what each resolution means and how they differ

You are about to buy a monitor or television. You walk your steps to the store or type in the appropriate web page address and start looking at alternatives and diving for the specs. Screen diagonal, price (it is very important) and some acronyms that stand out from others. The resolution… one of the excuses used by brands for us to change models from time to time although many times, if we think about it, we don’t need.

The fact is that the battle of acronyms on packaging is overwhelming. HD, Full HD, QHD, UHD, 4K, the very meager 8K … a whole dance of letters which may not represent a problem for you but it may raise doubts for some users. And they are the ones we want to guide with this article.

Resolutions for all tastes


With these acronyms we are referring to the resolution offered by a screen but before continuing, do we know what resolution is? Is about how to calibrate the number of pixels that make up the panel on a screen, with pixels being the smallest part into which an image can be divided.

Therefore, we understand by resolution the number of vertical and horizontal lines made up of pixels that a screen can display. Lower resolution means fewer pixels and worse image quality. And the same thing happens in reverse, although there comes a time when the human eye no longer perceives the difference between more pixels per inch (dpi).

A matter of figures


Normally, when we are going to buy a monitor or a television at this point, we are going to have to choose between two variants or at most three. Is about Full HD, UHD o 4K (we already said it’s not the same although they want to sell it that way) and 2K or QHD (it is more frequent in monitors but not in televisions. 8K is above, but there is still to see it arrive en masse.

Each of these resolutions is usually accompanied by figures of which we will take as an example Full HD and its 1,920 x 1,080 pixels. And what do these numbers mean? Well, we go back a few lines above and remember; the image is made up of horizontal and vertical lines of pixels, so this figure indicates 1,920 horizontal and 1,080 vertical pixels. In total, 2,072,600 points of light on the screen.

When size matters


In this way we can clearly see the difference and that is It is not the same to appreciate image quality and definition having 1,920 x 1,080 pixels on the screen (2,073,600 in total) than 3,840 x 2,160 pixels (8,294,400 in total) which is what a UHD screen offers, at least in theory. In the latter the content will have a greater definition.


Here, however, the screen size also comes into play, the famous diagonal. And it is that an HD television (720p) can be seen very well on a 32-inch screen while that same resolution becomes “infumable” if we place it on a 55-inch screen. The reason? Few pixels to cover a larger surface area, resulting in overly pixelated images and poor image quality.

Currently the resolution most used in televisions and monitors is Full HD (1080p) Although little by little it is being displaced by what is called to be the new standard, the UDH resolution, which is gaining ground thanks above all to lower prices, including those that are increasingly accessible OLED panels.

Is so much resolution necessary?


Well, it depends above all on the use that we are going to give it, the price and the type of device. In the case of televisions, currently if we find a good UHD option it is interesting to get it especially if we come for example from an HD or Full HD model. In this way we can, for example, have access to content in UHD with HDR increasingly common either in Physical format The streaming.

In the case of a monitor, it is almost the same with the exception that to make use of 4K in video games we will require a very powerful computer or a console like the Xbox One X so if this is not the case, a good Full HD monitor may be enough (here each user sets their limit).
