Dahua DHI-LM34-E330CA overview
The Dahua DHI-LM34-E330CA is a 34-inch ultrawide curved gaming monitor with a 21:9 VA panel and native WQHD resolution of 3440 × 1440. Dahua lists a 200Hz maximum refresh rate, 1ms MPRT motion-response mode, 1500R curvature, Adaptive-Sync and HDR10. This combination is aimed at players and desktop users who want a wide field of view, smooth motion and extra horizontal space for games, editing timelines or side-by-side windows. Dahua’s current exact-model page lists 300 cd/m² typical brightness, 3500:1 contrast, 8-bit plus FRC display color, 85% NTSC gamut, two HDMI 2.0 inputs and two DisplayPort 1.4 inputs. The supplied stand provides tilt, swivel and 100mm height adjustment, and the display supports a 100 × 100mm VESA mount. The current catalog name already identifies the exact model and core use, so this update standardizes inch and Hz formatting, replaces the incorrect Others brand with the active Dahua brand, and removes extra text from model and manufacturer part number. Existing slug, Monitors category, Active status, variant SKU, ৳47,000 MSRP, logistics and three-year catalog warranty remain as recorded.
Ultrawide WQHD workspace
The 3440 × 1440 resolution spreads 4,953,600 pixels across a 21:9 image. Compared with a conventional 16:9 display, the wider shape can show more of a game environment or more columns on a desktop. It can also place two windows side by side without requiring a second monitor, depending on application layout and operating-system scaling. Dahua lists a 34-inch screen, 797.22 × 333.72mm viewing area, 0.2318mm pixel pitch and 109.7 pixels per inch. The VA panel has a 178-degree horizontal and vertical viewing angle specification. The display uses ELED backlighting and a matte surface treatment listed as haze 25%, 3H. A curved screen is measured at 1500R, which wraps the wide panel toward the viewer. Screen size and perceived curve are subjective, so viewing distance and desk depth matter. The monitor has a 16:9-compatible source mode and supports picture-in-picture and picture-by-picture according to the family manual; the main workspace remains 21:9 when using its native resolution.
200Hz motion and Adaptive-Sync
Dahua specifies a maximum 200Hz refresh rate. The published connection table allows 3440 × 1440 at up to 200Hz over either DisplayPort 1.4 input, while the HDMI 2.0 inputs are listed up to 100Hz at the same resolution. To reach the 200Hz mode, the graphics card, cable, driver and selected display mode must all support that signal. A high refresh rate can make pointer movement, camera pans and compatible games appear smoother when the source device supplies enough frames. The 1ms response claim is MPRT, which is a motion-picture-response measure and should not be confused with an always-on 1ms grey-to-grey panel response. The E330CA manual lists Adaptive-Sync and selectable response-time controls. Motion results depend on game frame rate, overdrive setting, synchronization mode and the particular scene. Buyers should plan to connect a gaming PC through DisplayPort when seeking the full 200Hz mode; a console connected over HDMI will use a lower maximum refresh supported by the source and HDMI input.
Contrast, color and HDR10
Dahua’s current model page lists 300 cd/m² typical brightness, 3500:1 contrast and HDR10 support. The 2025 datasheet describes a wide color gamut as 120% sRGB, 85% NTSC, 85% DCI-P3 and 85% Adobe RGB; its technical table lists 85% NTSC and 8-bit plus FRC color. Color-gamut percentages use different reference spaces and should not be compared as if they were the same scale. VA technology and the specified contrast can make dark scenes look more distinct than on many standard IPS displays, although actual black level and uniformity vary by unit and room. HDR10 support indicates signal compatibility, not a named VESA DisplayHDR certification. The manufacturer’s stated brightness and gamut should guide expectations for HDR playback. Users can select picture modes, adjust RGB and gamma, enable dynamic contrast and use game profiles in the on-screen menu. For color-critical delivery, verify the chosen color mode and use a calibration workflow instead of relying on gamut marketing figures alone.
