In the charts above, the naming convention is made pretty clear, though it's not without its inconsistencies. For example, every 6:5 format has a far lower horizontal pixel count than its name suggests since these formats are intended to be used with anamorphic lenses, and the images will have a wider horizontal pixel count once they are de-squeezed. There are other minor oddities like 5568×3160 being classified as 6K while 5632×2948 is classified as 5.5K, but this is somewhat expected since this naming convention does not have any "official" set of rules for determining names, it's all just convention-based. In any case, despite the occasional deviation, the main pattern of the naming convention quite clearly follows the horizontal pixel count, and definitely not "how many times 1080p".

The Huion Kamvas Pro 16 (2.5K)—and, by extension, its 13-inch sibling—is essentially a combination of the best features from these three displays, making it (in my humble opinion) the best option for price-conscious creators. You really love putting things in categories, don't you. You can analyze and simplify colloquialisms all you want, but how dare you put two types of people even close to a comparison? For example, the 5K resolution featured in the Retina 5K iMac, 5120×2880, is equivalent to four 2560×1440 screens. If 1440p is "2K" because it’s twice as many pixels as 1080p, then wouldn’t four of them together be called "8K"? (Well, technically 7K since like I said 1440p is 1.77 times not 2 times 1080p, but that’s beside the point). We don’t call it 7K or 8K. We call it 5K, because it's around 5,000 pixels horizontally. It has nothing to do with "how many times 1080p" the resolution is. This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g. red indicates a 4:3 ratio).The QHD also has an aspect ratio of 16:9 which is considered wide and hence some manufacturers choose to put the “W” in front of it to indicate it is WIDE, making it the “WQHD”. 2160p / UHD I was eager to know: did Huion make the same sort of compromises with these new Kamvas Pro displays? As you may have guessed, the answer is a resounding “no.” The Quantum Dot display in the new Kamvas Pro 16 (2.5K) covers over 95% of both the AdobeRGB (right) and DCI-P3 (left) color gamuts. The below image should give you an idea of how big the difference is between various display types.

is not "the definition" of 4K, it is just one of several standardized 4K resolutions, just as we have several standardized 16:9 resolutions but none of them are "the definition" of 16:9, because 16:9 isn't a resolution, it's a category (in this case, anything with a width-to-height ratio of 16:9 fits in that category). And in both cases, it's not really about what resolutions are established by standards. If you have a resolution with a ratio of 16:9, then it's a 16:9 resolution, it doesn't have to have a standards document to go with it, and the same applies to 4K; any resolution with ≈4,000 horizontal pixels is a 4K resolution, because that's the definition of 4K.qHD, often confused with QHD, is actually 1/4th of the HD resolutions. By today’s standards, even an HD resolution is considered as very bad. It has 4 times lesser pixels than a 1080p display resolution. The typical qHD resolution is 960 x 540 pixels. It is also called as 540p. 720p / HD

First things first: when you unbox the Kamvas Pro 16 (2.5K) you’ll find a little adventure in three layers. Below, you will find a detailed aspect ratio and resolution guide. Among other things, you can use it to help identify which resolution to use in post-production when setting up a new project or timeline. Stretching after running, however, is recommended for all runners as not only does it help release muscle tension but it also aids recovery by increasing blood flow. If you’re not sure where to start, have a look at our beginner's guide to post-run stretching. Should you cross-train? Couch to 5K works because it starts with a mix of running and walking to gradually build up your fitness and stamina.However, the term 2K itself is generic, was not coined by DCI, and does not refer specifically to the DCI 2K standard. Usage of the term 2K predates the publication of the DCI standard. [7] [8] [9] ultrawide version of 3840×2160) is listed as "5K 2.4:1". Calling it "4K ultrawide" is improper usage of the term 4K, as it is a 5K resolution, not 4K. a b "Digital Cinema System Specification" (PDF). Digital Cinema Initiatives. 10 October 2012.

So although 2560×1440 is around twice as many pixels as 1080p, it is not called "2K", because that isn’t where these names come from. Since 2560×1440 is approximately 2,500 pixels horizontally, it falls into the 2.5K classification.

This system of shorthands isn’t strictly defined by any industry body, and so there are no absolute rules. But the general consensus is that at the higher values (above 5K, usually) more "plus or minus" margin is given and we round to the nearest whole number instead of 0.5 value. At lower resolutions, it doesn't take as many pixels for two resolutions to be significantly different, so more granularity is needed to distinguish them, so we round to the nearest 0.5. There is no "definition" of where the absolute cutoff point is though. resolution is a generic term for display devices or content having a horizontal resolution of approximately 2,000 pixels. [1] In the movie projection industry, Digital Cinema Initiatives is the dominant standard for 2K output and defines a 2K format with a resolution of 2048 × 1080. [2] [3] For television and consumer media, 1920 × 1080 is the most common 2K resolution, but this is normally referred to as 1080p.
