Computer display standard

Computer display standards are a combination of aspect ratio, display size, display resolution, color depth, and refresh rate. They are associated with specific expansion cards, video connectors and monitors.

History

 
Front and rear views of the TVM MD-3 CRT monitor (EGA / pre VGA era). Note the DE-9 connector, cryptic mode switch, contrast and brightness controls at front, and the V-Size and V-Hold knobs at rear, which allow the control of the scaling and signal to CRT refresh-rate synchronization respectively.

Various computer display standards or display modes have been used in the history of the personal computer. They are often a combination of aspect ratio (specified as width-to-height ratio), display resolution (specified as the width and height in pixels), color depth (measured in bits per pixel), and refresh rate (expressed in hertz). Associated with the screen resolution and refresh rate is a display adapter. Earlier display adapters were simple frame-buffers, but later display standards also specified a more extensive set of display functions and software controlled interface.

Beyond display modes, the VESA industry organization has defined several standards related to power management and device identification, while ergonomics standards are set by the TCO.

Standards

A number of common resolutions have been used with computers descended from the original IBM PC. Some of these are now supported by other families of personal computers. These are de facto standards, usually originated by one manufacturer and reverse-engineered by others, though the VESA group has co-ordinated the efforts of several leading video display adapter manufacturers. Video standards associated with IBM-PC-descended personal computers are shown in the diagram and table below, alongside those of early Macintosh and other makes for comparison. (From the early 1990s onwards, most manufacturers moved over to PC display standards thanks to widely available and affordable hardware).

