I own ASUS Zenbook 15, the UX534F model, and I'm looking for a way to attach two external screens to it. As far as I can tell, no official ASUS docking stations exist. The laptop comes with one HDMI port and one USB-C gen.2 but I'm unable to find out if the USB has the display option. I've tried attaching an Icy Box hub which connects via USB-C and offers, among others, HDMI and VGA ports but when I connect a screen to hub's HDMI port, no signal is detected (hub's other ports such as the Ethernet port work fine). My screens only have HDMI, VGA and display ports. Please help.
