Latitude E7240 - Dual External Displays Without Dock?

Hi ag-asanchez,

The Latitude E7240 uses an Intel HD Graphics 4400 GPU and so can support up to 3 independent displays, not on dock. In order to use both the onboard screen and 2 external displays both the HDMI and MiniDisplayPort will need to be connected to external displays.

With the Intel Driver, 9.18.10.3204, installed and two external displays connected, the following option should enable 3 independent displays.

(from the notification panel)

Intel HD Control Panel >> Output to >> Extended DT (options here for clone or extended)

Please see the following Intel guides for more information regarding a multiple display set up for the 4400 GPU.

Thanks,

I successfully connected a monitor and a digital projector to the Dell Latitude E7240 using the HDMI port and the Display Port at the same time. The system recognized the three displays and allowed me to extend my desktop between the three displays. I was also able to customize the displays with their individual resolutions and placement.

Did you get this working ? and What was the maximum resoluton ? I am considering buying a New monitor and i want to determine if i go QHD or 4K
