Both denominations have the same number of pixels, indicating 1920×1080 resolution, but they operate differently. The difference between these two denominations has to do with the frames that appear on the screen. Normally we will not notice the difference, but it exists and is particularly noticeable in competitive video games.
Difference between 1080p and 1080i resolutions
We reiterate that for both resolutions we have 1080 horizontal lines and in each of these lines we have 1920 pixels. What changes between them is how each frame or frame that makes up a video is updated.
The 1080i format what it tells us is that it is a “intercalated” resolution“. What it tells us is that the images are interlaced, which is a way of exposing the images or frames. Images or frames do not appear completely in the transition between frames, but are “split”. First are distributed odd horizontal lines and in the sequel the change is complete with even lines. Normally this change is not noticeable, but in competitive games it could be a problem.
During this time he 1080p format, what it tells us is that it is progressive. The frames or pictures displayed gradually one after the other. This means that even and odd rows are displayed at the same time.
Let’s say we have a video of 1920×1080 resolution who offers 60 frames per second (60 FPS). In the format 1080p what we will have is that will display 60 images per second. While in the 1080i format will be shown 30 frames per second, half. It is explained that for every frame “scan” in 1080i, two scans or frame updates are required, whereas in 1080p this only happens once.
In the 1080i format we have major problem and it’s quite common tear. This problem is basically display two images simultaneously, see the image as if split. An effect usually occurs in video games.
Choose well for video games
As we mentioned, the 1080p formatwhen loading an image or a full frame, you can offer the double pictures per second than in 1080i resolution. Although sometimes hard to spot, in games like CS:GO, Fortnite or similar, yes, it can be perceived more easily. These are action and fast games, where the load on the graphics is high and the shortcomings of the 1080i format are noticeable.
Indicates that the 1080i format is generally used in DTT broadcasts and sporting events. The television converts to 1080p and it is very rare to see these visual issues on the screen.
If you are planning to buy a monitor for 1920×1080 resolution, you need to verify that it is 1080p and not 1080i. It must be said that it is extremely rare to see monitors with this format, but it can be seen in inexpensive monitors, especially for office automation or multimedia.
