Dahua DHI-LM22-L200V 21.45-inch FHD 100Hz IPS Monitor

Dahua DHI-LM22-L200V is a 21.45-inch Full HD IPS monitor with an E-LED backlight and a manufacturer-listed maximum refresh rate of 100Hz. Dahua lists 300 cd/m² typical brightness, 1000:1 contrast, 72% NTSC gamut, HDMI and VGA, tilt, VESA mounting and support for continuous 24/7 operation. Local seller stock and prices vary; verify the exact unit and written warranty before purchase.

Overview and intended use

The Dahua DHI-LM22-L200V is a 21.45-inch Full HD monitor in Dahua’s Project Series. Dahua’s Bangladesh product page describes it as an FHD LED monitor and identifies IPS technology, an E-LED backlight, 1920 × 1080 resolution and a maximum 100Hz refresh rate. The manufacturer also highlights support for continuous 24/7 operation. These specifications make it a candidate for office desks, monitoring counters, classrooms, reception areas and home computers that need a clear Full HD image. It is still a standard 16:9 desktop display, not a touch monitor or an ultrawide panel. The exact model suffix matters: similar Dahua LM22 products may have different panels, refresh rates or stands. Match DHI-LM22-L200V on the carton and invoice, then confirm the seller’s current stock and warranty terms before ordering.

Full HD workspace and screen size

The 21.45-inch panel uses a native resolution of 1920 × 1080 pixels and a 16:9 aspect ratio. Full HD provides room for documents, browser tabs, spreadsheets, video meetings and common desktop applications without the lower pixel count of HD displays. Set the computer to 1920 × 1080 for the sharpest text and check that the graphics output supports the desired 100Hz mode. Screen scaling can make small text easier to read, though it also changes the effective workspace. A 21.45-inch screen is a practical middle ground for desks where a 24-inch monitor would be too large. It is not 4K, and users who regularly inspect high-resolution imagery or place many large windows side by side may prefer a larger or higher-resolution display.

IPS panel, backlight and colour

Dahua specifies an IPS panel with E-LED backlighting, typical brightness of 300 cd/m² and a 1000:1 contrast ratio. It lists a 72% NTSC colour gamut and 8-bit colour depth. IPS technology is commonly selected for broad viewing angles and consistent everyday colour compared with basic TN panels. The manufacturer states 178° horizontal and vertical viewing angles; this is a listed specification and does not mean that brightness or colour is perfectly unchanged from every position. The gamut figure is NTSC-based and should not be treated as a measured sRGB calibration result. Dahua does not provide a colour-calibration report on the cited product page. The monitor can suit routine office and media use, while professional photography, print proofing and colour-critical design require a measured and calibrated display.

Refresh rate and response-time wording

Dahua lists a maximum 100Hz refresh rate and a typical response time of 1ms. A compatible computer and connection may allow smoother pointer movement, scrolling and motion than a conventional 60Hz setting. The actual mode depends on the graphics device, cable, operating system and selected display timing. The manufacturer’s 1ms figure is labelled typical; it is not a full set of measured pixel transitions, input-lag results or a guarantee that motion blur disappears. Star Tech, Dear IT Solution, Computer Village and Tech Land show the same headline 100Hz and 1ms specification. Use the monitor’s supported resolution and refresh options shown by the connected system, and do not assume that every application or video runs at 100 frames per second.

HDMI, VGA and audio connection details

The Dahua specification lists one HDMI input and one VGA input. HDMI is the straightforward digital connection for most recent desktops and laptops with a compatible port. VGA supports older computers and analog video sources. The official product specification lists output as N/A. Some retailer descriptions, including Star Tech, mention an audio output, so the audio-port detail is inconsistent across pages and is not asserted as a confirmed feature here. The exact unit and its rear-panel labels should be checked if a headphone or speaker connection is important. The product is not listed with DisplayPort, USB-C, a USB hub or multiple HDMI inputs. VGA carries video rather than audio. If the computer lacks HDMI or VGA, verify the correct adapter and supported 1920 × 1080 at 100Hz mode before purchasing.

Stand adjustment and mounting

Dahua lists a tilt range from approximately -5° to +15° and VESA mounting support. The cited specifications do not describe height, swivel or pivot adjustment, so the stand should be considered tilt-adjustable only unless the seller confirms otherwise for the supplied unit. Adjust the tilt to keep the panel facing the user and reduce reflections. A separate VESA arm or wall bracket can provide more positioning options, but confirm the mounting pattern, screw depth, monitor weight and bracket capacity before installing it. Dahua lists 2.3kg net weight and 3.4kg gross weight. The package and shipping weight are different from the monitor-only weight. Place the stand on a stable surface and leave room for the power lead and ventilation.

Dimensions, power and daily operation

Dahua lists a product dimension of 493.1 × 384.2 × 190mm and labels the measurement as without the base. Retailer specification tables repeat the same measurement, although the wording and interpretation are not fully clear. Treat it as a listing reference and measure the actual unit if a shelf or mounting clearance is critical. The official power specification is 12V DC, 2A, with standard consumption of 22W and standby consumption below 0.5W. Use the supplied adapter and check its output label before connecting it; do not substitute a visually similar power supply without matching voltage, current, polarity and connector. Dahua lists 0°C to 40°C operating temperature and 10% to 90% humidity. Keep the monitor dry, ventilated and away from direct heat.

