Solving Screen Problems Continued

Problem

Screen is blank

(continued).

Computer screen is blank and the screen on an external monitor displays information.

Probable Cause

You disconnected an external monitor while the computer was on or in Suspend, and the settings for resolution and colors are not the same for both displays.

Display was switched to the external monitor.

Solution(s)

If the Fn+F4 hotkey does not switch to the internal display, restart the computer.

Press the Fn+F4 hotkey to display information on the computer screen.

Display on an external monitor is distorted.

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

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

Incorrect display device drivers are installed or incorrect resolution is set.

The external monitor is not Energy Star compliant, but the Computer Setup Power Saving Monitor option or the Windows Energy Star compliant option is enabled.

Small spots, called on-pixels, often appear on TFT screens. Compaq limits the number of these on-pixels to 0.003 percent of the approximately

1 million transistors that are on a 10.4-inch display.

By default, 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.

Double-click the Display icon in Control Panel, click the Settings tab, and set the correct display type and resolution for the external monitor.

1.Press any key or move the pointing device to restore the display.

2.If display remains distorted, turn the monitor off, then on again.

3.Disable the Computer Setup Power Saving Monitor option and the Windows Energy Star compliant option.

This is typical; no action is required.

If Fn+T does not clear the problem, contact your authorized dealer or reseller.