Ports and source compatibility
The exact-model Dahua product page and E330CA user manual show two HDMI 2.0 inputs, two DisplayPort 1.4 inputs, one audio output and an external DC power input. Dahua lists the HDMI inputs at 3440 × 1440 up to 100Hz and DisplayPort up to 200Hz. This is a conflict with several Bangladesh retailer pages that summarize a single HDMI and a single DisplayPort. The catalog technical values follow Dahua’s exact-model documentation; check the actual regional unit and port panel with the seller before buying or selecting a cable. The monitor has no USB hub or USB-C connection listed in the manufacturer specifications. Its audio output is for headphones or external speakers; built-in speakers are not listed. Picture-in-Picture and Picture-by-Picture can show more than one connected source, subject to input compatibility and OSD settings. The menu lets the user choose among DP1, DP2, HDMI1 and HDMI2. Cable quality, graphics output, operating-system driver and display mode all affect available resolution and refresh settings.
Stand, mounting and physical fit
The current Dahua product page lists a tilt range of −5° to +15°, left-right rotation of −35° to +35° and 100mm of height adjustment. It supports a 100 × 100mm VESA mount. Catalog data previously showed a 75 × 75mm mount and ±40° swivel; those values conflict with the exact-model Dahua specification and are corrected here. Dahua lists product dimensions without the base as 810.4 × 361.5 × 132.1mm and net weight as 7.3kg. Package dimensions are 1124 × 468 × 193mm and gross weight is 10.2kg. The ultrawide panel needs sufficient desk width and depth, and a monitor arm must support the weight and VESA pattern. The catalog’s dimension attribute is retained as a field but clarified as without base. The current product page lists a power adapter, wall-mount bracket, DisplayPort cable and user documentation among accessories; exact in-box components can vary by market. Confirm the stand and cable bundle with the local seller before installation.
Power and operating conditions
Dahua specifies an external power adapter rated at 19V DC, 3.42A. The current model page lists 29W basic, 47W typical and up to 70W maximum consumption, with standby below 0.5W. The official product page lists an operating temperature range of 0°C to +40°C and operating humidity from 10% to 85% relative humidity. Provide adequate airflow around the rear vents and use the supplied adapter with a grounded power source. Power use changes with brightness, refresh setting, enabled modes and connected signal. A 200Hz desktop mode may require a compatible graphics output and can increase graphics workload compared with lower refresh settings. Dahua’s five-button control system operates the on-screen display; the manual documents game profiles, Adaptive-Sync, response-time options, MPRT, PIP/PBP and input selection. Product dimensions, accessories and exact power labeling should be checked on the local unit and packaging, particularly when purchasing through a seller outside the authorized distribution channel.
Bangladesh price and warranty
Bangladesh listings checked for this model showed seller prices from ৳46,500 to ৳48,400: Star Tech and Techland displayed ৳46,500, Ryans ৳47,000, Skyland ৳48,400 and CSI ৳48,000 when reviewed. Offers and stock can change, so this range is a dated market comparison rather than a BiponiBD store offer. The catalog variant MSRP remains ৳47,000. Star Tech, Ryans and Techland pages list a three-year warranty, consistent with the catalog warranty field; confirm the local warranty provider, claim process, serial number coverage and invoice requirements before ordering. Ask the seller to confirm that the offered unit is the DHI-LM34-E330CA, the actual number of HDMI and DisplayPort inputs on that regional unit, the cable bundle, current price, stock, return window and delivery charge. Dahua’s exact-model documentation specifies two HDMI 2.0 and two DP 1.4 inputs, while local retailer quick views sometimes show only one of each. Checking the unit’s rear panel or a written specification from the seller can resolve that regional listing difference.
Who should consider the E330CA
The DHI-LM34-E330CA may suit PC gamers who want 3440 × 1440 ultrawide resolution and a 200Hz DisplayPort mode, as well as users who prefer a wide canvas for editing, productivity or immersive media. The 1500R curve, VA contrast specification and 21:9 aspect ratio are central to its viewing experience. It can support multiple signal sources through the documented HDMI and DisplayPort inputs, while the OSD offers PIP/PBP and game-oriented controls. Buyers should ensure the graphics card can drive WQHD at the desired refresh rate and account for the wide monitor’s desk footprint. It is not a USB-C docking display and no built-in speakers are listed. Anyone requiring a guaranteed local port configuration should ask the seller to verify the rear-panel layout because Bangladesh listings do not all reproduce Dahua’s port count accurately. For HDR-sensitive work, consider that the monitor lists HDR10 but does not list a VESA DisplayHDR certification.
