When buying a LED screen, doubts often arise. One of the most common is how to select the right pixel pitch. It is natural to want to get the best image quality. In fact, it is easy to find examples of  bad pixel pitch choices: distorted images that cannot be perceived correctly at any distance.

Some people (and sellers) believe that distance from the screen is the only variable that matters to get the best image quality. They mistakenly calculate pixel pitch based only on this and do not think about the size of the LED screen.
As technical advice, the first thing you have to do is to calculate the total number of pixels that has the screen we want to buy. The amount cannot be less than 30.000 pixels.
