The maximum resolution VGA can currently achieve is 2048 x 1536 pixels. XGA didn’t become a dominant standard or as ubiquitous as VGA. XGA was quickly superseded by SXGA (1280 x 1024) or WXGA (widescreen XGA and its different resolutions). ![]() IBM tried to upgrade VGA to XGA (extended graphics array) or the 1024 x 768 video resolution. Initially, VGA could only muster a resolution of up to 640 x 480. Note that VGA is backward-compatible with CGA, EGA, and other previous IBM video standards. Later, Big Blue released IBM PS/2 Display Adapter, a standalone VGA-based display adapter that one could add to devices that didn’t come with it built in. The very first implementation for the public was as a component integrated into the IBM PS/2. Initially, IBM didn’t release a discrete VGA card, unlike MDA, EGA, CGA, and the previous third-party options. It supported all graphics modes that MDA, EGA, and CGA cards supported, besides several new modes. IBM introduced VGA to address all the issues with a single graphics definition. However, its 640 x 350 graphics mode needed to be square enough for a 4:3 ratio. ![]() The EGA (Enhanced Graphics Adapter) card tried combining both text and high-resolution graphic modes. The CGA (Color Graphics Adapter) card suited pure graphical applications, such as playing games, but struggled with word processing or general computer usage due to its low-text resolution. It combined IBM’s purely text-based MDA display standard and a bitmapped graphics mode, facilitating both graphics and high-quality text with a single card. Hercules developed a clone card that could display graphics. It was only monochrome text mode and had no graphics modes. However, the issue with those adapters was that they were too specialized.įor instance, the MDA (Monochrome Display Adapter) card IBM introduced in 1981 was purely for texts. VGA Consolidated Different Graphics Capabilitiesīefore VGA’s introduction in 1987, different display adapters existed, and IBM also used them in their PCs. What are Some Other Video Standards Comparable to VGA? VGA Consolidated Different Graphics Capabilities.VGA uses analog signals in the world that has shifted to digital connection standards years ago.Īlthough an analog signal does not undergo processing like digital signals and does not exhibit input lag, it’s still no competition to the various other capabilities of the latest audio-video standards, such as HDMI (High Definition Multimedia Interface).Īnother area where VGA trails is “video resolution.” But how far behind is VGA? Is it capable of 2K and 4K resolutions? Can it at least manage 1080p signals? Having made its foray into the industry in 1987, VGA has undoubtedly been around for quite some time. The abbreviation “VGA” is instantly labeled as “old technology,” which is not incorrect. While VGA can technically achieve higher resolutions, it does not support 4K (3840 x 2160) without significant quality loss.VGA has evolved over the years, with its maximum achievable resolution currently at 2048 x 1536 pixels.VGA’s initial standard resolution was 640 x 480 pixels.How to convert HDMI to VGA or VGA to HDMI.How to convert DVI to VGA or VGA to DVI.However, converters can take the VGA signal to a connector supported by the video card. Newer video cards no longer have VGA connectors, which makes it difficult to use older displays. How can I connect an older VGA monitor to a newer computer? ![]() What are the most common symbols used by computers?.TTL (transistor-transistor logic) Ground (monitor self-test)Ī rectangle with two lines on the left and right side is a symbol used to represent the VGA connector on many computers and devices. ![]() As shown, the VGA connector has 15 holes, and each hole (pin) has its own function, as explained in the below chart. The illustration shows the 15-pin VGA connector, its pin assignments, and size dimensions. However, this type of connector is becoming obsolete and being replaced by the DVI (digital visual interface), HDMI (High-Definition Multimedia Interface), DisplayPort cable and connector. It is not uncommon to still find a VGA cable and connector with today's computers, monitors, projectors, and TVs. The VGA connector is used for display devices and is used to connect a computer to a monitor, projector, or TV. The VGA standard is replaced by SVGA (super video graphics array) and, although these cables and connectors are still called VGA, they are technically SVGA.
