Is 1080i Better Than 720p?

In the case of digital television, the monitor for computers or display resolution is an essential aspect. Because it’s the highest amount of different resolutions that are available in any dimension. The higher quality resolution of the image for particular screen size is due to the more significant number of dots in the picture. 1080i and 720p are part of the same resolutions family but have distinct characteristics and uses.

What is 1080i?

Two pairs of pixel resolution are expressed in the 1080 interlaced format, each set appearing after the other. The process is carried out where one image is spread across the even lines of an image field using an interlaced format 1080, and the other image is transmitted across the odd lines images.

The 1080i image will be sent as an interlaced, meaning that each frame of 1080 lines is rendered twice. In the beginning, all the odd lines beginning at 1079 and 1 are drawn. From two to 1080, all odd lines will be removed. The entire sequence is described as a field. The 1080-line frame comprises two areas, each included of 540 lines.

In the end, our eyes require more time to look at a full frame when watching an interlaced image. This process helps to create creating the illusion of motion and may help eliminate problems like screen flicker.

In a 1080i format, only 540 lines are broadcast every 60th second, and the remainder of the data is published each 30th second. The effects of interlaced 1080 techniques may be different based on various aspects. The variance between other scan-type formats can be diminished by using a smaller TV. It is also crucial to consider how service providers handle compression algorithms.

What is 720p?

It is a picture with 1,280 pixels in 720 rows. For example, if you take an LCD TV or similar display device, pixels or horizontal lines of 720 rows are displayed in chronological order. That is, each row or line is displayed one after the other.

This was the very original HDTV resolution format to be made available. In contrast, it has twice the resolution of analog television. For every sixtieth second or every 30th of a second, the display is regularly kept up to date. In the context of digital cameras, the total amount of pixels on the 720p full screen is 921,600, which is about 1 megapixel.

There are various parameters on the hours of a movie depend. The amount of time spent on HD video is based on several factors, such as the quality of the video, the camera’s bitrate, and the video’s frame rate. A memory card of 32GB could contain anywhere from 3 to 5 hours of high-quality 720p video on average.

Progressive scan, also known as non-interlaced, is indicated using the letter. The 720p format is the highest resolution for temporal data available within the ATSC and DVB standards for broadcasts in 60 frames per second. It is a widescreen 16:9 aspect ratio. This means that it has a resolution of 1280×720 pixels.

Main Differences Between 1080i and 720p

The main difference between 1080i and 720 is the display technology options differ for both resolutions. The letter I stands for the overlaid scanning type 080i. But the letter p stands for the gradual test, which is what 720p is.

  • 1080i’s resolution is 1920×1080 pixels which make 2 million pixels when multiplying. 1080p has a resolution of 1280×720 pixels, giving less than one million pixels when bearing.
  • In 1080 interlaced format, it’s split by 540 lines, and in the 720p scan format, the pixels are drawn at once.
  • 1080i is a screen of 1080 vertical lines, whereas the 720p screen has 720 lines horizontally.
  • The most commonly used HDTV format is the 1080i, which is used for standard HDTV standards for broadcast by most TV broadcasting, cable, and satellite broadcasters. Also, 720p can be used for high-definition (HD) video quality.


The two-screen resolutions 1080i and 720p both have their HDTV applications and usage. The 1080i resolution is an interlaced resolution with 1920×1080 pixels, and on the other hand, The 720p type is a progressive one with 1280×720 pixels. The significant difference between them is the screen resolution and scan type format, which can result in different applications.
