Hello! I need help with my daughter's computer. She has a Dell Inspirion and flat screen monitor. She was playing Zoo Tycoon which she has played many times before and suddenly the screen came up with: "Auto Detect (analog input) cannot display this video mode optimum resolution 1440 x 900" and it won't go away. We've restarted the computer with and without the monitor connected to the computer and we've done a systems restore. It works in the safe mode but once we return to the normal mode we get the same error. I hope this in enough info to allow someone to help. Thank you in advance!
