VGA CABLE

The VGA cable adapter is a special cable for connecting the VGA port (D-SUB) of the TV or monitor to the VGA port (D-SUB) of the graphics card. Most computers and external display devices are connected through an analog VGA CABLE interface. The digital display image information generated inside the computer is converted into R, G, B primary color signals and lines and fields by the digital/analog converter in the graphics card. The synchronization signal is transmitted to the display device through the data line. For analog display devices, such as analog CRT displays, the signal is sent directly to the corresponding processing circuit, which drives the control tube to generate an image. For digital display devices such as LCD and DLP, a corresponding A/D (analog/digital) converter is required in the display device to convert the analog signal into a digital signal. After the D/A and A/D2 conversions, some image details are inevitably lost. Connecting a digital display device is better with a DVI or HDMI type data cable.
