Pixels per inch, a measurement of pixel density, depends on the resolution of a document or device. The average PPI is about 72 dots per inch. The input resolution can be measured by pixels per inch (PPI), and a good photograph usually requires 300 DPI.Know More
PPI and DPI can be used in reference to printing images on paper, computer monitor and TV resolutions, as well as digital cameras (which have three dots per pixel) and smartphone screens. The proper amount of PPI will be determined by the size of the image. Pixels per inch also can be interchanged with pixels per centimeter (PPCM), as they are both measurements of pixel density.
The shorthand "480p" refers to a 480-pixel vertical line that is progressively drawn together with other vertical lines. This mode is in contrast to 480i where each odd or even vertical line is drawn/interlaced at the same time. Interlacing requires less bandwidth, but results in a worse image.Full Answer >
The direction a Dish Network satellite dish is pointed (consisting of the azimuth and elevation) depends on the geographic location of the dish. The direction can be south-southwest or south-southeast depending on which set of satellites the dish is accessing.Full Answer >
LED televisions do not inherently have superior resolution to LCD televisions. LED televisions are LCD displays that use light-emitting diodes to illuminate the display. While this lighting system has potential advantages over older methods of lighting LCD displays, the use of LEDs does not directly affect display resolution.Full Answer >
An 80-inch TV is a TV that measures 80 inches diagonally from the lower left-hand corner to the top right-hand corner. This measurement starts on the inside of the bevel, or frame, of the TV.Full Answer >
