For the life of me I can not get my new Dell Inspiron one 2320 desktop to extend the monitor to my new LG TV model 44LV4400. I have tried every port on the computer, hdmi, component, VGA nothing works. The TV has all the ports hdmi, component, VGA also.

I have an Inspiron 7520 and uninstalled and reinstalled the new version of Dell Backup and Recovery Manager -- upgraded to premium to make sure that I would have full ability to use the program. Note: the old version didn't work at all -- hung up on backup, etc. I have rebooted.

I have a new 17R 7720 SE and can not access either F2 (Does not show up) for BIOS access and when I hit F12 Boot Options it shows but will not do anything it goes right to my Windows 8 Log in. How can I reset my BIOS to factory defaults ?
