I bought a PowerExpand 8-in-1 recently to pair with a brand new HP Pavilion 14t-dv000 and I am having troubles getting any video output on the 2x Acer CB272U monitors (QHD) connected to it.
The USB port of the laptop is specified as this: 1 SuperSpeed USB Type-C® 10Gbps signaling rate (USB Power Delivery, DisplayPort™ 1.4, HDMI 2.0, HP Sleep and Charge)
The processor is a brand new i5-1135G7 with integrated Iris Xe graphics, which appears to be capable of supporting up to 4 displays at 4k@60hz each.
I thought I should be able to comfortably drive just 2x QHD external displays over this hub? The integrated display is only a FHD display, so it seems well below what the Xe graphics can do?
Anyway, the system recognizes the monitors when I connect them, but the monitors don’t show any signal. I tried lowering the resolution on them to only 1920x1080, but nothing either. I tried connecting just one to the hub, still nothing. When I connect them directly to the HDMI port, they work just fine.
Any thoughts? Defective hub? All the other ports on the hub work just fine, including ethernet.
