Hi James
Firstly, thanks for getting back with suggestions to try - here's what I did:
1.
Disconnect your dock
Unplugged USB cable from PC
2.
Uninstall DisplayLink software http://www.displaylink.com/downloads/sla.php?fileid=165
I logged in as an admin capable account and used windows 7 'programs and features' to uninstall the 'DisplayLink Graphics'. I allowed the uninstaller to shutdown programs as it requested, and allowed it to immediately reboot the PC. After the reboot both the 'DisplayLink Graphics' and 'DisplayLink Core Software' items had been uninstalled from 'Programs and Features'
3.
Run the cleaner tool from here http://www.displaylink.com/downloads/sla.php?fileid=121
I downloaded and unzipped this file, and then did a 'run as administrator' on EndUserCleaner.Exe v2.4.51572.0. This completed successfully. I then rebooted the PC again.
4.
Install DisplayLink software
I then installed via run as administrator the latest software v7.9M2 again as downloaded from
http://www.displaylink.com/downloads/sla.php?fileid=165. When prompted during the installation process I reconnected the dock via USB3 and all drivers installed without any errors. The install completed successfully and then I rebooted the PC.
5.
Reconnect your dock
Despite disconnecting and reconnecting, and powering the dock on/off both connected and disconnected form the PC, the symptoms are unchanged from before. That is, it has never worked with the external monitor on the DisplayPort connector of the Dock even though the monitor is recognised fully by Windows (can see model number details via data interrogation of the monitor) and it's power status can be controlled by the DisplayLink software (choosing off makes it go into standby; choosing extend-left makes it wake up but screen stays black, no mouse cursor or anything).
So, unfortunately it is still
not working and has
still never worked.
I've re-run the advanced diagnostics tool again and attached the new zip file.
What do you suggest to try next, please?
thanks
Malcolm
