I have a user running a Dell Latitude E7240 connect to an E-Port Replicator and 2 monitors. When the laptop is connected to the E-Port Replicator and the lid is closed the two external monitors are working fine, however once the E-Port Replicator and the lid is opened the laptop display remains blank. Alternately when the laptop is opened and in use and then placed on the E-Port Replicator and the lid is shut, nothing displays to the two monitors. The only thing that resolves this is a hard reboot when either connected to the E-Port Replicator is connected.

Also when the Laptop is connected to the E-Port Replicator, the two external monitors are working fine when you open the lid and attempt to set the Display settings from within Windows I  am not allowed to change anything on the Laptops screen as it's status remains "Disconnected" and I am unable to change anything.

Any help would be greatly appreciated.
