This seems to be an "old" topic, but what the heck, I don't get to the News
very often...

  My father is a professional photographer and is occasionally called upon
to photograph a computer display; as I recall, he usually puts the camera
on a tripod, uses as "long" a lens, at as much of a distance, as is feas-
ible (i.e. he can't, if there's no space to "move back"), then TURNS THE
AMBIENT (room) LIGHTS DOWN OR OFF and uses an exposure anywhere from 1/30
to SEVERAL seconds, depending on the light level coming from the display.  If
the client wants also to show the computer itself, WITH display image, 
Dad will fire an electronic flash unit AFTER exposing for the display, 
thereby giving brief illumination to the surrounding objects...
