usermonitor :
R0GG, I have an HDMI cable that connectes the laptop to the external monitor.
Were you able to move your icons around ?
You could do
a MIRRORED LAYOUT and you'll have your laptop monitor mirrored onto your external monitor : people use this for clarity or for watching movies or in projection mode when external monitor is much larger and clearer than laptop one, with option of turning off laptop monitor all together .
Any output port would usually work well, VGA, DVI or HDMI , etc
Windows 10 is pretty neat with the Extended desktop layout,
You could use third party utilities such as ULTRAMON ( which needs a little of learning curve) either for switching quickly display modes and saving their configuration for quick display mode shifting, or for using the goodies of extra taskbar on the extra screen with configurable options,, extended desktop wallpaper throughout both screens or side by side different backgrounds.
you always have the options in windows to hide desktop icons (when taking advantage of your desktop taskbar and quick launch bar that you could activate easily in windows 10) and enjoy your extended desktop bigger wallpaper view.
