Note
To change the resolution or color depth for WIN-OS/2, use the ThinkPad Features program in WIN-OS/2.

Attaching an External Monitor

To attach an external monitor:

1. Change the display output type (where to display the computer output) as follows so that you can see the computer output on the external monitor:
   

   Note: You can use the Fn key function (Fn+F7) or PS2 SC command to change the display output type.

   1. Start the ThinkPad Features program.

   2. Click on each of the following icons:

      • The CRT () icon to display information on the external monitor.

      • The Both () icon to display information on both the LCD and external monitor.

      • (The LCD () icon to display information on the LCD.)
      
      

      Attention: Do not attach an overhead projector or any office equipment other than a monitor. Otherwise, the computer might be damaged. When you select Both, do not attach an external monitor that supports only VGA mode (640-by-480 resolution). Otherwise, the screen size looks smaller, or the external monitor screen will be scrambled and the output will not be displayed (or the screen might be damaged).

2. Set the monitor type and the display driver: (Ref #32.)  

   1. Click on the Display ( or ) icon in the ThinkPad Features program.

      Note: Refer to the specifications for your external monitor to determine its supported resolutions and refresh rates.

   3. Restart the computer to make the changes effective.

   Hints
   When you are using OS/2 or Windows, the virtual screen function is available with the ThinkPad Features program. You can display a part of the high-resolution screen image that is produced by the computer. Other parts can be seen by moving the screen with the TrackPoint III or other pointing device.

3. Connect the external monitor to the computer:

   1. Turn off the computer.

   2. Attach the external monitor to the external monitor connector ( ) at the rear of the computer and then to the electrical outlet.

   3. Turn on the external monitor and the computer.

When Changing the Display Settings
