Also please check whether perepherals such as CVT (Constant 
Voltage Transformer) and the like are placed below or beside the 
table housing the monitor. I have seen that electromagnetic fields 
from such things causing flicker in monitors. Try removing them 
or place something in between the two. That may imporve 
things...

Flickering is caused by a mismatch of the monitor and video card 
sync
rates. A graphics card is capable of delivering a given 
resolution (say
800x600) at various sync rates. The one which matches the monitor 
rates
most closely works best. Lighting can accentuate a flicker 
problem, it
can't create one.
