I am using a Dell XPS laptop with a Dell Universal Dock. I have it connected to a larger monitor and it has been working fine until I plugged in a USB stick and now the laptop is fine but the larger monitor is all fuzzy and only fills the center of the screen.
I have checked all of the display properties and nothing has changed since plugging in the USB stick. I put a different monitor on and the same thing happened. It is fine on the laptop but not the larger monitor. I did run a scan of the USB stick and there are no viruses or malware. Any ideas that I could try? Sure would appreciate it.
