Dell 7×40, e-port advanced, dual external monitors==blank screen
Posted by essjae on March 28, 2014
I recently purchased a new e7440 for an employee and swapped out her old e6410. She has an e-port+ advanced dock and 2 22″ monitors. The setup worked great for years.
Shortly after she started using the e7440 the secondary monitor seem to go to sleep. Power cycling it fixed it. I swapped the monitors around to see if it was the DVI port on the dock or the monitor. Same behavior.
I swapped out the dock for a standard e-port+, same behavior.
I finally got around to googling to see if it was just this e7440. Unfortunately, or fortunately, it’s not.
While the issue in the post was flickering, this fix resolved my issue as well
