Dahua LM27-B221B 27" FHD IPS 144Hz 1ms Monitor
The Dahua LM27-B221B 27" FHD IPS 144Hz 1ms Monitor is built for users who want smooth, colour-accurate visuals without the bulk of a heavy desktop setup. Its IPS panel and 144 Hz refresh rate make it equally suited to designers who need consistent colour reproduction and gamers or productivity users who benefit from reduced motion blur. Low blue light technology and a 178° wide viewing angle mean it can be used comfortably across extended sessions and shared viewing situations.
Why this product
144 Hz refresh for visibly smoother motion
The 144 Hz refresh rate delivers a tangible improvement in image smoothness compared with standard 60 Hz panels, reducing stutter during fast-moving content.
IPS panel with 178° viewing angles
IPS technology provides accurate, consistent colour reproduction from virtually any angle — 178° horizontally and vertically — so colours do not shift when you move off-centre.
1 ms MPRT response time
The 1 ms MPRT response time minimises image blurring and ghosting during fast-moving scenes, keeping on-screen detail sharp.
85% NTSC wide colour gamut
The 85% NTSC colour gamut and 16.7 M display colours give designers and content reviewers a broader, more accurate palette to work with.
Low blue light for extended comfort
Built-in low blue light technology reduces eye strain during long viewing sessions without requiring external filters or software.
VESA-compatible for flexible mounting
The 100 × 100 mm VESA mount pattern means it can be moved off the included stand and fitted to a wall mount or monitor arm.

Best for
- Designers and photographers who need consistent, wide-gamut colour across the full screen — the IPS panel and 85% NTSC gamut serve colour-critical work.
- Gamers and fast-content viewers who want a fluid 144 Hz experience with minimal ghosting at a 27" FHD size.
- Multi-display or space-conscious setups — the ≥90% screen-to-body ratio and thin 57.2 mm depth keep the footprint compact, and VESA mounting frees up desk space.
- Users sensitive to eye strain during long sessions, thanks to the built-in low blue light mode.
- Low-power environments — typical consumption of 25 W and standby below 0.5 W keep running costs modest.
Trade-offs
- 4K or high-resolution workflows — the native resolution is 1920 × 1080, so fine-detail work that benefits from higher pixel density will be limited.
- Users needing height or swivel adjustment — the stand offers tilt only; ergonomic flexibility requires a separate VESA mount.
- Audio-out-only connectivity — there is one audio output port but no listed audio input, built-in speakers, or USB ports.
- Warm or humid environments — operating range is 0 °C to 40 °C and up to 85% relative humidity (non-condensing); it is not rated for harsh or industrial conditions.
