Описание к видео [Hindi] What is PPI in Mobile? Do you really need 1440p or 2160p on smartphone?

Higher PPI- pixel per inch on smartphone leads to better clarity and detailing on screen resolution. With smartphone manufacturer rolling out phones with 400 or more PPI, it becomes important for user to know whether one really needs higher PPI.

While watching content on smartphone one can differentiate between HD & Full HD resolution but it becomes hard to differentiate between QHD and 4k because mobile phone screen size is too small for any such distinction.

It’s difficult for human eyes to differentiate beyond 300 PPI:

My personal recommendation is that one should not bother a lot about screen resolution. It’s quite decent to go for 1080P screen resolution.

If you are looking at using a VR headset then i will recommend you to go for high PPi on your smartphone as that will enhance your viewing experience.

Tutorial also explains:

-Resolution of video recording and screen resolution are two different things.
-Aspect ratio overview.
Higher the resolution greater will be the PPI.

You can also calculate PPI if you know screen size and resolution: we need to use pythagoras theorem

Example below -
Screen size 5.2 inch - Resolution - 1080 X 1920p
1080 X 1080 + 1920 X 1920 = 1166400 + 3686400 = 4852800
Square root of 4852800 = 2202.907
Above figure divided by 5.2 - screen size
We get PPI - 424.

Same way one can calculate Pixel per inch if you know screen size and resolution.
