My resolution will change randomly, usually during start up and it is quite annoying because when it switches to one my monitor will display a "Not Optimum resolution" message in the middle of the screen that won't go away for 5 minutes. I have looked at these forums for other people with this problem and tried solutions suggested there (updating drivers, running selective start up). None of these worked and would like some other solutions that could solve this, because I have no idea why it is doing this.
