Continuing the discussion from Plugable USB 3.0 suddenly stopped recognizing external monitors:
I just purchased a UD-3900H from Amazon, and neither of the Video Output ports work. I tried both the HDMI and the DVI Ports as well as the HDMI adaptor in the VDI Port, and nothing worked. I also notice that my Toshiba Tecra takes longer to Boot if I try to use either of the Video Ports.
I also tried to download and install the DisplayLink driver from https://plugable.com/products/ud-3900h as instructed in Step 1 of the instructions, and went to here:
Windows 10, 8.1/8, Windows 7
- The most current Plugable validated DisplayLink drivers for Windows can be downloaded here:
- [DisplayLink Windows Driver Version 9.2 M3 (DisplayLink+USB+Graphics+Software+for+Windows+9.2+M3.exe)
… but the install aborts saying that the software package appears to be corrupted or modified.
I hope this can be fixed. Thanks for your help!
