LG Ultrawide and USB/Volume control

I have a LG Ultrawide hooked on my macbook (mid-2015 w/High Sierra) via HDMI. I would like have the USB ports from the monitor working with the Macbook and be able to control voulume.

If I hook the macbook and monitor with a Thunderbolt cable (the monitor supports Thunderbolt), would that work?

Thank you,
Michel

What does the manual for your exact model number monitor tell you?

The user manual does not address this topic. Nor does the software guide.

Did you look for the model number for the monitor? You did not provide it, in order for anyone to help you?

The model number is 34UC98. But that question could be asked for any model of monitor with speakers and USB port.

My question is simple: will linking my mac with a thunderbolt cable with a non-Apple monitor do the job?

And the simple answer is: It depends on the monitor. Hence, you need to find a technical spec or more detailed user manual for that monitor to see if it supports that interface that way.

OK. I went here: http://www.lg.com/us/support-product/lg-34UC98-W#manuals
and I looked at the manual. It was totally silent on the subject of both. But under USB (page 20) it does imply that the ports are a USB hub. Whether or not that hub is attached to the Thunderbolt port in the monitor is not clear. But again, on page 21, under "Thunderbolt connection," it says that "Peripheral devices connected to the USB IN port can be controlled from the PC" which implies that the USB hub is, in fact, attached through the TB interface.

From that, it would appear that if you use a TB cable, the monitor should work to connect attachments to the USB. Whether or not you can control volume is totally missing from the manual, as far as I can tell.

It does with my PC. What would be the point of having USB ports on the monitor if it cannot interface with the PC?

Thanks. It was not clear, but it should work.

This information was not provided in your OP. If it worked with my non macOS PC, I would try it with my macOS portable PC (MBP or MB or MBA),
