Needs to filter whether it can show HDMI 4K at 30Hz or 60Hz. And related to that, for video, it’s possible to have 2 4K 60hz through or one or none. Also filter whether it’s one USB-C connects to computer or two USB-C connects to computer. With two USB-C connected to computer, can pass through more types of USB to accessories. Finally, it doesn’t show matches that I know are matches. // I buy these to test, but don’t…

A much more concise but similarly deep intro can read at the beginning of https://www.reddit.com/r/thinkpad/wiki/newdocks

I'm in the market for a dock/hub for my 16" MBP and I'm completely baffled by the lack of decent options. I just want the following 3 capabilities: - 100W PD - 4k60Hz (preferably through USB-C) - Gigabit ethernet I have not been able to find a _single_ docking station or hub that can check these 3 boxes :(

4k60 + gigabit is not possible without going up to Thunderbolt 3 - there isn't enough bandwidth otherwise. The best you can do is 4k60 + USB 2.0 (so a gigabit Ethernet connection would cap out at ~300mbps in practice.) See https://www.bigmessowires.com/2019/05/19/explaining-4k-60hz-... DisplayPort 1.4 changes this, but everything seems to be stuck on 1.2 100W is, of course, possible. I use a CalDigit USB-C Pro Dock w…

How does the CalDigit TS3 Plus do it then?

Too bad about the 85W.

I know you're right, but nowadays, everybody calls them hubs. But if you really need the hub you describe, here's one that I think conforms to what you describe: https://www.coolgear.com/product/usb-31-typec-4-port-hub-or-... For a little bit more, you can have 6 USB-C ports: https://www.coolgear.com/product/usb-3-1-dual-type-usb-c-a-8...

Could I connect my mbp to this with one cord to get power and external monitors?

It connects to your computer via USB 3.1 and a USB type-a port. Unfortunately type-a can't power the computer and can't carry video signals.

Anyone else thinks its weird that we created an entire industry/product section just because notebook builders don't include common ports anymore?

Not really. I mean, it's conceivable that portable devices have gotten smaller and more streamlined since they get replaced sooner, while the outside world has largely remained the same (from a connectivity standpoint).

It uses Thunderbolt 3. Same connector, but different protocol with 2-4x the bandwidth.

Personally I am CalDigit fan and if 85 W are good enough: https://www.caldigit.com/ts3-plus/

I'm reluctant to spend that much if it can't even fully power my laptop.

I fail to see why you assumed I wouldn't want a thunderbolt 3 dock.

I just want to tell you how much I appreciate how you allow to turn the affiliate link on and off. And also that you basically made it so that it's the first thing I see when I join. I don't see that much honesty and openness out in the open that often. So thanks!

It looks really nice!

I was wondering if you could add power output per port, and total, in Amps...

Reason that I ask is because someone might want to power a whole bunch of Raspberry Pi's off of a single USB hub, and if it doesn't have the requisite amps (~3.0 Amps per socket), it will probably burn out, or power will probably sag, and that wouldn't be fun!

But, other than that minor "would-be-nice" -- great site, all in all!
