AOC has just launched two new gaming monitors with a focus on offering high quality “at attainable price points”. The two displays in question are the AOC Gaming CU34G4Z and 25G4SXU, which are QHD ultrawide and 1080p displays, respectively. With the 25G4SXU, you’ll be able to break the 300Hz barrier for less than £200 (around $255 USD).

The full HD esports monitor comes with a fast 300Hz panel, which can be overclocked to 310Hz, while the ultrawide monitor boasts a fast 240Hz refresh rate of its own. Whether you’re looking for an esports-focused display for FPS or something a little larger that offers a better productivity/gaming balance, AOC has you covered with this launch.

Press release in full

Amsterdam, 9 April 2025 – AGON by AOC – world’s leading gaming monitor brand – elevates performance-to-price expectations with two new G4 displays: the AOC GAMING CU34G4Z, a curved 34-inch (86.4 cm) ultrawide monitor with an impressive 240 Hz refresh rate, and the AOC GAMING 25G4SXU, a 24.5-inch (62.2 cm) esports-focused screen featuring a lightning-fast 300 Hz panel (overclockable to 310 Hz). These new models deliver the high refresh rate advantage that competitive gamers demand, without the premium price tag typically associated with such performance.

Ultrawide meets ultra-fast: beyond the racing line

The CU34G4Z elevates gaming across multiple genres with its 34-inch curved (1500R) VA panel, UWQHD resolution (3440×1440), and exhilarating 240 Hz refresh rate. The expansive 21:9 aspect ratio provides significant advantages in various gaming scenarios — from the increased peripheral vision benefits in racing and flight simulators to the strategic overview in RTS and MOBA titles, and the cinematic immersion in open-world adventures. The high refresh rate ensures smooth motion in all fast-paced content, while response times of up to 1 ms GtG and 0.3 ms MPRT using Motion Blur Reduction mode maintain exceptional clarity during rapid on-screen movement.

The DisplayHDR 400 certification enhances visual impact with vibrant colours and improved contrast in supported content. 1x DisplayPort 1.4 and 2x HDMI 2.1 connectivity ensures compatibility with the latest graphics cards and gaming consoles to ensure the bandwidth for high resolution, high colour depth (1.07 billion colours) and high refresh rates. The ergonomic stand offers height, tilt, and swivel adjustments for optimal viewing comfort during extended gaming sessions.

Competitive edge at 300 Hz and above: precision redefined

The 25G4SXU delivers tournament-grade performance to the AOC GAMING range with its 24.5-inch Fast IPS panel running at a blistering 300 Hz, with the overclocking option via OSD to 310 Hz at Full HD resolution. Featuring response times up to 1 ms GtG and 0.3 ms MPRT, this display provides the split-second visual clarity that can make the difference between victory and defeat in competitive play.

The monitor’s esports-inspired design includes a 130 mm height-adjustable stand with a low-profile, asymmetric base that maximises desk space and accommodates the angled keyboard setups preferred by many professional players. The stand is also capable of tilt and swivel adjustments as well as portrait (pivot) mode. Adaptive-Sync technology and NVIDIA G-SYNC compatibility ensures smooth, tear-free visuals, while the dedicated Low Input Lag mode delivers the immediate feedback essential for twitch reflexes in high-stakes competition.

“Our newest G4 models reflect our understanding that different gaming genres demand specialised performance,” says César Acosta, Gaming Product Manager at AGON by AOC. “While we continue to push boundaries with QD-OLED technology in our AGON PRO lineup, we’re bringing targeted high-performance features to our AOC GAMING range. The CU34G4Z delivers exactly what simulation enthusiasts have been asking for, while the 25G4SXU provides competitive players with the frame rate advantage they need — all at price points that make sense for dedicated gamers.”

Complete gaming solutions

Both monitors come equipped with USB 3.2 Gen 1 hubs (2-port for the CU34G4Z, 4-port for the 25G4SXU) for convenient peripheral connectivity and include support for AOC’s G-Menu software for easy access to gaming presets and display settings. HDR10 support provides enhanced visuals in compatible content, while Flicker-Free technology and Low Blue modes reduce eye strain during extended gaming sessions.

The CU34G4Z excels in multiple gaming scenarios: racing simulators benefit from the expanded peripheral vision and smooth motion at speed; strategy and MOBA games gain valuable screen real estate for battlefield awareness; content creators appreciate the workflow-friendly aspect ratio; and single-player adventures deliver a more cinematic, immersive experience.

Meanwhile, the 25G4SXU is the weapon of choice for competitive gamers in fast-paced shooters like Counter-Strike 2, Valorant, and Overwatch, where every frame can be the difference between landing the perfect shot and missing entirely.

Pricing and availability

The AOC GAMING CU34G4Z and 25G4SXU will be available from April 2025 at MSRPs of £369.00 and £199.00, respectively.
