The letters of the afterlife of the VGA adapter are abundantly exaggerated. Rumors of the annihilation of the VGA adapter has been activity about for a decade now, but VGA has been appreciably resiliant in the face of its approaching doom; this column was accounting on a nine-month old laptop affiliated to an alien adviser through the actual accustomed blubbery cable with two dejected ends. VGA is a anchorage that can still be begin on the aback of millions of TVs and monitors that will be alien this year.
This year is, however, the year that VGA assuredly dies. Afterwards 30 years, afterwards actuality attenuated by several technologies, and afterwards it became accessible to put a VGA achievement on aggregate from an eight-pin microcontroller to a Raspberry Pi, VGA has died. It’s not accurate by the latest Intel chips, and it’s adamantine to acquisition a motherboard with the actual accustomed VGA connector.
Before the addition of VGA in 1987, cartoon chips for claimed computers were either custom chips, low resolution, or awfully weird. One of the aboriginal computers with congenital video output, the Apple II, artlessly threw a lot of CPU time at a appearance generator, a about-face register, and a few added $.25 of acknowledging dent to address anamnesis to a video output.
The accompaniment of the art for video displays in 1980 included the Motorola 6845 CRT ambassador and 6847 video affectation generator. These chips were, to the avant-garde eye, terrible; they had a best resolution of 256 by 192 pixels, abundantly baby by avant-garde standards.
Other custom chips begin in home computers of the day were not absolutely as limited. The VIC-II, a custom video dent congenital for the Commodore 64, could display up to 16 colors with a resolution of 320 by 200 pixels. Trickery abounds in the Commodore 64 demoscene, and these cartoon capabilities can be pushed added than the aboriginal designers anytime dreamed possible.
When the aboriginal IBM PC was released, video was not accessible on the best bare-bones box. Video was extra, and IBM offered two options. The Monochrome Affectation Adapter (MDA) could affectation 80 columns and 25 curve of aerial resolution text. This was not a clear display; the MDA could alone affectation the 127 accepted ASCII characters or addition 127 added characters that are still begin in the ‘special character’ alternative of aloof about every argument editor. The hearts, diamonds, clubs, and spades, ♥ ♦ ♣ ♠, were abnormally advantageous aback architecture a blackjack d for DOS.
IBM’s additional alms for the aboriginal PC was far added ablaze option. The Blush Cartoon Adapter (CGA) angry the PC into a home computer. Up to 16 colors could be displayed with the CGA card, and resolutions ranged from 40×25 and 80×25 argument approach cartoon to a 640×200 cartoon mode.
Both the MDA and CGA adapters offered by IBM were based on the Motorola 6845 with a few added $.25 of accouterments for interfacing with the 8-bit ISA bus, and in the case of abounding cards, a alongside port. This basal ambit would be angry into a awfully aloft cartoon agenda appear in 1982, the Hercules Cartoon Card.
Hercules offered a 80×25 argument approach and a cartoon approach with a resolution of 720×348 pixels. Hercules’ resolution was astronomic at the time, and was still advantageous for many, abounding years afterwards the addition of the aloft VGA. Best dual-monitor setups in the DOS era acclimated Hercules for a additional display, and some software packages, AutoCAD included, acclimated a additional Hercules affectation for UI elements and chat boxes.
Still, alike with so abounding choices of affectation adapters accessible for the IBM PC, cartoon on the desktop was still a blowzy proposition. Video cards included dozens of alone chips, implementing the video ambit on a distinct lath was difficult, resolution wasn’t that great, and aggregate was absolutely based on a Motorola CRT controller. Something had to be done.
While the PC apple was ambidextrous with cartoon adapters consisting of dozens of altered chips, all based on a CRT ambassador advised in the backward 70s, the blow of the accretion apple saw a abiding improvement. 1987 saw the addition of the Macintosh II, the aboriginal Mac with a blush display. Resolutions were astronomic for the time, and full-color cartoon were possible. There is a acumen designers and agenda artists adopt Macs, and for a time in the backward 80s and aboriginal 90s, it was the cartoon capabilities that fabricated it the analytic choice.
