I keep my laptop tucked away and solely use an external display with it via HDMI. In Windows 7 display settings, I have it set up to "Show desktop only on 2 [my external display]" This works fine in all cases except when I boot the laptop when the external display is already connected. In that case, the laptop's display stays on and sticks at the Windows 7 boot logo unless I manually shut the display off. (I should mention that while the laptop's display is stuck at the boot logo, the external monitor and computer are running just fine.)

The laptop is an Asus N56VZ with Nvidia 650m graphics and the latest drivers. I've checked Nvidia's control panel as well as the BIOS and nothing looked very promising.

Any ideas as to how I can get my laptop screen to shut itself off after booting into Windows?
