Monitor Specific Troubleshooting

Self-Test Feature Check (STFC)

Your monitor provides a self-test feature that allows you to check if your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cable from the back of computer.
  3. Turn on the monitor.

The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.

  1. This box also appears during normal system operation if the video cable becomes disconnected or damaged.
  2. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.

If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

OSD Warning Messages

A warning message may appear on the screen indicating that the monitor is out of sync range.

Cannot Display This Video Mode

This means that the monitor cannot synchronize with the signal that it is receiving from the computer. Either the signal is too high or too low for the monitor to use. See Specifications for the Horizontal and Vertical frequency ranges addressable by this monitor. Recommended mode is 1024x768 @ 60Hz.

Occasionally, no warning message appears, but the screen is blank. This could also indicate that the monitor is not synchronizing with the computer or the monitor is in a power save mode.

The following error messages are specific to Windows 2000 and Windows NT 4.0 systems only and appear in the system error log:
Not enough memory is available for device \Device\PointerPort0

 

The driver failed to allocate non-paged memory. This is an indication of very low memory resources. The driver does not use much memory so it is likely that some other driver is the culprit. It is recommended that you try to configure more memory.
Too many PointerPort devices are defined. Could not create device: \DosDevices\MtsTch0.

There is a large upper limit (about 64) on the total number of pointing devices (mice, tablet, touch screens) supported by the 3M Touch Systems driver. It is recommended that you use fewer pointing devices.
Could not create DeviceMap entry for device \Device\PointerPort0


The driver failed to make an entry in the registry that identifies the driver to the operating system. This may indicate a corrupt registry. Use your Emergency Recovery Disk to restore the registry.
Could not create symbolic link for device \Device\PointerPort0


The driver failed to make an entry in the registry that identifies the driver to user applications (i.e., the control panel). This may indicate a corrupt registry. Use your Emergency Recovery Disk to restore the registry.
