Laptops work through the dock as if they were connected directly. A slight performance lag on displays is barely noticeable and worth the added convenience. Optimum viewing resolution will vary from one machine to another. Our test MacBook (running Mountain Lion) worked best at 1,680 x 1,050, despite a monitor that's usually set at 1,920 x 1,080. There are other known issues with Mountain Lion, including an inoperable audio output jack and intermittent blank screen when returning from sleep. Return from sleep worked fine, but audio was inoperable. We're told that Apple and DisplayLink are working on this.
The Targus USB 3.0 SuperSpeed Dual Video Docking Station with Power is a one-cable solution for today's port-shy ultra-portables and tablets that's easy to install and gives well-connected power users a quick and easy way to hit the road and quickly return to productivity. It's also a low-cost hedge against the obsolescence of proprietary docks. Drivers are backward compatible with Targus' original USB 3.0 docking stations introduced last year.
