Asus has revealed plans for a 27-inch 1440p gaming monitor featuring LG Display’s 4th Gen Tandem RGB OLED panel, boasting a 540Hz refresh rate and 400 nits full-panel brightness. It’s expected to debut at Gamescom 2025 or CES 2026.
60% brighter than the 250 nits of Gen 3 WOLED panels
At Computex 2025, Asus showcased its latest gaming monitors, including the ROG Strix OLED XG34WCDMTG and ROG Swift OLED PG32UCDMR, both with TrueBlack Glossy coatings. Now, TFTCentral reports Asus is developing a 27-inch 1440p monitor with a groundbreaking 540Hz refresh rate, leveraging LG Display’s 4th Gen Tandem RGB OLED panel. This panel delivers 400 nits full-panel brightness—60% brighter than the 250 nits of Gen 3 WOLED panels—and a peak of 4,000 nits at 3% APL, ideal for HDR gaming.
The monitor extends Asus’ TrueBlack Glossy coating, which eliminates haze common in QD-OLED and WOLED panels, enhancing clarity and vibrancy.
It likely targets esports enthusiasts, offering motion clarity surpassing TN LCDs like Asus’ 610Hz XG248QSG. Expected features include G-SYNC, FreeSync Premium Pro, and DisplayHDR True Black 500, with connectivity like DisplayPort 1.4 and HDMI 2.1.
While pricing and the exact model name remain undisclosed, TFTCentral suggests the monitor could be unveiled sometime in late Q4 2025. Posts on X highlight excitement for the Tandem RGB panel’s brightness boost. Will this monitor redefine competitive gaming with its speed and visuals? More details are expected soon.
