In most cases, simply switching the ports or disabling automatic standby in monitor’s settings will fix the “No Signal Entering Power Saving Mode” error on your LG monitor.
For example, if you initially plugged the cable into HDMI port 1, try plugging it into the second port instead. If your monitor only has one HDMI port, use its DisplayPort.
Changing the ports didn’t solve the problem? Don’t worry! Another quick fix is to disable Automatic Standby feature in your LG’s monitor setting. Here’s how to do that:
- Open Menu on your monitor.
- Select Settings.
- Under General, select Automatic Standby and disable it or change its value to maximum. See the screenshot below:
1. Check Input Source
Make sure that the correct port is selected as the input source.
For example, if you have connected your PC or laptop through HDMI or DisplayPort to your LG Monitor, then you must select the respective option in the input setting.
Most LG monitors have multiple USB-C or HDMI ports, so note the port number that you have connected your device to and select the same as input source.
You can access the Input Source setting on your LG Monitor using its on-screen controls.
If your LG monitor comes with a joystick, just press it once to open its setting menu.
If you have the correct input source selected and your LG Monitor still displays the error message, may be your HDMI or DisplayPort or USB-C cable (whichever you are using for connection) is faulty.
So, check both ends of the cable for any damages. Also inspect the power cable of the monitor. If it is damaged, it won’t provide enough power to the monitor to work properly.
2. Restart your Monitor
- To restart your LG Monitor, first, turn it off.
- Unplug the power cord from your monitor.
- When the monitor is unplugged, press and hold the Power button on the monitor for 30 seconds to clear its cache.
- If your LG monitor comes with a joystick, press and hold it for 30 seconds.
- Wait for 2 minutes, and then plug it back in.
3. Factory Reset your LG Monitor
If none of the above works, the last workaround is to reset your LG monitor. To reset it, press the menu button on your monitor. This will open Settings options.
Under Settings, go to General and select the Reset to Initial Settings option and confirm the selection.
If you have followed all the above steps, but your LG monitor is still stuck on No Signal … error, then there is the possibility that your monitor may malfunction. In that case, contact LG support for assistance.
