I think this is more likely to be an issue with the graphics adapter than
with the monitor. The monitor has no way of knowing if the CPU is under
load or not and therefore cannot react to it. The graphics adapter, OTOH,
could be experiencing EMI from the CPU fan as it steps up power with the
CPU heating up, or maybe just reacting to the extra heat from the CPU if
it's near enough. Or maybe the shielding in the Sub-D connected to
the monitor is bust.
Either way round we don't have enough information to go on here, but I
expect the problem is not the monitor in any case.

More to the point, what type of CPU is it, what kind of graphics card on
what bus, and how far away from the CPU?
