Why would an LCD display use a modeline?
Surely the resolution is fixed by physical pixels, and sync pulses are
irrelavant. Perhaps they try to emulate a CRT-scanning video card?

There are more variables to consider. A sync problem most likely means
your h-freq is too high. Try reducing the retrace/blanking time.

The monitor is analogue, so no effect. Modeline is just resolution, and
timing - width of blanking and sync pulse in "pixels".

How many MCSEs does it take to change a light bulb?
