So if you have a video signal of 1080p, then the video will completely occupy the screen and will show it clearly. If you divide 1920 by 1080, you arrive at 16/9. Also, we can see that by only changing the screen’s resolution, we could see the complete image, albeit with a little less clear image.Įxample: A screen with an aspect ratio of 16:9 and having a resolution of 1920px X 1080px supports multiple video signals. The file size of the first one is larger than the second one. In today’s times, most of the content you see on television and online is in the aspect ratio of 16:9.ĭepicted above is a difference between watching a video on a screen having an aspect ratio of 4:3 with a display resolution of 800px X 600px and a screen having the same aspect ratio but a different resolution of 500px X 375px. When you buy a monitor or television set, you will see that there are three important specifications – display aspect ratio, display resolution, and video signal support. We combine large amounts of pixels to form a digital video frame. Screen resolution is a measurement of the total number of pixels and a pixel is the smallest unit of a digital graphic. When you go to buy a monitor or television set, you see the following terms in their specifications: SD (Standard Definition), HD (High Definition), HD Ready, Full HD, 2K, UHD ( Ultra HD)- sometimes referred to as 4K & 8K UHD. The other is one of your screen resolution or display resolution. Also, we can use software applications to alter the video resolutions. A video shot with a high megapixel camera sensor will result in a high-resolution video. The total number of recorded pixels is adjusted with an aspect ratio to achieve a convention of writing a video resolution in the form of width x height. One is your video resolution which depends on the device from which you shot the video. For example, we see mobile and camera devices with specifications of their camera sensor’s total number of recorded pixels or megapixels like 16MP, 48 MP, etc. To make it easier to understand, we can separate the resolution into two categories. The video quality not only depends on the aspect ratio but also on the resolution. What is the relation between Aspect Ratio and Resolution? Therefore, the aspect ratio used while shooting the video and while displaying it on the screen should be the same so that the video encompasses the whole display screen and does not distort the video. This brings us to a significant point: The term video aspect ratio is relevant to the screen that displays the video and the device used to shoot the video. So that, when played on my friend’s new television set, having an aspect ratio of 16:9, would have distorted the video unless the device itself introduced the black borders on each side. The device used to shot the Charlie Chapline movie supported a display aspect ratio of 4:3. Whereas if the height is larger, we would be dealing with a vertical video. When the width is larger, we are dealing with a horizontal video. Therefore, we write the video aspect ratio as follows: width: height. The video aspect ratio is the relation between the width of the video and its height.
