Quick Fixes
Before diving into advanced troubleshooting, try these simple quick fixes. They are easy to implement and may resolve the “No Signal Entering Power Saving Mode” message right away.
- Switch ports or cables – The issue may be as simple as a loose cable connection.
- If your monitor has multiple HDMI, DisplayPort or other input ports, connect the cable to an alternate port on the monitor.
- Inspect the video and power cables for any damage or bent pins. Replace damaged cables.
- Firmly reconnect both ends of each cable to their ports on the back of your monitor and computer. Listen for clicking sounds indicating a secure connection.
Cables connect and transmit signals between your monitor and PC. Reseating connections or swapping cables and ports can repair transmission issues causing the lost signal.
Try these effortless cable checks before proceeding to more complex troubleshooting. The problem may be a simple loose wire you can fix in seconds!
If changing cables and ports doesn’t work, try adjusting your monitor settings as well:
- Disable Automatic Standby
- Go to to your monitor’s “menu” settings displayed on-screen. For LG monitors, open the “General” tab.
- Locate the “Automatic Standby” or “Sleep Mode option“. Disable this or increase the time delay before standby.
- Check input source settings
- Open the input source menu on your monitor, found under an “Input” tab typically.
- Verify the correct port for your video cable connection is enabled. HDMI 1, HDMI 2, DisplayPort 1 etc.
- Disable ports not being actively used. The monitor may be checking inactive ports causing the lost signal error.
Your monitor settings could be initiating standby after periods of idle time or checking unconnected ports. Adjusting these can prevent the issues triggering the “No Signal” message temporarily while you address other potential root causes.
Advanced Troubleshooting
If you’ve tried the quick fixes with no luck, it’s time to dig deeper:
- Restart the monitor
- Locate the power button on your LG monitor and press to turn it off.
- Unplug the power cable from the back of the monitor.
- Wait 30 seconds then reconnect the power cable.
- Turn your monitor back on with the power button.
This power cycling forces your monitor to fully reboot its internal components. Reseting things can clear any software issues causing the missing signal error.
- Factory reset

- Locate and select the option to Reset to Initial Settings/Factory Reset.
- Confirm the reset when prompted to restore default values.

Restoring to factory conditions returns software and display settings to their origin state. This wipes any problematic customized values that could be triggering issues.
