New MacBook M1
 

Just bought the Visiontek VT4500 dock through Dell. Seems to. be passing power and ethernet over to the MacBook fine, but I am only getting 1 external display. I have 2ea Dell U2718Q 4K displays attached to the dock. The only monitor that is displaying is the one connected to the DisplayPort connector on the dock. I only have an HDMI cabke for the other monitor and it is not displaying anything. Do both monitors HAVE to be connected to the DPP?
