Qtenboard: builds ເເລະ ເເລະ LCD as complete systems: industrial DID panels from 43 to 75 inches, bezel classes down to 0.88mm with a 0mm option, 500–700 cd/m² brightness, and the processors, brackets and cloud CMS that turn a set of screens into a working wall.
This guide shows how to size a Qtenboard wall: which panel size to choose, how many screens to use, what total resolution to expect and where viewers should stand. It includes ready-to-use Qtenboard configurations for 2×2, 3×3 and 4×3 layouts. Every project starts with a site and viewing assessment, and the final drawing is confirmed against the exact model and bezel class.
Qtenboard supplies three application lines on the same industrial platform. Choose the line first, then size the wall.
Built for continuous CCTV monitoring and command centers, with LG or BOE industrial panels, HDMI and DVI inputs, RS232 control and cloud CMS for remote monitoring and OTA updates.
For brand stores, entrances and window displays: 2×2, 3×3, 4×3 and custom layouts with multi-zone split-screen, plus cloud CMS, player box or USB playback.
For lecture halls, campus information centers and corporate lobbies: Full HD panels with 4500:1 contrast, built-in power supply, driver and I/O, and multi-signal split-screen functions.
Qtenboard: ເເລະ ເເລະ LCD come in 16:9 panels from 43 to 75 inches. The table gives the active image area, the Full HD pixel pitch and the distance beyond which individual pixels are no longer visible. The 46-inch active area matches the Qtenboard datasheet value of 1018.08 × 572.67 mm.
| Qtenboard panel | Active area (mm) | Pixel pitch, Full HD | Pixels invisible beyond | Typical use |
|---|---|---|---|---|
| 43" | 952 × 535 | 0.50 mm | ≈ 1.70 m | Compact walls, meeting rooms |
| 46" | 1,018 × 573 | 0.53 mm | ≈ 1.82 m | Close-range walls, campus and small control rooms |
| 49" | 1,085 × 610 | 0.56 mm | ≈ 1.94 m | Retail and corporate displays |
| 55" | 1,218 × 685 | 0.63 mm | ≈ 2.18 m | Control rooms, lobbies, brand stores |
| 65" | 1,439 × 809 | 0.75 mm | ≈ 2.58 m | Large lobbies, exhibition halls, operations rooms |
| 75" | 1,660 × 934 | 0.86 mm | ≈ 2.97 m | Large venues with long viewing distances |
Dimensions are calculated from the nominal diagonal. Some modules have a slightly smaller true diagonal, so always take final dimensions from the model datasheet and mounting drawing. To compare larger and smaller panels for monitoring rooms, see our analysis of 55-inch vs 65-inch LCD video wall for control rooms.

Use the matrix to shortlist a Qtenboard configuration. Image sizes exclude seams. Total pixels assume Full HD panels; Qtenboard offers 4K options on selected models, so confirm by model. The viewing band is the planning range for the whole wall, from about 1.07 to 1.45 times the wall width.
| ໂປຣເເກຣມ | Qtenboard panel | Image size (m) | Total pixels (Full HD) | Viewing band |
|---|---|---|---|---|
| 2×2 (4 panels) | 46" | 2.04 × 1.15 | 3840 × 2160 | 2.2 – 3.0 m |
| 2×2 | 55" | 2.44 × 1.37 | 2.6 – 3.5 m | |
| 2×2 | 65" | 2.88 × 1.62 | 3.1 – 4.2 m | |
| 3×3 (9 panels) | 46" | 3.06 × 1.72 | 5760 × 3240 | 3.3 – 4.4 m |
| 3×3 | 55" | 3.65 × 2.05 | 3.9 – 5.3 m | |
| 3×3 | 65" | 4.32 × 2.43 | 4.6 – 6.3 m | |

Not sure whether a 2×2 or a 3×3 suits the room? Our guide to comparing 2x2 vs 3x3 video wall configurations covers space, content and display needs.
Three starting configurations for the most common Qtenboard projects. Each combines the wall size, resolution and viewing distance from the matrix with the Qtenboard panel and system options that fit the job.
A four-panel brand wall at the store entrance, playing campaign film and product loops for customers who approach from about 3 m.
A nine-panel wall for operators seated 4–5 m away, showing maps, dashboards and camera feeds around the clock.
A twelve-panel wide canvas for large lobbies and event spaces, viewed by visitors standing 6 to 8 m away.
Tell our engineers your site dimensions, viewing distance and application, and get a confirmed drawing with the exact model, bezel class and system list.
ຕິດຕໍ່Qtenboard engineers use three quick rules when drafting a layout. Each is a short calculation you can reproduce for your own room.
