How Long Does A Pixel Refresh Take On An LG OLED TV [Explained]

If you own an LG OLED TV, you already know how impressive the picture quality can be. Deep blacks, vibrant colors, and excellent contrast make OLED one of the best display technologies available today. However, maintaining that performance requires occasional maintenance, and one of the most important processes is the Pixel Refresh.

Many users are unsure about how long a Pixel Refresh takes, when to use it, and whether it is safe for their TV. If you have ever noticed faint image retention or want to keep your OLED panel in top condition, understanding this feature is essential.

In this guide, you will learn exactly what a Pixel Refresh is, why it matters, how to perform it step by step, and how long it actually takes.

So let’s get these all!

What is a Pixel Refresh on an LG OLED TV? Why is it Necessary?

A Pixel Refresh, sometimes called Pixel Refresher, is a built-in maintenance feature on LG OLED TVs that helps preserve image quality by correcting minor display issues.

Unlike traditional LED TVs, OLED panels use self-emitting pixels, meaning each pixel produces its own light. Over time, these pixels can wear unevenly, especially if static images are displayed for long periods. This can lead to:

Temporary image retention
Slight brightness inconsistencies
Early signs of burn in

The Pixel Refresh function works by scanning and recalibrating each pixel. It evens out voltage levels and corrects inconsistencies so the panel continues to display accurate colors and uniform brightness.

This process is necessary because it helps:

Maintain consistent picture quality
Reduce the risk of permanent burn in
Extend the lifespan of the OLED panel
Fix minor image retention issues

LG TVs also perform a short automatic refresh cycle after a few hours of use, but a manual Pixel Refresh is more thorough and should only be used occasionally.

How to Perform a Pixel Refresh on an LG OLED TV [Step-By-Step]

How Long Does A Pixel Refresh Take On An LG OLED TV

To perform a Pixel Refresh on an LG OLED TV, go to Settings, open All Settings, navigate to General, then select OLED Care or Panel Care, and choose Pixel Cleaning or Pixel Refresher. Start the process and allow the TV to complete it without interruption. The screen may turn off during the process, which is normal.

Step 1: Turn On Your LG OLED TV and Access Settings

Start by powering on your TV using your remote. Once the TV is on, press the Settings button on your remote control. This will open the quick settings menu on the screen.

From here, scroll down and select All Settings to open the full settings panel. This is where you will find advanced display and maintenance options.

Make sure your TV is connected to a stable power source before continuing. A Pixel Refresh should never be interrupted by power loss.

Step 2: Navigate to OLED Care or Panel Settings

Inside the Settings menu, locate the General tab. Depending on your TV model and webOS version, you will see an option labeled either OLED Care, Panel Care, or something similar.

Select this option to access features designed to maintain your OLED display. This section includes tools like Screen Move, Logo Luminance Adjustment, and Pixel Refresh.

Take your time to explore this section because it contains several useful features that help prevent screen issues.

Step 3: Select Pixel Refresher or Pixel Cleaning

Within the OLED Care or Panel Care menu, find the option labeled Pixel Refresher or Pixel Cleaning.

When you select it, the TV will display a brief explanation of what the process does. It may also warn you that the screen will turn off during the process.

Choose the option to Start or Run the Pixel Refresh. Confirm your selection when prompted.

Step 4: Allow the Process to Run Without Interruption

Once you start the Pixel Refresh, your TV may turn off or display a black screen. This is completely normal. The process continues in the background even if the screen is not visible.

Do not unplug the TV or press any buttons during this time. Interrupting the process can cause incomplete calibration or lead to display inconsistencies.

It is best to run Pixel Refresh when you do not plan to use the TV for a while, such as before going to bed.

Step 5: Wait for Completion and Automatic Restart

After the Pixel Refresh is complete, your TV will automatically turn back on or return to standby mode.

You may notice improved uniformity in brightness and reduced image retention. If the issue persists, you can run the process again, but it is not recommended to use it frequently.

How Long Does a Pixel Refresh Take?

The time required for a Pixel Refresh depends on the type of refresh cycle being performed.

There are two main types:

The short automatic refresh cycle usually takes about 5 to 10 minutes. This happens automatically after every few hours of accumulated use and does not require user intervention.

The manual or full Pixel Refresh takes significantly longer. In most cases, it takes about one hour, although it can sometimes extend up to 90 minutes depending on the model and panel condition.

During this time, the TV may appear to be off, but the process is still running in the background.

If you are running a full Pixel Refresh, plan and ensure the TV remains powered and undisturbed until the process completes.

Tips for Pixel Refresh on an LG OLED TV

To get the best results and avoid unnecessary wear on your OLED panel, it is important to follow some best practices.

Only run a manual Pixel Refresh when needed. Frequent use can contribute to panel wear over time.

Use it if you notice persistent image retention or uneven brightness that does not go away after normal viewing.

Allow the TV to complete its automatic refresh cycles. These smaller cycles are designed to maintain the panel without user involvement.

Avoid unplugging the TV immediately after turning it off. The TV may perform a short refresh cycle after shutdown.

Keep your TV in a well-ventilated area. Heat can affect panel performance and longevity.

Use built-in features such as Screen Shift and Logo Brightness Adjustment to reduce the risk of burn-in.

FAQs

Is Pixel Refresh safe for my LG OLED TV?

Yes, Pixel Refresh is completely safe when used as intended. It is a built-in feature designed to maintain display quality and extend panel life.

How often should I run Pixel Refresh?

You should only run a manual Pixel Refresh occasionally, such as when you notice image retention issues. The TV already performs automatic refresh cycles regularly.

Can Pixel Refresh fix burn-in?

Pixel Refresh can reduce minor image retention, but it may not completely fix permanent burn-in. It works best as a preventive maintenance tool.

Why does my TV turn off during Pixel Refresh?

This is normal behavior. The TV turns off the display while the calibration process runs in the background.

What happens if I interrupt Pixel Refresh?

Interrupting the process can lead to incomplete calibration and may not resolve display issues. Always allow it to finish.

Does Pixel Refresh affect picture quality?

When used properly, it improves picture quality by restoring uniform brightness and reducing image retention.
