Three Monitor Setup on E6420

by Beast8161 / June 8, 2012 1:16 AM PDT

I am trying to set up my laptop to use two (2) external monitors. I am using a Dell Latitude E6420 laptop that has an external VGA connection as well as an HDMI connection. Currently I am able to use the laptop LCD screen as one display and an external monitor connected to the external VGA connection on the laptop. I would like to, if possible, connect a second external monitor to the HDMI connection. The monitor I have has an HDMI connection on it and when I connect it to the laptop, I am unable to get it to work on the 3rd (HDMI connection) monitor yet it will output to the laptop LCD and the external VGA connected monitor.
Is there a way to get it to output to the HDMi connected monitor as well? Do I need third party software to accomplish that? The laptop is running Windows 7 Enterprise 64 bit. It is on a company domain but access is not a problem (I have domain administrator access if necessary).

So far you get TWO

All laptops unless they specify 3 monitor support are dual display capable. The LCD in the laptop is one and the external is number two.

To get a third display I add some USB display card.

External Monitors

DVOn a Dell Latitude laptop, to use more than a single external monitor you need a docking station.
The docking station for the e6420 has 2 HDMI, 2 VGA and 2 DVI connections.
The maximu displays you can use is 2 at any one time.

I hope this helps

I run into that when folk try a "clean install." That is, they don't have the OS install plan from the maker.

This area is full of issues such as not only what drivers to install but in what order. I don't have that detail here so be sure to ask Dell what a proper install of Windows would entail.
