Digital on ThinkPad is the Mini DisplayPort on your computer. Digital 1 on dock and Digital 2 on dock are DisplayPort or DVI connectors on a docking station. The Integrated Graphics mode will achieve longer battery life. The Discrete Graphics mode enhances graphics performance. When NVIDIA Optimus is selected, the system automatically switches between discrete graphics mode and the integrated graphics mode depending on the running program. Note: NVIDIA Optimus should be selected only if you are using a Windows 7 model. The system BIOS automatically switches the Graphics Device setting to NVIDIA Optimus if the operating system supports the feature, and to Discrete Graphics if the operating system does not support it. 116 User Guide
