How to Fix Lines or Marks on Your LG OLED Monitor Using Image Cleaning
If your premium display is showing distracting streaks or image retention, running a built-in maintenance cycle can quickly restore picture quality. Fixing lines or marks on your LG OLED monitor using the Image Cleaning feature clears temporary artifacts by recalibrating the screen's individual pixels. Accessible through the monitor's on-screen display menu under OLED Care, this automated process takes up to 10 minutes to run while the screen is off, effectively refreshing the panel and protecting your investment from long-term burn-in.
Why Are There Lines or Marks on the Screen?
If static elements such as the Windows taskbar, icons, or game menus remain on the screen for an extended period, the affected pixels may develop temporary image retention.
Temporary marks may appear after you move the monitor or when the room temperature changes significantly.
How to Run Image Cleaning
Step 1. If Your Monitor Does Not Have a Remote
Use the joystick button on the monitor to open the settings and run Image Cleaning.
Press the joystick button on the back or at the bottom center of the monitor to open the on-screen menu.
Move the joystick to open Settings.
Select OLED Care, and then select Image Cleaning to start the process.
Step 2. If You Have a Remote with an OLED Care Button
Press the OLED Care button on the remote.
Select Image Cleaning from the on-screen menu, and then select Yes.
When the confirmation message appears, select Yes again.
Step 3. If You Have a Remote with a Dial Button
Press the Dial button in the center of the remote.
Select OLED Care from the circular on-screen menu.
Select Image Cleaning, and then select Yes. When the confirmation message appears, select Yes again.
Step 4. Still need help?
If the issue persists after following the steps above, you can get further support through LG Chatbot on our website or by requesting a technician visit.
(Note: A service fee may apply if your product is out of warranty.)
