Dahua DHI-LM22-A201YFS 21.45-inch IPS Full HD 100Hz Monitor

Exact A201YFS model identity

The Dahua DHI-LM22-A201YFS is a 21.45-inch Full HD IPS monitor in Dahua’s Commercial Series. Dahua’s Bangladesh product page identifies the full model string DHI-LM22-A201YFS, while the corresponding datasheet uses the same model code. Preserve the final letters: they distinguish this product from nearby displays whose specifications are not interchangeable. Bangladesh retailers assign their own catalog references, including Star Tech product code 41306 and Ryans item ID 08.02.776.34. Those are store identifiers, not Dahua part numbers and not BiponiBD SKU values. The existing BiponiBD URL slug stays in place; the product title and specification fields carry the exact model identity.

21.45-inch IPS Full HD screen

The monitor has a flat IPS panel with a 21.45-inch viewable diagonal, 1920 × 1080 native resolution and a 16:9 aspect ratio. Dahua specifies an LED backlight and 178-degree horizontal and vertical viewing angles. The IPS format helps maintain color and brightness from wider viewing positions than a narrow-angle panel. Full HD resolution is a practical fit for office software, browser tabs, point-of-sale interfaces, study material, video and surveillance dashboards. Screen size refers to the diagonal display area, while the casing and stand require additional desk space. The panel is described by Dahua as a light, cost-effective plastic housing with a plastic base.

Brightness, contrast and color support

Dahua lists maximum brightness of 250 cd/m², a 1000:1 contrast ratio and 16.7 million colors using 8-bit color support. These values describe the published display specification; the manufacturer does not provide an sRGB or NTSC gamut percentage on the official product sheet. For that reason, the listing should not assign a color-coverage percentage based on another IPS model or generic category copy. The monitor is intended for general productivity and viewing rather than a documented wide-gamut or factory-calibrated workflow. Its 178°/178° viewing angles complement the IPS panel for desk sharing and viewing from off-center positions.

Maximum 100Hz refresh and connection choice

Dahua lists a maximum refresh rate of 100Hz and one HDMI plus one VGA input. For a computer capable of outputting Full HD at 100Hz, HDMI is the sensible first connection to use. The official product specification does not publish a detailed per-input timing table, so the exact VGA ceiling should be confirmed against the source device and supported display mode rather than presented as a guaranteed Dahua maximum. Analog VGA timing is commonly lower than the digital HDMI mode. The computer’s graphics hardware and operating-system settings determine which refresh options appear. A 100Hz monitor refreshes the image up to 100 times per second; it does not guarantee that every application or game will render 100 frames per second.

Response time: use the official 10ms maximum

The official Dahua page and datasheet specify response time as 10ms (Max). Some third-party pages or related-model references describe 5ms Overdrive, but the cited official DHI-LM22-A201YFS document does not include that separate 5ms mode. The listing therefore uses Dahua’s published 10ms maximum and does not promise a 1ms MPRT or GtG result. A response-time number alone does not determine perceived motion clarity; refresh rate, source frame rate, pixel transitions, overdrive settings and content all matter. Buyers looking for a specifically advertised 1ms MPRT mode should compare a different model whose own specification states that feature.

The S suffix adds dual 1W speakers

This A201YFS version includes two built-in 1W speakers, as listed by Dahua. That makes it convenient for system alerts, online lessons, basic video calls and casual playback without a separate pair of desktop speakers. HDMI can carry digital audio from a compatible computer into the display. The VGA connection is video-only, so a separate audio cable or the computer’s own audio output is needed when using VGA. The speakers are compact utility speakers; users who want fuller music or movie sound may prefer external speakers or headphones. The non-S DHI-LM22-A201YF is a closely named model and should not be assumed to have this audio package.

Anti-blue-light design and unlisted comfort features

Dahua describes an anti-blue-light design for this monitor. Its official source does not publish a separate flicker-free certification or adaptive-sync specification for the exact A201YFS, so those claims are not included. Anti-blue-light features can help users adjust the display for long reading or office sessions, but they do not guarantee that eyes will not become tired. Room lighting, viewing distance, text size and regular breaks still matter. For work that depends on color judgment, users should check whether a selected comfort mode changes the screen’s appearance and turn it off while evaluating color.

