## Long description

27" LED IPS monitor with Full HD 1920 × 1080 resolution, 16:9 aspect ratio and 144 Hz refresh rate designed for smooth, clear on-screen images. The display combines an IPS panel for wide viewing angles and accurate colour reproduction with a fast 1 ms response time to minimise motion blur and ghosting. Built-in low blue light technology helps reduce eye strain during extended use.
Advantages
The 144 Hz refresh rate delivers noticeably smoother motion compared with standard 60 Hz displays. IPS panel technology ensures consistent colours and wide viewing angles, making the monitor suitable for general multimedia, office work and casual gaming. A 1 ms response time reduces visible blur in fast-moving scenes, while low blue light technology supports more comfortable long-term viewing. Energy consumption is modest, with typical power usage around 21 kWh/year and 27 W during operation.

How to use
Connect the monitor to your computer using the appropriate video cable supported by your graphics card.

Use on-screen display controls to calibrate brightness, contrast and color settings as needed. Enable low blue light mode from the monitor menu for reduced blue light emission during prolonged sessions.
Recommendations
For optimal smoothness in games and video, ensure your graphics card can output high frame rates close to 144 fps at 1920 × 1080. Place the monitor at an appropriate distance and height to reduce neck and eye strain, and combine low blue light mode with regular breaks to support comfortable long-term use.
