Dahua 27" 2K QHD Gaming Monitor 200Hz 1ms | IPS | HDR10 | LM27-E331Y
The Dahua LM27-E331Y (DHI-LM27-E331Y) is a 27-inch flat IPS gaming monitor with QHD 2560 × 1440 resolution, a refresh rate of up to 200 Hz and a 1 ms MPRT response time. It covers 95% of the DCI-P3 color space, supports HDR10 and connects through two HDMI 2.1 and two DisplayPort 1.4 inputs.
QHD resolution on 27 inches: 2560 × 1440 pixels on a 27-inch screen gives a pixel pitch of 0.2331 mm, which is more pixels and finer detail than a 1920 × 1080 monitor of the same size.
Up to 200 Hz with 1 ms MPRT: Over DisplayPort 1.4 the monitor runs at 2560 × 1440 at up to 200 Hz, and over HDMI 2.1 at up to 144 Hz. Together with the 1 ms MPRT response time, fast motion in games looks smoother with less blur.
95% DCI-P3 color and HDR10: The IPS panel displays 1.07 billion colors (8 bits + FRC) and covers 95% of DCI-P3, and HDR10 content is supported. This means HDR10 games and videos from a compatible PC or console can be shown in HDR mode.
Anti-glare screen: The screen surface has an anti-glare treatment (haze 25%, 3H hardness), which reduces reflections from room lights and windows.
Tilt stand and VESA mounting: The included stand tilts from -5° to +15°. For wall or arm mounting, the monitor has a 100 × 100 mm VESA pattern.
Good to know
To get 200 Hz at 2560 × 1440 you need a DisplayPort connection; HDMI is limited to 144 Hz at this resolution. A DisplayPort cable is included in the box. The stand adjusts for tilt only. The monitor uses an external 12 V power adapter (included).
What's in the Box
Power adapter, bracket, base, DisplayPort cable, user manual (QR code), legal and regulatory information, energy label.
