Video resolution support issues with W520

Post  RickL on Wed Feb 19, 2014 11:06 am

It's been reported that Intel graphics lack video performance and specific resolution support.  By changing following video settings in the BIOS will force NVIDIA discrete graphic as primary/only video output device.  This should improve video performance and will support additional resolutions.

Press "F1" function key during post screen to access BIOS.

Select "Config" Tab and then Select "Display" option

Set following two options:

Graphics Device:  Discrete Graphics
OS Detection for NVIDIA Optimus:  Disabled

Note:  All laptops with dual GPUs (with discrete GPU and Intel 2nd Gen or newer CPU) face similar issues (example: E6520).  They should all be set to discrete graphics.
