While using a UGA-4KDP that is setup to be the Main Display on Windows 7 64 bit, the display does not show up after a computer restart, I need to unplug/replug the USB connector of the UGA-4KDP after the computer restart and then the display will appear. Any suggestions how to remedy to that ?
Setup: Intel i7 IvyBridge with Intel HD 4000
Thanks in advance
Thanks for posting. I’m sorry to hear about the troubles with your adapter. I’d be happy to help!
The best first step is to ensure the latest DisplayLink driver we recommend for Windows 7 is installed and working properly. We’ll do this by performing a clean installation of the driver. Please follow these steps:
- Disconnect the adapter from the system and please keep it disconnected until the last step.
- Uninstall the DisplayLink Core software from the Control Panel -> Programs and Features.
- Download, extract and run the DisplayLink cleaner tool, found here –> http://displaylink.com/support/sla.ph…
- Once the Cleaner has been run, reboot (even if not prompted to)
- Now download and install the 7.8 M0 DisplayLink software, found here –> http://www.displaylink.com/downloads/…
- Reattach the adapter to your system when prompted by the installer which will trigger the final portion of the installation, and then test rebooting with the adapter connected again.
Please let us know if that helps, and we can go from there.
Hello Bob, here is what I have done:
- Disconnect the adapter
- Uninstall the DisplayLink Core software from Control Panel (v7.7.57957 was installed)
- Run the cleaner tool.
- When trying to install the 7.8 M0 DisplayLink software it did not work. I can see briefly the following screen for about 2 seconds, then it disappear and nothing else happens !](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1266077/Image1_inline.png?1440709048)](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1266077/Image1.png?1440709048)
- I have downloaded the Support tool and made a zip file. Let me know if you want me to send it to you.
Thanks for getting back, and thanks for running our PlugDebug program. Please send the file to email@example.com with ‘Ticket 116230’ in the subject line so we can match everything up. Once we have the file we can determine the next steps from there.
Just a quick update for anyone following this thread, Pierre was able to troubleshoot this issue successfully on his own while we were assisting him.
Pierre had Windows 10 on the system originally and reverted back to Windows 7. When he encountered this issue he ran the ‘Troubleshoot compatibility’ wizard on the DisplayLink driver installation package and the error: 0x80070057 was displayed. When he searched Google for the error it pointed him in the direction that the error could be caused by a problem with the environment variable having to do with the Windows TEMP location. When he made the change as described here --> " ‘Advanced system settings’ -> Advanced Tab -> Environment Variable: I changed the definition of TEMP and TMP to C:\Temp" and rebooted he was able to install the driver.
Our belief is that the previous ‘%USERPROFILE%\AppData\Local\Temp’ directory was corrupted or had permissions broken during the OS change from 10 to 7 and caused the installer not work. We would like to thank Pierre for his great efforts in finding the root cause in this case and sharing it with us.