Table of computer display standards
Video standard Full name Description Display resolution (pixels) Width (px) Height (px) Area (px) Aspect ratio Color depth (2^bpp colors)
QQVGA Quarter Quarter Video Graphics Array Used on some portable devices, and is a common alternative resolution to QCIF for webcams and other online video streams in low-bandwidth situations, and on video modes of early and later low-end digital cameras. 160×120 (19k) 160 120 19,200 4:3
UNNAMED UNNAMED A common size for LCDs manufactured for small consumer electronics, basic mobile phones and feature phones, typically in a 1.7" to 1.9" diagonal size. This LCD is often used in portrait (128×160) orientation. The unusual 5:4 aspect ratio makes the display slightly different from QQVGA dimensions. 160×128 (20k) 160 128 20,480 5:4
UNNAMED UNNAMED A shared size for older portable video game systems. The nearly-square (but landscape) aspect ratio and coarse pixel resolution gave these games a characteristic visual style. Colour depth ranged from 4 colours (2 bpp) with the original Game Boy, through 16–32 colours (4–5 bpp) with the Atari Lynx and Game Gear, to a maximum of 56 colours (equivalent of 6 bpp) from a wider palette with the Game Boy Color. Also appears as a YouTube resolution option ("144p"). 160×144 (23k) 160 144 23,040 10:9 2 bpp (6 bpp effective)
HQVGA Half Quarter Video Graphics Array Used with some smaller, cheaper portable devices, including lower-end cellphones and PDAs, and perhaps most commonly in the Nintendo Game Boy Advance (with, in that guise, 32k colours (15 bpp) on-screen). 240×160 (38k) 240 160 38,400 3:2
QVGA Quarter Video Graphics Array Half the resolution in each dimension as standard VGA. First appeared as a VESA mode (134h=256 color, 135h=Hi-Color) that primarily allowed 80x30 character text with graphics, and should not be confused with CGA (320x200); QVGA is normally used when describing screens on portable devices (PDAs, pocket media players, feature phones, smartphones, etc.). No set colour depth or refresh rate is associated with this standard or those that follow, as it is dependent both on the manufacturing quality of the screen and the capabilities of the attached display driver hardware, and almost always incorporates an LCD panel with no visible line-scanning. However, it would typically be in the 8-to-12 bpp (256–4096 colours) through 18 bpp (262,144 colours) range. 320×240 (77k) 320 240 76,800 4:3
WQVGA Wide Quarter Video Graphics Array Effectively 1/16 the total resolution (1/4 in each dimension) of "Full HD", but with the height aligned to an 8-pixel "macroblock" boundary. Common in small-screen video applications, including portable DVD players and the Sony PSP. 480×272 (131k) 480 272 130,560 ~1% narrower than 16:9
TV Computer Non-interlaced TV-as-monitor Various Apple, Atari, Commodore, Sinclair, Acorn, Tandy and other home and small-office computers introduced from 1977 through to the mid-1980s. They used televisions for display output and had a typical usable screen resolution from 102–320 pixels wide and usually 192–256 lines high, in non-interlaced (NI) mode for a more stable image (displaying a full image on each 1/50th / 1/60th-second field, instead of splitting it across each frame). The limited resolution led to displays with a characteristic wide overscan border around the active area. Some more powerful machines were able to display higher horizontal resolutions—either in text-mode alone or in low-colour bitmap graphics, and typically by halving the width of each pixel, rather than physically expanding the display area—but were still confined in the vertical dimension by the relatively slow horizontal scanning rate of a domestic TV set. These same standards—albeit with progressively greater colour depth and upstream graphical processing ability—would see extended use and popularity in TV-connected game consoles right through to the end of the 20th century. 140×192 NI (low-end), 320×200 NI (typical), 640×256 NI (high-end) 4:3 (non-square pixels) 1–4 bpp typical, 2 or 3 bpp common.
ST Low/Med Resolution Atari ST (etc.) Colour, Broadcast-standard Atari ST line. Colour modes using NTSC or PAL-compliant televisions, and monochrome, composite video or RGB-component monitors. 640×200, 320×200 4:3 (or 16:10 with square pixels) 2–4 bpp for ST, 2–15 bpp on the Falcon.
ST High Resolution Atari ST (etc.) Monochrome, proprietary standard Atari ST line. High resolution monochrome mode using a custom non-interlaced monitor with the slightly lower vertical resolution (in order to be an integer multiple of low and medium resolution and thus utilize the same amount of RAM for the framebuffer) allowing a "flicker free" 71.25 Hz refresh rate, higher even than the highest refresh rate provided by VGA. 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. 640×400 256,000 4:3 (or 16:10 with square pixels) 1 bpp for ST, on the Falcon: 1-8 bpp grayscale on the ST monochrome monitor, and 8 bpp colour on VGA/multisync monitors.
TT High Resolution Atari TT (etc.) Monochrome, proprietary standard Atari TT line. High resolution monochrome mode using a custom non-interlaced ECL monitor, allowing a higher, "flicker free" 70 Hz refresh rate. 1280×960 (1229k) 1,228,800 4:3 (or 16:10 with square pixels) 1 bpp for TT.
Video monitor I/NI Full-broadcast resolution video monitor or television Commodore Amiga line and others, e.g. Acorn Archimedes, Atari Falcon). They used NTSC or PAL-compliant televisions and monochrome, composite video or RGB-component monitors. The interlaced (i or I) mode produced visible flickering of finer details, eventually fixable by use of scan doubler devices and VGA monitors. 720×480i/576i maximum. Typically 640×400i/512i or 640×200/256 NI, and 320×200/256 NI for games. 4:3 (non-square pixels) Up to 6 bpp for Amiga (8 bpp with later models), typically 2–4 bpp for most hi-res applications (saving memory and processing time), 4–5 bpp for games and "fake" 12/18 bpp for static images (HAM mode). Up to 15 bpp for Archimedes and Falcon (12 bpp for TT), but typically 4 bpp in use.
Mac Mono 9" Original Apple Macintosh display The single fixed-screen mode used in first-generation (128k and 512k) Apple Mac computers, launched in 1984, with a monochrome 9" CRT integrated into the body of the computer. Used to display one of the first mass-market full-time GUIs, and one of the earliest non-interlaced default displays with more than 256 lines of vertical resolution. (Early models used a 384×256 screen; both standards are cut down from the 720×364 of the preceding Lisa model) 512×342 (175k) 175,104 Very nearly 3:2 (to within 0.2%); 256:171 exact. Displayed with square pixels on a moderately wide-screen monitor (equivalent to 16:10.67 in modern terms). bpp
Mac Colour Apple Mac II and later models The second-generation Macintosh, launched in 1987, came with colour (and greyscale) capability as standard, at two levels, depending on monitor size—512×384 (1/4 of the later XGA standard) on a 12" (4:3) colour or greyscale (monochrome) monitor; 640×480 with a larger (13" or 14") high-resolution monitor (superficially similar to VGA, but at a higher 67 Hz refresh rate)—with 8-bit colour/256 grey shades at the lower resolution, and either 4-bit or 8-bit colour (16/256 grey) in high resolution depending on installed memory (256 or 512 kB), all out of a full 24-bit master palette. The result was equivalent to VGA or even PGC—but with a wide palette—at a point simultaneous with the IBM launch of VGA.

