Hi Hanan,

Thanks for getting in contact with us. I’d be more than happy to help you with your Plugable UD-3900 and the fuzziness you are experiencing. Since you’ve already tried reinstalling the drivers, it would be helpful to get a bit more information.

Could you please provide the logs produced by our tool Plugdebug, you can find it here and then send them to me at support@plugable.com.

Once we have those logs, we’ll start trying to figure out what exactly is going on with your setup.

Regards,
