wanted to look up close and read small text on the screen for example. It depends how you like to play I guess, if you are happy sitting back on a sofa gaming like if it was a console, then it would be fine.

However, you also need a GTX 1080 or 1080 Ti, else SLI of multiple high-end graphics card to be able to perform UltraHD 4K @ 60Hz. Most UltraHD 4K will run at 30Hz (split).

unfortunately a lot of games dont support ultra wide (CSGO and Fallout 4 for example). CSGO isnt as bad, it just runs 2560x1080 res at 16:9 aspect ratio so theres like 1 inch on the top and bottom of the screen i cant see. But on fallout 4 it is horrible it stretches the whole game out and makes it blurry or i have to play in a 1920x1080 window on my desktop which sucks.

its weird to me to sit in a couch with a keyboard and mouse lol i just stick with a desk for my pc and a couch for consoles.
