While PPI is the correct term when referencing monitors and other displays, both terms are often used interchangeably. A higher pixel density will mean that there are more pixels packed into every square inch of your screen. Pixel density is a significant factor because it determines the quality of your image in that a higher pixel density will generally give you better-looking images.
That being said, pixel density also depends on screen size. This means that both have 1, horizontal pixels and 1, vertical pixels. Now imagine that one screen is a inch screen, while the other is a inch screen. Now you can see how pixel density comes into play because you will have the same number of pixels spread across a larger screen with the inch monitor. Thus, the smaller monitor will have a more densely packed pixel density, resulting in smoother lines and sharper images.
Well, the answer is yes and no. While, generally speaking, a higher pixel density is better, there is a point of diminishing returns. As pixel density becomes higher and higher, the noticeable benefits of that higher pixel density become lower and lower.
This will eventually lead to a point where the benefits offered by a higher pixel density are undetectable by your eye. In the example above, the inch monitor would have a pixel density of about 88 ppi , while the inch monitor would have a pixel density of about 69 ppi. To take things even further, it is common for smartphones nowadays to have pixel densities ranging from ppi all the way up to over ppi. The problem here is that the exact point where a higher PPI becomes undetectable is a matter of debate.
Some say that the optimal pixel density is somewhere are around ppi, while others say that the pixel density detectable by the eye is closer to ppi. The following list ranks some of the more common monitor resolutions found on the market nowadays from lowest monitor resolution to highest.
About p Resolution: p resolution, or x , is a progressive-style monitor resolution. About p Resolution : p is a progressive resolution containing x pixels. About 4K Resolution : 4K resolution is so-named due to its horizontal pixel count, although for monitors, 4K resolution is equal to a pixel count of x Although the market share for 4K resolution has increased year-over-year since , its adoption has thus far been limited to internet video streaming, video projection, and commercial televisions.
About 8K Resolution : 8K resolution measures at x pixels and is currently the highest monitor resolution currently available. The technology is so new that commercially available 8K UHD televisions and broadcasts are just now becoming available. On the market, 8K is currently being integrated into TVs, computer monitors, and broadcast cameras. In total pixels, p offers over twice that of p, therefore p is sharper and clearer. Other factors aside, although both are considered to be a part of the HD standard, p has been considered the industry standard for monitors for a while now.
With just over 3. However, p is the most popular monitor resolution currently on the market, while p is just beginning to gain a foothold. Although p, or WQHD, has 4 times more pixels than p. Conversely, p has remained within the smartphone industry for over a decade. Not everything comes down to resolution, however. Image smoothness is affected by many other factors, including how big a TV is, how close one sits to it, what DVD player is in use, what a TV's refresh rate is or what its aspect ratio is set to, and even what the frame rate of the video or game content is.
The video below offers a summary of the differences between p and p in terms of picture quality. The FCC defines high-definition HD quality video as p, p, and i, and all modern TVs carry support for at least p resolution, with many supporting p.
Some video content is filmed or trimmed to a smaller vertical resolution than pixels—or it's interlaced, rather than progressively scanned—but it is still considered HD. When watching digital TV, video quality can vary wildly.
Those who want the best picture quality need to change their TV's settings to accommodate changing video feeds. New TVs may attempt to automatically change settings to whatever is most appropriate, but they may fail to do so in some cases.
Regular DVD quality can vary considerably, with some displaying content at a resolution lower than p, such as p. Moreover, there are still DVD players around that only carry support for up to p or i, meaning a viewer cannot get the full experience of any high-definition DVD they insert into the player.
Netflix typically streams at p, but with the release and expansion of what it calls "Super HD," users are able to stream more and more content at p quality with a high-speed internet connection. Apple TV allows users to choose between p and p streaming. Scharon Harding has a special affinity for gaming peripherals especially monitors , laptops and virtual reality.
