LG Display Enters 27-inch 4K OLED Race with 240Hz RGB-Stripe Panel

Key Highlights

  • LG Display unveils its first-ever 27-inch 4K OLED monitor panel
  • Features a true RGB-stripe sub-pixel layout for sharper text
  • Supports 240Hz refresh rate and 480Hz dual-mode at 1080p
  • Designed for gaming, productivity, and high-end monitors
  • Expected to grab attention at CES 2026

LG Display has announced a new OLED panel that could redefine high-end monitors in 2026. The company revealed a 27-inch 4K OLED panel with a 240Hz refresh rate, marking its first OLED panel in this size and resolution category

This move places LG Display directly against Samsung Display’s QD-OLED offerings. It also signals a major shift in how OLED monitor panels are designed.

A Big Shift to RGB-Stripe OLED

The biggest upgrade is the move to a true RGB-stripe sub-pixel layout. Unlike older WOLED panels, this design removes the white sub-pixel entirely. Each pixel now uses only red, green, and blue sub-pixels arranged in a straight line.

This structure improves text clarity and reduces colour fringing. It also aligns better with modern operating systems like Windows. As a result, the panel should deliver cleaner fonts and sharper UI elements, even at close viewing distances.

LG Display lists the pixel density at around 160 PPI, which puts it among the sharpest OLED monitor panels available today.

High Refresh Rates with Dual-Mode Support

The panel supports a native 240Hz refresh rate at 4K resolution. LG Display also adds a dual-mode feature that switches the panel to 1080p at 480Hz.

This Dynamic Frequency and Resolution technology allows users to prioritise resolution or speed. Competitive gamers can opt for higher frame rates, while creators and professionals can stick with full 4K clarity.

LG Display says this is the first OLED panel to combine an RGB-stripe layout with such high refresh rates.

Where This Panel Fits in LG’s OLED Lineup

LG Display has not clearly classified the panel under its existing Tandem OLED branding. The company previously used Tandem WOLED for large displays and Tandem OLED for smaller screens like laptops.

The lack of clarity raises questions about brightness levels, lifespan, and HDR performance. Without the white sub-pixel, peak brightness may be lower than recent WOLED panels. However, colour brightness and HDR colour volume could improve due to pure RGB light output.More technical details are expected at CES in January.

What Comes Next

This announcement focuses on the panel, not a finished monitor. It remains unclear which brands will adopt it. Monitor makers like Asus and LG Electronics often rely on LG Display panels, making CES a key event to watch.

LG Display has also teased a 39-inch 5K2K ultrawide OLED panel, hinting at a strong OLED push in 2026.
