I am using NVIDIA GeForce GT710 graphics card. I tried every driver by nvidia. nvidia-396, nvidia-390, nvidia-390. All gave the issue of reduced resolution in the second screen connected via HDMI-0. Whenever I try generating xorg.conf file using nvidia-settings, I get a blank second screen.
$ uname -r 4.4.0-131-generic
Tried Getting screen resolution correct with nvidia drivers, but generating an xorg.conf file results in the second screen getting blank.
The second screen can support 1920x1080_60. Tried adding using xrandr, newmode and addmode steps. It doesn't help either.
