I have a Nvidia GeForce MX 4000 graphics card with XP Pro and SP2 and a CTX EF710F monitor.
I have loaded the drivers using the AOpen CD provided
More often than not, when I boot up, the screen comes up too narrow. If I then change to a higher resolution but then revert back to the 1024 x 768 resolution I like to use and a refresh rate of 100 Hz all is well. But not at the next boot up.
