AOC Launches U27G4XM Mini LED Monitor With Up To 320 Hz Refresh Rate and HDR 1000 Support; Debuts a Budget 25G4KUR 420 Hz Monitor For Gamers as Well

Popular monitor maker, AOC, has launched two new high-end gaming monitors in its AOC Gaming lineup, introducing excellent options for competitive gamers as well as those who want high-fidelity visuals. AOC usually releases IPS and VA-based monitors most of the time, but recently also debuted its first AOC Gaming QD-OLED monitors as well. This time, it has launched a new model called U27G4XM, based on a Mini LED panel, featuring dual display modes.

Unlike conventional LED monitors like IPS and VA, the mini LED displays use thousands of smaller backlight zones, allowing for far more precise local dimming, higher contrast, and, of course, better HDR performance. The AOC U27G4XM brings 1152 such zones and also DisplayHDR 1000 certification, offering a staggering 1200 Nits of Peak brightness for excellent HDR performance. So, it's not just for gaming, but for watching high-fidelity HDR content like movies as well as making an outstanding monitor for enthusiast gamers, delivering up to 320 Hz of refresh rate.

Since it boasts a dual mode configuration, users can switch between 160Hz@4K and 320Hz@FHD modes to select their preferred mode for gaming. The color reproduction is also going to be very vibrant due to a wide color gamut, including color spaces like 151.8% sRGB and 98% DCI-P3. For those who are on a tighter budget, AOC has released another fantastic option called AOC Gaming 25G4KUR, which offers an incredible 420Hz@1080p mode for competitive gaming.

These monitors represent the perfect example of how AOC GAMING serves different gaming needs,

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.

This monitor utilizes a Fast IPS panel with just 1 ms GtG response time, and also brings G-Sync compatibility for tear-free gaming. The monitor boasts a 24.5" screen size and offers decent HDR400 support for improved visual quality. Surely, it can't compete with the Mini LED model, but at £209.99, it's a fantastic budget eSports display for serious gamers. On the other hand, the U27G4XM will be available for £399.99, starting January 2026.
