As an LG OLED TV owner, you’re likely aware of the importance of maintaining your screen’s health and longevity. One crucial aspect of this maintenance is pixel refresh, also known as pixel refresher or image retention compensation. But how often should you perform this crucial task? In this in-depth article, we’ll delve into the world of OLED technology, explore the reasons behind pixel refresh, and provide you with a comprehensive guide on how often to do it on your LG OLED TV.
Understanding OLED Technology and the Need for Pixel Refresh
Before we dive into the recommended frequency for pixel refresh, it’s essential to grasp the inner workings of OLED (Organic Light-Emitting Diode) technology. Unlike LED/LCD TVs, which use a backlight to illuminate liquid crystals, OLED panels consist of millions of individual pixels that emit their own light.
This results in several advantages, such as:
- Infinite contrast ratio, leading to true blacks and richer colors
- Wider viewing angles, making it perfect for shared viewing experiences
- Fast response time, reducing motion blur and making it ideal for fast-paced content
However, OLED’s technology comes with a minor drawback: image retention. Also known as burn-in, this occurs when static images or graphics are displayed for an extended period, leaving behind a faint, permanent impression on the screen.
What Causes Image Retention on OLED TVs?
Image retention is more likely to occur under certain circumstances:
- Stationary graphics or logos, like channel logos or video game menus, that remain on screen for hours or days
- Static images, such as video game HUDs (heads-up displays) or TV menus
- Incorrect TV settings, like excessive brightness or contrast
- Insufficient screen timeouts or power-saving features
Purpose of Pixel Refresh: Why It Matters
Pixel refresh is a feature designed to combat image retention by periodically shifting the pixels to a different color or intensity, ensuring that no single pixel is stuck in the same state for too long. This process helps to:
- Reduce the risk of permanent image retention
- Maintain a balanced wear of pixels, prolonging the lifespan of your OLED panel
- Optimize overall image quality and contrast ratio
How Pixel Refresh Works on LG OLED TVs
LG’s OLED TVs, including the B, C, and GX series, come equipped with a built-in pixel refresh feature. When enabled, the TV will:
* Analyze the on-screen content and identify areas prone to image retention
* Subtly shift the affected pixels to a nearby color or intensity, ensuring they’re not stuck in the same state
* Gradually return the pixels to their original state, all while maintaining the overall image quality
How Often Should You Perform Pixel Refresh on Your LG OLED TV?
Now that we’ve explored the importance of pixel refresh, the question remains: how frequently should you perform this task on your LG OLED TV? The answer depends on several factors, including:
* **Usage patterns:** If you primarily use your TV for gaming, video streaming, or watching TV shows with static graphics, you may need to perform pixel refresh more frequently (every 1-2 weeks).

* **TV settings:** If you have your TV set to high brightness or contrast, you may need to perform pixel refresh more frequently (every 1-2 weeks) to mitigate the risk of image retention.
* **Screen timeout and power-saving features:** If you have enabled proper screen timeouts and power-saving features, you may be able to get away with refreshing pixels less frequently (every 4-6 weeks).
As a general guideline, it’s recommended to perform pixel refresh on your LG OLED TV:
* **Every 2-4 weeks** if you use your TV for general purposes, such as watching TV shows or streaming movies.
* **Every 1-2 weeks** if you use your TV for gaming, video streaming, or watching content with static graphics.
Additional Tips for Maintaining Your OLED TV’s Health
In addition to regular pixel refresh, follow these best practices to ensure your LG OLED TV remains in top condition:
* **Adjust your TV settings:** Lower the brightness and contrast to reduce the risk of image retention.
