https://proav.co.id/kabel-vga/ In the constantly changing tech world, where HDMI and DisplayPort connections dominate, the VGA cable is often overlooked—a previously crucial part for linking monitors and projectors. Nonetheless, knowing about VGA cables is still important, especially when dealing with older equipment or specific applications that require this form of connectivity. In this article, we will explore the background, use, and ongoing importance of VGA cables, providing a thorough understanding of their role in the tech ecosystem. The Video Graphics Array (VGA) standard was introduced by IBM in 1987, representing a notable progression in computer display technology. This analog interface quickly became the industry standard for connecting monitors to computers. The VGA cable typically features a 15-pin connector, known as a DE-15 or HD-15, being recognized by its trapezoidal form and blue color. Despite its analog nature, VGA was revolutionary at the time, supporting resolutions up to 640x480 pixels with 16 colors or 256 colors in a lower resolution mode. One of the key aspects of VGA cables is their analog signal transmission. Unlike digital connections that transmit binary data, VGA sends signals as varying waveforms depicting different levels of RGB light intensity. Due to its analog nature, VGA cables are prone to signal deterioration over long distances—a constraint mostly addressed by digital connections. However, for short distances, VGA provides a reliable means of transmitting video signals without significant quality loss. Although electronic interfaces including HDMI and DVI have mostly replaced VGA in current technology owing to their enhanced image quality along with features like audio transmission and HDCP (High-bandwidth Digital Content Protection), VGA cables still have worth in particular cases. A lot of older displays and projectors solely use VGA input, making it necessary in educational and business environments. Additionally, as VGA
