I have a 27 inch display LG27UD88-W which has two built-in USB 3.0 ports.
As far as I understand they should work out of the box if I connect my video card with the screen by DisplayPort.
Unfortunately, my computer does not recognize any USB device when plugged in to the screen ports. Mouse and keyboard didn't react neither. Is it possible that my video card does not support it or that a driver is missing? Or is it a defective screen?
My system: Windows 10 Pro, NVidia EVGA 980 Ti with multiple 4K screens connected by DisplayPort.

Your understanding is incorrect. There is a USB hub in your monitor, no different than an external USB hub. You need to connect a USB cable from your computer to the USB in port on your monitor and that will allow USB devices to work from your monitor.
