← Troubleshooting: Windows
SMSC USB graphics software is not compatible with DisplayLink and must be uninstalled before installing DisplayLink software. It is not possible to install multiple USB graphics drivers on a PC due to limitations in the Windows graphics architecture.

    • SMSC Core Graphics Software
Reboot the PC before installing DisplayLink software.

It is possible in some cases that the SMSC software leaves its services installed. To remove these:
  1. Click Start, and search for "cmd".
  2. Right-click "Command prompt", and then click "Run as administrator":
      
  3. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
  4. Type sc delete SGFXMgr and press Return.
    NOTE: if you get access denied error, it means you have not executed the command prompt as an administrator
