nVidia’s latest Win7/Vista drivers (October 18, 2010 and later) conflict with existing DisplayLink drivers (version 5.5 Sept 29th and earlier), causing video playback and some 3D applications to not function. These problems apply to all DisplayLink-based USB graphics products, including ours.
DisplayLink is working to fix the conflicts. They’re trying to roll out updated drivers as quickly as possible, but have some work to do yet.
On Nov 15 they made available a maintenance release of the older DisplayLink driver version 5.4, called “5.4 M1”, which resolves some of the conflict, but not enough to make the solution workable.
Our recommended solution for now is to use the latest DisplayLink drivers, and stay on or move back to nVidia drivers version 258 or earlier. For Windows 7 and Vista 32-bit, you can find the nVidia drivers here. For 64-bit, find them here. These drivers do not have any of these these 3D & video playback conflicts.
Our apologies to users affected by these conflicting drivers. We hope this information helps. Feel free to email email@example.com or visit http://plugable.com/support/ and post a question if you have any remaining problems. Again, thank you![updated 11/23]
