This has to some extent been discussed earlier, however, I have not run across a communications that covers my situation. I already own a Matrox dual head G450 (as seen by Mandrake) - I can operate both monitors, but they are clones seeing the same view at differing resolutions with different overall physical sizes. Not satisfactory, but at least the configuration sees the card as a dual head with two different monitors with differing resolutions. When loading Fedora Core 3 on the same machine on a new disc, it identified the card as a Matrox G400 and while both monitors can be run they are forced to use the same resolutions, which could damage the smaller when run above its optimum setting. Explanation: they are both lcd types. If I choose FC3 and later 4, would I be able to have this card recognized as a dual head? Moreover, could I operate each monitor independently, e.g. one views the code being executed while the other sees the resulting application? TIA
