Color incongruity on a DVI LCD monitor can be caused by a variety of issues, including hardware failure, configuration issues, or display settings.

First, hardware failures can cause color incongruities. For example, if the color palette of the monitor is damaged or aged, it may cause color inconsistency on the monitor. In addition, failures in the monitor's lamps, power supply, or other hardware components can cause color incongruities. If there is a hardware failure, the corresponding component of the monitor may need to be replaced or repaired to correct the problem.

Second, configuration issues can also cause color incongruities. For example, if the resolution of your computer or monitor is not set correctly, this can cause color issues. Additionally, the monitor may require updated drivers or firmware to ensure compatibility with the computer. Fixing configuration problems may require adjustments through the monitor's and computer's settings menus or the operating system's control panel.

Finally, display settings can also cause color incongruities. For example, choosing an incorrect color profile in the monitor settings, or not properly calibrating the monitor can cause color incongruity. In addition, the monitor may need to select different display modes according to different scenarios or applications to achieve the best results. Troubleshooting display settings may require making adjustments by navigating through the monitor's or computer's menus, or by calibrating the monitor with a professional display calibration tool.

In summary, color incongruity on DVI LCD monitors can be caused by hardware failure, configuration issues, or display settings. In order to solve these problems, it is necessary to troubleshoot the problems one by one and make correct adjustments and repairs.
