Usb-c does not support video
Style: 5-in-1 Display Hub, Style: 5-in-1 Display Hub
Plugged it in works fine. 4 stars probably due to my own misunderstanding of port standards, but i thought the usb-c ports would be capable of video as well. They actually have an excellent graphic that comes with the item explaining this.
Usb-c does work with vr and I’ve not noticed a slow down. Hdmi port works, wish they made one with a 2nd as my laptops hdmi has begun going bad but oh well, this hub still puts me ahead.

Great hub for mirror less and cell phone
Style: 5-in-1 Display Hub
Works great with my Samsung Galaxy and a Sony FX30. It is an old S22 Ultra that I use as a monitor.
The cell phone is dead but the screen and the wifi are fine.