Later, larger monitors (15" and 16") allowed use of an SVGA-like binary-half-megapixel 832×624 resolution (at 75 Hz) that was eventually used as the default setting for the original, late-1990s iMac. Even larger 17" and 19" monitors could attain higher resolutions still, when connected to a suitably capable computer, but apart from the 1152×870 "XGA+" mode discussed further below, Mac resolutions beyond 832×624 tended to fall into line with PC standards, using what were essentially rebadged PC monitors with a different cable connection. Mac models after the II (Power Mac, Quadra, etc.) also allowed at first 16-bit High Colour (65,536, or "Thousands of" colours), and then 24-bit True Colour (16.7M, or "Millions of" colours), but much like PC standards beyond XGA, the increase in colour depth past 8 bpp was not strictly tied to changing resolution standards.

512×384 (197k), 640×480 (307k), 832×624 (519k) 4:3 bpp, 8 bpp, and later 16/24 bpp
PowerBook internal panel PowerBook, early generations The first PowerBook, released in 1991, replaced the original Mac Portable (basically an original Mac with an LCD, keyboard and trackball in a lunchbox-style shell), and introduced a new 640×400 greyscale screen. This was joined in 1993 with the PowerBook 165c, which kept the same resolution but added colour capability similar to that of Mac II (256 colours from a palette of 16.7 million). 640×400 (256k) 256,000 16:10 / 8:5 (square pixels) 8 bpp
MDA Monochrome Display Adapter The original standard on IBM PCs and IBM PC XTs with 4 kB video RAM. Introduced in 1981 by IBM. Supports text mode only.[1] 720×350 (252k) 252,000 72:35 (effectively 4:3 (non-square pixels) on CRTs but could be a variety of aspects on LCDs) bpp

Hercules A monochrome display capable of sharp text and graphics for its time. Very popular with the Lotus 1-2-3 spreadsheet application, which was one of PC's first killer apps. Introduced in 1982. 720×348 (251k) 250,560 60:29 (effectively 4:3) 1 bpp
Orchid Graphics Adapter A monochrome display that expanded Monochrome Display Adapter's capabilities with graphics. Introduced in 1982. 720×350 252,000 60:29 (effectively 4:3) 1 bpp
EGA Enhanced Graphics Adapter Introduced in 1984 by IBM. A resolution of 640×350 pixels of 16 different colours in 4 bits per pixel (bpp), selectable from a 64-colour palette in 2 bits per each of red-green-blue (RGB) unit.[1] Other commonly used modes were the existing CGA 320×200 and 640×200 resolutions in 4 bpp, with a fixed palette corresponding to the 16 colours available in CGA text mode, allowing an EGA card to be used in full colour with an unmodified CGA monitor by setting the correct DIP switch options; plus full EGA resolution (and CGA hi-res) in monochrome, if installed memory was insufficient for full colour at above 320×200. 640×350 (224k), 640×200 (128k), 320×200 (64k) 64:35, 16:5 and 16:10/8:5 (all effectively 4:3) 4 bpp
Professional Graphics Controller With on-board 2D and 3D acceleration introduced in 1984 for the 8-bit PC-bus, intended for CAD applications, a triple-board display adapter with built-in processor, and displaying high-resolution, full-colour graphics at a 60 Hz frame rate.[1] 640×480 (307k) 307,200 4:3 8 bpp
MCGA Multi-Color Graphics Array Introduced by IBM on ISA-based PS/2 models in 1987, with reduced cost compared to VGA. MCGA had a 320×200 256-colour (from a 262,144 colour palette) mode, and a 640×480 mode only in monochrome due to 64k video memory, compared to the 256k memory of VGA.[1] 320×200 (64k)

