I have a ThinkPad T480 combined with a Pro dock (side). I was hoping to use 3 external monitors (not including the laptop screen).
The pro dock only has 2 display ports and the laptop has a HDMI port which i was hoping to all use to get my 3 displays.
My setup is 2 VGA external monitors to display port adapters and 1 hdmi monitor to the laptops hdmi port directly. 2 display port monitors display fine, however the HDMI display goes black. If i un dock the laptop, the HDMI monitor works.
Can i not output all 3 at the same time, i know the laptops chipset allows 3 monitors.
I was thinking of buying a USB C to HDMI adapter for the 3rd monitor, maybe this would resolve it?
thanks in advance
