External display not turning on via Belkin USB-C hub on Mac Studio M2

I have a new Mac Studio M2 running Sequoia 15.2. I plugged in a Belkin USB-C hub to the back of the Studio. When I attached a 2nd display (an NEC MultiSync P221W) to the hub, the display will not turn on. However, when I connect it directly to a USB-C port on the back of the Studio, it works fine. I do not have the same problem when I connect an external back-up drive to the hub. Could someone please offer an explanation? Thank you so much.
