The resolution is also used in portable devices. In September 2012, Samsung announced the Series 9 WQHD laptop with a 13-inch 2560 × 1440 display. [19] In August 2013, LG announced a 5.5-inch QHD smartphone display, which was used in the LG G3. [20] In October 2013 Vivo announced a smartphone with a 2560 × 1440 display. [21]
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
480p is the shorthand name for a family of video display resolutions.The p stands for progressive scan, i.e. non-interlaced.The 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4 ⁄ 3 = 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) [1] pixels for an approximate 16:9 aspect ...
These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed "Cinemascope", "21∶9" etc.), while the standard horizontal resolution, e.g. 1920 pixels, is usually kept.
All machines in the ST series could also use colour or monochrome VGA monitors with a proper cable or physical adapter, and all but the TT could display 640x400 at 71.25 Hz on VGA monitors. 640×400 640 400 256,000 4:3 (or 16:10 with square pixels)
VGA section on the motherboard in IBM PS/55. The color palette random access memory (RAM) and its corresponding digital-to-analog converter (DAC) were integrated into one chip (the RAMDAC) and the cathode-ray tube controller was integrated into a main VGA chip, which eliminated several other chips in previous graphics adapters, so VGA only additionally required external video RAM and timing ...
I don't see you claiming that 1080i is really 1440x1080 because that's the resolution HDV and broadcast HD use with a 1.33 PAR, and saying 480p is 720x480 just because DVDs achieve that resolution with a 1.18 PAR is the exact same thing. Just because the most common implementation is 720x480 with non-square pixels, it doesn't mean 480p is.
High-definition video (HD video) is video of higher resolution and quality than standard-definition.While there is no standardized meaning for high-definition, generally any video image with considerably more than 480 vertical scan lines (North America) or 576 vertical lines (Europe) is considered high-definition.
