## Long description

The AOC U27B3AF is a 27-inch UHD (3840x2160) monitor designed for productive work. It features a three-sided frameless design, a 60Hz refresh rate and HDR10 support to deliver clear visuals.

Advantages
The three-sided frameless bezel provides an expansive viewing area suitable for multi-monitor setups. Height adjustment reduces neck and shoulder strain by allowing optimal screen positioning.

How to use
Place the monitor on a stable desk surface and connect it to your computer using a compatible video cable. Adjust the height of the stand to set the top of the screen at or slightly below eye level to maintain neutral neck posture. Enable Adaptive Sync in your graphics driver or monitor OSD to reduce tearing. If needed, activate HDR10 in the operating system and application settings for supported content. Use the built-in speaker for basic audio or connect external speakers/headphones for fuller sound.
Recommendations
For best ergonomic setup, position the monitor about an arm’s length away and ensure the center of the screen is slightly below eye level. Use a digital video connection that supports UHD at 60 Hz and enable Adaptive Sync in the GPU settings for smoother motion. Consider external audio if higher sound quality is required.
