Question about Dell Latitude C640 Notebook

1 Answer

Dell latitude display settings

I do not have a drop box for my display settings. All that comes up is
the ATI AGP 2X (DELL) so I can not hook up to any outside monitor.

On most Dell laptops it's not listed on the display settings. You have to enable it manually.

On the bottom left of your keyboard you'll see a blue Fn (function) key. Hold that down and scan your F keys at the top of the keyboard. You're looking for one that has (in blue, like the Fn key) CRT/LCD marked on it. Hit that and then let up on both keys. It has three settings 1) internal LCD, 2) external CRT (cathode ray tube, but an external LCD applies, too) and 3) both internal and external (this can be a little tricky with older video cards, especially when used with something like a projector). Each time you use the CRT/LCD switch it toggles between these three modes.

Let us know how it turns out!
