I have a Dell G7 laptop, UD-3900 docking station. With the USB keyboard connected to the docking station, I have a pretty frequent issue with the keyboard lagging out for a few seconds and then repeating the last letter I typed four or five times. Plugging the USB keyboard into the laptop directly resolves the issue. I’m using the latest DisplayLink drivers (installed last week) and it’s a new keyboard.
Thank you so much for reaching out to us, I am sorry to hear that you are running into this issue, but I would be more than happy to assist!
Is the keyboard you are utilizing a wired keyboard, or does it utilize a wireless dongle (such as a Logitech Unifying receiver) in order to connect to the dock?
