Screen goes black momentarily

Have noticed that, with WinXP (SP1 and all latest patches), the screen will
sometimes go black for a second, then the desktop (or, whatever I'm using)
comes back. It seems to not just happen with ATI, but, also with NVidia.

Any idea what's causing this? It happens on multiple PC's and laptops.

Thanks.

Most monitors, even on laptops, blank when they sense a signal change,
such as when changing resolutions. It's possible Windows does a bit of a
reset or something that causes a glitch in the video signal, fooling the
monitor into blanking.

I've also seen it happen when DirectX is initialized, or certain
features are checked (such as some tabs in ATI's control panel.)
