Pros: Used with the Microsoft surface dock for surface pro 4/surface book to allow dual monitor setup (three monitors if you include the mDP from the surface pro 4 itself). The surface dock requires an active mDP adapter for some use cases. In my case, the second monitor plugged into the dock requires this active mDP cable.

Currently using a BenQ BL3200 (mDP to DP) and two Dell 2007FP monitors (mDP to DVI) in portrait.

Cons: none so far

Pros: ease of use,one lasted just under 2 years,one is still going strong at the two year mark,no noticeable latency,no problem with eyefinity setup,5 star native English speaking not outsourced phone suppo

Cons: My sample group of two adapters is small, but it may have been an oddity to have a bad one.

Other Thoughts: Purchased two of these to drive a second and third monitor for an eyefinity setup on 2/24/13. An XFX 7970 driving three AOC E2460SWD monitors. I built the setup for gaming, but would often do some take home work on it, as well (spreadsheets at 5760x1080 like a boss!). One stopped remaining connected intermittently when switching between a full screen game or application and windows. Troubleshot it to not be the port on the GPU, not the DVI cables, and not the monitors. Called their support team and began painless RMA process. If that goes as well as everything to date I will revise review to 5 stars.

Pros: Worked most of the time.

Cons: Occasionally would fail on resume from sleep mode. Totally failed after about 1 year of use.

Pros: -Works great with my R9 295x2 and three 1920x1200 monitors. I'm using these for my surround monitors while the center monitor is using the only DVI connector on the card.
-Overall quality seems very high.

Cons: Pricey for an adapter, but I guess converting display port to DVI is not as simple as splicing wires and soldering to compatible connectors.

Other Thoughts: Because of the added weight of the adapter, I recommend bracing the wire on something to keep weight off the display port connection on your video card/cable. In my case I just ran the wires over my desk to prop the wire up horizontally.

Pros: when it worked it was good

Cons: stopped working after a few weeks

Other Thoughts: if this is not rectified i will not use startech again

Pros: Had this for voer a year on my eyefinity setup was skeptical as first but has been working since I purchased it.

Cons: none yet

Other Thoughts: idk if i was lucky but after seeing other reviews of cutting off after 1-7 months mine is still going strong after 13 months.

Pros: Worked great when it did work

Cons: After about 7 months I started getting intermittent video failure after weird tearing on the monitor I had it hooked up to when playing games (eyefinity setup). The last time I had this issue was when I was using a cheaper semi- or non-active adapter.
Definitely going with Sapphire this time.

Pros: none

Cons: DOA. Never worked.

Other Thoughts: I thought I might have been unlucky, but it seems to happen to a number of people. I will be looking for another brand, so should you.

Pros: did it's job when it worked.

Cons: pretty pricey for an unreliable product. After about 5 months of use on my 3 monitor set up, it started to only display my monitor at 640x480.

Other Thoughts: I really wouldn't get this adapter, from what I understand the reliability of it is pretty hit or miss. no need to spend so much on an adapter that is probably going to stop working properly

Pros: Nice design, sleek and feels quite durable

Cons: Highly unreliable. I have a 12-display set up for day trading, and I've gone though 17 of these adaptors before having to switch to other (cheaper!) brands. I'm done with the hit and miss quality of their product, while they charge more than other competitors

Other Thoughts: Be warned, you maybe have to go through two or three to find one that works correctly!
