Display Diagonal vs. resolution – what it is important

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.

When the resolution is as high as possible

A higher resolution leads to a finer and more detailed image – if you want, closer to reality. A 4K screen will have about twice as many pixels as an HD one, and if the two are as large, the pixels of the 4K will be twice as small as the other, which means that they will be much harder to perceived by the human eye, which drastically improves the image.

Therefore, a high resolution should come bundled with either a large TV, so that individual pixels are difficult to detect, or with a screen designed for short-distance viewing.

You will notice that PC monitors often have very high resolutions, even if their size is smaller than LED TVs, because they will be viewed from 40-80 centimeters away by the user.

To draw a conclusion here, we can say that the resolution is much more important than the diagonal, when it comes to image quality. It also matters the type of technology used in the display (OLED, AmoLED and so on), but in this section we will not address this complex topic.

When it is a large size impediment

Here, things are simple: a very large TV diagonally may be undesirable, when the room you want to place it is small and viewers will be very close to the screen.

However, we can add another reason: a large display also involves a high weight of the screen, and in this case, if you intend to attach the TV to awall mount , then you will have to be very sure both the resistance of the mount and how you fastened the wood screws to the wall material.

Otherwise, the TV may fall off suddenly at some point, and how sensitive these devices are, such a fall will almost certainly destroy the screen. Also, we advise you that if you place a large TV on a shelf, be careful that it is firmly attached to the wall.

We can also add the fact that a large diagonal TV could be difficult to place in the corner of a room, because in such locations, the larger the device, the more it will have to be placed away from the corner to fit.

When an impediment is high resolution

On this subject, we will start by saying that too high a resolution will not bother the eyes – it is not possible to discuss such a thing. But it will upset your pocket. In short, the more pixels your desired TV has, the more expensive it may be than a similar, low-resolution model.

But, there is also good news: if you have been paying attention to the LED TV market in recent years, you may have noticed the trend of cheaper high-resolution devices. When the Full HD standard appeared, the models were quite expensive and gradually became very affordable.

Likewise, when 4K resolution became the latest novelty, a TV of this type was inaccessible, but today you can buy it without much financial effort. For this year, we may see the emergence of the 8K standard, but at exorbitant prices.

Technology enthusiasts, with considerable funds, might consider investing in such a thing. We discuss this decision in the last piece of our section:

Is it worth investing in an 8K?

This has been the question of many media enthusiasts lately. 8K standard TVs will soon appear on a large scale, but at very high prices. The dilemma is this: will the human eye perceive a considerable difference between 8K and 4K to justify the financial effort?

The answer is that it may take an eagle's eye view to say "YES" and many people will say "NO". At the same time, an 8K resolution may be desirable if you want a monumental TV that occupies the entire wall – at such sizes, the difference would be seen, compared to a standard 4K.

Of course, you will also have to have the income of an Arab sheikh or a Russian oligarch to make such an acquisition. It remains to be seen how successful 8K TVs will be, if they will catch or if they will remain a curiosity without a future.
