I've got a laptop setup as I cant afford a pc atm. I have this running through one of the usbs on my laptop and it works great. Just set my settings to not turn off laptop when closed, turned off my laptop display, made one of the monitors the main display then extended it to the other monitor. Not much of an input lag either while gaming. Would reccomend.

My laptop only has 1 HDMI port, which meant that I could only add a single additional monitor. I needed a USB adapter to add a second external monitor. This little device did the trick. Now I have 3 monitors (including the built-in monitor) and after some adjusting in Windows 10, I have 3 monitors that I can scroll across continuously left to right and have multiple windows open. This is huge when I am working in Excel, PowerPoint and Chrome at the same time. I can even stream videos and music from YouTube and work on the other screens. Very good product. Simple to use by downloading some software and following the instructions. Takes just 5 minutes or so.

Nice flag MADE IN THE USA
Updated: I was a little bit skeptical at first about this, I am using it to power (2) NEC EA243WM 24"" 1920x1200 monitors and while it worked initially now each time I shutdown or reboot my computer I have to wait until windows loads and unplug it and plug it back in. Windows 10 shows it I’m device manager, but it won’t output anything onto the monitors until you unplug and plug it back in. After dealing with it not being recognized you get a good quality image. The refresh rate is good and I don't notice any difference from the other two NEC's that come right off my laptop docking station. I haven't tried to push 4K using it, but for 1920x1200 it works great.
