VGAliitännöillä

VGAliitännöillä refers to connectors and cables used for the Video Graphics Array (VGA) standard, a display interface introduced in 1987 by IBM. The most common VGA connector is the DE-15, a 15-pin D-subminiature connector, though earlier versions used different pin configurations. This connector is typically blue and is found on older computer monitors, projectors, and graphics cards.

The VGA standard transmits analog video signals, carrying red, green, and blue color components along with horizontal and vertical synchronization signals. This analog nature means that signal quality can degrade over longer cable lengths or with poor shielding, leading to potential issues like ghosting or color shifting. Despite its age, VGA remains in use due to its widespread compatibility and low cost.

Modern displays increasingly utilize digital interfaces like HDMI or DisplayPort, which offer superior image quality, higher resolutions, and additional features. However, many projectors and older monitors still rely on VGA, making adapters and VGAliitännöillä a common sight in environments where legacy equipment is in use. The DE-15 connector is designed to be secured with two thumbscrews, ensuring a stable connection.
