Dahua DHI-LM25-E231 24.5-inch FHD IPS 180Hz Gaming Monitor

Exact model and screen size

The Dahua DHI-LM25-E231 is a gaming monitor in the LM25 product family. Dahua's exact-model specification lists a 24.5-inch display, while local sellers commonly market it in the 25-inch class. The exact model code is DHI-LM25-E231; “25-inch” is the market class rather than part of the MPN. The catalog now uses the exact model in model and manufacturer-part-number fields while retaining the existing product URL. The Dahua brand record is used instead of the generic “Others” brand.

Dahua specifies a flat IPS panel with E-LED backlight, Full HD resolution of 1920 × 1080 and a 16:9 aspect ratio. It supports a maximum refresh rate of 180Hz, typical brightness of 250 nits, static contrast of 1000:1 and a 1ms MPRT response-time figure. The response time is MPRT; no separate overdrive response-time value is claimed for this exact E231 model.

A 24.5-inch Full HD panel is a familiar size for gaming and general desktop use. It gives a wide-screen workspace for games, browsing and everyday applications, while the 180Hz specification can display frequent updates when the connected PC produces enough frames. The source computer and cable must support the selected resolution and refresh mode; the monitor does not create additional game frames.

Panel, color and image characteristics

Dahua lists 72% NTSC color support for the exact DHI-LM25-E231. Star Tech and other Bangladesh retailer listings state 85% NTSC. This is a material specification conflict, so the catalog records Dahua's official 72% value and notes the retailer claim separately. It does not convert either figure to sRGB or imply an independent colorimeter result. Buyers who require known color coverage for design work should request clarification for the exact revision or use a measured calibration report.

The manufacturer lists 178° horizontal and vertical viewing angles and 16:9 aspect ratio. The black finish and three-sided narrow bezel appear in the supplied product images and retailer descriptions. Viewing angle figures are manufacturer specifications; they do not mean color and contrast remain identical at every viewing position. The monitor uses an anti-glare surface according to local product listings.

The 250-nit typical brightness is suitable for ordinary indoor desktop conditions. Dahua's page does not establish HDR support, and Ryans explicitly lists HDR as unavailable. The listing therefore does not present the product as an HDR monitor. For brighter rooms or HDR content, compare measured brightness and the exact panel revision before purchase.

180Hz refresh and motion response

Dahua specifies up to 180Hz refresh and 1ms MPRT response time. A higher refresh rate can make supported motion appear smoother than 60Hz, but the computer must send frames at the selected rate. Set the display to 1920 × 1080 and confirm 180Hz in the operating system or graphics control panel after connecting. The source graphics card, port, cable, driver and game settings all affect the available mode.

Dahua describes Adaptive Sync, and Star Tech identifies it as FreeSync. Adaptive sync requires compatible graphics hardware and software settings. The exact variable-refresh range is not stated in the reviewed source pages. Buyers should confirm compatibility for their GPU and connection. The 1ms MPRT figure is a specification, not a guarantee that all transitions appear blur-free in every picture mode.

The exact E231 model is distinct from related revisions such as E231B or E231BN. Specifications for those variants can differ, including refresh rate, brightness, tilt range and weight. This catalog record stays tied to DHI-LM25-E231 and does not import the sibling models' 200Hz or 300-nit details.

Video, USB and audio connections

Dahua lists one DisplayPort 1.4 input, one HDMI 2.0 input, one USB service port for firmware upgrades only and one audio-out jack. The USB port is not USB-C video input, a USB hub or a general-purpose data passthrough port. Star Tech's table places the service USB under a USB Type-C label, but Dahua's official specification identifies it only as a USB upgrade port. The product content uses the manufacturer's description.

The HDMI and DisplayPort inputs connect computers and compatible video sources. Dahua's specification names those port versions but does not publish a detailed per-port timing table in the reviewed summary. Use a certified compatible cable and check that the computer exposes 1920 × 1080 at 180Hz. The single HDMI input can connect one HDMI source at a time; users with several consoles or PCs may need an external switch.

There are no built-in speakers. The 3.5mm audio output can connect headphones or external speakers when audio is delivered through the selected video connection. The monitor should not be described as having built-in audio playback. A separate speaker system may be needed for sound.

Stand, mounting, dimensions and weight

The stand supports tilt from −5° ±2° to +15° ±2°. Dahua lists no swivel, pivot or height adjustment for this model. The monitor supports a 100 × 100 mm VESA mount. The package includes the display base and other listed accessories; verify the box contents with the seller. The rear product image shows the input area and mounting region.

Dahua lists net weight as 3.6 kg and gross weight as 4.7 kg. The manufacturer marks dimensions without the stand as TBD and separately lists a package size of 620 × 115 × 475 mm. That package measurement is not the monitor's physical dimensions. The catalog therefore labels it as carton size and leaves unit width, height and depth unknown until Dahua publishes them.

A Kensington or security lock slot is not listed in the official specification reviewed. The black monitor can be positioned using its supplied tilt stand or a compatible VESA arm. Check the arm's load rating, screw length and the exact mounting manual before installation.

Power, warranty and Bangladesh price

Dahua lists an external adapter with DC 12V, 3A input, maximum consumption of 36W and standby use below 0.5W. The standard accessory list includes an adapter and power cable. Use the supplied compatible adapter and follow the manual rather than choosing a replacement solely by connector fit.

Bangladesh retailers list a three-year warranty. The reviewed seller pages do not provide one consistent component-by-component coverage table, so the catalog records three years as retailer-listed coverage and recommends confirming the warranty provider, claim route and exclusions on the invoice and warranty card. Physical damage and other exclusions may be treated differently from manufacturing defects.

Current seller prices differ. Star Tech lists ৳15,000, while TechLand shows a lower displayed offer around ৳16,000 on its product page and later copy elsewhere says ৳16,700; Ryans shows ৳16,200 special and ৳17,250 regular. Star Tech shows a regular price of ৳19,000. The catalog variant uses ৳15,000 as the lowest current cash-price observation and records a ৳15,000–৳19,000 comparison interval. These are dated retailer observations, not a BiponiBD offer or stock promise. Confirm current checkout price, availability, delivery and warranty with the chosen seller.

No barcode, GTIN or country-of-origin value was established by the official model page or retailer listings reviewed. Those fields remain unknown rather than being inferred from the brand or product code.

Who this monitor suits

The DHI-LM25-E231 suits buyers seeking a Full HD IPS gaming display with a high listed refresh rate, Adaptive Sync, a DisplayPort input and a tilt stand. It can also serve for everyday browsing and office tasks. Its 24.5-inch official diagonal is often described as a 25-inch model class in Bangladesh retail listings.

Its trade-offs are a tilt-only stand, 250-nit typical brightness and no built-in speakers. The USB connection is limited to firmware upgrade according to Dahua. The color-gamut value differs between the Dahua specification (72% NTSC) and Bangladesh retailer descriptions (85% NTSC). Users who need accurate color coverage, height adjustment, USB docking or built-in audio should compare those requirements carefully before ordering.