HDMI, VGA and audio behavior

The rear connection list includes one HDMI input and one VGA input. HDMI supports digital video and can carry audio to the integrated speakers. VGA supports older computers and devices that provide analog output, but does not carry audio through the cable. The official product page lists output as not available and does not list DisplayPort or USB-C. Buyers should check which output their computer provides and select the correct cable before ordering. The HDMI and VGA connectors support different generations of equipment; having both does not mean both can be used simultaneously as one combined display input.

Narrow bezel and desk footprint

Dahua lists upper, left and right bezel widths of 3.3mm and a lower bezel of 15.2mm. This three-side narrow-bezel design helps keep the frame visually compact and can reduce the apparent gap in side-by-side installations. The official dimensions without the stand are 492.7 × 284.0 × 41.2mm (W × H × D). Dahua also lists the shipping package at 598 × 99 × 366mm. Keep those measurements separate: the package dimensions describe the carton, and the published assembled-display dimensions exclude the stand. A precise overall desk footprint with the stand is not provided in the official sheet.

Tilt stand and 75 × 75mm VESA

The supplied plastic base and stand support tilt according to Dahua’s product description; the official online spec table does not show a numeric tilt range or list height, swivel or pivot adjustment. The monitor supports a 75 × 75mm VESA mount. This is smaller than the commonly assumed 100 × 100mm pattern, so check the bracket before buying. A universal arm often includes both hole patterns, but compatibility should be confirmed from its manual. The monitor head weighs 2.05kg net, which makes it suitable for many compact arms whose load range includes the display. Mount hardware and screws should match the specific bracket and monitor.

External DC power and consumption

The DHI-LM22-A201YFS uses an external DC 12V power supply. Dahua specifies 22W standard consumption and standby power at or below 0.5W. The official standard accessory list includes an adapter, HDMI cable and base. Keep the adapter accessible and use the correct rated supply; do not substitute a generic unit unless its voltage, polarity and current rating match the manufacturer requirements. The datasheet lists a net weight of 2.05kg and gross packaged weight of 2.86kg. These figures help estimate handling and mounting, while package measurements help plan transport and storage.

Bangladesh warranty and market context

Bangladesh retailer listings show a three-year warranty for this model and current or recently observed market prices around ৳9,400–৳10,200, depending on seller and offer. These are competitor references, not a BiponiBD price quotation or a promise of stock. Retailers can change prices and terms. The manufacturer datasheet does not specify a Bangladesh service provider or separate coverage for the power adapter. Confirm the exact BiponiBD unit’s warranty provider, claim route, adapter coverage, invoice wording and return conditions before relying on them. Product page price and availability should reflect BiponiBD’s own verified live offer data.

Distinguish A201YFS from Dahua sibling models

Dahua’s monitor range includes similar-looking names that differ by panel, color, speaker package, input ports and refresh rate. The DHI-LM22-A201YFS is the black 21.45-inch IPS, 100Hz model with two 1W speakers. DHI-LM22-A201YF is a non-S sibling without guaranteed speakers; DHI-LM22-A201YFW is a white variant. DHI-LM22-A211Y is a different 120Hz model whose advertised response options include 1ms MPRT; those figures do not belong to A201YFS. DHI-LM22-A200Y/A220 family options use VA panel specifications. Another Dahua C201P model can offer DisplayPort instead of VGA. Always match the full product code and inspect the rear label before combining catalog content or imagery.

Category fit and search-ready product information

The existing Monitors category is the right primary category. Useful filters include Dahua, 21.45-inch, IPS, Full HD, 100Hz and built-in speakers. A precise product title, complete specifications, substantive long description and focused FAQs help people find the exact A201YFS and understand how its speaker-equipped “S” version differs from A201YF. Keep the existing canonical slug. Do not insert retailer item codes as MPN or SKU, do not copy A211Y’s 1ms MPRT claims, and do not add unsupported gamut or adaptive-sync features. Competitor prices and stock status should remain research context; only BiponiBD’s live offer can populate its selling price and availability.
