AOC CU34E4CW Ultrawide 120Hz Professional Monitor Review

AOC is by far one of the biggest names in monitors, with a range that spans budget office numbers to flagship OLED gaming monitors, and everything in between. Their new monitor, the CU34E4CW, is positioned as a comprehensive hub for the modern hybrid workspace, blending business-focused productivity features, making it ideal for PC enthusiasts and gamers seeking a versatile ultrawide experience that won’t break the bank. Largely, it is built as a productivity monitor, making it well-suited for the work-from-home environment, but that doesn’t mean you can’t fire up some games at the end of a long workday.

As a 34-inch curved display, it is designed to enhance multitasking and connectivity. It features an UltraWide Quad HD resolution and a 120Hz refresh rate, promising crisp visuals and fluid motion for both work and gaming sessions. Given its built-in docking capabilities and built-in essential peripherals, the expectation is a highly streamlined and clutter-free setup that makes switching between professional and leisure use surprisingly effortless.

Central to its appeal is the single-cable setup offered by the dual USB-C inputs, which not only transfer high-resolution video but also provide up to 90W of Power Delivery to charge a connected laptop. For users managing multiple systems, the Smart KVM switch is invaluable, allowing a single keyboard, mouse, and monitor to control two different PCs seamlessly. Furthermore, the inclusion of a 5MP webcam with Windows Hello facial recognition offers convenient, secure log-in and high-quality video conferencing. The monitor also prioritises user comfort with an ergonomic stand with plenty of adjustments.
