Awesome work. Having just gone through this for my company, I'd recommend a few valuable bits of information: - Thunderbolt 3 support filter - Power delivery capability (usually 60W-100W if at all) Both of those are valuable for mac shoppers.

I’ve got a carbon x (6th gen) and an iPhone X, I think what you want would work for me too. This is what I’m thinking of: https://www.amazon.com/Anker-Charging-PowerPort-Intelligent-... If someone happens to have experience with this, share your thoughts please!

If you're only after a power adapter for your X1C6 + iPhoneX then this Anker device will certainly work. I would however wonder if you really need 100W power, 75W would seem sufficient.

Edit: if you plan to use a USB to lightning connector for your iPhone X then indeed the 100W is needed as apparently this device splits power evenly (50W+50W) between the two USB C. A comment however says it's not fast charging the iPhoneX when they are both used, so now I understand your dilemma.

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.

This really didn't make things any less confusing. If anything else, I'm more confused by just a massive spam of product tiles as the first thing I see. It feels like I misclicked an ad in my Google search and ended up at a knock-off product website from abroad.

What you really need to be doing is making recommendations, product breakdown, and even label things as your "choice" and why. Right now, it just looks like a glorified affiliate link farm and that feels dirty.

Spamming users with a wall of product is not the solution.

Tangentially related, does anyone know if there is a DisplayPort-to-USB-C/Thunderbolt cable one could use to connect a GPU (DisplayPort) to a monitor (USB-C/Thunderbolt)? I'd like to connnect Titan RTX (DisplayPort) to LG's 31" 5k2k (USB-C) but all I see are cables for the opposite direction, i.e. USB-C/Thunderbolt to DisplayPort, for MacBooks. Other DisplayPort on LG is already used by another computer (gaming PC wi…

The Delock 63928 https://www.delock.de/produkte/G_63928/merkmale.html?setLang... is in the direction you want but I am not 100% it can do DisplayPort 1.4. AmazonGlobal ships it globally from https://www.amazon.co.uk/DeLOCK-Displayport-Adaptor-type-Mon... please test and report back either at https://www.reddit.com/r/UsbCHardware/comments/co23kd/i_have... and mention /u/chx_ so I see your report or just email me at ch…

Thanks, ordering that DeLOCK now! Will get back to you when I test it!

Titan Ridge is an option as well though I want to use it in an x399 Zenith Extreme board (DeepLearning rig) and that might be challenging (in theory it should work but the board is super buggy).

Looks like someone actually did manage to create a cheap adapter, and was able to power it from DisplayPort as well. I'd love to hear if anyone knows how well this works.

I'll see, I am worried it won't work as well as that LG monitor is like 1st gen bleeding-edge tech where incompatibilities might arise. MacOS users definitely had issues with it at first and those use USB-C connector on the display, but DP/HDMI works fine so far.

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

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

Because you said "preferably through USB-C".

Which of these would work best for connecting two external drives to move files around.

I have a 2013 macbook pro with 2 lightning ports, and 2 usb 2 ports.

Very often I need to connect two external drives at the same time, leaving me without a port to connect my wireless logitech mouse and keyboard.

I tried to find a lightning to usb adapter, but these don't seem to exist.

Thunderbolt docks with Titan Ridge controllers fall back to USB capabilities/bandwidth if connected to a USB-C non-Thunderbolt host.
