Most newly purchased computers these days have the native ability to use multiple monitors which is very handy for things like having a document you're working on being displayed on one monitor while you can still do mail on the other. Older computers, such as the one I'm using, only have the ability to drive one monitor. To add a second monitor you need to add additional hardware. I wanted a second monitor, and I bought this Startech unit to provide basically a second video output. It worked perfectly. Note that most external multi-monitor per video adapters require that you have a USB 3.0 output port for the adapter. My computer only has USB 2, which works from a USB 2 port. For my use, document on the second monitor, miscellaneous other activities on the main monitor this works perfectly. Note that a USB 2 port doesn't have enough bandwidth to running something like full screen video. I note that one reviewer gives this device a bad review because it doesn't do this well. His problem is not with this device, but with a limitation of USB 2 that nothing external to the computer is going to fix, He needs a computer with USB 3 or USB-C an an external adapter to match.Read full review

I bought a new computer recently and then discovered it only had USB ports. I use a second monitor and was in a bind since the monitor only has a VGA and DVI output. This adapter solved my problem. I connect my second monitor to the adapter and then plug it into a USB port. The device worked perfectly and I have my two screen set up back. I would highly recommend this device to others who need a second monitor and need to connect to a USB port.
