AOC Gaming CU34G4ZCA Monitor Launches With 250 Hz Overclocking

AOC is launching two new curved ultrawide monitors that bridge the gap between high-speed gaming and daily productivity. The GAMING CU34G4CA and GAMING CU34G4ZCA models arrive in August 2026 with 90W USB-C power delivery, allowing a single cable to drive both video and a connected laptop. This setup saves desk space and simplifies connections for users who juggle work and play on the same screen.

Dual 34-inch ultrawide monitors offer 90W USB-C connectivity and 1500R curvature for gaming and work

Both monitors feature a 34-inch Fast VA panel with a 21:9 aspect ratio and a 1500R curvature designed for immersive gameplay. The base resolution is 3440x1440p, which provides the extra horizontal space needed for racing sims and sprawling open-world titles. AOC positions these displays as primary tools for gamers who also need a capable workspace for their daily tasks.

Spec comparison

The two models split their performance focus between standard high refresh rates and overclocked speed. The CU34G4CA runs at 180 Hz with a 0.5 ms MPRT response time. The CU34G4ZCA pushes to 240 Hz out of the box and can overclock to 250 Hz with a faster 0.3 ms MPRT response. Both models carry DisplayHDR400 certification and reach 450 nits of peak brightness.

Connectivity centers on the USB-C port, which supports 90W Power Delivery and DisplayPort Alt Mode. The I/O panel also includes two HDMI 2.0 ports, one DisplayPort 1.4 interface, and a built-in KVM switch. Users can connect multiple computers and switch between them using the dual USB 3.2 Gen 1 hub ports on the monitor itself.

Pricing for the UK market starts at 289.99 GBP (around $391) for the 180 Hz CU34G4CA model. The faster 240 Hz CU34G4ZCA is priced at 329.99 GBP (around $445). Both monitors are scheduled for retail launch in August 2026. We looked at AOC Unveils AGON PRO AGP257FT Gaming in our earlier Aoc coverage.
