Re: Explaining 4K 60Hz Video Through USB-C Hub
#2Interesting! Was wondering about this recently when shopping for a USB-C hub, and couldn't find many that supported 4K@60hz. Ended up getting one that does 30hz because my Display at home is only 1440p.
I have used Displaylink adapters before (have one floating around somewhere), and was not super impressed (my machine was a bit flaky when using it), although I did have 2 external displays going on my Macbook at one point (this was before the days of multiple Displayports on Macbooks), which was kind of fun.

#3I wish I had come across this article when I was looking for a dock for my MBP (connected to a pair of 4k monitors). It was a pain to try and figure out if I'd be able to get 60hz video from a particular docking station. I went with the Caldigit one and luckily it worked. It's nice to learn why.

#4I'm actually a bit confused by why it matters at this point. HDMI is ubiquitous, can handle a high enough resolution/ rate that most human eyes can't distinguish better, and is relatively cheap. It's an optimized, widely available format, and does a great job. USB is a downgrade for this particular task. Other than novelty, I don't see a reason to ever do this.

If I were to guess, I would say it comes down to the U in USB, and power delivery.

#6Entertaining read. What a blunder the USB group has made with v3.x, it’ll all work out and eventually be awesome when every port and every cable just works and things charge fast but, almost every major feature of USB has had issues going back to first release. More reviews and articles should have a liars section.

>can handle a high enough resolution/ rate that most human eyes can't distinguish better
Could you specify which resolution and refresh rate that is? Are we still talking about 1080p or this is higher?

#8The HP ZBook Dock with Thunderbolt 3 tends to be on ebay for around US$50 and should do 4K 60Hz.

What do you mean? Plenty of computers now ship with no other connectors than USB-C. In other words HDMI is not ubiquitous
What I love about USB-C is I plug in a single cable to my laptop and I get keyboard, mouse, wifi, and monitor (4k 60hz)
At work I have a USB-C hub for my one cable to my computer. The hub has Displayport so I can use HDMI on a different device. At home my monitor does USB-C natively so my keyboard and mouse are plugged into that.

#10re "Driver availability and compatibility for Mac/Linux is spotty to non-existent":
Is it true that DisplayLink doesn't work well with Linux? Some years ago people were saying that the usb-to-monitor dongles worked well. A casual web search also gives this impression, with good support provided by the DisplayLink company.
