I have foillowed the other forum suggestions – removed DisplayLink applications, used the cleaning tool, reinstalled. Still laptop does not recognize HDMI or DVI connection. I have the zip file to send, but do not have a ticket number.
I noticed Device Manager reports for UD 3900:
Device USB\VID_17E9&PID_4323&MI_00\7&203bebea&1&0000 requires further installation.
On that note, I did not see any further installation happen after connecting the UD 3900 as the instructions suggested would happen.
I’m certainly glad to investigate further into this strange behavior. Please go ahead and send the PlugDebug ZIP file to us directly at support@plugable.com with the subject line: “Ticket #262391”
