We will pit 720p vs 1080p vs 1440p vs 4K against each other today. These are the four most common resolutions on the market, and we are looking to assist clarify to the best of our ability the distinctions between them. First of all, let’s discuss what the resolution is. The measure of pixels in an image is the resolution. The number refers to the pixel height of the image in a 16:9 aspect ratio in the sense of 720p and so on. So, 720p is basically a resolution of 1280 x 720, while 1080p is 1920 x 1080, and so on.
4K is a little different- it would be called 2160p if it still followed the height norm. (Since it’s reliable and meets the norm, many still call it that.) The reason 4K has taken off as a name for the resolution is that within its single 3840 x 2160 image, you can fit exactly four 1920 x 1080 images. A similar standard called DCI 4K also has a width of 4096 pixels, which in that sense, is where the “4” comes from. Yeah, and even ads! The greater the resolution, the better your picture is going to be. Things like color replication and aliasing are improved as the resolution also increases.
720p HD is the “original” HD standard, but 1080p conquered it fairly easily. Even so, in the PS360 and even PS4 / Xbox One generations of consoles, 720p was still used frequently, particularly for demanding games. With greater resolution (such as 1080p and 4K) typically reserved for Blu-ray releases or streaming services, 720p still remains the most popular standard for broadcast HDTV.
1080p FHD (Full HD)
In this setting, 1080p (1920 x 1080) is known as “Full HD” and is what most individuals think of. This provides approximately twice the resolution of 720p, which is what most HDTVs on the market use. Where possible, current-gen consoles strive for this resolution, as do most gaming PCs. Most web video content will also be created at least in this resolution, but before a Blu-ray release, several TV series and such will not be available in this resolution. (1080p is also the standard Blu-ray mo resolution. If you are looking for a comparison of 2 K vs. 4K, it is here—just kind of. Most of them believe they’re talking about 1440p when people refer to “2 K”. They aren’t. They’re a lot closer to 1080p technically, and even then. That’s not exactly right. Simply put, 4K is anything … 2 K is not. Don’t add people to the chaos.
1440p QHD (Quad HD)
1440p (2560 x 1440) is known as “Quad HD.” This is because it quadruples the 720p, but not 1080p, resolution. As a PC-exclusive display resolution, 1440p is usually utilized, even if some of the higher-end consoles also upgrade from 1440p to reach a non-native 4K image. Although 1440p is a considerable improvement in resolution over 1080p, the most popular display size for 1440p is 27 inches.
