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.

Interesting; I have the S9 and I've done this by accident while charging, but the monitor only shows what's normally on the phone screen, it doesn't stretch to a "full desktop". The mouse does work though.

Is there some setting I need to enable on my phone, or is my setup just different in some way?

USB-C allows me to hook up my laptop with one cable. Your middle-ground standard wouldn't.

Where I work many people have a docking station with a USB-C plug and a power plug molded into one connector. One cable to plug in, can safety deliver more power than USB-C can alone. With a bit of work engineers could have standardized an expandable cable. You have your basic USB-c cable with one fast (display port?) lane, one usb-3 data lane, the - basic cable in the article, enough for phones and light use. Then t…

What happens when you get a laptop with a slightly different port arrangement? Just throw out all the old docks? Seems like quite a solution from a manufacturer's perspective!

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…

It is a little bit warm, but nothing concerning. I can leave my hand on it no problem.

The USB-C spec is an insane mess. The fact that every port used to be different is actually a feature, as it helps you identify which device supports what based on the ports it had. If you see an HDMI port on a laptop you can be sure it's going to output some kind of video signal over that. If you see Thunderbolt then you're sure the machine supports Thunderbolt. USB-C just jams all these incompatible standards into…

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 USB-C phone cleanly bent the cable, and the connection seems as solid and as reliable as it ever was with the replacement.

> I break about a cable a week and break a device every now and then You're doing it wrong then. I have about 5 USB-C cables and have never broke one in 3 years... Kinds of cables I have broken over my IT life: - A few Apple charger cables (on the Mac connecting end) - A few headphone cables

I disagree with the notion that just because they break that I'm "doing it wrong". Please listen to the customer. Rather, I'd say that they're just not rugged enough for my (consumer) standard of use, which needs to be more rugged than office use. I have legitimate needs to engage in sports while devices are plugged in and accessible. Other consumers get stuff bitten by children and pets, stepped on, tangled, and cau…

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…

Once this is sorted out we would have a wonderful world. Using a single Thunderbolt port I connect my notebook to a dock and immediately convert the small notebook into a desktop with three external monitors plus many other ports. I can also magically use the same USB-C hub I use in the notebook in my mobile phone to add a keyboard and mouse plus an HDMI monitor. I have never seen this in the past: my previous notebo…

Has anybody yet made a GPU and monitor that use a type-c alternate mode (whether it be display-port or something else) plus power delivery, such that your monitor does not need a separate power cable?

I would love to reach the point where a desktop computer only had a single power cable leading to the wall, with everything else getting powered via it.

I like the intent, but I would prefer ruggedizing them to the extent that neither of them breaks. Many automotive connectors, for example, are both inexpensive and extremely difficult to break either.

I also recently bought a monitor with USB-C (Thunderbolt 3) which I can plug it's single cable into my DELL XPS and charge it, output 4K@60 to the display, and have my mouse and keyboard which are connected to the back of the monitor. The downside is when I want to use the same kb/mouse with my desktop, I have to unplug them from the monitor and plug them into the desktop.

The new Dell monitors have built-in KVM-s for exactly your use case. https://www.dell.com/en-uk/work/shop/dell-ultrasharp-38-curv...