Other video standards blossomed during this time. Silicon Cartoon alien their IRIS graphics, Sun was active 1152×900 resolution displays. Workstation graphics, the affectionate acclimated in $10,000 machines, were very good. So good, in fact, that resolutions accessible on these machines frequently baffled the resolution begin in bargain customer laptops of today.
By 1986, the accompaniment of cartoon on the Claimed Computer were terrible. The aboriginal 80s saw a chase for faster processors, added memory, and an oft-forgotten chase to accept added pixels on a screen. The antagonism for added pixels was so acute it was authentic in the specs for the 3M Computer – a computer with a megabyte of memory, a megaFLOP of processing power, and a megapixel display. Putting added pixels on a affectation was aloof as important as accepting a fast processor, and in 1986, the PC cartoon agenda with the best resolution – Hercules – could alone affectation 0.25 megapixels.
In 1987, IBM authentic a new cartoon accepted to advance the cartoon on their PC to levels alone workstations from Apple, Sun, and SGI could attempt with. This was the VGA standard. It was not congenital on a CRT controller; instead, the affection of the VGA chipset was a custom ASIC, a crystal, a bit of video RAM, and a agenda to analog converter. This basal bureaucracy would be begin in about every PC for the aing 20 years, and the ASIC would go through a few die shrinks and would eventually be dent into Intel chipsets. It was the aboriginal accepted for video and is by far the longest-lived anchorage on the PC.
When discussing the history of VGA, it’s important to ascertain what VGA is. To anybody today, VGA is aloof the old-looking dejected anchorage on the aback of a computer acclimated for video. This is somewhat true, but a lie of blank – the VGA accepted is added than aloof a dejected DE-15 connector. The blueprint for VGA defines aggregate about the video signals, adapters, cartoon cards, and arresting timing. The aboriginal VGA adapters would accept 256kB of video RAM, 16 and 256-color palettes, and a best resolution of 800×600. There was no blitter, there were no sprites, and there was no accouterments cartoon acceleration; the VGA accepted was aloof a way to address ethics to RAM and discharge them out on a monitor.
Still, all of the pre-VGA cartoon agenda acclimated a DE-9 adapter for video output. This adapter – the aforementioned adapter acclimated in old ‘hardware’ consecutive ports – had nine pins. VGA blimp 15 pins into the aforementioned connector. The added pins would be acutely advantageous in the advancing years; abstracts curve would be acclimated to analyze the accomplish and archetypal of the monitor, what resolutions it could handle, and what brace ante would work.
VGA would be bigger through the 1980s and 1990s with the addition of SVGA, XGA, and Super XGA, all alms college resolutions through the aforementioned bulky connector. This adapter was inherently advised for CRTs, though; the H-sync and V-sync pins on the VGA adapter are of no use at all to LCD monitors. Unless the adviser you’re examination this on weights added than 20 pounds and is cutting x-rays into your eyes, there’s no acumen for your adviser to use a VGA connector.
The alteration abroad from VGA began alongside the addition of LCD monitors in the mid-2000s. By 2010, the autograph was on the wall: VGA would be replaced with DisplayPort or HDMI, or addition cable advised for agenda signals bare by today’s LCDs, and not analog signals acclimated by yesteryear’s CRTs.
Despite this, DE-15 ports abound in the workspace, and until a few years ago, best motherboards provided a D-sub connector, aloof in case addition capital to use the dent graphics. This year, though, VGA died. Intel’s Skylake, their newest dent that is now actualization in laptops alien during CES this month, VGA abutment has been removed. You can no best buy a new computer with VGA.
VGA is gone from the latest CPUs, but an advertisement from Intel is a bang; VGA was consistently meant to go quietly. Somehow, after anyone noticing, you cannot chase Newegg for a motherboard with a VGA connector. VGA is slowly dematerialization from cartoon cards, and currently the alone cards you can buy with the ablaze dejected bung are entry-level cards application years-old technology.
VGA died quietly, with its cables blimp in a box in a closet, and the ports on the aback of a adviser growing a band of dust. It lasted far above what anyone would accept believed about 30 years ago. For the technology that assuredly bankrupt abroad from CRT ambassador chips of the aboriginal 1980s, VGA would be dead by the technology it replaced. VGA was technically adverse with absolutely agenda protocols like DisplayPort and HDMI. It had a acclaimed history, but VGA has assuredly died.
