Attaching an external monitor
Considerations for using the TV-out function
There are a few things to consider when you use the TV-out
function.
The following table shows the display modes that you can
choose when you use the television:
If you use DOS full screen (VGA mode) on television, the
screen will be blank.
If you play a video clip (AVI or MPEG file) and move the cursor
on the window, the cursor disappears under the image.
You cannot use the Fn + F7 (display switching) function when
you are in the dual display mode or when you are displaying
the image on the television and the LCD simultaneously.
To use this function with the TV as the secondary display or
the simultaneous display, you need to enable the television
settings every time you start your computer.
Note the following when the TV is the secondary display or the
simultaneous display: Because of the television aspect ratio
(screen shape), the edge of the image will be cut off even
when you set the smallest resolution.
