1080i vs 1080p: What’s the Difference?

1080i and 1080p are both high-definition resolutions for televisions. But what’s the difference? And which one is better? In this blog post, we will discuss the differences between 1080i and 1080p and help you decide which resolution is best for you.

The Whole Story of 1080i and 1080p

Charles Poynton made 1080i in 1990, and 1080p was changed in 2004. Because of this time difference, 1080i is still used. The old 1080i systems are being replaced by 1080p systems slowly but surely. It would be too expensive for not much gain to change everything at once, so 1080p will slowly become the new standard over time. Since TVs and cable boxes have converters that can change 1080i to 1080p, there is no rush to get rid of 1080i broadcasts. Each choice has so few pros and cons that any problems or benefits are at best small. Since 1080p is better, it is becoming the standard for 1080 resolution in new media and devices. Even better is 4k, but we’ll talk about that another time.

What is 1080i and 1080p resolution?

1080i and 1080p are both high definition (HD) resolutions. 1080i is an interlaced resolution, while 1080p is a progressive resolution.

The main difference between 1080i and 1080p lies in the way each format displays images on your screen. 1080i resolution delivers images in two fields. First, the odd lines are displayed, followed by the even lines. 1080p resolution, on the other hand, displays all lines in a single frame.

The 1080i format is better suited for fast-moving images, while 1080p is better for displaying static images. If you’re watching a lot of sports or action movies, 1080i is the way to go. If you’re more interested in movies or TV shows with static images, 1080p is the better option.

One thing to keep in mind is that 1080i and 1080p use the same number of pixels. The difference lies in how those pixels are used to create the image on your screen. So, if you have a 1080i TV, you can still watch 1080p content. The image will just be displayed in 1080i resolution.

Which one should you choose for your home entertainment system?

The 1080i vs 1080p debate has been going on for years, and there is no clear consensus. Both have their advantages and disadvantages, so it really comes down to personal preference. Here’s a quick rundown of the differences between 1080i and 1080p:

1080i has a higher resolution than 1080p, but it doesn’t look as smooth because it uses interlacing. 1080p has a lower resolution than 1080i, but it looks smoother because it uses progressive scanning.

So, which one should you choose? If you want the best possible picture quality, go with 1080p. If you’re more concerned about smoothness, go with 1080i. Ultimately, it’s up to you. Try out both and see which one you prefer. Whichever one you choose, you’ll be getting great HD quality.

Pros and cons of each


  • Higher resolution than 1080p
  • Can look choppy because of interlacing


  • Lower resolution than 1080i
  • Looks smoother because it uses progressive scanning

If you want the best possible picture quality, go with 1080p. If you’re more concerned about smoothness, go with 1080i.

7 things you must know about 1080i vs. 1080p

  1. 14 years went by before 1080p was made.
  2. 1080i and 1080p mean that the resolution is 1080 lines, but the scan is either interlaced or continuous.
  3. The resolution of both 1080i and 1080p is the same.
  4. 1080i takes up half as much space as 1080p.
  5. 1080p has twice as many updates per second as 1080i.
  6. 1080i has trouble with a video that moves quickly not being clear.
  7. Most TVs and cable boxes can automatically change from 1080i to 1080p.

1080i vs 1080p: Side-by-Side Comparison

When you put 1080i and 1080p next to each other, you can see how they are the same and how they are different. Everything looks the same until you look at the refresh rates and the number of pixels. 1080i is only able to handle half as much data as 1080p.

Meaning:1080 interlaced scan display pixels format that forms an interlaced display by 1920 pixels horizontally and 540 pixels screen vertically.1080 progressively scan display pixels format that forms a non-interlaced display by 1920 pixels displays horizontally and 1080 pixels screen vertically.
Screen Ratio:1080i covers the screen aspect around 16:9 i.e, 1920×540 pixels.1920×1080 pixels, i.e, 16:9 screen aspect ratio.

Support:1080i is highly used in cable broadcasts, satellites, and HD channels for high-quality video format.Many electronics employ 1080p as a common display resolution on PC monitors, gaming laptops, TVs broadcasting, Blu-ray discs, smartphones, projectors, and cameras.

In short,

The way the display lines are scanned is what makes the two methods differ. In a progressive scan, the lines are shown one after the other in a single pass. In an interlaced scan, the lines are shown in two fields, each of which shows half of the lines at a time.

An interlaced scan is an old technology that is no longer used in TVs, monitors, or digital microscopes made today. But it’s still important to look at the technical specs before buying new technology. The frame rate has a big impact on how smooth the image is and how well the operator can use their microscope for visual inspection processes. It’s also important to know if the frame rate will change if you’re using a monitor or a computer screen for your inspection.
