Error message

[MarcusOy]

When I connect to a server, my monitor turns black and in a windows alert pop up window, it says:
"initdirectdraw failed: 0x80004001"
My laptop disconnects my secondary monitor (it is big, and i tried to play AoS on it) and returns me to the website
on the laptop monitor. My big monitor's model is a "HP 2311x".
Can someone please tell me how to fix this problem?
Thank you.

Edit: Returns me to website on the same monitor after error.
