The monitors are chosen according to the resolution, this indicating the way in which the image is rendered, more precisely the maximum number of pixels. The larger the display, the higher the resolution must be, in order to observe every detail as clearly as possible. The question is whether there is so much need for 4K screens, if we refer to monitors. Well, not necessarily. 4K content is not so popular that you need it. Yes, it is more and more common, but the vast majority of games and movies are in Full HD format. In addition, the screens are not so large that they need such clarity.
It is important to know as much detail as possible about the resolution, in order to be able to choose a monitor knowingly. Next, we will present you the most common variants and the characteristics they have.
HD / High Definition / 720p
This is the resolution considered to be the weakest when it comes to computer screens that can be purchased today. When it appeared, it was much appreciated because it offered a much better quality than Standard Definition (SD), which meant 720 x 480 pixels.
HD monitors have 1280 x 720 pixels, where 720 means that this is the number of lines vertically and 1280 horizontally. In this case, you encounter a refresh rate of 24 // 25/30/50 or 60 Hz. The bigger it is, the better, because the faster the sequences with which the frames will be displayed are. The aspect ratio of the image at this resolution is 16: 9.
Now, you can hardly find new displays with this specification, because it is already too old to interest anyone. It is present on the variants that have not been replaced or maybe on the ones that you buy second hand.
