Dahua 24.5" IPS Gaming Monitor 200Hz 0.5ms | Full HD | LM25-E231BN
The Dahua DHI-LM25-E231BN is a 24.5-inch Full HD (1920 × 1080) gaming monitor with an IPS panel, a 200 Hz refresh rate and a 0.5 ms (OD) response time. It supports HDR10 and adaptive sync, and both its DisplayPort 1.4 and HDMI 2.0 inputs run at 1920 × 1080 at 200 Hz.


200 Hz for smooth motion: At 200 Hz the screen refreshes 200 times per second, so fast movement in shooters and racing games looks smoother than on a standard 60 Hz monitor. Your graphics card and game need to output that frame rate to use the full 200 Hz.
Fast response time: Dahua rates the response time at 0.5 ms with overdrive (OD) and 1 ms MPRT, which reduces blur and ghosting behind moving objects.
200 Hz on both inputs: Both the DisplayPort 1.4 and the HDMI 2.0 input support 1920 × 1080 at 200 Hz, so a PC or a console on HDMI gets the same maximum refresh rate. An audio output lets you plug in headphones or speakers.
IPS panel, HDR10 and adaptive sync: The IPS panel has 178° viewing angles, 350 cd/m² typical brightness, a 1000:1 contrast ratio and an 85% NTSC color gamut. HDR10 support and adaptive sync help with contrast in HDR content and with tearing and stutter in games.
Slim bezels and VESA mount: The frame is 6.98 mm on the top and sides, and the monitor can go on a wall or arm with a 100 × 100 mm VESA mount. Software low blue light mode is built in for long sessions.
Good to know
The stand adjusts for tilt only (-5° to 20°); no height, swivel or pivot adjustment is listed by Dahua. The monitor runs from an external 12 VDC 3 A power adapter and has no built-in speakers listed.
