Review on StarTech.com USB 3.0 to DisplayPort Adapter 4K Ultra HD, DisplayLink Certified, External Graphics Card - Mac & Windows (USB32DP4K), Black by Matthew Seamster

. The last one confuses me the most, but the battery life and fast performance worries me less. However, this unit allows me to add a second external display to my setup, which I very much prefer. You have to install the drivers, but this experience is seamless. The only downside is that the Apple Watch integration with the MacBook suffers while the display drivers are active. Has something to do with the screen recording being present. I hope they fix that and the lack of support for multiple external displays, but until then that will do.
