The abbreviation PPI stands for “Pixel Per Inch”, that is, pixel per inch. This value indicates how many pixels are placed in one square inch of the actual monitor size. The total number of pixels is calculated using standard formulas for the area of a rectangle or a right triangle, which each of us studied at school. The larger this value, the higher the resolution of the monitor.

The pixel density ppi determines the clarity and quality of the image displayed on the screen. With a large number of pixels will be very, very small, which will allow you to overlook the corners of these squares and create the illusion of a smooth transition between the objects displayed on the screen.
IMPORTANT! The image quality itself also matters - if a 20x20 pixel image displays a forest, then regardless of the strength of the monitor, the image will be “grainy”.
This feature is very important for those who work with images or videos on a computer or tablet. And, of course, for fans of computer games with high parameters of video quality, a large screen size will come in handy.
If we are talking about mobile devices (phones, smartphones, tablets, etc.), then too high ppi will be not only useful for them, but harmful. The output to the screen of a high-quality picture with a large number of pixels adversely affects the battery level during operation. That is, devices with large ppi will not be able to do without recharging for a long time.
How to adjust?
It is not difficult to adjust the size of the display on the PC screen. This may be required by those who have purchased a new monitor, or vice versa, wants to reduce the image displayed on the screen to save RAM and processor power. Necessary sequence of actions:
- Right-click in an empty area of the desktop and select "Screen Resolution". A menu will open where you can choose:
- Monitor (if there are several), which displays the action of the PC system.
- The resolution in pixels (there are many options, one of which is indicated as recommended), which is limited by the maximum screen size.
- Orientation (image format) of several options. As a rule, the default is the most convenient for perception at this resolution.
On mobile devices, screen properties can be adjusted in the Settings section. But not all phones provide their owners with such power over themselves.
