Accell mDP-2DP Multi Monitor Splitter - Mini DisplayPort 1.2 Multi-Stream Transport (MST) Hub - 1x Mini DisplayPort connector, 2x DisplayPort outputs,Black

Surface Pro2 からドッキングステーションを経由して、このケーブルで分岐しFlexScan EV2730Q 2枚を接続しました。 最初はどちらか片方しか認識しなかったのですが、現在は両方とも、1920×1920 で認識しております。 手元のSurfaceの画面と合わせて3画面、個人的には理想の環境が整いました。 その後、 １．メイン画面と本製品に接続した1画面しか認識しない状況に再度なってしまったのですが、 本製品に付いているUSB給電をドッキングステーションから分離して独立して電圧を供給したら3画面状態になりました。 ドッキングステーションのUSBポートに戻すとやはり3画面にはなりませんでした。 （ファームウエアの更新等でドッキングステーションの電圧供給仕様が変わったのかな？） ２．次に、似たような現象が生じた時、ドッキングステーションからSurface Pro2を外して、Surface Pro2に直接本製品を接続すると使えるようになりました。使えるようになった後に、ドッキングステーションに戻せば、そのまま継続使用できました。

I am not much of tech person, and was worried a bit, but it was as easy as plug & play. both monitors and lap top screen are working the only issue (which goes back to my tech knowledge) is that it needs a strange connector, I thought it is HDMI by looking at the picture, so I ended up baying two convectors, yes it is annoying.

EDIT: I bought & installed this in Feb 2018. It is now Mar 2020, and it still works perfectly. I just started working from home and bought a second one for my work laptop. It works great too. This MST hub works perfectly with my Microsoft Surface Pro 3 tablet and Microsoft 3Q9-00001 docking station. It works equally well when plugged into the built-in mini Display Port on the Surface tablet, or when plugged into the mini Display Port on the docking station. I am using it with two monitors that have HDMI inputs. I bought cables that go from DisplayPort to HDMI. Here's the link for the DisplayPort-to-HDMI cables (copy it and paste it into your browser's address bar): https://www.amazon.com/gp/product/B01EY67S6O The whole setup works perfectly. It took me less than 5 minutes to setup. Via the Windows 10 "Projector" menu (press-hold the "Windows" key on the keyboard, and tap the "P" key to access this menu), I can choose to mirror or extend the display. "Mirror" displays the same image on all three displays (built-in surface display plus two external monitors). "Extend" allows me to display different windows on each of the three displays. The docking station also has 5 USB ports, allowing me to plug-in a full-size desktop keyboard and mouse. The combination of this MST hub, plus the docking station, makes my Surface Pro 3 a true "desktop" PC!!!

The device appears to be of good quality. We're waiting for cables to connect it properly. After a couple days, 1 of the monitors quit working, it went into Power Saving Mode. I exchanged the cables and it didn't help. Troubleshooting points to the Accell device. Please advise.

Stopped working after 3 months. Now monitors flicker back and forth. Disappointing
