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.
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.
