I have a Dell Latitude E6420 and recently got a Dell Monitor P221 2H. The issue is that the Laptop is not detecting the external monitor and Monitor is displaying "Entering Power save mode".
I tried connecting it through the VGA cable that came with the monitor and also tried with a DVI-D cable to connect but no success.
I tried going to control panel->Display and tried the option to detect and identify but nothing on the monitor.
The display adapter shows Standard VGA Graphic Adapter if it helps.
What i am missing and how can i get my external monitor working with my laptop. Any help will be highly appreciated.
EDIT::
--> I tried using both docking station(DVI-D) and connecting directly to laptop(VGA port in this case).
--> Pressing Fn + f8 did not help(nothing happened in this case).
--> I have latest display drivers.
--> Laptop has BIOS version A08 (did not updated this as this is the latest for my laptop)
--> Using Windows 7 64 bit
Fn
+F8
to cycle through the displays? Have you updated the BIOS? Have you made sure you have the latest display drivers? What OS are you using?
