1080i is a way to display videos and high-definition television screens (HDTV). It means a video mode with a vertical resolution of 1080 odd and even lines. "I" stands for interlaced scanning mode. 1080i display format: Each image displays twice because a picture is painted alternatively in this format, meaning that odd-numbered lines get painted first, then even-numbered lines. In the past, this format was common in HDTV. Broadcast television uses it, especially because it only requires a little capacity to create high-resolution images.
The pixels in the 1080p display format are arranged in rows or lines. 1080p refers to progressive scanning that is non-interlaced. A high-definition image mode will be 1080p if characterized by 1,920px horizontal and 1,080px vertical. It is also known as full HD or UHD and works well with various media, such as televisions and monitors. The term generally implies a widescreen aspect ratio of 16:9, with a resolution of 2.1 megapixels.
To discuss the difference between 1080i and 1080p, we'll review the symbols: 1080i stands for 1080 interlaced scan and 1080p for progressive scan. You'll see both formats differently on your screen. In an interlaced scan (1080i), odd and even pixel rows are alternatively illuminated to display the image. It happens so quickly (each field flashes 30 times per second) that your eyes don't notice the switch, so you see what appears to be a fully assembled picture at any given moment. Each image is displayed twice in interlaced (1080i ) display format. Old televisions using cathode-ray tubes used this display mode.
However, progressive scanning mode (1080p) refreshes each row of pixels on the screen 60 times per second. Progressive scan creates better HD content than interlaced scan, which is more technically challenging. Because of this, 1080p is often sold as "true" or "full" HD by those who want to set it apart from 1080i or 720p. Look at the images below and notice the differences in detail and clarity.
The benefits of progressive scanning are particularly noticeable in scenarios with moving objects. The progressive scan provides the viewer a smoother experience by displaying the full range of motions. That's the majority of modern computer screens and televisions use the 1080p display standard.
Blu-ray discs, streaming services, video games, and high-quality video production typically use 1080p resolution. It generates a clear, crisp image, making it ideal for larger screens where minor details stand out more.
The quick and easy answer is that '1080p' is better than 1080i because 1080i technology is usually invisible to the human eye. 1080p offers specific benefits for use with a lot of motion. In the case of the 1080i display format, fast-moving images may have shifted from the first field to the second. It can create an almost blurry and irregular image for the user.
1080p resolution avoids this problem, displaying much better image quality in fast-moving scenes. 1080p scan offers smoother motion than 1080i, especially for action scenes.
In addition, most people prefer 1080p because it is typically more realistic and colorful. Because the even and odd rows of pixels aren't shown simultaneously, like 1080i, the image quality is higher (after around 60%). In other words, 1080i and 720p have similar resolutions. So, 1080p is better than 1080i.

'1080i' games can feel hazy when objects that move quickly are on screen, so 1080p is much better for gaming.
720p and 1080p differ mainly in terms of video resolution. Because FHD has a higher resolution than HD, more pixels can fit on the screen, creating crisper images.
