I have a HP 8460p laptop connected to a docking station. When i hook up my Dell monitor(standard pin connection), the screens on both come up but blurry. Is there a way to blackout the laptop screen and use the monitor only?
Usually there is a way to do this with the laptop's keyboard.
You have to press the "Fn" key and then also another keyboard key like F4 or F8 (there should be a picture of a monitor-looking icon on the key) and it toggles each time you press the F key while holding down the "Fn" key.
