Chapter 4. Troubleshooting

The screen is unreadable or distorted.

Make sure that:

The display device driver is installed correctly.

The screen resolution and color quality are correctly set.

The monitor type is correct.

Incorrect characters appear on the screen.

Did you install the operating system or application program correctly? If they are installed and configured correctly, have the computer serviced.

Missing, discolored, or bright dots appear on the screen every time you turn on your computer.

This is an intrinsic characteristic of the TFT technology. Your computer’s display contains multiple thin-film transistors (TFTs). A small number of missing, discolored, or bright dots on the screen might exist all the time.