VGA Video Graphics Array Introduced on MCA-based PS/2 models in 1987, it replaced the digital TTL signaling of EGA and earlier standards with analog RGBHV signaling, using the synonymous VGA connector. As with EGA, the VGA standard actually encompasses a set of different resolutions; 640×480 is sometimes referred to as "VGA resolution" today, however as per the original standard this mode actually only supports 16 colours (4 bpp) at 60 Hz. Other common display modes also defined as VGA include 320×200 at 256 colours (8 bpp) (standard VGA resolution for DOS games that stems from halving the pixel rate of 640×400, but doubling color depth) and a text mode with 720×400 pixels; these modes run at 70 Hz and use non-square pixels, so 4:3 aspect correction is required for correct display.

Furthermore, VGA displays and adapters are generally capable of Mode X graphics, an undocumented mode to allow increased non-standard resolutions, most commonly 320×240 (with 8 bpp and square pixels) at 60 Hz.[1] VGA, like the majority of the following standards, was capable of displaying most standard modes featured by IBM-compatible PCs—CGA, EGA, MDA and MCGA—but typically not Hercules or PGA/PGC.

8514 Precursor to XGA and released shortly after VGA in 1987. 8514/A cards displayed interlaced video at 43.5 Hz in a 1024×768 resolution, and at 640×480, 60 Hz non-interlaced, both with up to 256 colours.[1]

The high-resolution mode introduced by 8514/A became a de facto general standard in a succession of computing and digital-media fields for more than two decades, arguably more so than SVGA, with successive IBM and clone videocards and CRT monitors (a multisync monitor's grade being broadly determinable by whether it could display 1024×768 at all, or show it interlaced, non-interlaced, or "flicker-free"), LCD panels (the standard resolution for 14" and 15" 4:3 desktop monitors, and a whole generation of 11–15" laptops), early plasma and HD ready LCD televisions (albeit at a stretched 16:9 aspect ratio, showing down-scaled material), professional video projectors, and most recently, tablet computers.

SVGA Super Video Graphics Array An extension to VGA defined by VESA for IBM PC-compatible computers in 1989 meant to take advantage of video cards that exceeded the minimum 256 kB defined in the VGA standard. For instance, one of the early supported modes was 800×600 in 16 colours at a slightly lower 56 Hz refresh rate, leading to 800×600 sometimes being referred to as "SVGA resolution" today.

Over the course of the early-to-mid-1990s, "SVGA" became a quasi-standard term in PC games, typically referring to a 640×480 resolution using 256 colours (8 bpp) at 60 Hz refresh rate. Many other higher and lower modes were standardized in the VESA BIOS Extensions, leading to the establishment of "SVGA" and "VESA" as catch-all terms encompassing output modes that surpassed the original VGA specifications.

