Windows XP - Notebook Abnormal Video
Use this checklist to troubleshoot video problems other than No video.
- A brightly lit area can affect the ability to complete some of the listed procedures.
- Perform these procedures at an inside location with normal lighting.
- Position yourself directly in front of the display.
- Lines or Dark Spots are seen on the display
- Large areas of the screen appear darker than other areas
- Display appears to be dim
- Resolution Too Small or Too Large
- Restart the computer.
- For any open applications, save changes and close the application.
- Click Start, click the arrow next to the lock icon, then click Restart. The computer exits Windows, then restarts.
- If computer does not restart, press and hold the power button until the computer turns off (about five seconds), then press it again to turn the computer back on.
- Check for vertical or horizontal lines. Vertical or horizontal lines that are always seen at the same location on the screen indicate that one or more of the display panel's column or row drivers has failed (stuck in an active state). Contact technical support for assistance.
Note: The clarity of the lines depend upon the contrasting background provided by current screen activity. For example, red line sections disappear when the adjacent screen areas are red, but the lines are always present.
- Check for dark spots. Dark spots that are always seen at the same location on the screen indicate display panel damage. The dark spots are more clearly seen on a lighter colored background. Contact technical support for assistance.
- Check for pixel defects. Pixel defects are defined by the amount and location of defective pixels or dots on the display. Contact technical support for assistance.
- Adjust the brightness to its highest level.
Make sure the notebook is not running on battery power. If the notebook is running on batteries, and the BIOS Setup Auto Dim option is enabled, LCD brightness will be reduced.
If the display remains unacceptably dim at its highest brightness level, contact technical support for assistance.
- On most notebooks, this is a FN+F8 keystroke.
- If necessary, reference the Product pages or Users Guide for instructions on how to adjust this setting.
Check display resolution.
- Minimize or close all Windows.
- If display size is only abnormal in an application:
- Check the view settings in the application.
- Check the control/mouse wheel zoom feature.
- If desktop display resolution is not normal:
- Right-click on the desktop, then select properties.
- In the Display Properties dialog box, click the Settings tab.
- On the Settings tab, Display Settings, in the Screen Resolution section, Click and drag the slider to the desired resolution.
- Click Apply and check the display.
