  First, verify that the power cord is correctly connected to the power outlet. Also, check the signal cable between your PC and the monitor to ensure it's properly connected. If the signal from your PC is out of the display's horizontal or vertical frequency range, consult the 'Specifications' section of the manual to reconfigure your display. You can unlock the OSD controls by entering the OSD lock menu and changing items to off. Check your Control Panel display settings to see if the frequency or resolution were changed, and readjust the video card to the recommended resolution, ensuring you select the recommended resolution. If the video card doesn't support the resolution, contact the computer or video card manufacturer.

  First, ensure the signal cable is properly connected, using a screwdriver to tighten it if needed. Make sure the video card is correctly inserted in its slot. Set the color setting higher than 24 bits (true color) via Control Panel settings. If the screen is set to interlace mode, change it to the recommended resolution. Also, ensure the video card supports Plug&Play function. If the selected resolution is HDMI 1080i 60/50 Hz, the screen may flicker; change the resolution to the recommended 1080P.