XGA Extended Graphics Array An IBM display standard introduced in 1990. XGA built on 8514/A's existing 1024×768 mode and added support for "high colour" (65,536 colours, 16 bpp) at 640×480. The second revision ("XGA-2") was a more thorough upgrade, offering higher refresh rates (75 Hz and up, non-interlaced, up to at least 1024×768), improved performance, and a fully programmable display engine capable of almost any resolution within its physical limits. For example, 1280×1024 (5:4) or 1360×1024 (4:3) in 16 colours at 60 Hz, 1056×400 [14h] Text Mode (132×50 characters); 800×600 in 256 or 64k colours; and even as high as 1600×1200 (at a reduced 50 Hz scan rate) with a high-quality multisync monitor (or an otherwise non-standard 960×720 at 60 Hz on a lower-end one capable of high refresh rates at 800×600, but only interlaced mode at 1024×768).[1] However, the extended modes required custom drivers, and so only the basic options (1024×768×8 I, 640×480×16 NI, high-res text) were commonly used outside Windows and other hardware-abstracting graphical environments. 1024×768 (786k)

XGA+ Extended Graphics Array Plus Although not an official name, this term is now used to refer to 1152×864, which is the largest 4:3 array yielding less than a binary megapixel (2^20, 1048576 pixels, 1048 decimal kilopixels), thus allowing the greatest "normal" resolution at common colour depths with a standard amount of video memory (128 kB, 512 kB, 1 MB, 2 MB, etc.). Variants of this were used by Apple Computer (at 1152×870) and Sun Microsystems (at 1152×900) for 21" CRT displays. 1152×864 (995k)

SXGA Super Extended Graphics Array A widely used de facto standard, introduced with XGA-2 and other early "multiscan" graphics cards and monitors, with an unusual aspect ratio of 5:4 (1.25:1) instead of the more common 4:3 (1.33:1), meaning that even 4:3 pictures and video will appear letterboxed on the narrower 5:4 screens. This is generally the native resolution—with, therefore, square pixels—of standard 17" and 19" LCD monitors. It was often a recommended resolution for 17" and 19" CRTs also, though as they were usually produced in a 4:3 aspect ratio, it either gave non-square pixels or required adjustment to show small vertical borders at each side of the image. Allows 24-bit colour in 4 MB of graphics memory, or 4-bit colour in 640 kB.
  • Some manufacturers,[who?] noting that the de facto industry standard was VGA (Video Graphics Array), termed this the Extended Video Graphics Array, or XVGA.

Display resolution prefixes

Although the common standard prefixes super and ultra do not indicate specific modifiers to base standard resolutions, several others do:

Quarter (Q or q)
A quarter of the base resolution. E.g. QVGA, a term for a 320×240 resolution, half the width and height of VGA, hence the quarter total resolution. The "Q" prefix usually indicates "Quad" (4 times as many, not 1/4 times as many) in higher resolutions, and sometimes "q" is used instead of "Q" to specify quarter (by analogy with SI prefixes m/M[citation needed]), but this usage is not consistent.[3]
Wide (W)
The base resolution increased by increasing the width and keeping the height constant, for square or near-square pixels on a widescreen display, usually with an aspect ratio of either 16:9 (adding an extra 1/3rd width vs a standard 4:3 display) or 16:10 (adding an extra 1/5th). However, it is sometimes used to denote a resolution that would have roughly the same total pixel count as this, but in a different aspect and sharing neither the horizontal OR vertical resolution—typically for a 16:10 resolution which is narrower but taller than the 16:9 option, and therefore larger in both dimensions than the base standard (e.g., compare 1366×768 and 1280×800, both commonly labelled as "WXGA", vs the base 1024×768 "XGA").
Quad(ruple) (Q)
Four times as many pixels compared to the base resolution, i.e. twice the horizontal and vertical resolution respectively.
Hex(adecatuple) (H)
Sixteen times as many pixels compared to the base resolution, i.e. four times the horizontal and vertical resolutions respectively.
Super (S), eXtended (X), Plus (+) and/or Ultra (U)
Vaguer terms denoting successive incremental steps up the resolution ladder from some comparative, more established base, usually somewhat less severe a jump than quartering or Quadrupling—typically less than doubling, and sometimes not even as much of a change as making a "wide" version; for example SVGA (800×600 vs 640×480), SXGA (1280×1024 vs 1024×768), SXGA+ (1400×1050 vs 1280×1024) and UXGA (1600×1200 vs 1024×768 - or more fittingly, vs the 1280×1024 of SXGA, the conceptual "next step down" at the time of UXGA's inception, or the 1400×1050 of SXGA+). Given the use of "X" in "XGA", it is not often used as an additional modifier (e.g. there is no such thing as XVGA except as an alternative designation for SXGA) unless its meaning would be unambiguous.

