Allsmartlife USB C to Mini DisplayPort Adapter, USB Type C to Mini DisplayPort/Mini DP Adapter Cable with Aluminium Case Support 4K Resolution for Apple New MacBook, ChromeBook Pixel

This product: "ALLSMARTLIFE" - USB C Type to Mini DisplayPort/Mini DP Adapter:** Yes this competitor's product that looks the same DOES work for me as follows: **1. From my MacBook Pro 2017,2. Using this USB-C/Thunderbolt-3 to Mini DisplayPort adapter,3. Into my Apple Dual-link DVI / Mini DisplayPort adapter,4. Into my 30" Apple cinema display.I see no flickering and no problems, it works fine.Competitor I tried "ITD ITANDA" - USB-C to Mini Displayport Adapter** No this does NOT work for me as described above, as follows: **I get nothing but artifacts and fractions of a second of what's on the screen.UPDATED 6/3/18 - NEW THEORY:"ALLSMARTLIFE" (this one), uses "active" chip/output which WORKS with the Apple Dual-Link DVI Mini DisplayPort (fw1.3) adapter's input."ITD ITANDA" (competitor), uses "passive" chip/output which is INCOMPATIBLE with the Apple Dual-Link DVI Mini DisplayPort adapter's input.I found out through a ton of googling that if the cable and adapters are not "active" then things seem flaky at best or just don't work at high-rez.Yes, in both tests of both adapters.. I have the USB Type-B Tail which is is the power connector for Apple's D-DVI -> MiniDP adapter plugged into a high-power USB, without it plugged it then nothing comes on at all (that's the Apple adapter's "power cord" so to speak)..Note the Apple 30" cinema display resolution is 2560 x 1600, which is within (less than) the published max resolution specs of this USB-C/ThunderBolt-3 to Mini DisplayPort adapter which DOES for me with This ADAPTER (NOT others that I tried).!!IMPORTANT!!: I believe I know why some reviews say a particular double-adapter effort like this works for them, and some say it doesn't; I think it's because there were at least 3 revisions of the Apple Dual-Link DVI to MiniDisplayPort adapter, with firmware versions 1.1, 1.2, 1.3, that you CANNOT upgrade through software. I know this first-hand as I originally had glitches with the Apple D-DVI to MiniDP adapter on my old Apple 2010 MacPro Xeon with firmware 1.1, but Apple physically exchanged for another free with the 1.3 firmware built-in to fix my issue at the time. TO BE CLEAR, I HAVE THE APPLE 1.3 FIRMWARE VERSION THAT IS WORKING WITH THIS "ALLSMARTLIFE" ADAPTER..So, long story short, if you go into your Apple Mac's display details, it will show you the firmware version of that Apple D-DVI to MiniDP adapter, and if you have firmware v1.3, then I can this one DID work with this particular USB-C/Thunderbolt-3 to MiniDP adapter-to-adapter from a MacBook Pro 2017, whereas others failed.Thus if this does NOT work for you as I described, then:1. Check your Apple Dual-Link DVI to MiniDP adpater firmware in your Mac's computer details, and2. If it's not firmware v1.3, then bring it into a Apple store and ask them to swap it free!3. (search for it, there is an Apple article offering this trade-in to v1.3 firmware for free without receipt and no matter when you bought that Apple adapter).Hope this helps someone out there to avoid frustration wasting $20 or get scared by guessing......

After steeling myself for dongle hell I bought a higher-end 13" 2018 MacBook with 4 USB-C ports. After realizing there was no USB-C to Dual-Link DVI adapter to connect to my ASUS monitor at 2560x1440, I got everything working just fine with the help of this adapter. Here's my set-up:- This USB-C to Mini DisplayPort adapter- Apple Mini DisplayPort to Dual-Link DVI adapterhttps://www.amazon.com/Mini-DisplayPort-Dual-Link-DVI-Adapter/dp/B0751RL35H/ref=sr_1_3?ie=UTF8&qid=1540172588&sr=8-3&keywords=apple+mini+displayport+to+dual-link+dvi+adapter- Apple USB-C to USB adapterhttps://www.amazon.com/Apple-USB-C-to-USB-Adapter/dp/B00VU2OID2/ref=sr_1_1?ie=UTF8&qid=1540171605&sr=8-1&keywords=apple+usb-c+to+usbNote: this Amazon Basics one is $10 cheaper and probably the better choice:https://www.amazon.com/Apple-USB-C-to-USB-Adapter/dp/B00VU2OID2/ref=sr_1_1?ie=UTF8&qid=1540171605&sr=8-1&keywords=apple+usb-c+to+usbThe DVI adapter requires two connections: DisplayPort for video and another USB connection for supplemental power. Along with my laptop input power that's 3 ports total - I'm glad I chose the 13" MBP with 4 ports instead of 2. If you have a 2-port MBP you'll need an external USB power hub for the supplemental power.Side note: I was tempted to go with the 2 port MBP to avoid the Touch Bar, since I like having an escape key. I decided to tolerate the Touch Bar in return for 4 ports when I discovered that it's possible to "remap caps lock to escape and control" - the Caps Lock counts as Escape if it's tapped on its own or Control when used with another key.

Unfortunately, this adapter does not allow you to connect a DisplayPort monitor (e.g., ASUS PB278Q) to one of the newest Apple computers (e.g., 2017 Macbook Pro). I don't actually understand why, and it's not clear whether the blame for this not working lies with Apple or with AllSmartLife. One thing that is clear is that the USB-C ports on new Apple machines are actually Thunderbolt 3 ports. Both USB 3.1 and Thunderbolt 3 use USB-C connectors. So maybe there is some protocol mismatch happening here. I was under the impression that Apple machines would "do the right thing" even when USB devices were plugged into the Thunderbolt 3 ports, but maybe not. Anyway, this thing does nothing for me. Annoying.

Recently updated my laptop to the new MacBook Pro that only has USB-C ports. Geat new technology, but none of my old cables work anymore. I have a trustworthy 27" Apple Cinema Display that I have been using for many years, and I can continue to use it with my new laptop and this adapter.It works great, same great picture quality and color accuracy. I am a graphic designer, calibrating my monitors and color are very important to me. No lagging on time either when connecting the laptop to the monitor.I highly recommend this product.

I have seen a few reviews that comment on using this with the New MacBook Pro w/ Touch bar and it not working. I bought it in the last effort to salvage using my 27" Apple display. I am happy to report that this allows me to continue using monitor and works great. I would have given 5 stars, but the cable between the usb-c and the housing is a little flimsy. Should not be a problem for me as this will be attached to my monitor and not taken with me daily. This devise does what it says and passes the display port data to the month with out a problem. So if you have an old Apple display, this will allow it to remain in service with the MacBook Pro. Hope this review helps.

This adapter does exactly what is needed.I purchased a new laptop (Dell XPS 13 - 2016 version) which has a thunderbold 2 port. I needed to convert this to a mini displayport output to be able to connect it to my external monitor set up. This device works perfectly.In fact, even though the description on the website doesn't specify that the adapter is mini displayport 1.2 compatible, it is.
