The discussion we will address in this section of Info is about the two main parameters that are mentioned in the description of TV screens, but also monitors: diagonal, ie the distance between any two opposite corners of the display, and resolution, ie the number of pixels on it, described as a product of two values, the number of pixels on the width x the one on the length.
When one is more important than the other and what is the relationship between the two aspects, we discuss in the paragraphs below:
When size is important
Broadly speaking, we can say that the size of a screen – represented by the diagonal – should be chosen depending on several factors, namely the size of the room in which you place the TV and the distance from which you look at the screen.
A large camera would benefit from a tailor-made TV system, so that you can watch the images of shows and movies without getting tired of your eyes. Imagine what it would be like to try watching a small screen (say, 48 centimeters) on a sofa 3.5 meters away from it. You need eagle eyes to understand something. Things will be different, if you replace that TV with a 120 cm diagonal, right?
In addition, if you do have considerable funds, you may even want a screen that is disproportionately large compared to the room in which you place it. Let's say you chose a 140 centimeter TV model and put it right in front of the bed, in the bedroom, that is about 250 centimeters from your eyes.
You could enjoy the image, as long as the screen resolution is high – a 4K would be optimal, in our example. Otherwise, your eyes will see individual pixels, which would make your eyesight considerably tired.
