Dell Adapter-USB-C to HDMI/VGA/Ethernet/USB 3.0 (DA200)

I tested this with a new 15" MacBook Pro (late 2016) with TouchBar, running macOS Sierra 10.12.1 as factory installed. I had little confidence in Dell from prior experience and from other reviews here, but I have to say that this product worked wonderfully without any drivers required, and has a great form factor. Below I give details of the function of each port without drivers, and then after installing DisplayLink drivers.* Gigabit Ethernet:After plugging in, shows up as "USB 10/100/1000 LAN" in network devices. I tested throughput in both directions using iPerf and confirmed full gigabit performance. I burned it in during all tests to see if warm-up would cause speed loss, but throughput remained constant at gigabit speeds.* USB3:Tested performance with external SSD, and compared throughput to direct connection to computer. All speeds the same and at USB3 throughput.* VGA:Worked upon connection, tested to 1600 x 1200 at 60Hz.* HDMI:Video worked upon connection, tested to 1920 x 1080 at 60Hz. However audio over HDMI did not work (on a cable that I separately confirmed passed audio).At this point I had everything I wanted, but I decided to try installing the latest DisplayLink drivers from their web site to see if it would fix the audio over HDMI problem (I read that audio is passed over DisplayPort protocol). Installed version 3.0 Beta 1 (1 Dec 2016) and indeed it fixed the audio problem. I note that the driver package also comes with an uninstaller.I wanted a small adapter I can carry with my small computer case and have quick access to these 4 specific ports I encounter daily going to different rooms, different sites, and to secure or underground locations which have wired ethernet only. This adapter fits the bill perfectly. I did not experience any of the problems some other reviewers mentioned about the order of connections making a difference. Note that when you install DisplayLink drivers, it will also silently update firmware on the adapter itself if out of date. On mine I looked before and after with System Information and saw no differences, but for users here with earlier firmware versions, this might explain some of the observations others have seen with driver interactions. In conclusion, for this system, if you don't want to install any drivers, you will get all 4 ports working with communication and video. If you additionally need audio over HDMI, the driver fixes it.It is pretty ironic this Dell adapter works nearly flawlessly with a Mac that was just released, and can't even work on Dell computers that have been around for some time. But I'll take it!-----Update March 2019-----Still working and works great on 2018 15" MacBook Pro too.

Verified with new Macbook Pro Late-2016 w/o touchbar.I was hesitant to get this because of so many bad reviews, but I was encouraged by the good reviews from all Mac users.I can verify that all four ports work on my fresh out of the box Macbook Pro without installing any drivers.The design of the device is perfect. It is very compact and the cable tucks away completely into the device so you have a smooth bar that's easy to stow and does not snag on anything. The cable is very flexible silicone and feels very nice. I really just needed the ethernet and maybe the USB-A, but this device stores smaller that even a single adapter. So if you have a Mac, get this versus even a single dongle and you will be covered for anything.VGA Port:I thought I would need the DisplayLink driver at first because I could not get the VGA port to work, so I installed the driver. I still could not get the VGA port to work. I tried some re-plugging and it seems like it works when the VGA is inserted into this device before connecting to USB-C. Not sure if that is the only way to get it to work, but that definitely fixes it every time for me when I have a problem. Once I do get it working, I haven't had it quit. Just to be complete, I uninstalled the DisplayLink driver and confirmed that it was wiped out and everything still works fine.HDMI Port:I never had a problem getting HDMI to come up whether I plug the HDMI first or the USB-C first.I have a TV that will take either 720P, native 1360x768, or 1080P. I was able to switch between all three resolutions without a problem.Ethernet Port:I first had some issues with the ethernet port like the VGA. Didn't find a pattern, but re-plugging and some jigling got it working. I am able to connect at gigabit full duplex.USB-A Port:No problems here. I didn't have a USB 3 device handy so I only did a transfer with a USB 2 thumb drive.MacOS reports as a USB 3 port.So I got everything working without any drivers. In hindsight, the connection problems I had may be due to the seating on the USB-C side. I did notice that the connecter on the device is the cheaper type where the outside ground is a stamped sheet that is bent around and joined instead of a single extruded piece. It is possible that a few insertions were needed shake off any oxidation to start making a good connection. I will update after some use if I continue to have problems or not.I take a star off for those issues, but they are minor. If this is reliable over some use, I will definitely upgrade to 5 stars.March 2017 Update:Have used this for a while now. VGA is still best if connecting VGA first and then plug in USB-C.VGA use is almost drying up. Mostly using ethernet and HDMI. USB-A is also very occasional now.Have not had any problems. Upgrading to 5 stars.

Very compact and lightweight, provides exactly what you need if you do things like teaching or conference speaking, without worthless stuff like SD-card slots. For some reason, it's hard to find an adapter that seems to have speakers in mind. The network port is particularly welcome---conference WiFi is always miserable, so being able to plug in is essential, and you have both VGA and HDMI for your video and a USB-A port to plug in the dongle for your remote presenter. Works well on a macbook pro (though won't work for a plain-old-macbook because there's only one USB-C port on that particular machine and there's no power pass-through on the adapter. You'd have to run off of battery power for the whole presentation. The Macbook Pro has multiple USB-C ports so you run on AC power while using the adapter). The only downside is that the build quality isn't as good as I'd like---doesn't fill me with confidence. We'll see if it breaks down, but I"m also carrying one of the Apple USB-C/HDMI adapters as a backup just in case (it will be annoying to lose the ethernet if I have to go to the backup adapter, but at least the show can go on.)
