4K, 2K, 1080p What is The “Good” Resolution for a TV?

What resolution is appropriate for television? The manufacturers of consumer electronics are in a permanent race to add new functions and technology to the devices they manufacture so that we, as consumers, cannot resist and change our equipment yesterday for brand new stuff the day after tomorrow. This happens in any segment but is unusually intense in the case of televisions and their resolutions, which have gone from 720 to 1080 and now 2K, 4K or even 8K.


And here began a curious phenomenon. Anyone who saw one of those 720i televisions at that time will remember that their image was better than what exists so far. It was a great leap in quality. But the same thing happened with each new advance. When moving to higher resolutions the new and improved resolution looked better and more clearly and what until then was the highest level of quality, at that time, being able to compare it with a superior one, evidenced its limitations and lost its appeal. Each new standard immediately made the old one obsolete, which it left obsolete regarding image quality.

The evolution of electronics made the 720i come up with an improved version, 720p (from progressive or progressive, which painted all the lines of the image in a single frame). And these were followed by the semi-standards of 1080i and 1080p. Yes, you guessed it, they have 1080 vertical lines that, in one case are drawn interlaced and in the other progressively. Each resolution increase results in an image with more details, but the resolution, as with the sound power of the audio equipment, is only part of the story. The electronics that are responsible for processing these signals can be mediocre, correct or spectacular.

And that will result in moving images with mediocre, correct or spectacular fluency, color reproduction, and sharpness. As in a sound, equipment is not the same to have a sound of high volume and quality mediocre or correct than a spectacular one. The rest of the TV should be up to the resolution of your screen. Although that’s another story. Today we will focus on the crazy career of high definition LED TV , which is not little.


In case this jungle of terms is not enough, many top LED TV brand in India have used different ones. Here is a summary of the main resolutions and their names:

  • 720p (1,280 x 720 pixels): known as HD or High Definition.
  • 1080p (1,920 x 1,080 pixels): also called Full HD, FHD or 2K.
  • WUXGA (1,920 x 1,200 pixels): Acronym for Wide Screen Ultra eXtended Graphics Array.
  • 2K (2,048 pixels horizontally).
  • UHD (3,840 x 2,160 pixels): known as 4K, Ultra HD or Ultra-High Definition.
  • Cinema 4K (4,096 straight points): it is also simply called 4K.
  • 8K (7,680 x 4,320 pixels): still experimental and for now without more synonyms.

In televisions, you will find resolutions of 7

20p, 1080p, UHD or, in experimental models, 8K. WUXGA, 2K or Cinema 4K resolutions are often used with monitors or projectors. In the end what never fails is that, when in doubt, you base yourself in the resolution of the screen. That is, even if they offer a model like UHD, you ask them to give you the data of 3.840 x 2.160 pixels to know if it is the same or not that another screen with which you are comparing it.
