Thanks for posting - I understand, and yes you can do that.
The UD-160-A dock you have (http://plugable.com/products/ud-160-a ) has independent controllers for the display, ethernet, audio, and hub. So you can disable one without disabling the others.
What I’d recommend is two steps:
- Disable the USB Graphics device in device manager
To do this, hit the Windows-R hotkey and type devmgmt.msc. Find the “Plugable UD-160-A” entry under “USB Display Adapter”. Right click to bring up the menu for that device and select “Disable”
Disabling the device first will stop Windows Update from re-installing the driver later.
- Uninstall “DisplayLink Core Softare” from Windows Programs and Features.
To do this, hit the Windows-R hotkey and type appwiz.cpl. Find the entry for “DisplayLink Core Software” and hit uninstall.
This will completely uninstall the DisplayLink software.
Only the DVI port on the UD-160-A will be disabled … everything else will continue to work as usual.
Note that on our USB 3.0 docks like the UD-3000 (http://plugable.com/products/ud-3000/ ) the situation is different – for USB 3.0, the DisplayLink chip also provides the Ethernet and Audio functions, so we can’t just uninstall the DisplayLink software in that case.
My apologies for the frustration. But thanks for asking and hope that helps!
