Understanding the timing parameters won't help you figure out what works. If the standard timing parameters don't work, then there's no way to know what will work without trial and error. For the most part, the values don't matter much as long as the monitor can handle them.

Blanking = front porch + sync width + back porch
Total = active + blanking

Blanking is the period between each line (horizontal blanking) and each refresh (vertical blanking). Blanking was basically designed to give CRT monitors time to move the electron gun. LCD monitors don't need as much time to process the signal, so they can handle lower values.

The sync width is the duration of the sync pulse. The front and back porches are basically padding before and after the sync pulse. The sync polarity determines whether the sync pulse goes up or down in voltage. Most monitors don't care either way.
