Unveiling the Black Screen Dilemma on LG Flatron Monitors


“Why does my LG Flatron W1934S monitor display the Windows login screen for a brief moment before going black? Despite resetting my computer and attempting to navigate the monitor’s menu, as well as adjusting the VGA cable, the screen remains black. What could be causing this issue?”


When your LG Flatron W1934S monitor displays the Windows login screen for a moment before going black, it can be a perplexing and frustrating issue. This problem may arise due to several factors, ranging from hardware failures to software settings. Let’s explore some potential causes and solutions.

Firstly, it’s essential to rule out any hardware malfunctions:

  • Monitor Self-Check

    : Use the monitor’s built-in self-test feature. Disconnect the VGA cable from the computer and see if the monitor displays a “No Signal” message. If it doesn’t, the monitor may require servicing.

  • Cable and Connection

    : Inspect the VGA cable for any signs of damage. Try using a different cable or connect the monitor to another computer to determine if the issue persists.

  • Software and Settings

    If the hardware seems to be functioning correctly, the next step is to examine software and settings:

  • Driver Update

    : Outdated or corrupted display drivers can cause display issues. Update the graphics driver through the Device Manager or the graphics card’s manufacturer website.

  • Power Settings

    : Incorrect power settings in Windows might send the monitor into a power-saving mode prematurely. Check the power settings, especially the PCI Express and Link State Power Management settings.

  • Monitor Settings

    Lastly, the monitor’s internal settings could be contributing to the problem:

  • Factory Reset

    : Perform a factory reset of the monitor settings through the on-screen menu.

  • Resolution and Refresh Rate

    : Ensure that the computer’s display settings match the monitor’s native resolution and refresh rate.

  • When to Seek Professional Help

    If you’ve tried all the above steps and the issue remains unresolved, it might be time to consult with a professional technician. The monitor could have an internal fault, such as a failing backlight or power supply issue, which requires expert attention.

    In conclusion, a systematic approach to troubleshooting can often resolve the black screen issue with the LG Flatron W1934S monitor. By checking the hardware, updating software, and adjusting settings, you can identify and fix the problem. However, if the monitor continues to malfunction, professional repair or replacement may be necessary. Remember, monitors, like all electronics, have a lifespan, and it may be time to consider an upgrade if your current model is aging.
