Your computer can support a maximum video resolution of up to 2048x1536 (with an external monitor attached to the CRT connector) or up to 2560x1600 (with an external monitor attached to the DisplayPort connector), provided that the external monitor also supports that resolution. For more details, refer to the manuals provided with your monitor.

You can set any resolution for either the computer display or the external monitor. When you use both at the same time, the resolution of both is the same. If you set a higher resolution for the computer display, you can see only part of the screen at a time. You can see other parts by moving the image with the TrackPoint or another pointing device.

You can move the display output to the computer display, the external monitor, or both in the Display Settings window (in Windows XP, Display Properties window).
