Same issue in here on Ubuntu 18.04.1 LTS. I have a Dell G3 3579 with Nvidia Geforce 1050TI. I've tried to use a Samsung SmartTV as a secondary display connected to HDMI port but Gnome settings only shows laptop display. I've tested drivers 390, 396, 410, and 415 without success. This issue doesn't occurs using lightdm instead of gdm3. I think developers have to solve this issue that has been reporting since 2017-09-13 and people who wants do use a external HDMI TV/Monitor to play games, like me, will face this issue.
