Hello guys,

I'm searching a dock capable of handling 3 x 4k screens at 60fps. I found this one which handle MST https://satechi.net/products/thunderbolt-4-multimedia-pro-dock

What do you think ? Will it work well over one USB C cable

Thanks

No, probably not, not with AMD.

I'm not sure to understand it, can you develop in details why it would not work please ?

Satechi does a terrible job of specifying what this dock can and cannot do.

But they advertise it for 2 screens on Macbooks, which means it will very likely built like the Plugable https://plugable.com/products/tbt4-udz.

And that dock needs 2 separate DP connections via TB in order to drive all 4 display outputs.

And AMD's USB4 implementation only offers a single DP connection, not 2, so only half of the ports can be active at a time.

So if I understand correctly, the other dock linked (the lenovo one) will work with AMD TB4 and 3 screens, since all screens are on the same MST.

Is that correct ?
