I have three LG 27inch IPS displays that I used just fine with my 2012 Macbook pro with the 650 graphics ...
1 April 2015
Summary: Purchased this device and it arrived today. I have a Mid 2014 Macbook Pro retina with the Intel Iris Graphics card. Unlike the 750M, this graphics card can only drive two external displays. Either two thunderbolt or ONE thunderbolt and ONE HDMI.
Summary: One big thing though, don't bother with the drivers CD that comes with the display adapter. Instead, go to startech.com/download and look up the driver for 'USB2DVIE3' (this device). The driver bundle from StarTech is named 'Trigger.zip'. I ran the extract and setup.exe to install the drivers first.
Very pleased. Here is how to make it work on a Mac.

Summary: Ok, so this is how to make it work correctly on your Mac (for Mavericks at least, didn't test with Yosemite). WARNING: seems like device won't work with Thunderbolt displays, only Mini-DisplayPort Apple Cinema LED Display-like monitors.

Summary: These work as advertised. I've purchases a number of them and used them on a variety of PCs, from older (5 year old+) models to current models and they just work. Note, I'm using them in a business setting with Windows 7 Pro (32bit and 64bit), not with gaming.
Summary: I can't believe this actually worked just as a video card. I asked my IT person and he said there is nothing out there that would actually work for laptop but this thing really worked on my laptop. I have Toshiba l755 with windows 7.
Summary: This works great. I'm now supporting 4 1080P monitors on my late 2012 Mac Mini with Yosemite! 1 monitor on Mac HDMI port, 1 monitor, on Mac Thunderbolt port, 1 monitor on StarTech HDMI port, and 1 monitor on StarTech DVI port. This is the most real estate that I've ever had on a computer!
Summary: It works OK except the primary monitor keeps flickering when the secondary monitor connected with this device is in use. Eg: if I have my outlook inbox open on the primary monitor which nothing on the secondary monitor then my outlook is fine.
Summary: I usually keep a few of these around for "emergencies", or when that random user just has to have a monitor right away, and these work great. I haven't experienced any of the lag that I was accustomed to with other USB to VGA adapters and it's a great quick and easy solution for adding an additional...
Summary: This is an easy answer to what should be a simple question "How do I add a monitor to my computer?". I have had two different internal cards I had tried; both of them I couldn't get to work. This one was plug-and-play for the most part.
Dual 30" on 11" MacBook Air - Mac OS X 10.9 and 10.10 Yosemite compatibility and comparison
14 November 2014
Summary: I purchased this prior to Yosemite when I was on 10.9 and was fearful of upgrading to 10.10 and not having the drivers be compatible. I bit the bullet tonight and fortunate that everything works as before and feels slightly snappier.
