I have just replaced the screen on my dell Insprion 6000 with a Dell Latitude D810 LTN154X2-L02

Now the screen Res will only go to 800 x 600 and no higher.

The device manager shows 2 monitors and there is 2 options under display options (defult) and other.

How do i get rid of the old monitor and up the res on the new one?

Thanks
