A practical guide for distributors, system integrators, and procurement teams evaluating LCD video wall quality processes
Multi-panel video walls amplify the impact of any single panel issue:
The following table outlines the 8 core inspection areas that buyers should expect from a commercial LCD video wall supplier. Qtenboard performs all 8 points with documented records for every shipment.
| Inspection Area | What Should Be Checked | Project Risk Reduced |
|---|---|---|
| Panel appearance | Surface condition, frame condition, visible damage, scratches | Avoids cosmetic defects discovered after installation |
| Display function | Power-on, input detection (HDMI/DP), image output, OSD menu | Reduces basic commissioning failures on site |
| Uniformity review | Major brightness or color inconsistency across the batch | Helps ensure whole-wall visual consistency |
| Bezel and dimensions | Panel dimensions and bezel specification (±0.5mm tolerance) | Supports accurate layout and alignment planning |
| Liidesed | HDMI, DP, control ports, power connectors, USB ports | Prevents site connection problems |
| Mounting points | Mounting-hole pattern, VESA or custom configuration | Reduces bracket mismatch risk during installation |
| Tarvikud | Cables, screws, mounts, controllers, remote, labels | Avoids missing parts at the project site |
| Pakendamine | Protective materials, cartons, palletization, shipping marks | Reduces shipping damage and warehouse errors |
For multi-panel video walls, batch consistency is more important than individual panel performance. Panels from different production batches can have subtle variations in color temperature, brightness, and bezel dimensions.
What buyers should understand about batch consistency:
Clear responsibility boundaries prevent disputes and ensure smooth project handover. The table below defines factory responsibilities vs. buyer/integrator responsibilities at each project stage.
| Stage | Factory or Supplier Responsibility | Integrator or Buyer Responsibility |
|---|---|---|
| Before shipment | Confirm model, quantity, visible condition, function, packaging, accessory list | Confirm approved configuration and inspection scope; request pre-shipment documentation |
| During shipment | Provide packing list, shipment marks, product identification, and shipping documents | Inspect goods on arrival and report damage promptly (within 3-5 days) |
| Before installation | Provide manuals, installation drawings, and configuration information | Verify site conditions, power supply, mounting plans, and handling procedures |
| Site commissioning | Support according to agreed scope (may include remote guidance) | Test complete system, signal switching, panel alignment, and client acceptance |
For vendor due diligence and project documentation, request these 9 documents from your LCD video wall supplier:
This is an illustrative project scenario, not a named customer case study. An AV integrator is delivering a 3×3 LCD video wall (9 panels) for a retail media display. The project has a tight 45-day installation window from order to client handover.
The integrator received all 9 panels with matching brackets, complete accessories, and batch-consistent color calibration. Installation was completed in 12 days without any field modifications or missing parts. The client accepted the wall on the scheduled date.
For project-specific quality planning, contact Qtenboard with your panel requirements, layout, and inspection needs.
Qtenboard performs an 8-point inspection including appearance, function, uniformity, bezel dimensions, interface testing, mounting-point verification, accessory check, and packaging review. Each panel is powered on and tested with standard signal patterns. Inspection records are archived by serial number.
Yes. Qtenboard provides pre-shipment photos and videos upon request. For large projects, we can also accommodate third-party inspection arrangements at the buyer's expense. Contact us to discuss your specific inspection requirements.
Qtenboard reserves the entire production batch for your project quantity. Panels within the same batch are calibrated together using the same reference settings, with a target color difference of ΔE < 3. Batch certificates are available upon request.
Yes. Qtenboard can provide photos of the packed shipment, video of the functional test, and a detailed packing list with serial numbers before loading. This gives you documented evidence to compare against the delivered goods.
Check the packaging condition first — note any damage on the delivery receipt. Then verify model numbers, quantity, and serial numbers against the packing list. Finally, inspect panel surfaces for scratches or damage before installation. Report any issues within 3-5 days of delivery.
Yes. Qtenboard can reserve spare panels or components for your project, ensuring replacement units are available when needed without production delays. This is particularly important for multi-panel video walls where panel matching is critical.
Report any shipping damage to the carrier immediately and photograph the packaging and panel condition. Contact Qtenboard within 3-5 days of delivery with photos and a description. We will work with you to assess the issue and arrange replacement or repair according to the warranty terms.
Qtenboard provides datasheets, packing lists with serial numbers, installation guides, bracket compatibility information, controller connection diagrams, warranty policies, and pre-shipment inspection records — all available in English and other languages for international projects.
Whether you're a distributor conducting supplier due diligence, an integrator planning a multi-panel installation, or a procurement team evaluating long-term partners — Qtenboard provides documented quality processes, batch-consistent panels, and project-specific inspection support.
