Why is my Samsung Monitor screen blank and won't turn on?
- JJulie SpearsAug 9, 2025
A blank screen or failure to power on can occur due to several reasons. First, ensure the power cord is securely connected. If a 'Check Signal Cable' message appears, verify the cable connecting your PC to the monitor and recheck the input signal by pressing the /SOURCE button. If you see a 'Not Optimum Mode' message, your graphics card's signal exceeds the monitor's maximum resolution or frequency; adjust these settings accordingly. Also, if the power LED blinks every second, the power saving function is active – click the mouse or press any key. Finally, if using a DVI cable, reboot your PC with the cable connected, as some graphics cards may not output the video signal otherwise.
