T480s USB C port doesn't work with external monitor or phone?

2019-10-12, 1:34 AM

I'm trying to connect the Mobile Pixels Duex monitor to my T480s. It connects via USB C-C. It doesn't work at all with the USB C port on the T480s. If I connect it by an USB A adapter to a USB A port (USB A port => USB A/USB C adapter => USB C-C Cable => Duex monitor) it does work.


Also, the USB C port has a very shaky connection with my phone (Pixel 2), and it has done so since I got the laptop last October. It was so bad that I had thought it was only a charging port—until one time when I plugged my phone in to charge and USB data options unexpectedly popped up. Since then, I've tried using it for data transfers to my phone; but, unless the file is very small, it will almost always disconnect partway through. Same thing with trying to use the USB C port for Unity Remote. Both data transfers and Unity Remote work perfectly fine when I connect my phone with a USB A-C cable.


Is the port broken or are USB C ports just not supposed to be good with data?
