recently I’ve started to use 2nd external monitor. The connection is HDMI → USB-C hub → notebook. When connecting the hub to the notebook LAN and other USBs work just fine but the HDMI monitor is never recognized until I unplug it from the hub and plug it in again. I’ve tried with several other hubs and the behavior is the same hence I’d rule out the possibility it’s caused by the hub.
When the monitor is connected to the ntb directly (to hdmi port) it works just fine.
It’s getting pretty annoying to reconnect the monitor every time. Any ideas what might be the issue?
