Win7 on P4 Poor screen coloration
Issue : Attempting to upgrade to Win7 from XP Pro
All seems ok except extreme screen coloration problems at 800x600
which is the only display setting allowed.
Under XP Pro SP3, on a different HDD, there were no screen issues
and the Monitor ( HP vx74 ) performed as expected.

Monitor HP vx74 using
Microsoft Driver 6.1.7600.16385 which Win7 says is up to date

I know the MB and monitor are capable of good color at 800x600,
but don't know how to proceed.
Any ideas are appreciated.
