I’m trying to connect a second display to my tensorbook. So far I cannot get it to even detect any connected second display exists.

Any end-to-end guide that covers monitors, input types, etc.?

Below are details on laptop and the two monitors I’ve tried, plus steps I tried to get the laptop to detect each monitor.

LAPTOP: tensorbook laptop  
Ubuntu 18.04.1 LTS  
graphics: Intel® HD Graphics (Coffeelake 3x8 GT2) (from Settings/About)  
GPU: nvidia GeForce GTX 1070

MONITOR: ViewSonic VX2450WM-LED

STEPS:

- connected monitor DVI =\> MiniDisplay Port on laptop (tried both)
- open Settings/Devices/Displays

EXPECTED:

- should detect display

OBSERVED:

- displays on basic options about ‘Built in Display’

STEPS:

- from terminal: nvidia settings

EXPECTED:

- launch some app to configure second display

OBSERVED:

- ERROR: Unable to find display on any available system

MONITOR: HP2311x

STEPS:

- connected monitor HDMI =\> HDMI Port on laptop
- open Settings/Devices/Displays

EXPECTED:

- should detect display

OBSERVED:

- displays on basic options about ‘Built in Display’
