The Dahua Monitor Lineup in Bangladesh, Explained

A Security Brand That Also Builds PC Monitors

Dahua is best known worldwide for CCTV and security cameras, but it also runs a genuinely wide PC monitor lineup under the DHI-LM model prefix - the number after "LM" is the screen size, so an LM27 model is 27", an LM43 is 43", and so on. Rather than separate sub-brands like some competitors, Dahua spreads its range from basic 18.5" office displays up to a 55" 4K screen, with a full gaming line and curved ultrawides in between - all covered here in one collection.

Entry & Everyday Displays

The DHI-LM19-A202Y 18.5" HD Monitor is the smallest and most affordable screen in the range, built for basic document and browser use. The DHI-LM22-A201YFS 21.45" 100Hz FHD steps up to full FHD resolution with a 100Hz refresh rate for smoother everyday scrolling, and the DHI-LM24-B201E 23.8" 100Hz FHD brings that same everyday spec to a larger 23.8" screen.

Mainstream Gaming: 120Hz-180Hz FHD

This is the largest single group in Dahua's range - genuine fast-refresh FHD gaming panels at accessible pricing. The DHI-LM24-A221Y 23.8" 144Hz FHD and DHI-LM24-B221 24" 144Hz FHD both hit 144Hz at roughly the same size. The LM25-B221B 24.5" 120Hz FHD and DHI-LM25-E231 25" 180Hz FHD push refresh rate further at a similar screen size. At 27", three close variants - the DHI-LM27-A221Y, DHI-LM27-B221, and DHI-LM27-B221S - all share the same 27" 144Hz FHD core spec, with small pricing differences between them coming down to chassis and feature variations rather than a meaningfully different gaming experience. Topping this group, the LM25-E241A 24.5" 320Hz 1ms is the fastest FHD panel in Dahua's entire lineup here.

QHD: Sharper Resolution, With and Without Gaming Speed

The DHI-LM24-P301A 23.8" 2K QHD brings QHD sharpness to everyday and office use without a gaming-tier refresh rate. On the gaming side, the DHI-LM27-E341AY 27" QHD 275Hz and DHI-LM27-E341A 27" QHD 240Hz both combine sharp QHD resolution with genuinely fast refresh rates, the 275Hz model edging out the 240Hz for players who want every extra frame.

Curved Ultrawide & Large-Format 4K

For an immersive, wider field of view, the DHI-LM30-E330CA 30" 200Hz WFHD Curved and DHI-LM34-E330CA 34" WQHD 200Hz Curved both wrap a curved panel around your view at a fast 200Hz. For sheer screen size instead, the DHI-LM43-F400 43" 4K UHD and DHI-LM55-F400 55" 4K UHD are large-format 4K displays built to double as a desktop monitor or a living-room/meeting-room screen.

Flagship: QD-OLED and the 49" DQHD Ultrawide

The LM27-GO34A 26.5" 2K QHD QD-OLED 240Hz is Dahua's OLED gaming flagship - true per-pixel blacks and near-instant response time alongside a fast 240Hz refresh rate. The DHI-LM49-EW410CA 49" DQHD Curved is the other flagship, and a genuinely different product from the rest of the range - a 5120x1440 DQHD panel on a 32:9 curved screen, effectively equivalent to two 27" QHD monitors side by side with no bezel gap in the middle. It runs a 120Hz refresh rate, 1ms response time, 99% sRGB colour coverage with Delta E < 2 accuracy, supports Picture-in-Picture and Picture-by-Picture modes for running two input sources at once, and includes a USB-C port with 65W power delivery for charging a connected laptop through the same cable carrying video.

Dahua Monitor Price in Bangladesh: Tiers Compared

Every Dahua monitor currently sold here, broken into price tiers with the real feature trade-off at each step:

Entry Tier: Tk 8,600 - Tk 14,600

The DHI-LM19-A202Y 18.5" HD at Tk 8,600 is the most affordable Dahua display sold here. The DHI-LM22-A201YFS 21.45" 100Hz FHD (Tk 10,000), DHI-LM24-A221Y 23.8" 144Hz (Tk 13,500), and DHI-LM24-B201E 23.8" 100Hz (Tk 13,599) all sit close in price - the 144Hz A221Y is the better pick of the three if even light gaming matters, since it costs barely more than the 100Hz options. The DHI-LM24-B221 24" 144Hz (Tk 13,800) and LM25-B221B 24.5" 120Hz (Tk 14,600) close out this tier as genuine entry-gaming panels.

Mainstream Gaming Tier: Tk 16,700 - Tk 21,000

The DHI-LM25-E231 25" 180Hz (Tk 16,700) is the entry point into this tier. The three close 27" variants - DHI-LM27-A221Y (Tk 17,000), DHI-LM27-B221 (Tk 17,999), and DHI-LM27-B221S (Tk 18,000) - all deliver the same 27" 144Hz FHD experience, so picking between them mostly comes down to whichever is in stock. At the top, the LM25-E241A 24.5" 320Hz 1ms (Tk 21,000) is the fastest FHD panel Dahua sells here, for players who prioritise refresh rate above resolution or size.

QHD Tier: Tk 26,000 - Tk 36,500

The DHI-LM24-P301A 23.8" QHD (Tk 26,000) is the entry point into sharper QHD resolution, without a gaming-tier refresh rate. The DHI-LM27-E341AY 27" QHD 275Hz (Tk 32,999) and DHI-LM27-E341A 27" QHD 240Hz (Tk 36,500) both add genuine gaming-grade refresh rates on top of QHD sharpness - interestingly the 275Hz model is priced lower than the 240Hz one here, so it's the better value of the pair if both are in stock.

Curved Tier: Tk 37,500 - Tk 48,500

The DHI-LM30-E330CA 30" 200Hz WFHD Curved (Tk 37,500) is the entry point into Dahua's curved ultrawide range. The DHI-LM34-E330CA 34" WQHD 200Hz Curved (Tk 48,500) steps up in both size and resolution while holding the same 200Hz refresh rate, worth the difference if immersive width and sharper QHD detail both matter to you.

Large-Format & Flagship Tier: Tk 55,000 - Tk 98,000

The DHI-LM43-F400 43" 4K UHD (Tk 55,000) is the most affordable large-format 4K screen in the range. The LM27-GO34A QD-OLED 240Hz (Tk 80,000) and DHI-LM55-F400 55" 4K UHD (Tk 82,000) sit close in price but serve very different purposes - one is a compact OLED gaming flagship, the other the largest flat screen in the lineup. At the very top, the DHI-LM49-EW410CA 49" DQHD Curved (Tk 98,000) is the most expensive Dahua monitor here - covered in full detail above.
