OT: how to set up 2 monitors with exactly the same colours?

[bibo]

Sorry for the slightly OT, but I thought that you may have encountered the same problem.

I have a Matrox P750 and I use it for video editing and CG in general.
I have 2 19" Compaq CRT monitors and I would like to set them up so they display exactly the same colours.
I have used DisplayMate (a powerful professional utility to analayse monitors) in combination with PowerDesk utility (fine adjusting RGB's Gamma), but I do not achieve the desired results - the Whites or Blacks of one monitor are always different from the other one. This is very apparent when I stretch any window over the 2 monitors: the background, either white or grey, is always visibly different between the 2. This is quite bothering!

Have you managed to perfectly adjust your 2 monitors?
How did you do it?
Do I have to use an external hardware Spectrophotometer?

Thanks.

Hi welcome I used a dvd called video essentials to set up the monitors. Mind you I'm not using a P750. but I believe by setting each monitor up individually using something like Video Essentials it would make the 2 monitors as close as you will ever get to each other without a broadcast standard monitor.
This dvd sets up similar to broadcast setup.Worked for me

Have you've tried the Coloreal program from the CD?

With CRT monitors, you will rarely get two, even of the same model, that are set up identically. Just look at a "wall" of TV sets in a shop and show me which two have identical colours.

In the factory (which will probably not be a Compaq one, but an obscure one in China or Korea), the gain and other trimmers will be set to give an approximation of the right results, with a wide tolerance. To get each one exactly identical would take skilled personnel over an hour to do, even assuming the convergence is perfect (rare). Software tweaking of the graphics card will never perfectly compensate for these tolerances as the number of variables is too great. If you can find someone expert in colour adjustments of monitors, he would do what you want, but it will probably cost you as much as the monitors themselves

Why do you adjust the gamma instead of Brightness/Contrast when the whites and blacks are the problem?
Keep in mind that two monitors of different ages (or different amount of usage) could differ greatly even they are the same model.
