    Hi! Let me help you.

    There may be an issue with your graphics card if you have already used 2 different HDMI cables.

    Have you tried a hard reset?

    Press and hold the Power button for 10–15 seconds until the PC turns off.

    Unplug the power cable from the PC.

    Disconnect all unnecessary peripherals (USB devices, printers, etc.).

    Press and hold the Power button for 30 seconds to drain residual power.

    Wait about 1 minute.

    Reconnect the power cable.

    Turn the PC back on.

    Try these steps in order:

    1. Make sure Windows is set to use the monitor. Press Windows logo key + P and select Extend.
    2. Check the basic hardware connection.
      • Make sure the HDMI cable is fully seated on both the PC and the monitor.
      • Since two HDMI cables already failed, also try:
        • a different HDMI port on the PC, if available
        • the same monitor with a different system
        • a different monitor with the same PC This helps isolate whether the problem is the PC, the monitor, or the connection.
    3. Disconnect extra accessories. Remove docks, dongles, adapters, and other connected accessories, then test the monitor again.
    4. Reset the graphics driver. Press Windows logo key + Ctrl + Shift + B.
    5. Restart the PC. Select Start > Power > Restart.
    6. If the monitor still shows no signal, check the display driver.
      • Open Device Manager
      • Expand Display adapters
      • Right-click the display adapter and select Properties > Driver > Roll Back Driver if the issue started after an update
    7. If rollback is not available, reinstall the display driver.
      • In Device Manager > Display adapters
      • Right-click the adapter and select Uninstall device
      • Select Attempt to remove the driver for this device and then Uninstall
      • Restart if prompted
      • Open Device Manager again
      • Right-click the display adapter and select Update driver
      • Select Search automatically for updated driver software
    8. If the screen stays blank and Windows does not appear, use Safe Mode.
      • Hold the power button for 10 seconds to shut down
      • Repeat 2–3 times until Windows enters Recovery Mode
      • Go to Troubleshoot > Advanced Options > Startup Settings > Restart
      • Press F5 for Safe Mode with Networking Then update or roll back the graphics driver from Device Manager.

    If one monitor works but another does not, the issue may be with that monitor, its input selection, or the PC’s display output support.
