Multi-Monitor (Laptop + Dell2001FP) Question

[awval999]

For anyone running a laptop/Dell 2001FP setup I have a question for you guys.

Do you notice that occasionally when you load up a IE window or something to that effect on the primary monitor that scan lines occasionally appear ON THE SECONDARY SCREEN during the loading of the item on the primary screen.

I have used both the laptop screen (1024x) and the Dell (1600x) as the primary screens and both times the secondary screens occasionally has the scan lines.

Is this normal?
