Thanks Grant,
I understand by your link that my computer is too old to connect it through the Apple USB-C Digital AV Multiport Adapter.
> 3840 x 2160 at 60Hz with these devices: 15-inch MacBook Pro introduced in 2017 or later).
But in the tech specs we find something different:
MacBook Pro (15-inch, 2016) - Technical Specifications
Video Support:
Simultaneously supports full native resolution on the built-in display at millions of colors and:
- Up to two displays with 5120-by-2880 resolution at 60Hz at over a billion colors
- Up to four displays with 4096-by-2304 resolution at 60Hz at over a billion colors
Thunderbolt 3 digital video output
- Native DisplayPort output over USB‑C
- VGA, HDMI, and Thunderbolt 2 output supported using adapters (sold separately)
The LG monitor has 2 HDMI and a DisplayPort conector. Should I try a DisplayPort cable? Am I understanding something wrong here. Thank you and thanks everyone!!!
