Any display you use is made up of tiny dots which are known as pixels or picture elements. Each pixel on your screen changes its colour and brightness to create an image on the screen. The screen resolution of a display is used to specify the number of pixels on your screen. So if your screen has a resolution of 1280×720, it signifies that your screen has a total of 9,21,600 pixels and these pixels create the image on your screen.

In the term mentioned above, the first number indicates the pixels in the horizontal direction, and the other represents the pixels in the vertical direction.

Now that we have a basic understanding of how displays work, we can take a look at all the resolutions which are available in the market and which one is best for you.

DPI and screen resolution

Another important parameter related to a display is its DPI or dots per inch. This term is used to define the number of pixels in one square inch of the display. A higher DPI signifies higher pixel density which offers better picture quality.

If you have two displays with the same resolution with different screen sizes they would have a different DPI. As an example, if you have a 25-inch monitor and a 32 inch monitor both having an FHD resolution, the 25 inches would have a DPI of 88 while the other would have 69 DPI.

Although its better to get a display with higher DPI anything above 400 DPI is overkill and the human eye cant differentiate between screens with a higher DPI.
