6 main differences between 1080i and 1080p

Choosing a TV or monitor in the store, you can come across display type is “1080i” or “1080p”. The permissions of these matrices are the same, but the image quality is different. And the difference lies primarily in the type of expansion. Exactly this the parameter differs in 1080i resolution from 1080p.

1080i interlaced format

Before understanding the differences between progressive and interlaced scan, you need to understand what a scan in general.

Scan – a way to display the image on the screen. She can be interlaced, interlaced and progressive. First option in the present is practically not applied, however it is still can be found in old CRT monitors or budget LED panels.

In line-by-line scanning, the first screen is displayed first. a line of pixels, then a second, then a third, and so on. This happens very quickly, so the human eye is not capable notice such a rendering. But you can see it if you look at CRT monitor through the smartphone’s camera (oblique will “run” across the screen stripes) or even try to take a picture of it (part of the image on the monitor it will be completely invisible, as if it was turned off).

Line scan remained a relic of the past, but before managed to “evolve” into more modern standard 1080i. The image is displayed on it. also sequentially. However, even lines are displayed first, then odd, then even again, and so on.

The change of stripes is so fast that the human eye not able to notice. The frame rate is about 30 frames each type per second (or 60 frames in general). Using standard 1080i is due to the fact that when the first such monitors, video cards for the most part were not able to calmly transfer a huge amount of data – and the video stream in Full HD has a very high bitrate. And I had to go to a trick. Every a clock cycle (1/60 second) of the video card transfers half the necessary Display Full HD picture data.

For 2019, the 1080i format may seem outdated. Not less, it is still on the market as it has a pair important advantages.

Advantages of the 1080i format

  • The monitors and televisions that support it are much cheaper than compatible with 1080p;

  • Allows old and weak graphics cards to pull the full Full HD resolution.

Disadvantages of 1080i format

  • “Flicker”, which in some people may cause increased eye fatigue and even headaches;

  • The lack of smoothing, which is especially noticeable in fonts and highly detailed images;

  • The appearance of artifacts in moving objects that are most strongly manifested in games or in very dynamic scenes in films.

Should i buy a 1080i monitor or tv in 2019 year?

Only if you have a very limited budget or a very old computer. In other cases, it is better to look at 1080p.

1080p progressive format

1080p format uses the so-called “progressive “. The entire image is displayed on the matrix in one cycle, and not line by line, like the predecessor. Thanks to this, get rid of flicker, as well as increase or decrease the frequency picture updates.

So, if the standard “i” has a fixed refresh rate and is 50 or 60 Hz depending on the region, then “p” supports decreasing or increasing the frame rate in the range from 24 Hz to 120 Hz. This is especially useful for gamers who use game monitors. A frame rate above 60 Hz allows you to do movements are smoother, and also display instantly appearing objects in sight.

But the main advantage of this standard is a high degree smoothing. Texts are easier to read and enjoyable regardless of selected font and size. Images with many small details look crisper. The movement of objects on the screen seems smoother, and also artifacts disappear at a high speed of movement.

Thus, 1080p per head surpasses its competitor. However, it also has drawbacks, and first of all it is – exactingness to the interface and high cost of equipment. 1080p especially with a high frame rate, needs a high speed connecting to the video card. And so it can be connected with a computer unless the interfaces are DVI-D DL, DVI-I DL, HDMI or DisplayPort. Bandwidth DVI-I SL or DVI-D SL can just not enough.


  • Superior anti-aliasing, enhanced image detail, no artifacts when moving objects fast;

  • Reduced eye strain, no flicker.


  • High price for compatible equipment – TVs, monitors and video cards (compared to 1080i);

  • Requires a high-performance interface.

Should i buy a 1080p monitor or tv in 2019 year?

Yes, this format is the most modern and enjoyable in use. Especially when it comes to TV or display for a “creative specialist.” Of course, the price of “p” monitors are higher than “i”, however these costs are completely self will justify.


format comparison

Summing up, we can distinguish the following difference between 1080i and 1080p:




Font anti-aliasing quality



Detail Level of Small Objects



The appearance of artifacts during the rapid movement of objects on screen

there is


“Flicker effect” leading to eye fatigue

there is


Compatible with older monitors

there is


Comparative price



It is worth noting that 1080p monitors and TVs can, with necessary, work in 1080i mode. So if your provider digital television uses an outdated standard interlaced, you can safely take the device with support for a more modern standard. Switching from “i” to “p” – for example, when using a media player or game console – You will feel the improvement in image quality.
