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

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/B01EY67S6OThe 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!!!

This worked like a charm for my laptop 3 monitor setup. Just make sure your lid is closed on your laptop, most can only handle 3 monitors at a time. I tried the other popular HDMI to Display Port hub and it did not work at all.

This product seems to work okay at first for certain monitors. Your mileage may vary. If you have three identical monitors, this product will probably work. But here are the problems that I unfortunately experienced, and I really hate to write bad reviews but these are the facts:1. It does not work correctly for 2 of my monitors. It makes the image shifted so there is a black bar, using only 90% of the available pixels. No changes to the display settings in Windows will fix this.2. It blew out a line of pixels in my 3rd monitor. It does display 100% of the pixels on this monitor, but it caused a random line of pixels to turn purple and this is permanent hardware damage.I don't know if there are other factors that could lead to these problems such as (a) the DP->DVI cables, (b) a power surge, or (c) the particular monitors I am using. But I mean there are published video signal standards and stuff so there is no excuse for incompatibility - who is at fault I don't know.YMMV maybe I got a lemon.

Got the 1 mini display port to 3 display port adapter. I was able to use this to connect to my surface laptop v1 to 2 additional external monitors to extend the display, it was easy to connect, no setup needed . I was previously using my surface laptop with a remote desktop to with 1 external monitor via a mini display port to hdmi cable and I was experiencing a slight lag when I used remote desktop. I've noticed that since using the display port inputs on the external monitors now there is no longer a lag with remote desktop. One point of concern is while I was rearranging my external monitors I noticed the display connection was cutting in and out. If I handle and move around the adapter the display connection will cut in and out which makes me think the connection is not great, once the adapter is stationary and not moving around it works with no issues.

I've been using this for a week, and it works beautifully. Because of the coronavirus pandemic everyone in my office was ordered to work from home. My home setup is an Asus ROG 752 gaming laptop with a wireless keyboard and mouse and connected to two 24 inch monitors via this MST hub. In extended desktop mode, the laptop screen is mirrored on one monitor, and the desktop is extended across the second monitor. The only setup that was required after connecting the MST hub was to specify the scale, layout, and resolution in the Win 10 Display Settings.The GeForce 980M video card has 4GB of RAM and displays a resolution of 1980x1200 on each monitor. I wish I had 8GB of video RAM to get a higher resolution.The MST hub works perfectly. There is no flicker or delay. I can attend a Zoom meeting on one monitor and remote login to my office on the other monitor. When the meeting ends, I stretch the remote login window across both monitors.
