720p HDħ20p HD is the “original” HD standard, but it was fairly promptly overcome by 1080p. If you want the best image quality, the highest resolution you can get is your best bet. Things like color reproduction and aliasing improve as a resolution heightens, too. The higher the resolution, the sharper your image will be.
A similar standard called DCI 4K also has a width of 4096 pixels, which is where the “4” comes from in that context. (Many still call it that, since it’s accurate and follows the standard.) The reason 4K has taken off as a name for the resolution is that you can fit exactly four 1920 x 1080 images inside its single 3840 x 2160 image. So 720p is actually a 1280 x 720 resolution, while 1080p is 1920 x 1080, and so on.ĤK is a bit different- if it still followed the height rule, it would be called 2160p. In the context of 720p and so on, the number refers to the pixel height of the image in a 16:9 aspect ratio. Resolution is the measure of pixels in an image. Understanding Resolutionsįirst and foremost, let’s explain what resolution even is. These are the four most popular resolutions on the market, and we’re going to help explain the differences between them to the best of our ability. Today, we’re going to pit 720p vs 1080p vs 1440p vs 4K against each other.
