USB 3.0 Universal Laptop Docking Station, Dual HDMI Monitor

I don’t normally write reviews because like everyone else on this planet I’m busy, between my graduate degree, work, and life in general, my spare time is valuable. However, I struggled for months trying to find the right combination of things for my specific situation and I am hoping this will help other people make an informed decision that they are happy with. After talking with tech people at work and in stores, and in addition to my own internet research I finally settled on the Plugable USB 3.0 Docking Station (Model UD-3900, Dual Monitor Docking Station).I’ve included my thoughts on the Plugable USB 3.0 Docking Station as well as some helpful hints that users who are not super computer savvy might find helpful (I will add, I’m not a super techy person myself).First, my thoughts on this product:It accomplishes my “wish list” without having to spend hundreds of dollars on a Docking Station.I have two computers – an older, personal computer (from around 2013/2014 time frame) that does not have a 4K screen and a brand new 2019 screaming machine that is provided by my job that does have a 4K screen. My home monitors are two 27” LG Class Full HD IPS LED with dual HDMI connections that I purchased around 2 years ago. This means that I am dealing with resolution differences across all of my equipment (I’m working with 3 generations of technology). Each computer has the following connections – 1 HDMI port (both computers), 3 USB ports (older computer - 1 USB 3.0 and 2 USB 2.0), 2 USB ports (newer computer – all USB 3.0) and 1 USB-C Port (newer computer).My wish list included the following:1. Connect and EXTEND my desktop display to my two 27” monitors.2. Keep a resolution that does not blow everything up to a size that is unusable (an issue when dealing with 4K and not 4K capable equipment)3. Plug one cord into my computer (rather than multiple)The Plugable USB 3.0 Docking Station does exactly this with minimal effort and without spending hundreds of dollars. I was really pleased when I plugged everything in and changed the display setting to extend and everything just worked. (As a note, I did tinker with the resolution settings on both computers to get my mouse to move screen to screen anywhere along the side borders – I did not observe a noticeable change in the image on my computer or on the monitors after doing this.) I was fortunate that all I had to do was plug and play and did not even have to restart either computer after plugging the unit in for the first time. The little informational booklet that comes with the product is actually pretty helpful if you know a little bit about what you are doing and want to accomplish, though it is brief and mostly contains pictures. There is also a web page and email address listed in the booklet if you need troubleshooting help. In short, if you have lots of cords that need to connect to your computer (for whatever reason), you don’t care if it charges your laptop, and you need two additional displays I would definitely recommend this docking station.Here are some things I learned along the way in regards to my specific situation. This is not meant to be a how to for all systems or set ups, just information that hopefully helps others. There is a lot of functionality in this little device way beyond what I have covered below - again, I'm not a really tech oriented person, a lot of what follows is laymen's terms.1. Calling this a “docking station” is a bit of a misnomer – a true docking station, when plugged into your laptop, will charge it (this product does not charge the device it is plugged into). True docking stations also have a multitude of other capabilities, including supporting more than 2 screens and device charging and will run you in the $200 - $400 range. I would dub this a “docking station Jr.”, some but not all of the capabilities of a true docking station. That being said, it does have the option to plug in an Ethernet cable to it, thus eliminating an additional cord attached to your computer (super convenient!). I’m all about fewer cords if possible and if you have to be hard wired into your internet this is definitely a plus.2. The order of the monitors (1, 2, 3) is as follows on the back of the Plugable USB 3.0 device (keep this in mind if you are picky about how your mouse will travel from one monitor to the next)a. Monitor 1 will always be the device you are duplicating or extending by defaultb. Monitor 2 will be the DVI portc. Monitor 3 will be the HDMI port3. Cables…there are so many choices and some are directional and some are not and some need adapters and some don’t and, and, and… jeepers cats batman why can’t this be more simple!!! Here’s what you need to know about your computer and monitors to make THIS PRODUCT work.a. Do you have a USB 3.0 Port on your computer? It will say SS (super speed) next to the port. Most new computers have at least one USB 3.0 port, some older computers, like mine have 1 USB 3.0 and 2 USB 2.0. I recommend using the USB 3.0 rather than the 2.0. The basic difference is in the speed of data transfer, but either should work according to the box. (I did not try using the USB 2.0 since I have a USB 3.0 available on both computers.)b. Does/do your monitor(s) have any of the following ports on the back – HDMI, DVI, D-SUB (also sometimes called VGA)? I don’t recommend using the D-SUB (VGA) port, it doesn’t support very good resolution and you may end up with a really grainy image on your screen, but in a pinch it functions exactly as it is designed to with an adapter to connect it to the docking station (the unit comes with a VGA to DVI adapter if you didn’t notice in the product description). You’ll need a DVI to DVI cable if you are going to use the adapter.c. IF YOU HAVE HDMI PORTS ON BOTH YOUR MONITORS - here are the cables you should buy:i. 1 HDMI to HDMI, spend a couple extra dollars and get