Hi ChiefCob,
As Cmoses suggested, check your resolution settings (right-click on Desktop->Screen Resolution). If your running @ 1024x768, there will be several choices available for refresh rates (60hz, 70hz, 75hz, etc.). Select 1024x768 @ 60hz, and click "Apply". The resolution setting will switch, and you should now see scanlines on your display, click ok on the popup that asks you to accept the change and you are all set.