These prefixes are also often combined, as in WQXGA or WHUXGA, with levels of stacking not hindered by the same consideration towards readability as the decline of the added "X" - especially as there is not even a defined hierarchy or value for S/X/U/+ modifiers.

specified a more extensive set of display functions and software controlled interface Beyond display modes the VESA industry organization has defined several standards related to power management and device identification while ergonomics standards are set by the TCO Standards EditA number of common resolutions have been used with computers descended from the original IBM PC Some of these are now supported by other families of personal computers These are de facto standards usually originated by one manufacturer and reverse engineered by others though the VESA group has co ordinated the efforts of several leading video display adapter manufacturers Video standards associated with IBM PC descended personal computers are shown in the diagram and table below alongside those of early

Computer Non interlaced TV as monitor Various Apple Atari Commodore Sinclair Acorn Tandy and other home and small office computers introduced from 1977 through to the mid 1980s They used televisions

1 50th 1 60th second field instead of splitting it across each frame The limited resolution led to displays with a characteristic wide overscan border around the active area Some more powerful machines were able to display higher horizontal resolutions either in text mode alone or in low colour bitmap graphics and typically by halving the width of each pixel rather than physically expanding the display area but were still confined in the vertical dimension by the relatively slow horizontal scanning rate of a domestic TV set These same standards albeit with progressively greater colour depth and upstream graphical processing ability would see extended use and popularity in TV connected game consoles right through to the end of the 20th century 140 192 NI low end 320 200 NI typical

bppDisplay resolution prefixes EditAlthough the common standard prefixes super and ultra do not indicate specific modifiers to base standard resolutions several others do Quarter Q or q A quarter of the base resolution E g QVGA a term for a 320 240 resolution half the width and height of VGA hence the quarter total resolution The Q prefix usually indicates Quad 4 times as many not 1 4 times as many in higher resolutions and sometimes q is used instead of Q to specify quarter by analogy with SI prefixes m M citation needed but this usage is not consistent 3 Wide W The base resolution increased by increasing the width and keeping the height constant for square or near square pixels on a widescreen display usually with an aspect ratio of either 16 9 adding an extra 1 3rd width vs a standard 4 3 display or 16 10 adding an extra 1 5th However it is sometimes used to denote a resolution that would have roughly the same total pixel count as this but in a different aspect and sharing neither the horizontal OR vertical resolution typically for a 16 10 resolution which is narrower but taller than the 16 9 option and therefore larger in both dimensions than the base standard e g compare 1366 768 and 1280 800 both commonly labelled as WXGA vs the base 1024 768 XGA Quad ruple Q Four times as many pixels compared to the base resolution i e twice the horizontal and vertical resolution respectively Hex adecatuple H Sixteen times as many pixels compared to the base resolution i e four times the horizontal and vertical resolutions respectively Super S eXtended X Plus and or Ultra U Vaguer terms denoting successive incremental steps up the resolution ladder from some comparative more established base usually somewhat less severe a jump than quartering or Quadrupling typically less than doubling and sometimes not even as much of a change as making a wide version for example SVGA 800 600 vs 640 480 SXGA 1280 1024 vs 1024 768 SXGA 1400 1050 vs 1280 1024 and UXGA 1600 1200 vs 1024 768 or more fittingly vs the 1280 1024 of SXGA the conceptual next step down at the time of UXGA s inception or the 1400 1050 of SXGA Given the use of X in XGA it is not often used as an additional modifier e g there is no such thing as XVGA except as an alternative designation for SXGA unless its meaning would be unambiguous These prefixes are also often combined as in WQXGA or WHUXGA with levels of stacking not hindered by the same consideration towards readability as the decline of the added X especially as there is not even a defined hierarchy or value for S X U modifiers
