## Long description

The OMEN by HP 31.5" QHD LCD 2560 x 1440 is a 31.5-inch gaming monitor with a 2560 x 1440 (QHD) resolution and an IPS LCD panel. Designed for gaming and general multimedia use, it delivers wide 178° viewing angles, a fast 165 Hz refresh rate and a 1 ms response time to reduce blur and motion artefacts. The matte display surface reduces glare and the flat 16:9 screen supports a clear, consistent image across the panel. The monitor is finished in black and supports VESA mounting and ergonomic height adjustment for flexible placement.
Advantages
This monitor combines a high refresh rate and low response time to provide smooth motion and reduced ghosting during fast-paced games.

An IPS panel ensures consistent colors and wide viewing angles, while a matte screen finish minimizes reflections in various lighting conditions. VESA compatibility and adjustable height help integrate the display into a multi-monitor setup or ergonomic workstation.
Suitable for
 Competitive and fast-paced PC gaming that benefits from 165 Hz refresh and 1 ms response
 Single-player and open-world games where higher resolution enhances visual detail
 Content consumption such as movies and streaming thanks to IPS viewing angles
 General productivity and multi-window workflows that use the 31.5" screen area

How to use

Adjust the height to a comfortable eye level and use the matte finish to reduce reflections. If your setup lacks built-in speakers or a USB hub on the monitor, connect external audio and peripheral devices directly to your PC or to external hubs.
Usage recommendations
For optimal gaming performance, use a capable GPU and the correct video cable to enable 2560 x 1440 at 165 Hz. Calibrate color and brightness settings to suit your lighting conditions, and allow the monitor to run at native resolution for the best image clarity.
