What to do if my LG L203WT displays 'OUT OF RANGE' or 'CHECK SIGNAL CABLE'?
- TTerry PrattAug 15, 2025
If your LG Monitor displays an 'OUT OF RANGE' message, it means the signal from your PC's video card is outside the monitor's supported horizontal or vertical frequency range. Refer to the 'Specifications' section to reconfigure your display settings. If you see a 'CHECK SIGNAL CABLE' message, the connection between your PC and the LG Monitor is loose. Ensure the signal cable is properly connected. Also, verify the power cord is correctly connected to the power outlet and that the monitor is powered on by pressing the Power button. Adjusting the brightness and contrast may also help. If the monitor is in power saving mode, try moving the mouse or pressing any key to wake it. Finally, ensure your PC is turned on. If the power indicator is amber, it could also indicate a power issue.
