Over the years and with the large variety of hardware I've dealt with I've used quite a few of different video inputs and outputs. While I usually have no issue just plugging cables into devices, I really started to wonder how video cables differed from each other.
Could anyone specify the difference between s-video, rgb, rca, component, composite, vga, hdmi, displayport, dvi, and any others I'm forgetting? Why do these cables keep evolving; what does an hdmi cable offer that an s-video cable does not, for example? What are the advantages of using one cable/input over another? Refresh rate? Input lag?
