Product information

Description

The AOC U27B3M is a 27-inch UHD monitor with a VA panel that delivers deep contrast and rich color reproduction. It supports HDR10 for improved dynamic range and AdaptiveSync for smoother motion at a 60 Hz refresh rate. Eye comfort features such as low blue light and flicker-free technology help reduce visual fatigue during extended use, while the standard stand provides stable placement for everyday workspace needs.

Advantages

The VA panel provides strong contrast and vivid colors suitable for multimedia and office work. HDR10 enhances detail in bright and dark areas, and AdaptiveSync reduces screen tearing and stutter. Low blue light and flicker-free technologies are included to support prolonged viewing sessions. The monitor’s 27-inch UHD resolution offers a large, sharp workspace for multitasking.

Key specifications

  • Screen size: 27 inches (UHD)
  • Panel type: VA
  • Resolution: UHD (3840 × 2160)
  • Refresh rate: 60 Hz
  • AdaptiveSync: supported
  • HDR: HDR10
  • Eye comfort: low blue light, flicker-free
  • Stand: basic/normal

How to use

Connect the monitor to your PC or laptop using a compatible video cable (DisplayPort or HDMI) that supports UHD at 60 Hz. Adjust display settings from your operating system or the monitor’s on-screen menu to enable AdaptiveSync and HDR10 if supported by your graphics card and source. Use the low blue light mode and flicker-free setting for extended sessions to reduce eye strain. Place the monitor on a stable surface and adjust viewing distance and angle to suit ergonomic needs.

Recommendations

For best results, use a graphics card and cable that support 4K at 60 Hz and enable HDR10 in both the monitor menu and your source device. Position the monitor at eye level and take regular breaks to minimize eye fatigue during long use.

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 results in a more realistic, immersive and smoother gaming experience — you’ll feel like you’re stepping into the game, frame by frame.

Low Blue Light

AOC Lowblue Light protects you from harmful blue light which, during long sessions, can cause eye strain, headaches and sleep disturbances. The Lowblue Light feature reduces harmful wavelengths without sacrificing color fidelity, letting you enjoy extended use without worrying about eye damage.

Flicker Free

AOC Flicker-Free Technology uses a DC (Direct Current) backlight panel to reduce flicker. With eye strain and fatigue greatly minimized, you can enjoy long, intense gaming sessions in greater comfort.

Frameless design

Besides looking modern and attractive, frameless designs enable seamless multi-monitor setups. Your cursor and windows won’t get lost in the dark bezels when several displays are placed side by side.

UHD (4K) Resolution

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

Adaptive sync

Adaptive Sync aligns your monitor’s vertical refresh rate with the frame rate delivered by your GPU, making gameplay and casual gaming smoother by eliminating stutter, tearing and judder. This feature also improves playback of videos and other visual media for smoother entertainment.