1 · Size
ເກີດຂໍ້ຜິດພາດ
Seams change the size very little: even 3.5mm seams add under 10 mm to a 3×3 wall.
2 · Pixels
Total resolution
A 3×3 Qtenboard wall of Full HD panels is 5760 × 3240; a 2×2 is a 3840 × 2160 canvas.
3 · Distance
Viewing band
A planning band, to be adjusted to the client's ergonomic standard. Also keep the nearest viewer beyond the pixel-invisible distance in the panel table.
Characters should be at least about 4.7 mm tall per metre of viewing distance, and 5.8 mm for comfortable reading. At 4 m that is 19 to 23 mm, roughly 29 to 37 pixels for a capital letter on a 55-inch Full HD Qtenboard wall. 4K panels add detail and window capacity, not smaller readable text.
A video wall is more than its screens. Qtenboard supplies the signal, control, mounting and management components from the same factory, so the layout, signal path and structure are planned together.
| Qtenboard component | Role in the wall |
|---|---|
| Video wall image processor | Splitting, scaling and bezel compensation across the whole canvas |
| HDMI matrix switcher | Routes multiple sources to any panel or window |
| Signal distributor | Distributes one source to several panels |
| Network video decoder | Decodes IP camera streams for security walls |
| Hydraulic mount stand | Precise alignment and easier panel service |
| Network cabinet | Houses processors, switchers and signal equipment |
| Media playback box | Local playback for advertising walls, independent of the network |
| Infrared touch frame | Optional touch upgrade for interactive walls |
| Wireless casting device | Screen sharing for meeting and showroom use |
Because Qtenboard publishes unit weight and power, structure and electrical loads can be planned before the order. Using the 46-inch datasheet values (about 15 kg and up to 180 W per unit), the panel totals are:
| ໂປຣເເກຣມ | Panels | Panel weight | Operating power (maximum) | Standby power (maximum) |
|---|---|---|---|---|
| 2×2 | 4 | ≈ 60 kg | ≤ 720 W | ≤ 12 W |
| 3×3 | 9 | ≈ 135 kg | ≤ 1,620 W | ≤ 27 W |
| 4×3 | 12 | ≈ 180 kg | ≤ 2,160 W | ≤ 36 W |
Totals exclude brackets, cabinets and processors; take other sizes from the model datasheet. Each unit is 70.1 mm deep and runs on 100–240V. Once the numbers are confirmed, our guide on how to build a video wall: best practices for commercial and control room LCD video wall deployment covers installation and commissioning.
Qtenboard's cloud-based CMS gives integrators and brand teams remote control over single walls or whole networks.
Qtenboard manufactures its LCD video walls in its own 330,000 m² base, with daily capacity above 200 units. Each unit completes a 48-hour aging test and colour calibration to keep brightness uniform across the wall, under ISO9001 with CE, FCC and RoHS compliance. Qtenboard systems are sold in more than 100 countries.
Your brand logo on the panel, packaging and boot screen, on Qtenboard's standard hardware platform.
Custom bezel, brightness, interfaces and software functions matched to your project.
Complete knocked-down kits with panels, power board, controller and housing for local assembly overseas.
Semi-finished assembled units that reduce your local production workload for faster delivery.
Qtenboard: ເເລະ ເເລະ LCD are available from 43 to 75 inches, with splicing gap classes of 8mm, 3.5mm, 1.8mm, 1.7mm and 0.88mm, plus a 0mm option. Availability of each bezel class can vary by panel size, so confirm it for your project.
Each unit is Full HD (1920 × 1080) as standard, so a 3×3 wall is 5760 × 3240 pixels and a 2×2 wall is a 3840 × 2160 canvas. 4K options are available on selected models.
As a planning band, about 3.9 to 5.3 m. Individual pixels on a 55-inch Full HD panel become invisible beyond roughly 2.2 m, and the smallest text should be sized for the actual viewing distance.
Choose 0.88mm when maps or dashboards span several panels, and 3.5mm when each panel shows its own camera feed. In both cases the industrial DID panels are designed for 24/7 operation.
Yes. Qtenboard supplies video wall processors, HDMI matrix switchers, signal distributors, network video decoders, hydraulic mount stands and network cabinets together with the panels.
Yes. Qtenboard uses industrial-grade DID panels with a service life of about 60,000 hours, designed for continuous operation in CCTV monitoring and command centers.
Yes. Qtenboard offers OEM branding, ODM customisation, and CKD or SKD kits for local assembly, so integrators and distributors can deliver the wall under their own brand.
Through the Qtenboard cloud CMS: remote source switching, layout scheduling, device status tracking, batch control and OTA firmware updates, so fewer site visits are needed.
