The favored aspect ratio of mass-market display industry products has changed gradually from 4:3, then to 16:10, then to 16:9, and has now changed to 18:9 for smartphones. [65] [ needs update] The 4:3 aspect ratio generally reflects older products, especially the era of the cathode ray tube (CRT). The 16:10 aspect ratio had its largest use in the 1995–2010 period, and the 16:9 aspect ratio tends to reflect post-2010 mass-market computer monitor, laptop, and entertainment products displays. On CRTs, there was often a difference between the aspect ratio of the computer resolution and the aspect ratio of the display causing non-square pixels (e.g. 320 × 200 or 1280 × 1024 on a 4:3 display). Super Video Graphics Array, abbreviated to Super VGA or SVGA, [7] [31] also known as Ultra Video Graphics Array, [153] abbreviated to Ultra VGA or UVGA, is a broad term that covers a wide range of computer display standards. [154] XGA+ stands for Extended Graphics Array Plus and is a computer display standard, usually understood to refer to the 1152 × 864 resolution with an aspect ratio of 4:3. Until the advent of widescreen LCDs, XGA+ was often used on 17-inch desktop CRT monitors. [30] It is the highest 4:3 resolution not greater than 2 20 pixels (≈1.05 megapixels), with its horizontal dimension a multiple of 32 pixels. This enables it to fit closely into a video memory or framebuffer of 1 MB (1 × 2 20 bytes), assuming the use of one byte per pixel. The common multiple of 32 pixels constraint is related to alignment.a b c d e f "NVIDIA Tegra FAQ" (PDF) (FAQ). Nvidia . Retrieved 2013-05-22.

Three-dimensional computer graphics common on television throughout the 1980s were mostly rendered at this resolution, causing objects to have jagged edges on the top and bottom when edges were not anti-aliased. Our company ethos is to supply quality products and innovative solutions ensuring we offer an exceptional customer experience at a fair price.

WQVGA has also been used to describe displays that are not 240 pixels high, for example, Sixteenth HD1080 displays which are 480 pixels wide and 270 or 272 pixels high. This may be due to WQVGA having the nearest screen height. Since a pixel must be a whole number, rounding up to 854 ensures inclusion of the entire image. 853 × 480 is the 16:9 equivalent for NTSC (480 lines) on a display with square pixels. Citations are needed that displays with this resolution exist. Sony manufactured a 17-inch CRT monitor with a 5:4 aspect ratio designed for this resolution. It was sold under the Apple brand name.

The LG Gram 17 introduced in 2019 [175] uses a 17-inch WQXGA display. It has been updated with the LG Gram 2021 [176] that retains the same screen size and resolution. Since QVGA is 320 pixels wide and 240 pixels high (aspect ratio of 4:3), the resolution of a WQVGA screen might be 360 × 240 (3:2 aspect ratio), 384 × 240 (16:10 aspect ratio), 400 × 240 (5:3 – such as the Nintendo 3DS screen), 426 × 240, 428 × 240 (≈16:9 ratio) or 432 × 240 (18:10 aspect ratio). As with WVGA, exact ratios of n:9 are difficult because of the way VGA controllers internally deal with pixels. For instance, when using graphical combinatorial operations on pixels, VGA controllers will use 1 bit per pixel. Since bits cannot be accessed individually but by chunks of 16 or an even higher power of 2, this limits the horizontal resolution to a 16-pixel granularity, i.e., the horizontal resolution must be divisible by 16. In the case of the 16:9 ratio, with 240 pixels high, the horizontal resolution should be 240 / 9 × 16 = 426. 6 (426 2⁄ 3), the closest multiple of 16 is 432.

This resolution, sometimes referred to as 4K UHD or 4K × 2K, has a 16:9 aspect ratio and 8,294,400 pixels. It is double the size of Full HD ( 1920 × 1080) in both dimensions for a total of four times as many pixels, and triple the size of HD ( 1280 × 720) in both dimensions for a total of nine times as many pixels. It is the lowest common multiple of the HDTV resolutions. The next bigger resolution in vertical direction is UHD+ (WQUXGA) 3840 × 2400 with an apect ratio of 16∶10. Malik, Haroon (9 January 2008).

About This Article

Originally, it was an extension to the VGA standard first released by IBM in 1987. Unlike VGA – a purely IBM-defined standard – Super VGA was defined by the Video Electronics Standards Association (VESA), an open consortium set up to promote interoperability and define standards. When used as a resolution specification, in contrast to VGA or XGA for example, the term SVGA normally refers to a resolution of 800 × 600 pixels. The marginally higher resolution 832 × 624 is the highest 4:3 resolution not greater than 2 19 pixels, with its horizontal dimension a multiple of 32 pixels. This enables it to fit within a framebuffer of 512 KB (512 × 2 10 bytes), and the common multiple of 32 pixels constraint is related to alignment. For these reasons, this resolution was available on the Macintosh LC III and other systems. [ citation needed] 1024 × 576, 1024 × 600 (WSVGA) [ edit ]
