DisplayPort Out question

[scoulber@protonmail.com]

So I finally got some video out via one of my hubs!
But...
Only when I had the USB-C cable in a certain way. When I inverted the orientation of the cable into the PPP, the functionality went away. That was repeatable multiple times.

I am pretty sure I also read early on in one of these forums, that charging had a similar issue.
Now, I thought that USB-C should work right side up and upside down, equally. But this seems not to be the case.

Does this make sense to anyone, or am I off base?

Thanks

I should expand:
I was talking to one of the hardware guys at work, as we are moving to USB-C hubs for the Hotel stations, and he told me that when the peripheral devices, specifically, display devices were connected or disconnected from a plugged in hub, things got problematic, but if the peripheral devices stayed connected to the hub, and just the hub was connected / disconnected from the computer things were far more stable.. I got similar info from one of the hub manufacturers. This is what I was testing with a few different hubs, and finally got one of them to mostly work.
