When you connect an external monitor and turn on the computer’s power the computer automatically recognizes the monitor and determines whether it is color or monochrome.

You do not have to make any settings to use an external monitor. However, you can select from the following options:

External monitor only

Internal LCD only

Simultaneous display on the external monitor and internal LCD

The TSETUP program has two options Simultaneous and Internal/External. If you select Simultaneous, displays appear on the internal LCD and external monitor at the same time. If you select Internal/External, press hotkey combination Fn + F5 to change from internal LCD to external monitor to simultaneous.

CAUTION

Do not press Fn + F5 under the following conditions:

1.While running data communications, an error could occur. Wait for completion of the data transfer.

2.While running a DOS session under Windows, the screen will be blanked. If you do press Fn + F5 in a DOS session, type exit to return to Windows.
