I have the Triple Display USB-C docking station, plugged into a Dell Latitude 5580. I have an ASUS monitor and a ViewSonic monitor. I have multiple HDMI cords.
I have tried each monitor, with each cord, with the 4K HDMI port on the docking station with success. However, with any cord, I cannot get either monitor to connect on the 2K HDMI port. I have also tried DVI, on both monitors, with no success.
In all other functions, the dock seems to be working great. It’s feeding power back to the laptop. It’s connecting my USB keyboard and mouse. It’s successfully using gigabit. It’s even charging my Pixel. But, no function on the black video ports.
Help? I went out on a bit of a limb here, selling the idea that this dock could take care of all of our connectivity needs, and the most visible feature isn’t working for us. Yikes.
