How to Fix LG Monitor “No Signal Entering Power Saving Mode Shortly” Error

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:

  1. Open Menu on your monitor.
  2. Select Settings.
  3. Under General, select Automatic Standby and disable it or change its value to maximum. See the screenshot below:

Quick fixes didn’t work? Confirm your monitor input source, restart the monitor, or factory reset it.

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, 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, check both ends of the cable for any damages.

2. Restart your Monitor

Here’s how to restart your LG monitor:

  1. Turn it off.
  2. Unplug the power cord from your monitor.
  3. 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.

  1. 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:

  1. Press the menu button on your monitor. This will open Settings options.
  2. Under Settings, go to General.
  3. Select the Reset to Initial Settings option and confirm the selection.