a decent cable, my experience with cheap cables is they are well, cheap. The connection can be flaky and they just give up the ghost randomly leading to the purchase of, you guessed it, another cable.ii. 1 HDMI to DVI, again spend a couple extra dollars and get a good cable.d. You need to have at least one monitor with an available HDMI port for this docking station to work for TWO MONITORS. (Why, because of the type of connections available on the docking station and the way display data is designed to stream through the available connections on your devices – there’s a way more technological answer, but simply put 1 connection out on the docking station gets you 1 connection in for each monitor.)e. What direction should the cables be connected??? This relates specifically to the HDMI to DVI cable. The DVI side of the cable is the signal out; plug it into the docking station. The HDMI side of the cable is signal in; plug it into the monitor. You are moving the image from your computer/docking station (out) to the monitor (in).4. Duplicating a desktop vs extending a desktop:a. Duplicate means just that, whatever is on my desktop will be on my monitor(s), if I move my mouse on my desk top it moves on my monitor(s). Think meeting in a conference room where someone puts their computer screen up on the conference room monitor for everyone to see – duplicated.b. Extend means take my desktop and stretch it out across all three monitors. (Tricky, now you see where resolution problems can come into play.) For my set up my laptop is on the far right, monitor 2 is in the middle and monitor 3 is on the far left. This means that if my mouse starts on my laptop (far right) and I move to the left border my mouse will “exit” my laptop screen and “enter” my monitor 2 screen on the far right. The same will happen when I move from monitor 2 to monitor 3, and the reverse will happen when I move back towards my laptop screen.c. There a literally hundreds of YouTube videos on how to duplicate or extend your screen, simply look up “extend my computer screen” on YouTube to learn more.5. Resolution – tricky stuff if your equipment is all different like minea. Ever notice how when you go to arrange your screens in the order you want and some are pictured big and some are pictured small? This is because of the resolution that is set for each screen. This also means that you have to remember how you set up the order of your screens - where the borders touch in picture in the settings is the ONLY PLACE THE CURSOR CAN MOVE FROM SCREEN TO SCREEN.b. Normally the “recommended” resolution is sufficient. If you have a variety of equipment you may need to tinker with these settings. I don’t have a good step by step option because everyone’s equipment is different, all I can say is experiment; you can always change it back later. YouTube is another good resource for where settings are located and how to change them.c. If you want all of your screens to be the “same size” in the settings so your mouse can move from one screen to another at any point along the border you’ll want to set the resolution for each screen in the settings to the same thing. This might mess with how things look on your monitors and on your computer, again, tinker with it, you can always change it later if you don’t like it.Again, this is not meant as an official “how to guide”; I wanted to share some of the things I learned and clarify some terminology for those who are not super tech savvy. Hopefully this helps someone who is trying to decide if this product is the best option for their setup. Happy Computing!

I've had this since October 2014. This is a great dock, way cheaper than a lot of other solutions. I got this dock mainly to connect my Surface Pro 1 and 3 to it. Both have docks specifically made for them by Microsoft, but for the Pro 1 it was extremely expensive for not many ports. For the Pro 3, there are a lot of port options, however the dock itself has bugs and is finicky.Firstly, I like the fact that when you first buy it, they email you with some instructions to where to download drivers and stuff so you could get your computer/device ready for when the unit arrives. I got that done with no hassles, then the unit comes in 2 days later with prime shipping.Installing it was a cinch, just connect power and all the stuff you want connected to it. For me, I connected 2 monitors to it. The unit has 2 outputs for video, one HDMI, and the other is DVI. Connecting them was pretty self explanatory. I also have a logitech wireless mouse connected.Once everything is connected, you just connect the USB cord to your device. For the first time it does this setup thing and detects your displays and asks you to adjust the monitors as you deem necessary. After that, every time you connect it, it just works.I have no problems with it whatsoever, and it work pretty much every time. You can have one or both monitors on if you want. I have it connected so that the Surface itself is a screen and the other 2 monitors extend the desktop, so I essentially am running a 3 monitor setup. There is not noticeable lag that you see with USB 2.0 docks. The one thing is that you have to turn on your computer/device before you connect it. For some reason, if you connect it first, then turn on, it just stays as a black screen. You'll then have to unplug, then plug it back in for it to work. As long as you turn it on first, then it's fine (you don't have to unlock it first either). As soon as you unlock it, it detects everything and just starts up like how you left it before.Other than that, I don't have any complaints. It's small, has one USB charging point for when nothing is connected which is nice. I would be nice if it also charged my Surface like the official dock, but since this is universal it's fine. I can use this with any device fine. I did have a Sony Vaio Pro 13, and it also worked flawlessly with that when I had it.
