A CRT has an electrom beam that sweeps across the screen left to right and top to bottom, and the horizontal and vertical sync frequencies control how fast the beam moves. An LCD panel does not have an electron beam; it has discrete, individually adressable pixels. If you insist on hooking it up to an analog port, it will have to convert the analog signal to a digital signal in order to display it, and you will get sampling artifacts, aliasing etc. I don't care how good you are at writing modelines; you will never come up with one that looks better than what you will get with a digital connection.
