I am having an issue with this dock (Startech.com USB-C Triple-4K Docking Station (DK30CH2DPPD). I have two Dell P2412H (1080p) monitors and a single ASUS VS247H-P (1080p) monitor. I was planning on using a two displayport to DVI adapters for the Dells and an HDMI to the ASUS.
I am using a Lenovo Yoga 900-13ISK (https://www.cnet.com/products/lenovo-…) with USB-C port. I am able to get the two Dells to display, but I am not able to get the HDMI to the ASUS to display. I have had a friend connect to a Mac and he was able to get all 3 montiors to display (using DisplayPort–>DVI to the Dells and HDMI to the ASUS). I also connected the displayport to DVI cable to the ASUS and it displays.
For some reason it does not detect a signal from the HDMI cable from my laptop, but it does from the Mac. Any ideas?
