USB Graphics Support on Mac Gets A Double Boost

USB is the easiest way to connect one or more extra monitors to a computer, but drivers are required to make it all work.

Two events this week have made attaching multiple monitors to Mac OS X systems better:

  1. On Thursday March 14th, Apple released OS X 10.8.3, which fixed some key bugs in Mac OS X support for multiple displays. Fixes include avoiding potentially show-stopping login screen issues. Some smaller Apple bugs remain, including that drag/drop may get hung at times. A sleep/wake cycle kicks OS X out of that state. Also, as of 10.8.3 OS X doesn’t yet support USB 3.0 audio devices. So USB 3.0 docks and HDMI adapters won’t have any audio function (via USB 3.0; connecting via USB 2.0 will work).
  2. Today, March 22nd, DisplayLink has promoted their V 2.0 driver series out of beta. For the first time, DisplayLink’s driver for Mac OS X now has support for USB 3.0-generation DisplayLink devices, like the Plugable UD-3000 Universal Laptop Docking station, and Plugable USB3-HDMI-DVI Graphics Adapter. The DisplayLink drivers still do not support OpenGL applications on the USB-attached screen, but for normal web and business application use, they’re great for enabling multiple monitors and projectors on a Mac.

We’ve been testing these new releases on our Macs here, and while things aren’t perfect, these are huge steps forward, — we are really excited about the improvements.

DisplayLink’s latest Mac OS X drivers are available here.

If you have any questions, feel free to post here and we’ll be happy to help. Thanks for going out of your way for Plugable products!
