Blazing refresh rates meet budget-friendly pricing
AOC has introduced the 25G4K, a 24.5-inch gaming monitor aimed squarely at esports players and competitive gamers. Listed on JD.com for 1,599 yuan (about $222), the new display promises striking motion clarity thanks to an overclocked 420Hz refresh rate and a host of pro-level features usually reserved for more expensive panels.
Key specifications and display technology
Panel, resolution and refresh
The 25G4K uses a Fast IPS panel with a native 1920 x 1080 resolution. Over DisplayPort it supports an overclocked refresh rate up to 420Hz, delivering ultra-smooth motion during fast-paced gameplay. Response time is rated at 1ms GTG with a 0.3ms MPRT figure, minimizing ghosting and motion blur.
Brightness, HDR and color accuracy
AOC equipped the monitor with VESA DisplayHDR 400 certification, enabling up to 400 nits peak brightness and improved contrast for HDR content. Each unit ships factory-calibrated with a Delta E < 2 and covers 92% of the DCI-P3 gamut (CIE 1976). A six-axis color adjustment system lets users fine-tune hue and saturation per channel for precise color work or competitive tuning.
Gaming features and adaptive sync
The 25G4K integrates AOC’s MBR Sync to further reduce motion blur and supports AMD FreeSync and Adaptive-Sync to prevent tearing and stutter. Competitive-focused extras include Dark Boost for better visibility in shadowed areas, an intelligent crosshair with a sniper zoom mode, and GameMode/GameColor presets for quickly switching contrast and saturation settings by genre.
Ergonomics, connectivity and eye care
The stand offers solid adjustability: 130mm height, -5° to 23° tilt, ±30° swivel and ±90° pivot, plus VESA 100 × 100mm compatibility for wall mounts. Ports include one DisplayPort 1.4, two HDMI 2.0 inputs and a 3.5mm audio jack. AOC also uses DC dimming and hardware-level low blue light to reduce flicker and eye strain during long sessions. Weight is 4.22 kg with the stand and 2.85 kg without.
How it stacks up and who should buy it
Compared with premium alternatives — like AOC’s own 500Hz QD-OLED flagship or other high-end screens — the 25G4K delivers competitive refresh performance at a fraction of the price. It’s ideal for esports competitors, FPS and fast-twitch gamers who prioritize frame-rate and input responsiveness over ultra-high resolution. For creators or HDR enthusiasts seeking deeper color volume and OLED-level contrast, higher-end 4K HDR or QD-OLED options remain better choices.
Use cases and market relevance
The AOC 25G4K addresses a growing segment of the market: budget-conscious competitive gamers who want maximum frame-rate and low latency without breaking the bank. At roughly $222 in China, it undercuts many high-refresh alternatives while delivering feature-rich adaptive sync, factory color calibration and ergonomic flexibility. The release also highlights broader trends in gaming displays — aggressive refresh-rate overclocking and specialized esports features migrating into affordable tiers.
Price and availability
Currently listed on JD.com for 1,599 yuan (~$222), the monitor looks to be targeted at the China market first. Global availability and pricing may vary, but the 25G4K presents a compelling option for anyone seeking a 420Hz Fast IPS esports monitor at an entry-level price point.
In related news, Xiaomi recently launched its 2026 Redmi A27U Type-C monitor with 4K HDR and 90W USB-C charging, while AOC continues to push the envelope with a 500Hz QD-OLED gaming monitor featuring HDR True Black 500 certification and a 0.03ms response time.
