latitude e5540 with nvidia 720m gpu and intel gpu
it seems my laptop always uses the intel integrated gpu. is it possible to force use the dedicated nvidia 720m? i would prefer to use the 720m all the time

The 2013 Latitude E5440 sold with the option of purchasing the additional discrete Nvidia GeForce (N14M-GE). Your system was purchased only with the onboard Intel HD 4600 video.

thanks. so there is no way to force the 720m to be used? i had a alienware 14 recently and was able to force use the nvidia gpu in that machine (i think it was some sort of f5 toggle from memory)

The GPU is selected with the optimus control panel - but it's not a standalone, discrete GPU. It's a co-processor - - the Intel GPU will always be active and primary. By design, all video data passes through the on-CPU GPU on its way to the display -- the nVidia GPU has no physical connection to the screen.

Not on the Latitude no -- there are two ways to implement hybrid video - software-only and hardware. The Alienware likely had a true hardware hybrid -- the Latitude (and Inspiron, Vostro and newer XPS) are all software-controlled.

Hi alphabetagaga,
Using the nvidia control panel - select manage 3d settings - on global settings - select preferred graphics processor as high performance NVIDIA processor and choose apply - see the pic for reference only - http://bit.ly/1ImbYvi
Also. select the option set physx configuration - select the GeForce card applicable and apply - see pic for reference only - http://bit.ly/1eT87ul
This should render the any applications to use high performance / video memory from the nvidia card. However, this is software controlled. As advised by ejn63 - Intel card will physically still be the primary card. After you make these changes, the nvidia will be logically primary.
