Why does my AOC L1740 display 'Check Video Cable'?
- DDesiree YoungJul 29, 2025
The 'Check Video Cable' message on your AOC Monitor indicates that the monitor video cable is disconnected. To resolve this, connect the 15-pin monitor video cable to the VGA connector on your computer, ensuring the computer is powered off during the connection.
