Product Description

Size: 3 Ports | Style: Mini DisplayPort

Use this multi-stream transport hub to connect three DP monitors to a single mDP 1.2 port - This MST hub lets you connect three monitors to your Mini DisplayPort (mDP) 1.2 equipped Windows tablet, laptop or desktop. The hub has been rigorously tested to ensure compatibility with the Microsoft Surface Pro 4, Surface Pro 3 and Surface Book. Please note Microsoft Surface products only supports the use of three displays in total. If more than three external monitors are attached, the built-in touch screen on your Surface will be disabled. If four monitors are attached, the fourth monitor will not display any content. Increase productivity with multiple screens The newest generations of computers are more portable than ever, which often means that you’re left with fewer video outputs and smaller integrated screens. This MST hub solves both of these problems by letting you connect three additional displays to your computer, which makes multitasking much easier.  Connect to any display With the MST hub, you can use Mini DisplayPort video adapters and cable adapters that enable you to connect HDMI, VGA or DVI displays. This ensures that your MST hub will be compatible with virtually any television, monitor or projector. The hub is VESA and DisplayPort certified to support DP 1.2 enabled systems, for seamless integration with your existing video equipment. Configure your displays for any environment Using the MST hub, you can extend your desktop onto additional monitors and stream independent content to each display, giving you the freedom to multitask and increase your productivity. You can also mirror the same image onto multiple displays for remote viewing applications such as digital signage.   Enjoy amazing video quality, without draining system resources MST technology uses your existing video card to minimize the use of system resources while delivering Ultra HD 4K resolutions. This unprecedented performance makes MST perfect for high-resolution applications such as graphic design, gaming and medical imaging. Note: When using a DisplayPort 1.1 video card the MSTMDP123DP will act as splitter, automatically mirroring your video source across all displays. Resolution limitations apply. The MSTMDP123DP supports plug-and-play installation for a hassle-free setup, and is backed by a StarTech.com 2-year warranty and free lifetime technical support. Note: MST shares 21.6 Gbps across all attached displays. Higher resolutions can restrict the available bandwidth with the remaining ports, please see our guideline below for determining an ideal resolution for your setup. Certain graphics adapters have limited MST support and will only output to three displays in total. If more than three monitors are attached the fourth will be disabled.

Startech was kind enough to let me review this accessory, and I must say it works quite well. While setting up for my review, I had the misfortune of having faulty DisplayPort cables, but the device works fine with some DisplayPort to DVI adapters I had lying around. I was a little disappointed that I couldn't drive 4 displays off the Surface Pro 3, 3 external + the SP3, but that was probably pushing my luck. It was nice to be able to drive 3 big external displays though, all from the Surface Pro 3's single MiniDisplayPort; leaving my USB3 port open for other accessories, like my Ethernet adapter. My video shows two 3 display configurations I was able to put together at my office. In reality, the way I work is with the SP3 display, and 2 HD displays. I use the SP3 for testing the work I'm doing, while my other displays run Visual Studio, and a debug session. Overall, this adapter is a great productivity boost for my Surface Pro 3. Anyone wanting to drive 3 external displays, or a combination of SP3 and 2 external displays, should look into this; even if your external monitor doesn't use a DisplayPort, the MSTMDP123DP works with converters.

Updated 12/5/2014 - Started to notice a number of issues with the MST not displaying to my monitors unless I re-dock the SP3. Going to ask for an RMA and see if the new adapter will fix this issue.

Just got this adapter today and am using it with the Surface Pro 3 docking station and it works fine. I'm driving two monitors at 1920x1200 with no current plans for a third one, but have that option if I need it. I've undocked the tablet and docked it without sleeping/shutting it down and it comes back right where I left off.

If you're planning on driving two monitors only and have the Surface Pro 3 dock, you could just use the mini display port on the dock and on the Surface while it's docked.

UPDATE 11/20/2015
Barry Watson in Product Improvement did send me another one of these MST Hubs with the new chips and I am happy to report that with a few configuration settings in Windows 8.1 it does indeed work with my Microsoft Surface Pro 3. The setup allows me to have an Asus 24in on the left, my surface in the middle and another Asus on the right. Which allows me to have three desktops. If you are a buyer consider these things first. 1.) Go to the display settings and configure the positions of the display. The identify tool will show you which display corresponds with the number. 2) Pick the display under each corresponding monitor in the setup and pick the monitor model. (This sounds silly but you will see) That should fix the problem. 3) Before returning it try and call StarTech. They sent me a new one because of the reason above. As far as the Apple issue it will work with my MacBook Pro but the con is that it is only a mirror of the desktop on both displays. StarTech says Apple doesn't officially support MST yet.

I just purchased a Surface Pro 3 with an Intel i5 Processor. Before purchasing I had done tons of research on the best solution for my dual Asus Monitors. I contacted StarTech and through the chat, the adviser told me that my Surface Pro supports Multi Stream Transport(MST) which is needed for this hub. He also said it is supported on my Early 2013 MacBook Pro. So I ordered the cables that they recommended which were $30 each and were DisplayPort to DVI. I got charged for the cables first then waited weeks to get the product because it was on back order. Finally when they got more after a week of waiting I was told they don't have any more. So I decided to order it from the retailer on Amazon. I tried first plugging this into my Mac.

The StarTech.com MSTDP124DP DisplayPort to 4x DisplayPort Multi Stream Transport Hub works as advertised. I have four monitors attached to it, all are working fine with this product.

Setup was not as straightforward as suggested in the manual. After connecting the device (and the monitors) the PC should recognize all monitors after startup, however I had to reconnect some of the monitors a couple of times while the PC was running in order to get them recognized. It took me about 15 minutes and a couple of reboots in order to have the setup working.

Pro-Tip: if one of your monitors does not get recognized immediately on startup, disconnect the monitor, reboot, and reconnect the monitor while windows is running. If two monitors are not getting recognized, disconnect both, reboot, connect ONE of the missing monitors, reboot again, THEN connect the second missing monitor.

Please note that once windows has recognized all monitors it continues doing so, meaning no more hassle afterwards.

Only con I can list has not really something to do with the product but with the DP 1.2 standard. Many users (also me) have issues with their monitors to wake up after sleep (it's a known DP 1.2 problem when using MST's and/or daisychaining according to google, forcing affected users to hard-restart the PC each time it happened). Only solution for me was to disable "turn off the display" and "put the computer to sleep" in the power options of windows.completely.

Still, I prefer DP 1.2 over my old setup (external USB 3.0 graphics cards using displaylink technology), even with the limitation mentioned above, due to better performance.

So, in a nutshell, if you want to run a multi-monitor through one displayport, go for the product, but be aware of the known bugs of DP 1.2 (which may or may not affect you).
