That could simply be because when driven by that video circuitry the 
frequencies and timings are different and they do not produce the same 
electrodynamic stresses on the the monitor's inductive components (the 
flyback transformer, e.g.).

Are all the basic sweep paremeters the same between the two graphics 
adaptors? That is, the horizontal and vertical resolution and, very 
importantly, the vertical refresh rate.
