I wouldn't trust Dell with this. I have a Dell monitor that I bought because it has a USB-C port that supported both PD and video. But it turns out it doesn't work well with MacBooks (constantly loses connection, and messes with the MacBook's sleep). Dell acknowledged the issue and released a patch that fixed it ... for Windows machines. They refuse to fix it for MacBooks because they don't want to support a competit…

What model monitor is this?

It's a Dell U3818DW

I want a USB-C hub that's just one USB-C in to multiple USB-C out. Why is that so impossible to find?

Type-C says that there can't be type-c hubs. Just wait for some Chinese OEM to work that around

Why do they restrict this in the spec? Doesn't that just encourage people to use USB Type C to USB-A hubs, making adoption to Type C slower?

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…

I don't think they'd bother, because none of these docks can do it. USB-C 3.1 inherently can't support a 4k@60hz display, due to bandwidth limitations. And it certainly can't run two of them. You'd have to jump up to a Thunderbolt 3 dock for that sort of thing.

I like wirecutter for this. Their picks are rarely the most expensive and they try to recommend things that last long. I am happy they can make a dollar or two of my referral link pick for the research work they do.

I've had very bad experiences trusting reviews of the wirecutter for some products that were obviously inferior to alternatives after returning and purchasing alternatives.

I started getting suspicious of The Wirecutter when they reviewed bike racks and concluded that the best kind is the type that attaches to the trunk lid with hooks and straps. To anyone who has carried a bike on a car more than once, it's obvious that these are the worst kind, by far. But they are also the cheapest, by far. It's like saying that the best computer to buy is a $300 Chromebook, and it makes me question their judgement on all products.

The Thunderbolt capable docks on Amazon are still listed as USB-C because consumers seem to think it’s all about cable shape. That said, there are plenty of dual USB-C connector, dual HDMI 4K@60hz port, dongles designed for Mac on Amazon. I think this is the most recent addition: https://smile.amazon.com/gp/product/B07RH9HF4R/ ”Satechi Aluminum Type-C Dual HDMI Adapter 4K 60Hz with USB-C PD Charging — Stunning dual H…

As others have noted, the Thunderbolt/USB landscape is pretty confusing.

This is great. I always wonder why amazon itself is so useless in this space. The only thing you can go is price and reviews there, without any good comparisons between products.

I like wirecutter for this. Their picks are rarely the most expensive and they try to recommend things that last long. I am happy they can make a dollar or two of my referral link pick for the research work they do.

As a heads-up, this means that if the best product isn't available on Amazon and the other site isn't willing to pay a commission to them, then you won't hear about it.

An example of that is nextdesk: https://www.reddit.com/r/StandingDesk/comments/69npx4/drama_...

Sorry, to clarify, you technically can get enough bandwidth for 4k@60hz out of a USB-C port, but you have to abandon the data lanes for more DisplayPort lanes. (I.e, give up all of your USB 3.0 ports and gigabit ethernet or similar-speed ports). So, "adapters" can do it, but docks generally can't. https://www.bigmessowires.com/2019/05/19/explaining-4k-60hz-... has the specific technical details.

That‘s not generally true. Apple‘s newer model multiport adapter does 4k60 and USB 3 on devices supporting DisplayPort 1.3 (which is required to fit 4k60 into two instead of four lanes).

That's the magic of displayport for you. It won't do that on HDMI, except with active converted from DP to HDMI :)
