What to do if my Lenovo C27-40 says 'Out of Range'?
If your Lenovo monitor displays 'Out of Range', it means your system's display mode isn't supported by the monitor. If you've replaced an old monitor, reconnect it and adjust the display mode to the specified range for your new monitor. If you're using a Windows system, restart in safe mode and select a supported display mode.
