3-Port Multi Monitor Adapter - Mini DisplayPort to DisplayPort MST Hub, Dual 4K30Hz & 1x 1080p - Video Splitter for Extended Desktop Mode on Windows Only - mDP 1.2 to 3x DP (MSTMDP123DP)

I wanted to connect two monitors I have to my Surface Pro 3. After doing a research, I found out that there are few dependencies to get to extend your SP3 to 2 additional screens, one of them is the model of the SP3 you have. Anyway, after buying this, I managed to connect my 2 ASUS monitors using a DisplayPort -> HDMI cables. These cables were connected to this piece of Mini Display Port that I bought from Amazon and it's working well. Now, when I bought this piece, I wanted to use it for my SP3 as well as for me MacBook Air. That being said, it did not work with MacBook Air which I have. After doing a research, I found out there are few elements a person should research before buying or investing in such a piece. 1. Make sure your graphics card is capable of extending into few additional monitors and the resolution it can extend into to. (It was important for me to get the SP3 to extend at 1920*1080 on both 27" monitors. Without a graphics card that can do that, this piece may not be able to give achieve this. 2. Make sure your get the right cables. I got this piece and I overlooked the fact it is Mini DisplayPort to DisplayPort converter, I "assumed" it was to HDMI. Nonetheless, I managed to go to a local shot and instead of buying DisplayPort to HDMI converters, I invested in 2 DisplayPort to HDMI converters. Some of the cables I tried at the shop were faulty and hence after trying 5, we managed to find 2 that were working. 3. Finally, make sure the graphics card driver is up to date. Check the driver website of your monitor manufacture and download/install the latest drivers. Good luck!

So I have been using this product for about 2 years on my Microsoft Surface Pro. At first, it worked and then sporadically didn't. Very frustrating, but it never really seemed to be a problem with the device. What it is doing is fairly simple and it seemed more of a Windows problem. Low and behold it was. Windows went through several patches to support upgrading its Mini Display Port capabilities. When 10 came out, everything quit working but soon thereafter a couple of patches the MST is working great and I can say that I have had no issues for about a year. Very happy with the product and glad I stayed with it. Would recommend it, but not for a novice just for the simple fact that there can be some O/S complications that need to be worked through.

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. It only detected one monitor. So I was able to extend to one monitor and the other monitor was mirrored. I was told by StarTech that I would be able to extend to both monitors. Next I tried my Surface Pro 3. Even worse it only picked up 1 monitor and the other wouldn't work. I've looked at all the settings and it still doesn't detect. I simply returned the product to the retailer in Canada and am taking the 25% restocking fee as a hit for a product that many people complained doesn't work. I Googled some forums and they suggest a port replicator with an HDMI and USB Adapter.

No sirve en Mac, estaba barato y lo probaré algún día en PC, no se compara con una matrox

fantastic and reliable product and brand, does the job.

Didn't work for me. Apparently it can't draw enough power from the laptop for my 2 gaming monitors which led to my monitors flickering on and off. Might be ok for other monitors or even a single. Not sure.

Ich habe mir schon lange gewünscht meine Arbeit auf einem kleinen, praktischen, aber leistungsstarken Ultrabook ausführen zu können. Mobil unterwegs, stark im Büro - der übliche Setup halt... mehrere Monitore, viele Fenster offen, Virtualisierung, usw. Was mir bis dato immer im Weg gestanden ist war diese ganze Display-Port Geschichte bei den Ultrabooks (nur ein Ausgabeport), denn was genau bringt mir ein praktisches Ultrabook wenn ich für meine Arbeit an mehreren Bildschirmen dann doch wieder einen Desktop oder ein altmodisches Notebook mit mehreren Ausgängen brauche? Ich habe zuvor bereits mit anderen Geräten herumgespielt um dieses Manko loszuwerden, fast alle basierend auf DisplayPort (diesen üblen USB 3.0 zu Display Adaptern). Diese waren zwar preislich leistbarer (oder so schien es zumindest), hatten aber diverse für mich katastrophale Nachteile / Inkompatiblitäten: 1. Sind diese USB Adapter alle nicht mit Linux kompatibel, und der Hersteller weigert sich die Treiber dafür rauszurücken. 2. Ist die Performance (getestet unter Windows, da Linux Treiber ja, wie in Punkt 1 beschrieben, nirgendwo auffindbar waren) einfach katastrophal (man denke hier an Mauslags, usw). 3. Stellen diese USB Adapter (die meisten, nicht alle) nur einen weiteren Adapter Anschluss pro USB 3.0 Port zur Verfügung (und diese sind auf einem Ultrabook sowieso Mangelware). Aus Verzweiflung musste ich dann leider doch die Geldbörse zücken und diesen doppelt so teuren StarTech Multi Monitor Adapter kaufen, und nun will ich dieses Teil nicht mehr missen. *) 100% kompatibel mit Linux (Arch Linux bei mir, aber generell sollte DisplayPort Multistream auf allen üblichen Distributionen laufen) sowie Windows (angeblich auch mit Mac, aber das kann ich nicht testen). *) Keine Ausfälle, keine Mauslags, alles super flüssig. *) Und keine belegten USB 3.0 Ports mehr da alles über den Mini DisplayPort meines Ultrabook läuft. In diesem Fall kam das Sprichwort "Wer billig kauft, kauft öfter." in vollem Umfang zur Geltung. Kurz zusammengefasst, einfach großartig - und eine wunderbare Ergänzung zu jeder mobilen Workstation. Das einzige Manko das ich hier finden kann ist dass die Platzierung des Anschlusses für den AC-Adapter etwas ungünstig (auf der Vorderseite, zusammen mit dem Mini DisplayPort Kabel), und das Kabel des Adapters mit rund einem Meter doch sehr kurz ist. Auch das fest verbaute Mini DisplayPort Kabel ist mit knappen 10cm (inklusive Stecker) etwas kurz geraten. Hier wurde eindeutig an der falschen Stelle in der Produktion gespart. Trotz dieser kleinen Kabelproblematik gebe ich dem Produkt die vollen 5 Sterne da es (nach langwieriger Suche) nach wie vor das einzige Produkt ist welches das Multi Monitor Problem in einem < 100€ Rahmen löst. Volle Kaufempfehlung meinerseits.

After seeing all of the hit and miss reviews on Amazon.com's review section I was hesitant to buy it. I can probably safely assume this is the version 2. It works perfectly though, been about a week now running 3 identical new LG IPS displays I got on Black Friday. It's not being run off of a Surface Pro 3 like almost every one that bought it however. Not a single hitch to be seen so far including waking from sleep, startup from shutdown, monitors being turned on or off while in use. I'm also running 3 full display port to hdmi adapters because my monitors are lower end IPS and only have HDMI and VGA. This is another factor that could have led to failure to run this hub properly but it's handling it like a champ. This is all on Windows 10 as well. I'd like to think the issues other users had have more to do with their hardware or other factors because I haven't experienced a single problem that was mentioned. I feel it was well worth the money and would recommend it. If it's possible to edit a review, I'll update it if it does give me problems. Edit: Almost 1 year has passed with it. Absolutely no problems, it runs flawlessly. Thought for sure by now I'd have issues with it but it's doing well.
