The Dahua DHI-LM27-E431A is a 27-inch UHD monitor built for users who want both high-end image quality and exceptionally smooth motion. With a 3840 × 2160 resolution on an IPS panel, it delivers sharp, detailed visuals with consistent clarity and lifelike color reproduction—making it a strong choice for competitive gaming, video editing, and everyday professional content creation.
A standout advantage of this monitor is its dual refresh rate mode, designed to match different performance needs. You can switch between 4K at 160Hz for high-fidelity visuals and Full HD at an incredible 320Hz for maximum motion smoothness. This flexibility helps when you’re balancing cinematic detail in UHD content versus the ultra-fast responsiveness required for esports and high-frame-rate gameplay.
To reduce motion blur and improve clarity during fast movement, the DHI-LM27-E431A supports rapid 1ms MPRT and 0.5ms OD response performance. The result is cleaner transitions in action scenes, smoother tracking in FPS titles, and a more responsive feel during competitive play—especially beneficial when your system is capable of pushing high frame rates.
Color accuracy is a key strength of this display. It supports a 98% DCI-P3 color gamut and offers 1.07 billion color support (8-bit + FRC), helping gradients look smoother and colors appear more natural. Combined with HDR10, the monitor enhances contrast and brings out brighter highlights and richer tones, which is useful for HDR-capable games, photo work, and video timelines where visual depth matters.
The IPS panel technology provides wide 178° viewing angles, so the image remains consistent even when viewed from different positions—ideal for collaborative work, shared viewing, or multi-person setups. The monitor also features a matte finish with 25% haze anti-glare coating to help reduce reflections, supporting comfortable long sessions whether you’re editing, designing, or gaming late into the night.
For future-ready performance, the monitor includes 2× HDMI 2.1 and 2× DisplayPort 1.4 ports. This makes it easier to connect modern gaming PCs, consoles, and high-performance workstations while maintaining high refresh rate support in both UHD and FHD modes. An audio-out jack is also provided for quick connection to speakers or headphones, helping you keep your desk setup clean and functional.
Comfort matters during long gaming or editing sessions. The DHI-LM27-E431A includes hardware-level blue light protection to support eye comfort, along with an anti-glare coating for reduced glare. For ergonomics, it offers adjustable tilt (-5° to +15°) and supports 100×100mm VESA mounting, allowing you to position the screen at a comfortable viewing angle. In terms of efficiency, it draws 26W (basic) up to 40W (max), which is helpful for reducing power usage during daily use.
Designed for long-term reliability, the monitor is rated for up to 30,000 hours of use. It also comes with a 3-year warranty, giving buyers confidence for both home and professional environments where dependable performance is essential.
If you’re looking for a 27-inch UHD IPS monitor that can deliver competitive-grade motion smoothness through 320Hz FHD mode while still offering UHD 160Hz for detailed visuals, this model is a practical and versatile option. It’s especially suitable for esports players who want fast response and high refresh, and for creators who need strong color coverage, HDR10 support, and a comfortable viewing experience for extended workflows.
