Know your gear

This MST hub lets you connect three DisplayPort monitors to your Mini DisplayPort computer. MST works on any Windows® device that supports DisplayPort 1.2, such as models of the Lenovo™ Think Pad® and Microsoft® Surface™. When connected to earlier revisions of DisplayPort, such as DP 1.1 the MST hub acts as a video splitter.

Increase your productivity with multiple monitors

The newest generations of laptops are more portable than ever, unfortunately this means you’re left with fewer video outputs and a small integrated screen. The MST hub solves these problems by letting you connect three independent displays to a single mDP port on your computer, which makes multitasking much easier. Using the MST hub, you can extend your desktop onto additional monitors and stream independent content to each display, which makes it easier to multitask and increase your productivity - perfect for creating an easy-to-dock hot desk solution with a wireless keyboard and mouse peripheral set. You can also mirror the same image onto multiple displays for remote viewing applications such as digital signage.

Increase Productivity with multiple screens

Astonishing picture quality that won’t drain your system resources

MST technology uses your existing video card to minimize the use of system resources while delivering Ultra HD 4K resolutions. 4K is supported by the latest A/V devices and delivers four times the resolution of 1080p. Plus, because the MST hub can output high-definition 1080p, the MST hub is perfect for all high-resolution applications such as graphic design and medical imaging.

Works with any monitor, television or projector

With this MST hub, you can use separate mDP video adapters to connect HDMI, VGA or DVI displays,  for compatibility with all of your existing monitors. The hub is VESA and DisplayPort certified to support DP 1.2 enabled systems, for seamless integration with your existing video equipment.

Extend Your Compatibility

The MSTMDP123DP has been certified by Microsoft and tested for compatibility with your Microsoft Surface Pro 3, Surface Pro 4 and Surface Book and is backed by a 3-year warranty and free lifetime technical support.

Better Together Mini DisplayPort to DP Multi Monitor Splitter - 3-Port MST Hub
Quick View
Total Price: Mini DisplayPort to DP Multi Monitor Splitter - 3-Port MST Hub is rated3.05 out of5 by19.
Rated 5 out of 5 by from Works with DVI out not VGAConnecting monitors via DVI seems to work as expected and without issue, just make sure you get a DVI-D cable, other DVI cables I tried did not work. I would expect HDMI and Display Port to be fine as well but have not tested.When using this splitter, using converters to VGA (even the ones offered by StarTech) will cause instability and inconsistency between dockings. Screens flicker, resolution of monitors is recognized differently between uses, video driver occasionally crashes.

Rated 5 out of 5 by from Doesn't work with Surface Pro 3So I got one of these to use on my new Surface Pro 3 tablet. They have a decent looking and feel, and while my HP LED screens do have Display Port 1.2 connectors, I can't have any of them detected by the tablet while using the MST adapter. I've contacted the StarTech support, which told me this dongle should work with the Surface and he suggested me to replace the unit, which I did and it didn't worked either. As the docking station was due to be out on the market soon, I waited until the day I got mine, and here I am writing using my Surface Pro 3 while docked. The dongle still does not work. The tech support told me it was tested and made for the Surface Pro 3, so either I got a pair of duds or that was a sales rep acting as a tech. At any rate, if you plan on expanding your Surface Pro 3, don't bother with this adapter. Instead, use two cables: one at the dock and another at the Surface itself - or have fun with another MST hub from a different manufacturer.

Rated 5 out of 5 by from Simple and worksI have purchased five of these for use with the Surface Pro 3 and we have had no issues. Every installation has been less than 10 minutes and my users were able to configure their own screens.

