NVidia N14M /Intel HD 4x00 hybrid GPU equipped systems:
#Intel graphics and media control panel change resolution plus
Note: An E-Port Plus II Advanced Port Replicator (APR) may be required to have DisplayPort or DVI graphics ports available. This is supported by both the Intel Integrated 4x00 HD GPU (video card built in to the processor) and the nVidia N14M GPU (separate dedicated graphics processor) options. Older or economy displays may not have high resolution capabilities od 1920 x 1200 or higher.īoth the Latitude E5540 and the Latitude E5440 support the connection of a 2nd external display directly to the system via either the High Definition Multimedia Interface (HDMI) port on the left side of the chassis or the Video Graphics Array (VGA) port on the right side of the chassis. In all resolutions below 1920 x 1200 the limiting factor for display resolutionis normally the display capability of the display you have connected to the dock. (E-Port DVI connections are limited to 1920 x 1200 for example.) If you extend the desktop, the optimal resolution for each display should be displayed (EXAMPLES:1920 x 1200, 1680 x 1050, 1440 x 990) unless you displays native resolution exceeds that port capability of the video port. If the external display is a higher resolution than the internal LCD, the external display should scale to the internal display resolution in a clone mode.
Note: If you connect an external display that cannot scale to the resolution of the internal LCD (1366 x 768 or 1600 x 900), if you clone the displays, the internal LCD will scale to the lower resolution of the external display (EXAMPLE: 1024 x 768), 1200 x 800).
