DisplayLink’s Latest Windows Drivers (6.1 M0)

Posted on 17. Dec, 2011 by Bernie Thompson in Windows

DisplayLink has had two major updates to their Windows driver package this fall: 6.0 M1 and the newly released 6.1 M0.

For Plugable’s USB 2.0 products with DisplayLink chips, however, we’re still recommending earlier DisplayLink Windows driver version 5.6 M1 (5.6.31870.0), because of its proven stability. For now, Windows Update will still deliver 5.6 M1 automatically when you plug a Plugable device in.

Here’s a little background on why:

DisplayLink’s newest 6.x drivers work with all DisplayLink chips (USB 2.0 and the coming USB 3.0 generation), but the primary development focus of version 6.x has been on enabling the coming USB 3.0 generation of products. Perhaps as a result, there are some minor tradeoffs for USB 2.0 generation devices.

Here are the tradeoffs we’re following:

1) On a few systems, screens may go blank after returning from a reboot or power event. The cause appears to be changes in the way display configuration information is stored with the 6.0 and 6.1 drivers – Windows and the drivers can get confused, and that confusion will persist across unplugs, reboots, etc (going back to 5.6 M1 is the solution in these cases)
2) The uninstaller on version 6.1 fails to uninstall from Windows’ Programs and Features (as a workaround, you can use the DisplayLink “cleaner” utility).
3) 5.6 M1 is the last release where DisplayLink’s logs are readable. When we hit any strange problems on a customer’s system, our ability to analyze the logs to find the underlying problems (and solutions) is one of the ways we try to provide better support for Plugable brand devices.

All that said, we run the latest drivers on nearly all of our own systems (so we can stay up to date with the latest developments), and generally they’re great. So if there are any 6.x features or fixes that are relevant to you, feel free to download and install 6.1 M0 or later to give it a try. You can always download the latest DisplayLink driver here. And we expect that with one of the coming releases, we’ll push forward our recommendation to the latest version.

For those considering the latest versions, here’s the features and fixes DisplayLink has delivered since 5.6 M1 (as of version 6.1 M0). We’ve cut down the list to just those appear to be relevant to USB 2.0 devices.

New features since 5.6 M1 (as of 6.1 M0):

- Improved video smoothness for DL-1×0, DL-1×5 and DL-3×00 series
- Improved frame rate
- Reduced CPU utilization
- DisplayLink Tray applet enhancements

(Note these are generally subtle improvements)

New fixes since 5.6 M1 (as of 6.1 M0):

Sometimes the DisplayLink screen will remain blank when the device is
re-plugged after having been disconnected during power save. (11708)

Moving a mouse over full-screen video playback causes quality to drop. (12409)

Sometimes DisplayLink screen comes on in clone mode instead of extending when
connecting the device for the very first time. (10217)

Sometimes video may freeze on DisplayLink monitor. (11333)
