Explanation

VGA (Video Graphics Array) outputs an analog signal. DVI-D carries a digital signal. A VGA to DVI adapter must perform analog-to-digital (A/D) conversion to bridge these two standards. S-Video to RCA is analog to analog - no conversion. HDMI to VGA converts digital (HDMI) to analog (VGA), which is the opposite direction. DVI to HDMI is digital to digital - DVI-D and HDMI share the same underlying digital signal format and only require a passive adapter. Therefore, VGA to DVI is the only option that converts analog to digital.
