DIRECTV, DISH, and Xfinity offer 4k content. Amazon Prime Video, Netflix, Disney +, Vudu, and Youtube now offer 4k videos. 8 million pixels, 4 times the amount as a 1080p screen, makes for a better image. If you currently have a 1080p screen and are thinking about making a move to a 4k screen, here are five reasons to switch: Why You Should Ultimately Switch to a 4k Screen This is referred to as 4:2:0.Īs 4k has four times the amount of pixels as 1080p, not only will there be four times more Y or luma values, but there will be four times more Cb and Cr values, making for a clearer, sharper, and more vivid image. 75% of the Cb and Cr values are, therefore, discarded. However, to save data, and since our eyes are more sensitive to brightness than color, as long as the Y, the luma value is kept intact, the Cb and Cr values can be shared with their three neighboring pixels. If each pixel had its own Y, Cb, and Cr value, it would be referred to as 4:4:4. It tells us how bright the pixel should be. Ideally, each and every pixel should have its own Y, Cb, and Cr value. Chroma subsampling is the process of compressing data. Well, this can be explained with something called chroma subsampling. When you watch a 1080p video and a 4k video on a 1080p screen, you’ll notice that the 4k video is much clearer and has a far greater contrast ratio. Why Does 4k Video Look Better on a 1080p Screen? 4k also offers a better contrast ratio than 1080p, meaning that there is a larger difference between the brightest color, white, and the darkest color, black. The main difference between the two, in the most non-technical sense, is that 4k offers a sharper image than 1080p. The picture aspect ratio for 4k is usually about 16:9, the same as 1080p.Ĥk offers a resolution of 8 million megapixels. It is also known as “Ultra High Definition.” It consists of 3840 pixels horizontally and 2160 pixels vertically. Sometimes referred to as 2k, 1080p offers a resolution of 2.1 million megapixels.Ĥk emerged as an option in 2012. Progressive scan is the way that an image is projected onto the screen in sequential order from top to bottom. The “p” in 1080p stands for progressive scan, not pixels, as sometimes thought.
The picture aspect ratio for 1080p is usually 16:9, meaning the image has a width of 16 units and a height of 9 units.
It is also known as “full HD, or full high definition.” It consists of 1920 pixels horizontally and 1080 pixels vertically. It is the next step up after 720p resolution screens. Before we continue, let’s make sure the difference between 1080p and 4k is known.ġ080p first appeared in 2007.
