Product information

Description

The AOC U27B3A is a 27-inch 4K Ultra HD (3840 x 2160) LCD monitor designed for productivity. It uses an IPS panel to provide wide 178° viewing angles, a 60 Hz refresh rate and a 4 ms response time. The display supports HDR10 and Adaptive Sync for smoother, clearer visuals, includes a low blue light mode to reduce eye strain and has built-in 2 W speakers. The monitor features a slim three-sided frameless design, VESA mounting support and a flat black housing.

Advantages

This AOC monitor delivers high-resolution 4K clarity on a 27-inch screen with consistent colour and viewing angles thanks to its IPS panel. HDR10 support enhances contrast and colour depth, while Adaptive Sync minimises tearing during motion. A low blue light setting helps reduce visual fatigue during extended use, and integrated speakers provide basic audio without external devices. VESA compatibility offers flexible mounting options for different workstation setups.

Suitable for

Office productivity and multitasking with high-resolution workspace
Viewing and editing photos or detailed documents
Watching UHD video content with HDR10 support
General home or office use where a compact 27" 4K display is required

Reasons to buy

Live the game at its best with HDR10

HDR10 enhances picture quality further by improving synchronization between your GPU or console and the monitor. This produces a more realistic, immersive and smooth gaming experience — you’ll feel like you’re stepping into the game, frame by frame.

Adaptive sync

Adaptive Sync aligns the monitor’s vertical refresh rate with the frame rate delivered by your GPU, making gameplay and casual gaming even more fluid by eliminating stuttering, tearing and judder. This feature is also useful for videos and other visual media, providing smoother entertainment.

Low Blue Light

AOC Lowblue Light protects you from harmful blue light which, during long sessions, can cause eye strain, headaches and sleep disorders. The Lowblue Light feature reduces harmful wavelengths without sacrificing color composition, letting you use the display with less worry about eye damage.

Speakers

Built-in speakers make it easy to stay connected with family, friends and colleagues. For movies, music, games and more, you’ll get quality audio without the hassle of connecting external speakers.

Frameless design

Besides looking modern and attractive, a frameless design enables seamless multi-monitor setups. Your cursor and windows won’t be lost in the dark abyss of bezels when multiple displays are placed side by side.

UHD (4K) Resolution

4K Ultra High-Definition (3840 x 2160) resolution delivers ultra-crisp picture quality and allows you to see more on the screen at once. This provides more screen "real estate" and reveals greater detail for sharper, more brilliant images. Whether working on a photo, a design, or using the display for productivity, you’ll appreciate the true, crisp image that only a UHD display can provide.