Rated 5 out of 5 by from DisplayPort MST Hub does not work with Surface 3 & Docking StationI have only used this device with Microsoft Surface 3 Pro, and docking-station. Connected to two external HP EliteDisplay E241i.While you can get this MST Hub to work as intended for a short time*, I have not been able to stabilize functionality to the point where I would deploy in to end users.* Disconnecting and reconnecting power supply to MST Hub, and powering off/on the external monitors will make the Surface 3 Windows OS detect and enable the connected displays. The external monitors will work until the next time they enter sleep mode. After that, the Surface 3 in docking-station will no longer detect the external monitors,You can repeat the MST HUB, and Monitor power reset process and have external monitors working again, but only until next monitor sleep event.The device itself appears to be well designed, and the connectors feel solid.Unfortunately, my experience with this device is similar to previous review and until this issue has been addressed by StarTech - I would not suggest attempting to use this device with the Surface Pro 3.

Rated 5 out of 5 by from Worked like a champOrdered with a new Surface 3, Connected it to two monitors and went into the windows software and enabled and extended the monitors and everything worked just like it should. It's a great alternative to buying new monitors with display port in and out when upgrading users to a new surface tablet and wanting to run multiple monitors.

Rated 5 out of 5 by from Useless with ASUS N550JK and 2x acer CB280HKDoes not work reliably with Windows 8.1 on ASUS N550JK and 2x acer CB280HK.There must be a magic order of actions to power it on, plug in the monitors and recognise them in windows.But it isn't working for me.I got it to work only once, and it was stunnign with two 4K2 displays in portrait mode.Buyt I walked away from my desk to get lunch and it hasn't worked since.your mileage may vary.but prepare for no miles at all.

Rated 5 out of 5 by from Only detects one monitor at a timeThis had promise but on a surface pro 3 w/o docking station, the MSTMDP123DPonly detects 1 of 2 27" Samsung displays.

Rated 5 out of 5 by from Only one monitor with Surface pro 3Just got this in and installed it on my Surface Pro 3 - it supports a second monitor - and the third monitor winds up displaying the same as the second (assuming the surface pro display is monitor one). Bought this because I assumed Star Tech would simply work - very disappointed.

Rated 5 out of 5 by from Very DisapointingI bought this to work with the Surface Studio 1 and the Samsung CHG90. it is a no go and there is very little information about which display adapters/driver pairs actually work with the device. I am sure when it works it is great, but when it does not it takes hours to test everything to find there is not solution.

Rated 5 out of 5 by from Increased ProductivityI absolutely love the 3-Port Multi Monitor Mini DisplayPort to DisplayPort MST Hub that I was selected to try out for free. As a software developer this allowed me to easily have multiple software programs open to write code, test the code on a separate screen, and then check the data on the third screen. I`m sure my boss will like me being more productive as well. I`ve only had this product a little while and I`m already wondering how I ever was able to do it all with just one screen. Once I got all the correct adapters for my monitors the setup was a breeze. I will definitely be recommending this to others I work with as well.

Rated 5 out of 5 by from Great SplittersI received this free mini display port splitter to review and it`s been working great - no problems at all. I typically run 2 monitors, but this has allowed me to bump that up to 3 - super useful. Picture quality has been great throughout the time that I`ve used this product. Easy to use, just plug it in and it works, way better for multitasking.

Rated 5 out of 5 by from So far so goodJust got it and it has been plug and play with my Surface Pro 3. I haven't tested daisy chaining Display Port or use with a variety of monitors, but so far it displays to my Dell 28" P2815Q via Display Port as expected. I may bump up/down the stars after I test it some more.

Rated 5 out of 5 by from It workedSo I received a free sample of the Mini DisplayPort to DisplayPort Multi-Monitor Splitter - 3-Port MST Hub in order to complete a review. And first things first, while DisplayPort is an extremely underrated technology, HDMI has become the standard for HD display chords, so a majority of people will find the HDMI version of this product to be significantly more useful. That said this product aimed to turn a single mini DisplayPort into 3 DisplayPorts, allowing for a computer to use 3 additional monitors. This splitters gets the job done and it succesfully integrates into Windows 10 display settings extremely well. Additionally, the product has a solid, compact design, which you notice right when you take it out of the box. One negative is to use the splitter, you have to use its included power supply, which is pretty bulky. My favorite secondary feature was the multiple power adapters, which allowed the splitter to be used all over the globe! And as far as design, the material used for the cord leading to the mini DisplayPort was extremely firm and stiff, which lead me to believe it would last a long time (I`ve only had the product for 3 weeks). Lastly, I never needed to use the integrated scan function and there wasn`t any instructions in the provided manual, so that seems like a wasted capability. Overall, StarTech`s Mini DisplayPort Splitter worked as advertised and successfully expanded one mini DisplayPort to 3 DisplayPorts!

