Considerations for attaching an external monitor

•When installing an operating system, you must install the display driver for your monitor that is supplied with the computer, and the monitor INF file that is supplied with the external monitor.

•If you set a resolution higher than the resolution you are using on the computer monitor, and use an external monitor that does not support that resolution, take advantage of the virtual screen function, which enables you to display only a part of the high-resolution screen image your computer produces. You can see other parts of the image by moving the screen with the TrackPoint pointing device or another pointing device.

•If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.
