5 out of 5 eggs3 HD Displays off My Surface Pro 3!

Pros: Allows the hookup of 3 HD displays to a Surface Pro 3 through the single Mini-Display port.
Works with Displayport to HDMI adapters.
When Plugged in, you can configure using the Windows Screen Resolution Control panel. Windows remembers your setup; when you unplug it all goes back to the SP3 display, when replugged, it takes a moment and then returns you back to your multidisplay setup.

Cons: The Connector is a little short and on the SP3, the Mini-Display port is on the upper right of the tablet, so it dangles when connected.

I have had the device lock up my displays if I tried to enable all 4 displays; you need to be careful and ensure you don't try to enable all 4 displays.

The Windows Resolution Control Panel doesn't report the on screen identification properly, so you need to do a little guessing as to which monitor you are positioning.

Other Thoughts: Startech sent me this product to give them an honest review. It's an excellent accessory. It's nice to be able to drive 3 HD displays from my Surface Pro 3. Typically I use 2 out of the three ports, since I require the use of my SP3's touch screen for development. My monitors are a mix of 2 Dell's and an LG. I have used other non-HD monitors with this, and all the configurations worked.
None of my monitors have Displayport ports, so I had to use 3 DisplayPort to DVI converters, and there's no problem using them.
The only caution is setup can be a little tricky at first, but once setup, I've not encountered any issues.

5 out of 5 eggsThey work great

Pros: They do the job well. Love the available bandwidth of DisplayPort. Showing 71% usage with 3 1920x1200 monitors attached to one of them.

Cons: I have two of these and, it's pretty rare but, sometimes one won't light up. I hardly ever power-off/reboot, however, so no big deal to me. It's as simple as just rebooting again. (again this is pretty uncommon, and from what I understand they have a fix for it, I just haven't noticed it enough to be bothered with it).

Other Thoughts: Would recommend if you truly need mini-dp. Don't use adapters like I tried at first with a standard displayport size (on the input side).

1 out of 5 eggsRun away

Pros: None

Cons: This unit is extremely inconsistent. We had to plug the unit into the PC, then one cable at a time into the unit.. if we were lucky it might work properly in Windows 8.1 -- however if you then unplug it (to say go to a meeting) and come back, you have to unplug all your cables from the unit, and go through this process again, again with no surety that the displays would even come up as expected.

Other Thoughts: not worth it