Rated 5 out of 5 by from Sketchy at bestI bought the hub doesn't work as well as promoted on StarTech web site. Sketchy at best with setting up with my Surface Pro3. Every day is an adventure to get my two 27” BenQ monitors up and displaying. I am constantly resetting my display options to get it to work. This waste time in the morning up to an hour a day. In a nut shell doesn’t work out of the box.

Rated 5 out of 5 by from Nice product! Works perfectlyI received a free sample of the Star Tech Mini Display Port to Display Port MST Hub to review and found it to be of very good quality. It worked perfectly on my Elitebook laptop at work with Windows 7. I just plugged in all monitors (3 24" monitors) , then plugged it into the computer. There are a few noises when they are booting up, but then all four monitors (including the laptop) working perfectly. It took a little while to configure the resolutions and positions and setting the wallpapers for all the monitors, but is was very easy. I was able to play 1080p 60fps videos on all four monitors simultaneously without any issues. Overall I would give this item a positive rating.

Rated 5 out of 5 by from Works GreatI bought this to connect to 24" 1080P monitors to my SP3/dock. Works well, and has no problem with the the monitors native resolution. Plug and Play so setup was as easy as plugging everything in.

Rated 5 out of 5 by from Overall happy with product, works as I expectI received this splitter after agreeing to provide an honest, accurate review of this product. I work in an IT field and my job frequently requires the use of multiple monitors on more than one computer so I was looking forward to giving this product a try.I`ve been using it for just over a week with one of my work laptops that has a mini-display port. It runs Windows 7. I typically use three monitors at once with this machine. This is easy to do at work where I have a docking station. At home I do keep a docking station around but it takes up too much space on my desk so I`m not a big fan. I like this device as it is relatively quite small. There isn't much to do in regards to setting it up. I just plugged in the display port cables from my monitors into the splitter and the mini display port into my laptop. The device does need to be plugged in for power. It comes with several different adapters for power. I live in the US so I simply had to identify the correct adaptor for the splitter and attach it. In all it was very easy. I've been using it for a week now. I haven't noticed any problems. My monitors all display as they should. If I had one request, it would be to make the Mini DisplayPort cable longer. It`s a fairly minor concern.

Rated 5 out of 5 by from Useful once I got it working - needed an adapterThe Startech display port works as expected once I got it up and running. I found that I needed a HDMI adapter which would have been nice to have been included in the instructions. I found out by visiting the website. Then I went on a quest to find the right adapter which was hard to discern from the site. I saw the picture of it but no link to the actual product or product number. I ended up using the website Help chat which was helpful but I was told to get a Display Port to HMDI converter cable that in the end didn`t work. Luckily I found the related adapter easily on a popular ecommerce website (since it was an option on the cable product page) and ordered that at the same time figuring I would try that if the cable did not work. Btw, if you need to connect to HDMI the correct adapter is DP2HDMI2 DisplayPort to HDMI Video Adapter Converter Model Number: DP2HDMI2 . Knowing this ahead of time would have saved me a lot of time and frustration. It also would be helpful if this display port had a power indicator on it. As I was troubleshooting I found myself wondering if it was getting power with no way to tell for sure (until I finally got it working).

Rated 5 out of 5 by from Works great, with a catch.I bought several of these from CDW. Lots of informative pics including one with the Surface Pro. What wasn't mentioned is the included (but not pictured) A/C adapter is required to power the splitter. Not a big deal for some, but in my case was an issue.
