AGON by AOC has just dropped a trio of new QHD displays designed to bring esports-level performance to a wider audience without breaking the bank. Leading the charge is the incredibly fast AOC GAMING Q25G4SR, offering a stunning 300 Hz refresh rate in a compact 24.5-inch form factor. Not to be outdone, the 27-inch AOC GAMING Q27G4ZR and the budget-friendly Q27G42ZE both deliver a solid 240 Hz performance, with an impressive overclocking capability up to 260 Hz.
AOC GAMING Q25G4SR: Compact Speed Demon

For those who crave both speed and clarity in a smaller package, the Q25G4SR is a real standout. This 24.5-inch monitor boasts a crisp QHD (2560×1440) resolution, resulting in a superb pixel density of 119.89 PPI. It’s pitched as the spiritual successor to the popular AOC GAMING Q24G2A, offering that sought-after combination of high resolution and a more desk-friendly size. Equipped with a Fast IPS panel, this monitor hits an astonishing 300 Hz refresh rate, ensuring buttery-smooth gameplay. Response times are equally impressive, with up to 1 ms GtG and a razor-sharp 0.3 ms MPRT when using Motion Blur Reduction (MBR). Beyond raw speed, the Q25G4SR doesn’t skimp on features:
- VESA Certified DisplayHDR 400: Delivers vibrant highlights and rich contrast to bring your games to life.
- Fully Ergonomic Stand: Offers 130 mm height adjustment, tilt, swivel, and pivot functionality for optimal comfort.
- Comprehensive Connectivity: Features two HDMI 2.1 ports and one DisplayPort 1.4, ready for the latest graphics cards and next-gen consoles without bandwidth limitations.

If a larger screen is more your style, AGON by AOC also offers two 27-inch QHD options. The Q27G4ZR is positioned as the top choice in the 27-inch category. It comes with a 240 Hz refresh rate that can be overclocked to a blistering 260 Hz.
- Fast IPS Panel: Offers rapid response times of up to 1 ms GtG and 0.3 ms MPRT with Motion Blur Reduction.

For gamers keeping an eye on their wallets, the Q27G42ZE provides the same core performance as the Q27G4ZR, boasting a 240 Hz refresh rate that’s also overclockable to 260 Hz. It utilises an almost identical Fast IPS panel. To achieve its budget-friendly price point, some features have been streamlined:
- Tilt-Only Stand: A simpler stand compared to its fully ergonomic siblings.
- Simplified Connectivity: Features one HDMI 2.0 and one DisplayPort 1.4.
- Brightness: Offers 300 cd/m² brightness.
