It depends on the configuration you're interested in, but there are some _relatively_ inexpensive ones from Monoprice [0]. I've tested this one with dual 4k monitors @ 60Hz, and USB 3. It works reliably, which is the most important aspect for me. No laptop charging and fixed TB cable however.

- horsawlarway 6y agoNote that this working will depend heavily on what usb-3 peripherals you're plugging in, and the exact resolution of your 4k monitors. a display at 3840x2160@60hz will eat up about 19.8gbps. Two of them together will use 39.6gpbs. Thunderbolt 3 only supports 40gbps. So if you have peripherals that need anything more than basic mouse/keyboard (in my case, a decent webcam and a usb to ethernet adapter) this setup will fail.
- dschuler 6y agoI'm no video expert, so correct me if I'm wrong, but I thought you can do 3840x2160@60Hz video with 24bit/pixel with under 14.4Gbps, which is the HDMI 2.0 limit [0]. According to this [1], that signal would require 12.54Gbps, so with a link budget of 34.56Gbps - 2*12.65Gbps, you'd have about 9.48Gbps left over for USB and ethernet (which is on the PCI bus for this particular hub). I suppose these numbers include coding overhead for the physical link, but I can't say for sure. If you wanted more than 60Hz or more than 24bit/pixel, you'd definitely run out of bandwidth with two monitors and USB/ethernet.
