In addition to this, it is also defined by the Video Electronics Standards Standards Association.įound on almost 80% of laptops, XGA was introduced by IBM in 1990.

Below is a table of the most common ones:įirst released in 1987 with IBM’s PS/2 computers, the resolution is also called “standard definition” compared to HD (“high definition”) and Full HD.Īlso known as Ultra Video Graphics Array (UVGA or Ultra VGA), it was released as a VGA extension by IBM in1987. There are some variations of VGA that refer to specific screen resolutions. The pins/holes run across three rows, with each pin/hole performing a different function, such as providing red/green/blue (RGB) color information, power, vertical or horizontal syncing, and electrical grounding.Īn example of a male VGA connector VGA Resolutions Often colored blue, it has both a male, 15-pinned form and a female 15-holed form.

Portable devices, from smart phones, to tablets and game consoles Very high resolution displays, such as those used for 3D animation and gaming computers, WQUXGA standard HDMI connectors come in 5 different types:Īll high-definition standards, all models of TVs and computer screens If HDMI cables are used with a VGA port, a converter unit and separate cable are needed to hook up the video display and provide the audio signal to a separate port. Even with converters, video signal quality is greatly compromised when using VGA cables, so they usually serve as a stop-gap measure. VGA cables are incompatible with HDMI ports, except with the use of converters. Using low-quality, unofficial adapters can increase input lag significantly as well. Technically, every additional device introduces some delay because of the extra distance electrons have to travel, but this is negligible. There is an option on some TVs called “Game mode” which also disables post-processing.Īnother factor in input lag is the use of adapters. While disabling post-processing reduces image quality slightly, it decreases input lag. Post-processing is similar to a Photoshop filter, in that it applies effects, such as depth of field, motion blur, and color correction.
VGA connections generally exhibit less input lag than HDMI connections because they don’t apply post-processing on the input.

Input lag can refer to one of two things: the delay between a display device, such as a TV or monitor, receiving a signal and displaying it, or the delay between pressing a button in a video game and seeing the game execute the corresponding action.
However, most standard HDMI cables offer excellent connections and solid performance without the need for premium cables at premium prices. To avoid this issue in tight places with several cables, the best HDMI cables offer thick insulation. HDMI cables are less sensitive to crosstalk, but can suffer interference from electromagnetic fields. VGA cables are subject to crosstalk (signal interference from other cables) and length issues for beyond about 4 feet, the analog video signal tends to break down. Because it supports digital copy protection of all signals, HDMI cables are included for devices such as the Apple TV, Blu-Ray players, and game consoles, among other similar electronic products. The HDMI standard allows for the transfer of both digital video and audio signals via the same interface (port) and cable, capable of providing high-definition (HD) video at resolutions of 1,920 x 1,200 pixels and 8 audio channels simultaneously. In addition analog signals carry less information than digital, so the original image such a scenario starts out as less "sharp" than what can be achieved in digital. The analog signal would lose some information in the conversion to digital, and more information is lost when converted back to digital. However, newer display devices used digital signals, too, so the process became a two-step conversion from digital to analog and back to digital, with concurrent degradation of the signal. When digital signals became more common, VGA cables were enhanced with converters to enable an analog-to-digital conversion. At the time they were first released (1987), analog signals were the norm. VGA cables were designed to carry only video signals from a device to a display.
