The image on the external monitor does not fill the screen.

You are using an external monitor and simultaneously displaying an image on the computer display.

This is typical; no action is required.

Small red, green, or blue spots appear on the computer TFT display.

Small spots, called on-pixels, often	This is typical; no action is required.
appear on TFT screens. Compaq
limits the number of these on-pixels
to 0.003% of the approximately
1 million transistors that are on a
12.1-, or 11.2-inch display.

When in MS-DOS mode, the image on the computer display does not fill the screen.

When displaying simultaneously, the image on the external monitor may not be centered.

To maintain a high-quality image, the 800 × 600 models do not stretch the lower-resolution image of MS-DOS mode to fill the screen.

This is typical; no action is required.

Solving Software Application Problems

Most software application or installation problems occur as a result of one or more of the following:

■The application was not installed correctly.

■Memory was not allocated correctly.

■A conflict exists between applications.
