Resolution

 

What does Resolution mean?

Resolution is a standard used to describe the sharpness or clarity of an image or picture. It is used as a metric to judge the quality of monitors, printers, digital images, and many other hardware and software technologies.

Resolution is a term used to describe the display capabilities of mobile devices in the mobile industry? To distinguish between high definition and standard definition films, it is popular in the entertainment medium to differentiate the visual quality of films. It is also used to determine the resolution of a screen, monitor, or TV. Resolution is also called screen resolution.

Resolution is a broad term. It can have different meanings when used in different areas of technology. In the computer and media industry, the resolution is primarily to show the resolution and the number of picture elements (pixels or just dots) that can display both length and height through the screen. Resolution refers to how many pixels width and height can produce. This also applies to digital images.

For audio, resolution refers to the bit depth of digital recording or the number of bits of information stored. It is also directly related to the quality of the recording.

For printers, the resolution refers to the point per inch (dpi) of material produced by the printer, which also indicates how small and fine the dots are. The higher the DPI, the clearer the printout.

For computer images, the resolution is usually described in pixels per inch (ppi), which determines how many pixels per inch are displayed in a given image. The higher the resolution, the higher the value of the image and PPI because the number of pixels per inch is higher. If there are too few pixels in the image, the image will look too large and blurry, which will affect the pixelated images. Non-commercial printers usually print images between 200 and 300 ppi, while commercial equipment usually has a higher value up to 600 ppi.

Image resolution is the total number of pixels represented by a digital image in terms of width and height. For example, an image with a resolution of 1920 x 1080 has a total of 2,073,600 pixels - commonly called a "2 megapixel" image.

Resolution often changes the size of the image, but it also reflects the size of the display, monitor, screen, or TV (display resolution) in terms of its physical ability to focus on light. The HD display has a maximum resolution of 1920 x 1080 pixels, half the resolution of a 4K display (3840 x 2160 pixels).

The clarity of the image depends on the size of the monitor and its resolution. A 27 '' monitor with a resolution of 2560 x 1440 pixels will show clearer images than a monitor of the same size but with a maximum resolution of 1920 x 1080 pixels as the PPI is naturally higher. However, the same resolution of 2560 x 1440 pixels can appear blocky or blurred in a large 60 '' TV.

In computers, resolutions are expressed by the number of pixels (individual points of color) on the display monitor, the number of pixels on the horizontal axis, and the number on the vertical axis. The sharpness of the image on the display depends on the resolution and size of the monitor. The same pixel resolution will be more intense on smaller monitors and will gradually decrease sharpness on larger monitors as the same pixels spread over a larger number of inches.

A given computer display system will have a maximum resolution that depends on its physical ability to focus on light (in this case the physical point size - dot pitch - will match the size of the pixel) and usually several lower resolutions. For example, a display system that supports a maximum resolution of 1280 by 1023 pixels can support 1024 with 768, 800 by 600, and 640 by 480 resolutions. Note that on a monitor of a given size, the maximum resolution can offer a sharp image but can be spread over even a small space for better reading.

Display resolution is not measured in dots per inch as it is usually with a printer. However, the combination of resolution and physical monitor size allows you to determine pixels per inch. In short, PC monitors are somewhere between 50 and 100 pixels per inch. For example, a 15-inch VGA (see display mode) monitor has a resolution of 640 pixels with a 12-inch horizontal line, or about 53 pixels per inch. A smaller VGA display will have more pixels per inch.

Resolution refers to the sharpness and clarity of the image. The term is most often used to describe monitors, printers, and bit-mapped graphic images. In the case of dot-matrix and laser printers, the resolution represents the number of dots per inch. For example, a 300-dpi (dots per inch) printer is capable of printing 300 different dots in a 1-inch-long line. This means they can print 90,000 dots per square inch.

For graphics monitors, the screen resolution represents the number of dots (pixels) across the screen. For example, a 640 by 480-pixel screen is capable of displaying 640 distinct points on every 480 lines or about 300,000 pixels. This translates into different DPI measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640 × 480) shows about 50 dots per inch. 

Printers, monitors, scanners, and other I / O devices are often classified as high resolution, medium resolution, or low resolution. The actual resolution of each of these categories is constantly changing as technology improves.

Standard Display Resolution Sizes

The industry-standard way of representing screen resolution is publishing the number of pixels that make up the two sides of the display rectangle.

A number of standards currently exist when it comes to display resolutions:

Name(s)	Resolution in pixels
High Definition (HD)	1280 x 720
Full HD, FHD	1920 x 1080
2K, Quad HD, QHD	2560 x 1440
4K, Ultra HD	3840 x 2160

Resolution does not refer to the physical size of the display, camera sensor, or image. For example, two displays with the same resolution may have different physical dimensions. Hence the importance of other published parameters - pixel density, which is measured in pixels-per-inch (ppi). Smaller displays of the same resolution will have more pixels per inch so the images provided by them should be more precise and detailed (even if the graphics are physically smaller).
