I can plug in a X1 carbon thinkpad in my monitor (some ultrawide dell) with USB-C support just fine. I then get video, audio, USB (the monitor has a hub where I have mouse and keyboard connected) _and_ charging/powering my laptop over a single link. Works today with Linux here! It's just magical, I tell you. The world started to happen already, it may not become all that good and 100% universal soon or anytime, but g…

And if you plug a Samsung Galaxy S9/10/Note into that same USB-C, a full desktop will appear on your monitor as well using your existing ethernet, mouse, keyboard and audio outputs. Something not possible with full sized HDMI ports.

Great article. I was recently wading through this problem for my work setup. I was going crazy wondering what the actual technical limitations were with USB-C vs Displayport over USB-C versus Thunderbolt. I ended getting this WAVLINK dock for $150 with Thunderbolt 3. If you want Dual 4k montiors and USB 3 output + power for your laptop I recommend this. https://www.amazon.com/WAVLINK-DisplayPort-Thunderbolt-Charg...

I got one of these for just the 2 DisplayPort outputs: https://smile.amazon.com/Cable-Matters-Thunderbolt-DisplayPo... Then bought one of these from a coworker for $40 to drive all the other ports. I've been pretty lucky. (all being driven by a 2018 macbook pro) https://smile.amazon.com/Docking-Station-Laptop-Power-Delive... The first dongle is driving 2 Dell 23" 1080 screens, my 27" 4K screen is driven directly by a…

What they say is they have a charger in their pocket and connected to their phone while hiking. So they're like yanking the cable, sometimes slightly, sometimes harder, thousands of times per day, as they walk, climb, etc. I'd say put the thing in a backpack, or use wireless, or whatever...

I'd say it should be designed for being able to put a phone in your pocket while connected to a charger and engaging in sports. That sounds like a perfectly normal consumer-friendly feature, and consumers will do it anyway. Putting it in a backpack means you cannot easily look at it. The solution is fairly simple -- the /housing/ around the plug needs to be standardized and have a snug fit into the housing of the pho…

Not only that, but the USB-C plug itself is the worst-designed plug I have seen in a decade. It's flimsy sheet metal on the plug side with a nice big cantilever, and flimsy sheet metal soldered to a PCB on the other. Perfect recipe for broken ports and cables. I break about a cable a week and break a device every now and then. Mostly doing very normal things like charging a phone in my pocket while hiking. USB-C seem…

I've heard that USB-C is intentionally designed to break the cable rather than the port, in situations where one of those must break. That's absolutely been true in my experience. It doesn't happen often, but I've dropped two phones while they're charging onto the cable. The micro-USB phone never charged the same again; depending on the cable, you needed to put pressure on it to tilt it in the right direction. My new…
