USB 3.2 bandwidth can't support 4K @ 60 and support all those other connections at USB 3 speed at the same time. They could be claiming 60 Hz when other connections are using usb 2 speed. You believe what you want cause this is just waste of my time.

USB 3.2 (USB-C) peak theoretical data rate is 10 Gbps. 4K60p 4:4:4 (uncompressed) requires 17.82 Gbps without HDR (8 bit BT. 709 color). It is not possible to connect an RGB monitor at 4K60p unless it is being used in a TV mode with chroma sub-sampling such as 4:2:0 (4x compression).

So you are both correct. 4K60p output is possible with 4x chroma compression, but in general you would not want a computer monitor connected this way though it would be fine for a 4K TV.

As FYI TB3 peak theoretical rate is 40 Gbps. TB3 is included in the USB 4.0 spec.

Limitation due to bandwidth.

30fps HDMI port is a bummer.

Bandwidth of what, exactly?

And how is this adapter [amazon.com] able to support 60Hz 4K over the same connection?
Refer to some discussion on second page

That's all well and good, yet the product I linked has BOTH 4K @ 60Hz and USB 3 port.
And that product costs more than this so it seems like the more expensive unit supports Thunderbolt 3 specs. If your computer doesn't have TB3 then you won't get 4K @ 60.

Yes it costs more, but no, I don't see any requirements for TB3. Based on their compatibility list, I surmise that what this requires is Alternate Mode support on USB-C port. So, AFAIK, it's a matter of using more expensive chipset to enable 4K @ 60Hz and not a matter of USB-C bandwidth.

You're right on the bandwidth issue, which is why most of these hubs use either Thunderbolt 3 or DisplayPort (Alternate Mode). My guess is that the other Anker hub I linked uses Alternate Mode to deliver 4K @ 60Hz @ 4:4:4 (via an internal DP-to-HDMI conversion), which leaves you with 2 lanes to deliver USB 3.1 ports over. Alternate Mode for DP 1.4a (circa 2018) uses 4 lanes to deliver 25.92Gbps.

Some USB-C hubs specifically mention that they require support for Alternate Mode, but some don't. Doesn't mean that's not how they work.

I hope these adapters could has longer cable. There are few adapter with 3ft cable, or with detachable cable, but price range 35~45.

I got it from the previous deal and so far, it's a decent hub for $27.

I'm using a 60w PD charger with it which ended up being a bit disappointing. My laptop is only getting 45w.

Even when I don't hook up the hub to my desktop, the hub cannot seem to delivery fast charge to my phone at all. I tested with a second one of the same hub, same result.

DP Alt mode doesn't use USB bandwidth in the sense that it goes through the USB protocol. Depending on how many lanes in the USB C cable/connector it uses, it limits the USB bandwidth (USB 2.0 for 4k60p). So DP Alt mode is not limited to 10 Gbps, it can do full 4k60p uncompressed 4:4:4, also Thunderbolt 3 is not required, this is all in the USB spec. https://www.anandtech.com/show/85...-announced [edit: this is a more direct explanation: https://www.totalphase.com/blog/2...-c-cable/]

I myself am running RGB 4:4:4 4k 60p on a different hub.
