Connecting a projector or an external monitor
This topic provides information about connecting a projector or an external monitor.
Using an external monitor
Note: When you connect an external monitor, a video interface cable with a ferrite core is required.
Your computer can support a maximum video resolution of up to 2048x1536 (with an external monitor
connected to the VGA connector) or up to 2560x1600 (with an external monitor connected to the mini
DisplayPort connector), provided that the external monitor also supports that resolution. For more
information about the external monitor, refer to the manuals provided with the external 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
pointing device or another pointing device.
In the Display Settings window, you can move the display output to the computer display, the external
monitor, or both.
