Help?? I upgraded my Dell Inspiron 15R 5537 from Windows 8.1 to Windows 10. My ethernet stopped working as well as my WiFi. After two days of talking to Dell and Microsoft techs I was able to revert back to 8.1 and boot in safe mode with networking. I have sound that I enabled as well but, I would like to know if it's possible to enable HDMI while in safe mode? I have rescue disks on the way but need to connect to an external monitor via HDMI until then. Any help??
