The resolution of a television or a PC monitor is an important indication of how the image content is displayed. According to its definition, it is the measure of the image size made up of grids and pixels and can also be high-resolution in the Ultra HD and 4K formats. The higher the resolution, the sharper and more detailed moving images are when viewed.
In display technology, the image resolution is an important factor for the quality of the image content. It determines the number of pixels that make up an image. This concerns the number of pixels arranged in a line and which is multiplied by the number of lines of the screen. The two values result in the image or video resolution.
The more pixels there are and the greater the image resolution, the more details are visible on monitors. The larger the screen can be without a loss of quality in the display. The number of total pixels per side length always counts for the screen resolution.
Standard resolutions specify precisely which formats can be displayed and how good the image quality is on a larger screen. In addition to small VGA and SVGA resolutions of 640 x 480 and 800 x 600 pixels, HD Ready with 1280 x 720, Full HD with 1920 x 1080, Ultra HD or 4K with 3840 x 2160 and Full UHD 8K are common 7680×4320 pixels.
High-definition televisions and screens are in vogue. A high screen resolution is only advantageous for larger formats and monitors and determines the image quality and sharpness. The digital resolution determines how detailed content is displayed. A high resolution is better so that the square pixels are not visible in a very large image format and deteriorate the image.
The number of pixels in itself says little at first. Only a comparison in connection with the format and aspect ratio allows you to understand what the grid looks like and how fine or coarse the display of the image content is. Another crucial piece of information is the real size of the screen area.
Each monitor has a certain size, which can be specified in length and width, but also as the screen diagonal. The latter is given either in centimeters or in inches. When evaluating the screen, the diagonal and the maximum resolution are particularly interesting. Both values determine the image quality and are coordinated with each other.
The larger the television, the higher the maximum resolution must be. Such information is decisive for the aspect ratio of films. 16:9 is common for televisions, with a black bar appearing at the top and bottom of the screen or a large picture is cropped on the left and right. This aspect ratio is typical of Full HD and Ultra HD pixel resolution, while 4K requires an aspect ratio of 17:9.
