Today tried to connect Dell Inspiron 7437 to external monitor using HDMI cord; it did not work. I changed setting to external monitor only and now cannot get an image on laptop screen or external monitor when HDMI cord is connected. Tried to restart computer; still goes to blank screen as soon as I plug in HDMI.
1. How to a return to default setting for laptop display so it's only set to laptop?
2. Is it possible to connect inspiron 7000 to external monitor with hdmi?
Thank you
