LG 32UD59-B 32" Ultra HD 4K Monitor
Thanks for reaching out to us, I am happy to help.
The Plugable USBC-DP USB-C to DisplayPort Cable ( https://plugable.com/products/usbc-dp/ ) is able to support the transfer of video and audio to the monitor or television.
Assuming the operating system is Windows 10, lets start by checking to see what audio options are available, please perform the following:
- Right click on the sound icon in the system tray ( lower right corner of the screen )
- Select “Playback devices” from the menu
- Under the heading “Select a playback device below to modify its settings:” right click on each option and select “Test” from the menu
- If one of these available options outputs the test signal to the monitor, select “Set as Default Device” from the right click menu
Please let me know if this helps, or if none of these options output to the screen.
