StarTech.com USB 3.0 to HDMI / DVI Adapter - 2048x1152 - External Video & Graphics Card - Dual Monitor Display Adapter Cable - Supports Mac & Windows, TAA (USB32HDDVII)

This little box is a life saver. If you have a laptop without a dual display output (both HD), this is the device you need to extend your desktop. My wife has a Lenovo Yoga 11S which has a maximum resolution of 1366x768. She currently runs HDMI output to a Philips 246V5LHAB 24 inch LED monitor. The latest display drivers allow her to output Full HD over HDMI to her primary monitor and this device also outputs Full HD to the second identical Philips monitor. This device is plugged into a four port USB Amazon Basics hub. With the device plugged in at first, Windows didn't recognize the second monitor until we put in the installation CD. As soon as the CD was popped in, the second monitor came to life in Full HD. We also setup this device running on her Macbook Air 11.6 (March 2015, Yosemite). It works flawlessly. You only need to ensure you install the right drivers since there are multiple sets of drivers for Yosemite alone so check your version before installation.When we put her laptop to sleep (running Windows 8.1), we didn't run into any sleep issues with having both monitors wake up from sleeping. This also was not an issue using the Mac.Installation: 5 starsNo issues with the setup using the included CD. Plugging in the cables was a snap. For Mac, I was too lazy to find where we stashed the CD so I just downloaded drivers online.Design: 5 starsThis little device has a really small form factor which makes it portable in case you want to plug it into another dual monitor setup (i.e. home versus office).Value: 5 starsThe device is great value for the money. If it ever dies, we'll just get another one.Final Thoughts:We are extremely pleased with my wife's new setup. I saw drivers for Linux as well. We also have an old Dell laptop running Mint on a swapped solid state (boots super fast). I bet this would work for the Mint laptop as well. I'll update this review if I try out this box using Linux.Update: I finally tried it on our Mint Linux laptop. Unfortunately, it didn't work as the drivers were designed for Ubuntu. I did see a comment someone posted on their website when I searched for "displaylink mint linux driver", but it was kind of involved and a single large screen is good enough for us when we want to use the Linux laptop. We moved the box downstairs to install on an old HP Core 2 Quad (hard drive switched to solid state) and it works fine on Windows 10.

Excellent, bought it to hook up a third monitor to an M1 Mac Mini, which only supports two monitors. Toss the driver CD and download the drivers from the site. Downloaded drivers, rebooted, plugged in monitor, and it worked. Great product.

StarTech... if you're reading this, try to fix this, please! I even did analysis and found a workaround for you. The least you can do is take my assessment into account and resolve the issue.Minus 1 star for the fact DisplayLink/StarTech cannot introduce drivers/software to resolve the adapter sleep issue. If I had not figured a solution out on my own, this product would have received only 2-stars.This device is perfect, after I created a batch script to fix the issue where the two external monitors would stay asleep after the computer has been awaken. Will explain how to create your own after the "Cons" section below.Some people have mentioned this occurs to them once in a while. For me, the issue occurs most of the time after the computer wakes from sleep mode.Pros:1) When functional, delivers perfect digital video/audio (audio on HDMI port only) to two external 1920x1080 monitors over a USB 2.0 connection. The device is connected to a hub, which also connects the keyboard and mouse.2) Can display dvd quality to the two external monitors simultaneously, without too much cpu usage.3) I can't speak for gaming, but my primary purpose is to use my laptop as a development machine. For development and other office functions, the adapter is more than adequate.4) Works with Mac Mini running Lion OS as well. No wake-on-sleep issues, like I encountered on Windows 7 and 8 computers.5) Self powered. No additional power required.6) Customer service. They weren't able to figure out the issue, but at least they tried.Cons:1) The two external monitors connected to the adapter typically do not function after the laptop (Windows 8) resumes from sleep mode. I would have to unplug and reattach the USB cable to re-enable the adapter. This is not a good solution, as I'm trying to minimize the wear to the USB port and it's a pain to physically unplug/reattach the USB cable.Fix:I contacted StarTech regarding my issue. They told me that I should disable "Allow the computer to turn off this device to save power" for the USB Hubs listed within the Device Manager section. Unfortunately, they ignored the fact I told them the issue occurs, REGARDLESS of whether I connect the adapter directly to the laptop OR via a USB hub. But, as I said before, they tried... btw... I did try their recommendation, even though I knew it would not work. It didn't work...Then, I performed some analysis of the processes running on my computer and discovered there is a Windows service that controls functionality and communication between the computer and the adapter... the DisplayLinkService.Through the Windows Services management console, I was able to re-enable the two external monitors by restarting the DisplayLinkService.Therefore, I created a batch file (FixDisplay.bat) and added the following three lines to the batch file and saved it to my desktop for easy access:sc stop DisplayLinkServicesleep 2sc start DisplayLinkServiceLet me explain each command, so you're aware of what's going on and to assure you this is not a malware script. First line stops the DisplayLinkService. Second line pauses the batch request to allow the stop batch request to complete. The final command line starts the DisplayLinkService.Now, whenever the external monitors do not wake up after the computer wakes from sleep mode, I simply double-click the FixDisplay.bat file that I saved to my desktop. Just a note... depending on your UAC setting, you might have to enable the batch file to run under an elevated account (i.e. Administrator), as the commands in the batch file start/stop an installed Windows service.The best solution would be if the drivers actually worked flawlessly to wake up the adapter properly. But short of DisplayLink and/or StarTech fixing this issue, my ad-hoc solution works. The solution definitely beats unplugging/reattaching the USB cable that is inaccessible.

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!The latest driver from StarTech's site mentions OS X Mavericks but not OS X Yosemite, so I was curious if it was going to work. When I tried to install the driver from StarTech's site, it reported that I already had a newer version installed. Say what?Well, I was actually replacing an IOGear USB 2-based Video adapter with this StarTech unit. It turns out that the IOGear unit was a DisplayLink-based adapter, just like the StarTech unit, and I had already installed the latest driver directly from DisplayLink's site for the IOGear adapter (DisplayLink Mac Driver V2.3b). This driver was a beta version that supports Yosemite. And this driver works great with the StarTech unit, too.I hope that this helps another Mac user.
