## Long description

The AOC E4 CU34E4CW is a 34" UltraWide Quad HD (3440 x 1440) curved monitor designed for multitasking and hybrid work. It uses a VA LED panel with a 21:9 aspect ratio, 120 Hz refresh rate and 4 ms response time to deliver smooth motion and wide viewing angles. The display includes HDR10 and Hardware Anti-Blue Light for improved image clarity and reduced eye strain. Integrated features such as a 90W PD docking station, Smart KVM, a built-in 5 MP webcam, speakers and a USB 3.2 Gen 1 hub make it suitable as an all-in-one workstation display.
Advantages
The CU34E4CW combines a large 34" UWQHD curved panel with a high 120 Hz refresh rate for fluid visuals and a high native contrast ratio typical of VA technology.

Eye-care features such as Hardware Anti-Blue Light and flicker-free technology help minimise visual fatigue during extended use.
