AOC introduces new entry-level E4 monitors

João Silva July 16, 2025 Monitors

AOC is making a significant push into the business and professional space with the announcement of its new Essential E4 series, a lineup of ten new monitors designed for the modern workplace. Ranging from standard 24-inch displays all the way to 34-inch curved ultrawides, the series is notable for its impressive feature set, strong sustainability credentials, and a 5-year warranty on all models.

The sheer breadth of the E4 series means there's a model for nearly any professional use case. The core business models, like the 24E4U, 27E4U, and 27-inch Q27E4U, offer crisp IPS panels with resolutions from Full HD to QHD and a 120 Hz refresh rate, a significant step up from the typical 60 Hz office standard. This higher refresh rate promises smoother scrolling and reduced eye strain during long workdays. Moreover, there's also the X24E4U, featuring a WUXGA resolution.

For users demanding single-cable docking solutions, AOC has a range of USB-C enhanced models. These displays, identified by a ‘CV' in their model name, act as complete workstation hubs. They provide up to 90W of Power Delivery to charge a connected laptop, a built-in 4-port USB-A hub for peripherals, and even an RJ-45 port for a stable, wired network connection passed through the same USB-C cable. Select models also include a DisplayPort-out, allowing for easy daisy-chaining of a second monitor without a mess of cables running back to the PC. Notably, there's also a 4K model, the U27E4CV, featuring a 10-bit panel, 60 Hz refresh rate, and 400 nits of brightness.

At the top of the range are the feature-packed 34-inch ultrawide models, the CU34E4CV and CU34E4CW. These curved VA panels offer a WQHD (3440×1440) resolution and are packed with productivity features, including a built-in KVM switch to seamlessly control two different computers with a single set of peripherals. For those in constant video calls, the CU34E4CW model even integrates a 5MP webcam with Windows Hello support for secure, password-free login. Both monitors use 10-bit panels with 350 nits of brightness and a 120 Hz refresh rate.

AOC is also emphasising ergonomics and sustainability. All models feature highly adjustable stands, a 5-year warranty, and are TCO Certified generation 10. The first models of the AOC E4 series are rolling out this month. The 24E4U, 27E4U, and Q27E4U are available now for £119.00, £139.00, and £169.00, respectively. They will be followed by the USB-C variants in August and September, with the remaining models arriving in the autumn.
