Difference Between 1080i and 4K (With Table)

Over the last decades, higher resolution has been the buzzword for televisions. It started with color, then HD, then 720p, 1080p, and finally 4K. Is it always better to have more resolution? When does resolution cease to be important? After all, the human eye can only perceive a certain amount of detail, right? So, to understand the answers, continue reading the article.

1080i vs 4K

The main difference between 1080i and 4K is that the 1080i is known for full HD screen, and on the other hand, a 4K screen resolution is four times better than the 1080i screen resolution in terms of pixels. 4K is the advanced version, but the difference can be seen on the larger screen.

1080i is known as full HD, which has 1080 vertical pixels. The ‘i’ stands for interlaced scan, and this pixel is formed when 1920Ɨ1080 of two million pixels are multiplied. This resolution is commonly used in TV broadcasting, satellite portals, etc.  

4K simply means that the resolution will be 4000 pixels which is four times the pixel of full HD, and this difference can not be seen by naked eyes and on a smaller screen. But the quality of the video is far better than any HD display.

What is 1080i?

An interlaced scan with 1080 horizontal lines of pixels and 1920 vertical lines is known as a 1080i resolution. This improves picture quality to 720p; however, many people complain that the picture does not flow well because of the interlacing in the frames; thus, they prefer 720p instead.

Since the phrase specifies a 16:9 widescreen aspect ratio (a rectangular TV that is broader than it is tall), 1080 lines of vertical resolution equate to 1920 columns of horizontal resolution, or 1920 pixels 1080 lines.

A screen with a resolution of 1920 pixels by 1080 lines has an overall resolution of 2.1 megapixels (2.1 million pixels) as well as an estimation of 50 or 60 interlaced frames per second.

1080i is fully compatible with certain CRT HDTVs, on which it could be viewed in interlaced mode, and it should be deinterlaced for projection on progressive-scan TVs, such as most contemporary LCD and plasma TVs. 

Most HD satellite television networks stream in 1080i around the world. The majority of programmers in the United States choose 1080i, including Discovery, Inc., ViacomCBS, WarnerMedia, and Xfinity-owned networks, as well as most local broadcasters, airing in the resolution.

What is 4K?

4K has become quite popular due to the increase in availability options. It has only recently become a reasonably realistic option for most, with SkyQ, Netflix, and BT Vision now selling 4K content as well as inexpensive 4K Blu-ray recorders. 

Based on the TV supplier, 4K is sometimes known as Ultra-HD or UHD. However, the vast majority of people believe that the 4K pixel is mainly composed of 2,160 horizontal lines and 4,096 vertical lines of pixels. 

In comparison to earlier resolutions, 4K is unique in that it specifies the horizontal resolution instead of the vertical resolution.

When contrasted to earlier resolutions, it’d be recognized as 2160p, which does not seem nearly as expensive.

In technical terms, UHD is an image of 3,840 horizontal lines and 2,160 vertical lines, or 3,840 x 2,160. Even though it is close, it is not quite the same, but that does not stop several manufacturers from labeling their TVs as 4K.

4K is capable of producing some truly amazing images. It is claimed that the naked eye cannot see much clearer than our present sized TVs.

Main Differences Between 1080i and 4K

  1. The pixels on a 1080i screen are lesser. Of course, you’ll need a screen large enough to detect the difference ā€“ often around 50 inches or bigger. On a 4K TV, you may see substantially more information, and movies will likely appear clearer overall, thanks to roughly four times the number of pixels. 
  2. 1080i does not have better resolution than 4K, and 4K TVs have a color advantage due to their more pixels. They can produce significantly more vibrant colors and deeper depths than 1080i TVs. In this area of technology such as OLED and HDR have a stronger impact, yet the resolution is still important.
  3. 1080i resolution systems do not have that high quality of the sound system, whereas 4K resolution television has better sound quality and HDR and Dolby Atmos installed.
  4. Most of the content available, like TV shows or movies, is in 1080i resolution. Not every broadcast channel has used 4K resolution, and even if you have a 4K display, you will end up watching in 1080i resolution. 
  5. However, the 1080i resolution screens are budget-friendly. The price of 4K TVs has been reduced in the meantime in the market and the manufacturer costs, but they are still higher in price than 1080i TVs. 


Now that we have gone over the pluses and minuses of both benchmarks, the real question is where you should invest your money.

We would need to learn more about your case to give specific advice. Any of you with an expendable income of $300 or more, on the other hand, should consider 4K without hesitation. If money is not an issue, you might as well go for the future-proof choice.

4K is the technology of the future. Whereas many providers continue to broadcast in 1080i, massive companies are switching to 4K. Some Netflix, Disney Plus, and YouTube videos are already available in 4K, so it is only a matter of time, and you should use the advanced technology.
