Dell P2412H monitor not going into power save mode when connected to a DVI port on the Dell E-Port Advanced Port Replicator (APR)

The Dell P2412H monitor may experience issues going into power save mode when connected to a DVI port on the Dell E-Port Advanced Port Replicator (APR)

The Dell P2412H monitor may experience issues going into power save mode when connected to the DVI port on a Dell E-Port Advanced Port Replicator. When setting the computer to go to sleep mode, the message "Entering Power Save Mode" appears for a moment, the screen goes black, then the message appears again. The screen continues cycling between this message and a blank screen until the mouse or keyboard is used, with the monitor never successfully entering sleep mode. This problem has been observed only on the above configuration--when the monitor is connected to the DVI port on the Dell APR/Docking station.

Suggested workarounds to resolve the issue

The cause of the issue appears to be an incompatibility in specifications between the DVI interface on the monitor and the Dell E-Port APR. There are no planned updates to these specifications which will address this particular issue. The following workarounds will work to resolve the issue:

• Adjust the Power Options within Windows to prevent the system or monitor from entering sleep mode:
  
• Try a different connection on the docking station (using either a DVI-to-VGA or DVI-to-DisplayPort adapter):
  
• Replace the monitor with a model that works with the DisplayPort or VGA connection on the E-Port APR.
