Style Name: USB 3.0Size: Triple Display Verified Purchase
Well, I have been using one of these docks for almost a year now, and I have been extremely impressed. The picture quality is great, and the functionality is very reliable. I do, however, have two complaints.

Firstly, the setup is not as simple as it should be. There is firmware available on the Dell website, as well as on the DisplayLink website, but no native software application for managing the displays once installed. You are forced to use the Windows display management software, which is absolutely not user friendly, especially if you are running triple monitors or more. It takes some time to get everything set up and working properly, but once you get it done, you should not have any further issues.

Secondly, this dock has a DisplayPort output. If, however, you own or intend to purchase monitors, like my three Dell U2414H flat panels, with MST (Multi-Stream Transport) capability (aka Daisy Chaining) you will be disappointed to learn that this dock does NOT support MST. Rather than connecting multiple monitors to one display output, you have to run a separate video cable for every single monitor. What's worse, the dock only has one DisplayPort output, the other two outputs are HDMI, so if your monitors came with DisplayPort cables like mine did, you will have to buy additional HDMI cables as well...

None of these issues is a deal breaker, and now that I am set up, I am EXTREMELY happy with the end result, but just a little bit of info I wish I had known prior to making my purchases.

Style Name: USB 3.0Size: Triple Display Verified Purchase
I am so glad I got this!

I have a Dell laptop for work that clicks into a (Dell PR03X) docking station. I hate the docking station. It's just difficult to get the laptop connected to it and the docking station only allows for 2 extra monitors, not 3. So I had to buy an external USB video card for my 3rd monitor.

I purchased this as a replacement for my PR03X dock and it's an EXCELLENT replacement. For one thing, I can use it with all my laptops, not just my Dell. I have a Lenovo Yoga (my wife's), a Macbook Air (2011 with OS 10.9 - which required the software from http://www.displaylink.com/support/mac_downloads.php), and my work Dell laptop. All 3 work great with this little hub. And it is pretty small and lightweight.

Note: I wasn't really sure how this was going to connect to my laptop(s). It turns out it connects via a typical USB (2 or 3) port. My Macbook Air has USB 2, while my Lenovo Yoga has USB 3.0. Both work flawlessly. However, obviously the extra USB ports the device provides won't operate at USB 3 speeds if you're connected to your laptop via a USB 2 port.

Anyway, once you've connected the doc to your laptop (or desktop) via a USB 2 or 3 port, its ready for up to 3 monitors to be connected to it. Two via HDMI and a third via Dell's DisplayPort (which you can get a DisplayPort-to-HDMI adapter if needed). So with the laptop screen this gives you a total of up to 4 displays!

The One Con:
It seems like video playback might be a little choppy when watching a 1080p video clip on YouTube while connected to a USB 2 port. I'm not sure if this was the internet or a FPS limitation of the USB video throughput. However, it seems to playback video flawlessly using a USB 3 port.

I purchased this dock with the mind that its not for video processing/video playback or gaming(but, I'm able to have two 1080p video's running on different screens with no issues.)

This type of box makes it easy for telecommuting, when all I need to do is connect a single USB 3.0 cable to my laptop to connect everything up (and makes it easier to switch to my own personal laptop at the same time)

I am using three monitors @ 1080p for each monitor.

Bad thing I just found: Audio - I couldn't just plug in a set of speakers (Wouldn't detect) and had to use a splitter cable to allow me to plug in regular speakers. I used the following one and it worked fine for audio out - StarTech.com Headset adapter for headsets with separate headphone / microphone plugs - 3.5mm 4 position to 2x 3 position 3.5mm M/F

I bought this dock to set up my 3 monitors on my desktop. It works GREAT! I read some helpful reviews prior to making this purchase. A previous reviewer stated that you should run the software setup disc on your computer before you hooking up the monitors to avoid troublesome setup issues. I did this and the installation was flawless.

The only issue, and the reason I dropped 1 star off, is that one of my 3 monitors sporadically cuts off and on at times. At first I thought it was the monitor. However, while switching cables around a few times, I realized that whatever monitor was connected to the DisplayPort via an adaptor to HDMI was the one that would do it. So, I'm attributing this to the dock. This issue was noted in a review for the Dell Monitors I bought, but I realized that it wasn't the monitors at all. I will try to troubleshoot this issue if it continues.

Overall, I LOVE this dock. It opened up my whole desktop world. Even the 3 front USB ports are a dream for connecting phones, iPods, USB sticks, or other peripherals. And the best part is that it works with any computer. Dell got it right with this one. I'll be buying more for my kids when they are ready for multiple monitors.
