What The Hell Is 4K ?

You have probably heard the term 4K for a couple of months and it been a sort of buzz word. So what does 4K actually means.

It is quite theoretical rather than technical.4K is a resolution actually and is measured in pixels like any other resolution. You can see smartphones nowadays having an average resolution of 1280 x 720 pixels (i.e. 720p), the average laptops say with a slightly bigger display have resolutions around 1440 x900 pixels and the larger desktop displays have resolution around 1920 x 1080 pixels (i.e. 1080p).

4K displays are somewhere around 4000 x 2000 pixels, because 4K actually varies there isn’t a standard  4K but the closest to 4K is called UHD (Ultra High Definition) i.e. 3840 x 2160 pixels which a lot .

In terms of pixel density, we know that higher the pixel density the better it looks, more clear and more sharper it looks. It also depends on the viewing distance. Like our smartphones we use them a couple of inches from our eyes therefore they need to have higher pixel density (which should be around 300 ppi) because we can see those pixels if the pixel density is low. A laptop since you hold it at a distance from your face doesn’t need to have a higher pixel density, considering a 15” laptop with above resolution has a pixel density of 120ppi which is quite good for a laptop. When you  see at a bigger screen from a distance say a 55” 1080p TV you get to a pixel density of 40ppi which seems low as compared to a smartphone but sitting around 7 or 8 feet away you will never be able to see those pixels at 40ppi.

At some time in your life you have walked up to the TV and have seen those red and blue pixels. But in 4K you would never be actually able to see those pixels. a 55” 4K display would have around over a 100ppi which means you can stand an inch away from it and still not able to see the pixels. And looking at it from a distance would be simply amazing with all that sharpness you will get that surreal realism with it.

 Although it is quite incredible but there is a problem with them they are quite expensive, alright! They are really expensive not like 60000 or 70000 but like a new car, 300000 Indian rupees. But around 2-3 years later their prices are likely to come down. You can wait till that or you can sell your car to buy a 4K TV.
