720P vs 1080P : what is the difference?

When we are watching a movie, usually, the website will choose the most suitable sharpness according to our current internet speed. Therefore, we may not notice that there is a gear-like switch in the bottom right corner of the video website that allows us to manually go to select the picture’s sharpness. There are usually 360p, 720p and 1080p resolutions for us to choose from. Do you know what these resolutions mean and what is the difference between 720p vs 1080p? Next we will answer one by one.

Movie site 360P, 720P, 1080P what they mean?

Let’s take a look at the number in front of the “P”, it is in fact the abbreviation of the English pixel, refers to the width of the monitor (or the number of rows) contains the total number of pixels. Monitors usually consist of a ratio of length*width (vertical*horizontal), but we are accustomed to using the width of the total number of pixels indicated, while ignoring the length of the total number of pixels.

For example, 360P actually means 480 pixel points in length and 360 pixel points in width; 720P means 1280 pixel points in length and 720 pixel points in width; 1080P means 1920 pixel points in length and 1080 pixel points in width. This is often seen with the LED display P3.91, P4.81 is different, LED display figures in front of the “P”, refers to the center distance between the LED lamp beads and lamp beads. For example, P3.91 is actually in the LED display module, the distance between the two LED lamp beads is 3.91mm.

In addition, 720P and 1080P, or HD (High Definition) and FHD (Full High Definition) abbreviation. Some readers may be curious if it is less than 720P definition of the picture, there is no other way to call it? In the display industry, less than 720P clear picture, usually unified called SD (standard definition).

Earlier years, due to the prevalence of 2G network, the size of the cell phone screen at that time is very small, the network speed is very slow, so the standard definition has become the mainstream resolution of the video site, but with the improvement of the world’s network speed and the application of video streaming technology, the current standard definition quality has rarely appeared, is expected to be phased out completely in the near future, so the next step is to focus on the mainstream of the current 720P and 1080P this The difference between the two screen resolution, and listed some clear and easy to understand comparative analysis.

720p vs 1080p: Pixel Points

720P has a total of 921600 pixels, while 1080P has a total of 2073600 pixels. 1080P has 1152000 pixels more than 720P, and the more pixels means that the picture can be made more detailed. Therefore, when we are playing games or watching videos, we tend to see more details when we choose 1080p, while the details of 720p images are usually blurred.

720P VS 1080P: Aspect Ratio

The length*width of 720P pixels is: 1280×720=921600

The length*width of 1080P pixels is: 1920×1080=2073600

If we look carefully at the comparison, we will find that 720P and 1080P both happen to be 16:9 aspect ratio. As for the reason, we have been in: “16:9 aspect ratio: why is it widely used? ” article made a detailed introduction, interested readers can review.

720P vs 1080P: Image Resolution

Since the two contain different pixel points, the resolutions of the two are also completely different. Especially when we enlarge 720p video and 1080p video twice in Adobe Premiere, we will find that 1080p video is clearer and smoother than 720p video.

720P vs 1080P: Compatibility

As both have been around for a long time, they are now fully compatible with any software, games, and videos. If it’s for games or apps from before 2001, the lower resolution has better compatibility. Larger resolutions may make fonts unreadable in some older games or software.

720P vs 1080P: Costs

Usually, the higher the resolution of a monitor, the more it costs. However, current monitors basically include both 720p and 1080p resolutions, so there is no difference between the two, and 1080p is a very affordable option compared to 2K monitors. In the case of a 2K resolution monitor and a 4K resolution monitor, the price of the 4K monitor is usually higher than the 2K monitor.

720P vs 1080P: Refresh Rate

The universal refresh rate for monitors is 60hz, which is suitable for 720p and 1080p. However, as technology has been upgraded, there are now 120hz and 144hz refresh rates, and these high refresh rates are not suitable for lower resolutions, and they can only be applied to monitors with Full HD and above. If you are still using an older monitor, then it is recommended that you replace it as soon as possible to experience an extraordinary smooth feeling.

720p vs 1080p: Loading Speed

This is the only advantage that 720p has over 1080p. Suppose there is a 10G Blu-ray movie, in the same 1G broadband, if one is played in 1080P quality and the other in 720P quality, we will find that the loading speed of 720P is 1.8 times faster than that of 1080P, which is obviously very important in some countries and regions where the Internet speed is slower – as it determines whether you will experience lag when watching a video.

Currently, there are many ways to compress video, earlier by the ITU’s H.26x series and ISO’s MPEG series. Currently with the application of AI video technology, it is possible to minimally compress the video with the intelligent algorithms of AI.
