Dell Lattitude E7440 Display not setting to Graphic Card

Hi Community,

I have Dell Lattitude E7440 i5, 256GB SSD, 8GB Ram

I installed new fresh windows 8.1 enterprise in UEFI and Secure mode on, and installed all drivers from dell website.

This laptop has resolution of 1920x1080 and using Intel HD Graphics 4400, unfortunately the display never went to 1920x1080. I installed all intel amt etc but no luck. Display stays big ugly as if graphic driver is not installed.

Please guys, help me where I am making mistake, what else I need to install to have actual graphical display.

I reinstalled windows 8.1 using Legacy mode aswell, this is what I am running this dell on. Nomore UEFI but still no luck for display.

Thanks,
