RGB and VGA signals (and their cousins SVGA, XVGA etc.) are analog component delivery systems. They split the signal into component parts that are carried by multi-coax or multipair cables. The delivery time of each pixel component is critical for resolution and picture detail, called "timing" for coaxes, and "delay skew" for twisted pairs. This paper will show how far you can go in different variations of coax and twisted pair cables, how it is related to screen resolution and pixel size, and how you can calculate these distances yourself.
