How to connect your monitor to your PC

There are currently 2 forms of display, the CRT (Cathode Ray Tube, large picture-tube style) and the flat panel (LCD style). But there are also 2 forms of display signal, analog (modulated wave form) and digital (data in streaming bits). CRT monitors are largely analog while flat panel monitors are digital, but can also accept analog signal.
