This isn't my ideal setup, but right now I have some work-from-home equipment which includes two HDMI monitors fed by a StarTech DK30 dock (product page below). In its intended use case, the dock takes a USB-C input from my work laptop and feeds a signal to my monitors. Works like a charm.
When I'm off the clock, I connect my personal desktop to one of the work monitors. The way I have it set up, I have to reach behind the monitor and swap out the dock cable for the one from my desktop and vice versa.
Instead of HDMI from my desktop, what I thought I'd do is use a DisplayPort to USB-C cable to feed video from my desktop to the dock just like my work laptop does. The problem is that I can't seem to get a signal.
I'm wondering if this is a compatibility issue, a bad cable, or what, but so far I'm coming up blank.
Possible key detail here: the laptop outputs USB-C directly to the dock, which I grant is different from taking my desktop's DisplayPort and feeding it to the dock's USB-C. If the problem is simply that the dock could can a straight USB-C signal and output to HDMI but NOT do the same with a DisplayPort feed to its USB-C input, I suppose that wouldn't be the strangest thing in the world to me. It's just that I've seen other setups where people run DisplayPort to USB-C via dock and output video with no problem. Granted, I think they also output to their monitors via DisplayPort - I haven't found any examples online of configurations exactly like mine.
Any ideas? Thanks for your time.
