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:
- 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).
- 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.
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!
