AOC updates monitor lineup with first 4K dual-mode display and more
AOC is expanding its gaming monitor lineup with four new models. The most interesting is the AOC Gaming U27G4R, a 27-inch display featuring pioneering Dual-Frame (dual-mode) technology. This first-of-its-kind monitor allows gamers to quickly switch between a 4K resolution at 160Hz and FullHD resolution at 320Hz refresh rate, aiming to remove the need to compromise between visual quality and competitive performance.
Built on a Fast IPS panel, the U27G4R provides strong response times, including up to 1ms GtG in both resolution modes and impressive low MPRT figures when Motion Blur Reduction is enabled. Visual performance includes DisplayHDR 400 certification and wide colour coverage, hitting around 125% of sRGB and 96% of DCI-P3 gamuts. HDR mode can reach a 1,000 cd/m² peak, while SDR luminance is rated at 250 cd/m². The display supports Adaptive-Sync for tear-free gaming across AMD and Nvidia GPUs, and is compatible with current consoles at UHD at 120Hz with VRR.




The U27G4R follows the aesthetic of the G4 series, featuring a space-saving base finished in matte black with subtle red accents. Its ergonomic stand offers versatile adjustment, including 130mm height adjustment, tilt, swivel, and pivot functions. Port selection includes two HDMI 2.1 connectors, one DisplayPort 1.4 port, and a USB 3.1 hub with four downstream ports for connecting peripherals. Moreover, it also packs a range of gaming features like a crosshair overlay, Low Input Lag mode, and controls for shadow/colour settings, all accessible via the OSD menu or AOC's G-Menu software. Utility features like PiP/PbP modes and comfort tech like anti-blue light are also included.
Besides the U27G4R, AGON by AOC is expanding its G4 series portfolio with three additional models arriving in May 2025. The AOC Gaming CU34G4 is a 34-inch ultrawide curved gaming monitor, offering a 3440×1440 resolution and a 180Hz refresh rate on a Fast VA panel with a 1500R curvature, positioned as a more accessible alternative to their higher refresh rate ultrawide displays. Joining it are updates to their mainstream line: the 24-inch 24G4HA and 27-inch 27G4HA. These models boast an increased 200Hz refresh rate (up from 180Hz on predecessors), and retain features like ergonomic stands and built-in speakers. Both also carry Nvidia G-SYNC Compatible certification.
All four new AGON by AOC G4 series monitors are scheduled for release in May. The AOC Gaming U27G4R will cost £299, while the CU34G4 will cost £289. Lastly, the 24G4HA will cost £134, and the 27G4HA will cost £154.
