I’m using the usb-c triple display dock with only one monitor. My laptop is the Macbook 12" (2015). The monitor is Dell U2412, which doesn’t have an HDMI input, and thus I’m using an HDMI to DVI adapter between the HDMI cable and my monitor.
If I plug the other end of my HDMI cable to the dock’s HDMI(4k) port, I don’t get a display. Interestingly, my Macbook appears to recognize the Dell U2412 display. However, if I use the dock’s HDMI-2k (Displaylink) output, the same setup (e.g. same adapter and HDMI cable) works and a proper display is shown. Similarly, the dock’s DVI output properly works.
How can I fix this? Thank you
