How can I plug off LCD display of an Acer TravelMate P253?

I have a broken laptop screen and I want to make my external monitor the main monitor.

I'm not positive, but I believe you would get what you want by disconnecting the LVDS Cable from the motherboard. I don't believe there's anything else served by the cable except the display, but the risk is that something like the camera is also on that cable, which would stop it from working. A harder mod would be to remove the LVDS cable at the display panel or removing the panel itself. Any of those would make it so the system saw your external monitor as the only display so the OS would use it as primary.
