Hello,
I have an issue where the primary and secondary monitors appear to switch rapidly and continuously. This occurs after connecting my laptop to an external dock connected via DVI-D to a Dell U2713HM monitor.
The dock is a HP USB 3.0 universal. The laptop is a HP ENVY TS m7. The latest drivers are installed and Windows Update is current.
I've placed a short snippet of the issue
here. Notice the desktop background image keeps switching between the monitors.
Any ideas as to what may be causing this? I did reseat the connections.
