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.

Request to make the product better, right angle usbc to host, quarter 20 thread
Style: 5-in-1 Display Hub
I have the old iteration and could really use a right angle usbc to host.
Belkin - this is not a review, rather a request for this product on your next iteration. Phone filmmaking is on the rise right now, and this could be your opportunity for this product. Please make this a right-angle USB-C, and a bit longer, maybe 8 inches if you want your USB-C fixed. Or just make a hub without a fix USB-C to host, that lets the user attach their USB-C cables, and put a quarter 20 thread in the middle of the body. Actually we want a product that looks like the Blackmagic Pro Dock, but just a plain hub, smaller. 1 tb5 usbc to host, 2 tb4 usbc, a hdmi mini/regular and a 140w PD. A right-angle USB-C to host is extremely important for phone usage. Is it difficult to make it right angle?
