Dahua DHI-LM27-B221S 27-inch FHD IPS 144Hz 1ms Commercial Monitor

Dahua DHI-LM27-B221S Price in Nepal & Overview

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.

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.

Does the Dahua DHI-LM27-B221S support 144Hz on both HDMI and DisplayPort?
Yes. Both the HDMI 2.0 and DisplayPort 1.4 inputs support the full 144Hz refresh rate at 1920×1080 resolution — no compromise needed regardless of which port you use.

Can the Dahua DHI-LM27-B221S be wall mounted?
Yes. It supports VESA 75x75mm wall mounting. The wall mount bracket is sold separately as an optional accessory.

Not ideally. Its 72% NTSC color gamut is suitable for everyday office and multimedia use but falls below the color accuracy standard most design and photo editing workflows require. A monitor with 95%+ DCI-P3 or 99% sRGB coverage would be more appropriate for color-critical work.
