AGON by AOC is expanding its G4 gaming series with the new CU34G4CA and CU34G4ZCA. Both 34-inch ultrawide monitors feature a 3440 × 1440 Fast VA panel with a 1500R curve, USB-C charging up to 90W, and a built-in KVM switch. The new displays reach retailers in August and are aimed at users who want a single monitor for gaming and daily work.
Each monitor features a 21:9 WQHD panel with DisplayHDR 400 certification, up to 450 nits of peak brightness, and a 2,500:1 contrast ratio. The ultrawide format gives more room for multiple applications on screen, while the curved panel fills more of the player’s view in racing games, flight simulators, open-world adventures, and strategy titles.
The CU34G4CA runs at 180Hz with a 0.5ms MPRT response time. The CU34G4ZCA increases the native refresh rate to 240Hz and supports overclocking up to 250Hz. Its MPRT response time drops to 0.3ms. Both monitors are rated for up to 1ms GtG response time, helping reduce motion blur during fast-moving scenes.
USB-C supports video, data transfer, and laptop charging through a single cable with up to 90W Power Delivery. The built-in KVM switch lets one keyboard and mouse control two connected computers, making it easy to move between a desktop PC and a notebook without reconnecting peripherals.


A built-in USB hub provides two USB 3.2 Gen 1 ports for accessories such as storage drives, keyboards, mice, and headsets. AOC ships both displays with USB-C, HDMI, and DisplayPort cables, allowing buyers to connect the monitor straight out of the box.
Adaptive Sync reduces screen tearing during gameplay, while AOC’s G-Menu software allows picture settings, gaming presets, and display options to be changed directly from Windows instead of the monitor’s on-screen menu.
The stand supports 130mm of height adjustment, along with swivel and tilt adjustment. Both displays support 100 × 100mm VESA mounts for monitor arms. Flicker-Free technology and Low Blue Mode are available for users who spend long hours in front of the screen.

The connection layout is almost the same on both models. The CU34G4CA comes with two HDMI 2.0 ports, one DisplayPort 1.4 connector, USB-C with 90W Power Delivery, two USB 3.2 Gen 1 ports, and a 3.5mm audio jack. The CU34G4ZCA replaces the HDMI 2.0 ports with HDMI 2.1 while keeping the remaining connections unchanged.
The AOC GAMING CU34G4CA reaches stores in August with a suggested retail price of £289.99. The CU34G4ZCA arrives during the same month for £329.99, offering a higher refresh rate while keeping the rest of the hardware largely the same.
