The video cards should not affect the monitor colours - the phosphors
are probably the problem - unfortunately the only way I know to calibrate
them is with a display reading spectrophotometer like the Gretag
Spectrolino.
If you go through the normal procedure of setting the white point and
the gamma identically for each monitor and choose a standard monitor profile
like the sRGB IEC61966-2.1 or any pro sRGB profile (the wider RGB gamuts are
for film and transparencies) you may then be able to guage the difference in
Pshop by filling a window with solid 255 Red, Green or Blue on each monitor
- then try 128 levels for each colour. If one is brighter than the other you
may be able to tweak the gamma to improve the dull monitor but basically if
the phosphors are at fault the levels will not match unless you set the
better monitor to match the lesser with a spectrophotometer. The profile
generated by the spectrolino will set the 255 value to the best that you can
get on your worst monitor and automatically adjust all the other levels -
and you should have a perfect match - in theory.....could be other
components aging....

I used to have a spectrolino but I sold it to a guy in Mexico - too
expensive to get another.....
