LG Display Unveils World’s First 240Hz 4K RGB OLED Monitor Panel

We have great news for the gamers because LG Display has made a big announcement in terms of monitor technology by introducing the world’s first 27-inch 4K OLED panel with a 240 Hz refresh rate and an RGB stripe subpixel structure. Developed with the high-end gaming and professional monitor markets in mind, it is set to make its debut at CES 2026.

The red, green, and blue subpixels are aligned in a straight line by the RGB stripe structure — Most people agree that this layout is good for image clarity because it reduces artifacts like color bleeding and fringing, especially when looked at closely. This makes RGB stripe panels perfect for desktop monitors, which need to show text clearly and fine details.

Up until now, though, OLED panels with this structure could only refresh at around 60 Hz, which meant they weren’t very good for fast-moving content or games; LG Display’s new panel is the first one to pair the RGB stripe configuration with a 240 Hz refresh rate, overcoming a long-standing technical barrier .

Dynamic Frequency and Resolution (DFR) technology from LG Display are another important components of the new panel, allowing the users to switch between different operating modes depending on their priorities. One mode delivers Ultra High Definition (UHD) resolution at 240 Hz, focusing on visual detail and image quality, while the other prioritizes speed, offering Full HD (FHD) resolution at up to 480 Hz for applications where ultra-high refresh rates are more important than resolution, such as competitive gaming .

The panel promises crisp images and precise color reproduction with a pixel density of 160 PPI. LG Display is strongly reinforcing how its high resolution, RGB stripe layout, and quick refresh rate enhance text readability and overall visual consistency, marketing it as the perfect panel for professional tasks that require accurate font rendering and intricate graphics, as well as for use with operating systems like Windows.

To make all this tech this work, LG Display came up with new ways to make screens; One of these was to improve the aperture ratio, which makes more of each pixel emit light. The panel is different from many other OLED monitors because it has RGWB structures that include a white subpixel or alternative pixel arrangements.

The manufacturer plans to initially roll out this tech in premium gaming and professional monitors, strengthening its efforts to expand its presence in the higher-end OLED monitor segment and consolidate its leadership through uniquely designed display technologies .
