I have seen alot of posting on this subject in the last several articles. I
just wanted to add that I use a VRAM card (Video-7) with a NEC 3-D and I do
NOT get these little popping noises. I am not positive that this is a normal
function of all multisync monitors. Some of the other machines around the
office do have popping symptoms when starting and ending graphics mode 
programs.
