StarTech.com2-Port Multi Monitor Adapter - Mini DisplayPort to 2x DisplayPort MST Hub - Dual 4K 30Hz - Video Splitter for Extended Desktop Mode on Windows PCs Only - mDP 1.2 to 2x DP (MSTMDP122DP)

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!

I bought two of these and two StarTech mini display port extension cables - Perfect combination for both my home and office setups. I'm running my laptop screen and three 19" full screen monitors simultaneously - with no issues. We ended up getting a few more of these at work after seeing how well they work with my setup. This hub works just as advertised and is worth the money.Those who reported issues of flickering screens are most likely experiencing issues with their own computer hardware (graphics card) and not this device. When I first plugged the hub in, two of the monitors kept flickering - it drove me nuts. Then, I realized I was running all 4 screens off of the chincy Intel on-board graphics card in my laptop. I immediately switched over to the NVIDIA 1060 and haven't had a single monitor flicker since. Basically, make sure your GPU can handle however many monitors you're trying to display across, before just assuming it can handle it - and you should be golden.

Works great! I have two large monitors connected to my Surface 3 Pro which I am loving. My monitors are over 6 years old, so I only get 1920x1080 max display size, but that is not because of this StarTech mini Display Port (DP) to triple standard DP. I bought two cables DP to DVI and connected them to this device. It worked immediately! I Extend the display so that I have additional screen space, not just duplicate the screen.This is the best price I have found for multiple monitor display. Be careful of those multi-port that use the word "expand" or share as sometimes they are only able to duplicate the same screen to multiple monitors.I have two monitors, each with both VGA and DVI input capability. I have a Surface Docking port for my Surface, so I can just as easily connect one cable (mini DP to dvi) from my dock to one monitor and one cable (mini dp to dvi) directly from my Surface (not the docking port) itself to my other monitor. That works equally as well. Having the StarTech port is a convenience from not having to plug in a cable when I dock. Actually, since I don't carry the Surface Docking Port, I can carry this product(StarTech mini DP to Triple Head DP) to remote locations and still have multi-monitor.I'm not sure why this is so expensive. Mac and Windows 7 and up have built-in capability to handle multiple monitors.

Initially, this DisplayPort1.2 hub worked beautifully with my ASUS GL551J laptop (uses mini DisplayPort1.2 connector).It supports DisplayPort1.2, so monitors can be daisy-chained together.I used the hub to output video to 2 external monitors (ASUS VP278Q-P 27" monitors)1) After half a month, the unit does get around 50degree Celsius. (It was too hot to touch until I let it sit for a few minutes)2) As of last week, the DisplayPort1.2 hub stopped working for the right monitor, but continued to output video to the second monitor.3) As of 3 days ago, the left monitor will not work with the hub (both monitors now don't work with the hub)I am not sure if it is an Intel Graphics Driver issue or if the device is damaged internally due to the temperature change.My guess is since the monitors did not drop out at the same time, I am leaning the cause is most likely the displayport hub instead of the software driver on my laptopDo you have any recommendations as the seller? I do not have a way to diagnose the DisplayPort1.2 hub.I included pictures of the Windows 10 settings where Windows can see the monitors, but the monitors are not able to be selected as a display output.I also included the Device Manager view (it now thinks the monitors are 640x480 instead of normal monitor resolution). This picture has the Intel display driver as well.
