I finally opened and set up my Spectrum yesterday. So far it’s kind of a mixed bag, there’s a lot of things I like, and a lot I struggle with. This is an example of the latter.
I am currently using a MacBook Pro (13", 2017), connected with a single USB-C cable that should be able handle this as far as I know. This is a cable that came with and I have been using with my previous monitor (LG UL850-W), providing 4k@60, PD (60W), and USB pass-through.
I have two USB devices plugged into the Spectrum (a mic and a DAC/AMP), neither of them are visible to macOS. I am using the exact same cable mentioned above, so I am baffled why it doesn’t work when it was with the LG.
- The monitor has FW 104, updated it yesterday.
- To get 4K@60 I had to switch the bandwidth priority to “High refresh rate”, but even if I switch it to “High USB data speed” and get stuck at 30Hz, the devices are not visible.
- Similarly, it doesn’t matter if I change the hub selection between automatic and Type-C, or if I set the USB hub to be “Always on” or not.
- The USB devices do get power though, so the ports themselves seem to work.
I have a new MBP on the way, for which I also plan on getting a higher spec cable. It might solve it, or it might not. But that’s 1-2 weeks away, would prefer to fix this before then if possible. Would also love to understand at least why the current setup doesn’t work, why I only get 4K@30 with the high data speed setting (I believe that should support 60Hz), but more importantly, why my USB devices are not visible on the Mac, when this exact setup was working with the LG, only the monitor changed.
Any answer, help, and insight is appreciated! <3
