I have an HP 450 G5. I don't have a docking station as this laptop isn't made for one, so I'm running two ext monitors. One plugged into the VGA and one plugged into the HDMI. When I go to the display settings the two external monitors and the laptop screen are present. I successfully set one of the monitors as the primary screen and then successfully set the other monitor as extended desktop. I then changed the power settings so that with it plugged in, closing the lid does nothing. As soon as I closed the lid, the monitor plugged into the HDMI turns off. As soon as I open the lid, the monitor plugged into HDMI comes back. The "main" external monitor always stays on as expected, regardless of lip being open or closed. How the heck do I keep the HDMI active with the lid closed?
