I just received a UD-CA1 docking station and plugged it to my 2015 retina Macbook, and hooked the dock to my Epson EH-TW480 projector (720p) with an HDMI cable. Everything works but HDMI. Mac OS X recognizes the projector in system preferences, but on the projector I get a « no signal ».
I tried restarting both the computer and projector. I also tried both the included USB-C cable and a 2-meter Plugable Thunderbolt 3 cable. No luck. Can you help?
The HDMI cable and projector worked well with a small USB-C to HDMI adapter (similar to the Apple USB-C multiport AV adapter).
