Two great options from AGON by AOC: a HDR1000 MiniLED Dual Mode powerhouse and a dedicated 420 Hz compact esports monitor. The U27G4XM delivers ultimate HDR visuals with Dual Frame versatility, whilst the 25G4KUR focuses on pure competitive speed.
AGON by AOC – the world’s leading gaming monitor brand by volume – announces two distinct AOC GAMING monitors targeting different gaming experiences:
- The 27-inch (68.6 cm) AOC GAMING U27G4XM brings premium MiniLED technology with 1152 local dimming zones and DisplayHDR 1000 certification to mainstream pricing, featuring Dual Frame Mode for ultimate versatility between immersive UHD and competitive FHD gaming.
- The AOC GAMING 25G4KUR delivers a 420 Hz overclocked refresh rate (400 Hz native) performance in the competitive 24.5-inch (62.2 cm) format, providing dedicated esports players with the speed and precision needed for professional-level gaming at an accessible price point.
MiniLED HDR excellence enters mainstream gaming with 420Hz competitive performance
The U27G4XM represents the evolution of premium display technology, surpassing even the acclaimed, similar spec-ed Q27G3XMN with higher 4K resolution, modern Fast IPS panel technology, and enhanced G4 series design. This 27-inch HDR powerhouse combines 1152 local dimming zones with a DisplayHDR 1000 certification and 1200 cd/m² peak brightness to create exceptional HDR performance that brings games, movies, and content to life with unprecedented detail and contrast.
MiniLED technology provides gamers with superior local dimming control, enabling near-OLED black levels alongside exceptional brightness that OLED cannot yet match – crucial for spotting enemies in dark areas while maintaining vibrant explosions and effects. With 1200 cd/m² peak brightness, the U27G4XM delivers an impressive HDR experience with stunning highlights and deep blacks, all without the burn-in concerns associated with OLED technology, making it perfect for extended gaming sessions and varied content. The Dual Frame Mode technology offers the best of both worlds: gamers can instantly switch between stunning 4K at 160 Hz for immersive single-player adventures and ultra-fast FHD at 320 Hz for competitive multiplayer, eliminating the need for multiple monitors.
The monitor truly “has everything” – exceptional colour accuracy with 151.8% sRGB and 98.0% DCI-P3 coverage from its Fast IPS panel, Dual Frame flexibility for choosing between pin-sharp 4K at 160 Hz or super-fast FHD at 320 Hz, and the MiniLED backlighting that delivers true HDR1000 performance. Whether exploring vast open worlds in 4K detail or competing in fast-paced multiplayers at 320 Hz, the U27G4XM adapts to the gaming needs without compromise.
420 Hz esports domination made accessible
The 25G4KUR targets the core of competitive gaming with 420 Hz overclocked performance in the preferred 24.5-inch esports format. This compact size eliminates head movement and allows gamers to “lock-in” and focus during intense gaming sessions while providing the 86.38 pixels per inch clarity that competitive players demand. The Full HD resolution ensures that virtually any modern graphics card can achieve consistent 420 Hz framerates, making ultra-high refresh gaming accessible to a broader audience.
Built around a Fast IPS panel, the 25G4KUR delivers response times of up to 1 ms GtG and 0.3 ms MPRT with DisplayHDR 400 and comprehensive colour coverage including 121.0% sRGB. NVIDIA G-SYNC Compatible support and Adaptive-Sync technology provide tear-free gaming across variable refresh rates, while Low Input Lag mode ensures instantaneous response for competitive advantage.
“These monitors represent the perfect example of how AOC GAMING serves different gaming needs,” says César Acosta, Gaming Product Manager at AGON by AOC. “The U27G4XM takes MiniLED HDR1000 technology to mainstream pricing with Dual Frame flexibility – perfect for console gamers and single-player enthusiasts who also want competitive performance. The 25G4KUR is pure esports dedication – 420 Hz in the ideal 24.5-inch format at a price that makes sense for competitive players and esports training facilities.”
Premium visual technology meets console gaming
The U27G4XM excels as a console gaming display, supporting 4K @ 120 Hz for PlayStation 5 and Xbox Series X while delivering the HDR performance that brings game worlds to life. The 1152 local dimming zones provide precise contrast control that reveals details in both bright highlights and deep shadows, crucial for both competitive advantage and immersive storytelling.
Wide Color Gamut technology with 151.8% sRGB and 98.0% DCI-P3 coverage ensures accurate colour reproduction for content creation, while the Dual Frame Mode allows instant switching to high-refresh competitive gaming without needing a second monitor. HDMI 2.1 and DisplayPort 1.4 connectivity support the latest graphics cards and consoles.
Esports-focused design philosophy
The 25G4KUR embodies competitive gaming priorities with its 24.5-inch form factor – the size preferred by professional esports players for optimal peripheral vision and reduced eye movement. The 420 Hz refresh rate provides the ultimate competitive edge for MOBA, FPS, and tactical shooter games where split-second reactions determine victory.
Console compatibility includes FHD @ 120 Hz support, while comprehensive gaming features include Shadow Control for enhanced visibility, Game Color optimisation, and dedicated gaming modes for different competitive scenarios. The ergonomic stand provides 130 mm height adjustment with full tilt, swivel, and pivot functionality for optimal ergonomic positioning.