Included accessories and 24/7 capability

Dahua lists an HDMI cable, power adapter and base as standard accessories, with a hanging bracket as optional. Retailer bundles can vary, so inspect the carton contents and invoice rather than assuming every item is included in every sale. The manufacturer highlights suitability for continuous 24/7 operation. This describes a product capability on the official listing; installation quality, ambient temperature, ventilation and power stability still affect real service life. Keep the vents clear, use a stable electrical outlet and follow the supplied instructions. The optional bracket is not the same as a confirmed in-box wall mount. Ask the seller to identify the exact bundle and warranty provider before purchase, particularly for institutional deployments where accessory count, installation method and uninterrupted operation matter.

Warranty, stock and observed seller listings

Dahua’s official product page provides specifications but no Bangladesh retail price. Star Tech showed Out Of Stock with a price marked To be announced; Ryans and Computer Village also showed the exact model out of stock when checked. Tech Land displayed ৳8,800 and explicitly stated it was out of stock. Dear IT Solution showed In Stock at ৳9,200 during the direct page check. This was one directly verified in-stock seller, so it is stored as a single observed listing and is not presented as a market range or as a BiponiBD store offer. Several pages list a three-year warranty; confirm the local provider, coverage, exclusions and claim process in writing. Stock and prices change, so recheck the seller before ordering.

Who may find it useful

This monitor may suit an office user who wants Full HD text and a moderate desktop footprint, a student attending online classes, a home user browsing and watching video, or a control-room operator who values the manufacturer’s 24/7-use claim. HDMI and VGA provide a path for both newer and older systems, and the IPS panel with 178° listed viewing angles can help when more than one person looks at the screen. It may be less suitable for buyers who need a height-adjustable stand, built-in speakers, USB-C docking, DisplayPort, multiple digital inputs, hardware-calibrated colour or a resolution above Full HD. Competitive gamers should compare measured input lag, adaptive-sync support and real motion performance, because the headline refresh and response numbers do not answer those questions.

Setup and image checks

Before setup, check that the label says DHI-LM22-L200V. Connect HDMI when available, select the monitor’s HDMI input, and set 1920 × 1080 in the computer’s display settings. If 100Hz is available, select it and confirm the picture remains stable. Use VGA only where needed and remember that it does not carry audio. Tilt the screen toward the seated viewing position, set brightness for the room and avoid strong reflections. Confirm the adapter rating against the supplied unit, and route cables so they cannot pull the stand. If the screen stays blank, check input selection, cable seating, source output and power before concluding that the monitor is defective. Test the display, ports, tilt mechanism and any supplied cable promptly within the seller’s return period.

Care, cleaning and safe mounting

Switch off and unplug the display before cleaning. Use a clean, soft cloth and follow the manufacturer’s care instructions; avoid spraying liquid directly onto the panel or using abrasive cleaners. Keep liquids away from the screen edges, adapter and power connector. When using a VESA arm, confirm the bracket and fasteners match the monitor and do not force a screw that feels too long. Support the panel while attaching it so it cannot fall. The listed 2.3kg net weight is only one input to mount selection; verify the arm’s rated load and movement range. Leave sufficient space around the monitor and power adapter for airflow. These practical steps help protect the panel and connectors during ordinary office and home use.

Buying checklist and source limits

Before paying, reconfirm the exact model, physical stock, final price, delivery cost, return window and written warranty. Ask whether the retailer’s advertised audio output applies to the supplied unit because the manufacturer lists outputs as N/A while one seller lists audio output. Confirm included HDMI cable, adapter and base, and whether any VESA bracket must be purchased separately. The official Dahua page is the primary source for panel, resolution, refresh, power and accessory specifications. Retail pages were used to check Bangladesh stock and retailer warranty statements. Retailer descriptions contain promotional language and occasional inconsistencies, so unsupported claims such as built-in speakers or universal gaming suitability have not been repeated. The one observed ৳9,200 listing is time-specific and is not a promise of availability or a BiponiBD offer.

Comparison with common alternatives

When comparing monitors, check panel type, native resolution, refresh rate, brightness, connection count, stand movement, mounting and warranty as a complete set. The LM22-L200V combines a 21.45-inch IPS Full HD panel, 100Hz maximum rate, one HDMI and one VGA input, tilt and VESA support. A 24-inch panel may offer a larger image, while a model with USB-C may reduce cable clutter for laptops. A model with built-in speakers may avoid separate audio equipment, though the LM22-L200V’s audio output listing is inconsistent and its built-in speaker specification is not confirmed. A higher refresh rate alone does not establish lower input lag or better motion clarity. Choose based on the ports and ergonomics the actual desk and computer need, and compare exact model codes instead of relying on a similar product family name.

Image quality expectations

At native Full HD, the monitor can render detailed text and standard 1080p video at its supported aspect ratio. A 300 cd/m² typical brightness specification suits many indoor work areas, though strong sunlight or bright overhead lighting can reduce perceived contrast. A 1000:1 contrast ratio is a conventional LCD specification and does not indicate OLED-like black levels. The listed 72% NTSC gamut describes a colour range using that colour-space reference; it does not certify factory calibration or a particular sRGB coverage. IPS viewing-angle specifications are useful context, but viewing distance, ambient light, image mode and individual perception still affect the result. For colour-critical work, ask for a measurement report or select a monitor that publishes independent calibration data.

Final model and evidence note

The catalog record is retained as an active Dahua monitor in the existing Monitors category, with its existing slug and offer relationship preserved. The verified model code is DHI-LM22-L200V. The official Dahua page supports the key display and power facts; direct Bangladesh seller pages support the observed stock, price and local warranty references. No unverified market-wide price range is inferred. The observed seller listing may change after this check. The audio-output variation and the ambiguous dimension label remain disclosed so buyers can confirm them before purchase.
