The Dahua DHI-LM27-B221S is a 27-inch FHD commercial monitor designed for office workstations, dual-monitor productivity setups, and casual gaming.
Available at our Kathmandu showrooms for a special offer price of Rs. 21,000 (discounted from the regular retail price of Rs. 26,500), it delivers a 144Hz refresh rate and 1ms MPRT response time on an IPS panel — a combination more commonly found in monitors costing significantly more.
Two honest things to know before buying: at 81.59 PPI, a 27-inch FHD panel has lower pixel density than a 24-inch FHD display, which means text and fine detail are slightly less sharp up close at normal desktop distances. Also, the 72% NTSC color gamut (approximately 52% DCI-P3) is adequate for general office and multimedia use but falls short of what professional photo or video editors require — for color-critical work, a monitor with 95%+ DCI-P3 or 99% sRGB coverage would be a better fit.

Technical Specifications

Who This Monitor Is For

This monitor suits office workers, students, and casual gamers who want a large, smooth 144Hz display at an accessible price point.
The 27-inch IPS panel with 178° viewing angles is comfortable for multi-hour work sessions, and the inclusion of both HDMI 2.0 and DisplayPort 1.4 — both running at full 144Hz — means it connects cleanly to both modern PCs and gaming consoles without an adapter. The built-in speakers and audio out keep your desk tidy without requiring external audio gear for everyday use.
However, with 72% NTSC color coverage and 250 nits brightness, it’s not the right choice for professional photo editing, color grading, or use in brightly lit rooms where a higher-brightness panel would fare better.

Frequently Asked Questions

What is the price of the Dahua DHI-LM27-B221S in Nepal?
The Dahua DHI-LM27-B221S is priced at Rs. 21,000 at Alam Tech, Kathmandu (discounted from Rs. 26,500), including a 3-year warranty.

Yes. It supports VESA 75x75mm wall mounting. The wall mount bracket is sold separately as an optional accessory.

• Dell S2425H 24-inch 100Hz Full HD IPS Monitor — a more compact alternative with higher pixel density at a lower price point.

The Dahua DHI-LM27-U401A is a 27-inch professional commercial monitor designed for software developers, UI/UX designers, and business analysts who require absolute visual clarity. Stepping up to a full 4K UHD (3840×2160) resolution on an In-Plane Switching (IPS) panel provides four times the pixel density of standard 1080p screens, resulting in ultra-sharp text and precise code rendering. The flat ELED display maintains a consistent 1000:1 contrast ratio and covers 85% of the NTSC color gamut, ensuring accurate asset reproduction across a wide 178-degree viewing angle without the color washing typical of budget TN panels.

Single-Cable Workflow & Connectivity Integration

To minimize desk clutter in modern workspaces, the I/O interface includes a high-capacity USB Type-C port delivering 65W of reverse charging. This allows users of modern ultrabooks like the Apple MacBook Air or the Lenovo IdeaPad Slim 3 Ryzen 7 to transmit 4K video, transfer data, and charge their laptop simultaneously using one single cable. The logic board also houses standard HDMI 2.0, DisplayPort 1.4, multiple USB-A downstream ports, and a dedicated audio out. While the 60Hz refresh rate and 5ms response time deliver highly responsive UI navigation and data entry, this configuration is strictly built for professional productivity pipelines rather than high-framerate competitive gaming.
