HDTVs offer a 16:9 aspect ratio, which is similar to a movie theater screen, and available with higher-resolution screens, which impress with their clarity, color, and detail. Lifewire Resolution is HDTV's biggest selling point. We compared 720p, 1080i, and 1080p to help you make the best choice for your TV viewing pleasure. The 1080p has all but replaced 1080i. You can still find TVs with 1080i screens, but they're less common. Overall Findings 720p 1080i 1080p 1280 pixels x 720 pixels. 1920 pixels x 1080 lines. 1920 x 1080 pixels. Progressive scan: Draws all pixels at once. Interlaced: Split into two groups of 540 lines each. Progressive scan: Draws all pixels at once. The three HDTV resolutions are 720p, 1080i, and 1080p. The number stands for the number of horizontal lines that create the image, and the letter describes the type of scan used by the TV to display the picture: progressive or interlaced. Resolution matters because more lines mean a better picture. This is a similar concept to digital photos and how dots-per-inch determines print quality. 1080i and 1080p are higher resolutions than 720, but they aren't the same. You should go for 1080p because of the more efficient way it projects images onto the screen. Screen Resolution: Bigger Is Better 720p 1080i 1080p 720 horizontal lines. 1080 horizontal lines. 1080 horizontal lines. Progressive scan. Interlaced scan. Progressive scan. In general, the higher the resolution of a TV, the sharper the picture, and the higher the price tag. 720p has an image resolution of 1280 pixels by 720 lines. It was the first available HDTV resolution but is no longer as common since prices have come down on 1080 models. By comparison, a 720p TV has twice the resolution of an analog TV picture. 1080i has a resolution of 1920 pixels by 1080 horizontal lines. However, it is interlaced, so the lines are painted on the screen in two passes of 540 lines each. The picture quality is fine for slow-moving content but not as desirable for fast-moving objects. 1080i was once the standard in HDTVs, but no more. Its quality is not much better than 720p TVs. 1080p has a resolution of 1920 by 1080 pixels, and it is a progressive scan display rather than interlaced. That means each row is scanned in sequential rather than an alternate order, providing a picture with a full 2.07 million pixels. This is currently the best-selling TV format, and it provides the best picture of the three models mentioned here. Price: You Get What You Pay For 720p 1080i 1080p More affordable. More expensive. Most expensive. The price of a high-definition TV varies widely. It depends on many factors, including brand, features, and display technology. The type of display is one part of the hardware. Other factors that contribute to the price include display size, availability of smart features, and screen type (LCD or LED). In general, 720 screens are cheaper than 1080 screens. Within the 1080 tier, progressive-scan displays are more expensive than interlaced. But, depending on the other factors, these comparisons may not always be the case. Final Verdict Assuming all three of these TV formats are in your price range, 1080p TV is the best choice. The 720p and 1080i models rely on old technology that is gradually giving way to higher-resolution options. A 1080p device offers the best resolution and viewing experience. However, for TVs that are 32 inches or smaller, you won't see much difference between pictures on 1080p and 720p displays.
