Or 75Hz if you are in PAL-land. I too have a G400. The problem seems to
be to do with total video bandwidth so you have a choice of reducing
resolution, refresh or colour depth. I run at 1600x1200x16 at 85Hz with
good results but if I go to 24 bit colour the problem shows up.
1600x1200x24 at 75Hz is also too high, unfortunately.
