What type of signal does a VGA connector transmit?

A VGA connector transmits an analog signal. This technology interfaces with display devices to convey video information through varying voltage levels. The voltage levels represent the intensity of colors and brightness, sending data in the form of continuous electrical signals instead of discrete values.

Using an analog signal allows VGA to support various resolutions, although the quality of the image can degrade over longer cable lengths due to signal attenuation and interference. In contrast to the options involving digital signals and packetized video, VGA's fundamental design is rooted in analog transmission techniques, making it suitable for older displays and video cards that were primarily designed with this format in mind. The incorporation of audio signals is not relevant to VGA connections since they strictly cater to video output. Thus, the nature of VGA as an analog signal transmission aligns with the correct answer.
