ASUS ROG Leads Gaming Monitor Innovation with LG Display’s 4th-Generation White OLED
ASUS’s gaming brand, ROG, recently released its 27-inch gaming monitor, the ROG Swift OLED PG27AQWP-W, featuring LG Display’s latest 4th-generation white OLED panel. LG Display is extending its proven TV technology to the monitor market, enhancing brightness and durability to address OLED’s weaknesses. ASUS, a top-five global gaming monitor manufacturer, has adopted this new OLED panel for its ROG series, marking a significant step toward popularizing OLED technology in the premium gaming monitor market.
The ROG Swift OLED PG27AQWP-W features a 26.5-inch QHD resolution, 4th-generation white OLED panel, and supports dual modes: 540Hz in QHD and 720Hz in HD. It boasts a fast response time of 0.02ms, and the application of LG Display’s 4th-generation white OLED technology delivers high luminance efficiency and a lifespan that’s approximately 60% longer than previous models. Color expression has been improved by 25%, and maximum brightness has been increased by 15% compared to the previous model.

The structure of the 4th generation white OLED is a 4-layer configuration including 2 blue light-emitting layers and red and green layers. On the other hand, the 3rd generation white OLED was a 3-layer structure with 2 blue light-emitting layers and red, green, and yellow elements arranged in one layer, and a Micro Lens Array (MLA) was applied. The peak brightness (based on 1.5% APL) of the ‘ROG Strix OLED XG27AQDMG’ using the 3rd generation OLED was around 1,300 nits, but this new model with the 4th generation OLED applied has improved to 1,500 nits, realizing much clearer HDR picture quality.

LG Display’s 4th-generation OLED was first applied to LG Electronics’ “UltraGear 27GX700A” gaming monitor, in addition to ASUS. This model demonstrated the performance of the new OLED technology, achieving a full white brightness of 335 nits and a peak brightness of 1,500 nits. Starting with this ASUS ROG model, LG Display plans to expand the application of the 4th-generation white OLED to various IT monitors. Building on its expertise in OLED TVs, LG Display aims to deliver a new level of picture quality competitiveness in both gaming and creative applications.
“LG Display’s 4th-generation OLED is expected to accelerate the adoption of OLED in both the gaming and IT display markets by applying proven TV technology to monitors,” said Changwook Han, Executive Vice President of UBI Research. “In particular, the improved lifespan and high brightness achieved through the 4th-generation white OLED structure will be a significant turning point in the competitive landscape of the high-end gaming monitor market.”
