USB C works for an external monitor when connected through a hub but not directly??
I’m having a strange issue with my portable monitor:
Connecting the monitor directly to my laptop’s USB-C port → it does not work.
Connecting the same monitor using the same USB-C cable through a USB-C hub (from the exact same laptop USB-C port) → it works perfectly.
The hub is not connected to external power.
This exact monitor worked with a previous laptop with the same C-to-C cable.
When I initially couldn't use this port directly, I chalked it up to having a non-display support USB-C port... But now it workks through a hub?!!?
Does anyone know why this happens? Is the hub changing the USB-C negotiation, enabling DisplayPort Alt Mode differently, or is there some compatibility issue between the laptop and monitor?
Would appreciate any insights from people familiar with USB-C/DisplayPort Alt Mode! 🙏
