| 1 | Confirm the display fits its intended use | Check screen dimensions, pixel pitch, resolution, brightness, viewing distance, refresh rate, and whether the display is intended for indoor or outdoor use. | A product specification sheet and a working demonstration using your content, where practical. | Compare specifications against the installation location and expected viewing distance. |
| 2 | Verify supplier support | Confirm support hours, contact channels, language coverage, troubleshooting process, software assistance, and availability of remote or on-site service in your region. | Written support terms, escalation contacts, response-time commitments, and a description of service coverage. | Ask who handles technical issues after delivery and whether service costs are included. |
| 3 | Read the warranty terms carefully | Check warranty duration, covered components, exclusions, claim procedure, repair or replacement options, and responsibility for shipping or labor. | A written warranty document that applies to the quoted product and destination market. | Clarify how defective modules, power supplies, and other replaceable parts are handled. |
| 4 | Check destination-market compliance | Identify the electrical safety, electromagnetic compatibility, radio, and environmental requirements that apply to the product and the country of import. | Relevant test reports or declarations, with model details that match the quoted display. Requirements vary by destination and product configuration. | Verify documents with the applicable regulator, customs broker, or qualified compliance professional before ordering. |
| 5 | Calculate the full landed cost | Include display price, packaging, freight, insurance, duties, taxes, customs clearance, local delivery, installation, and any required accessories. | An itemized quotation stating the trade term, delivery destination, currency, and which charges are excluded. | Compare suppliers using the same delivery scope and confirm who pays each cost. |
| 6 | Review spare parts and maintenance | Ask which components are replaceable, how parts are identified, whether spares are available, and what tools or technical skills routine maintenance requires. | Parts list, maintenance instructions, recommended spare-parts options, and any stated availability or lead-time terms. | Factor likely maintenance and replacement-part costs into the operating budget. |
| 7 | Confirm delivery, setup, and operating requirements | Check packed dimensions and weight, delivery schedule, installation method, power requirements, ventilation needs, content-management method, and network requirements. | Packing details, installation guide, power specifications, delivery estimate, and clear instructions for content upload or scheduling. | Confirm the site is ready and that the delivery route, electrical supply, and network access are suitable. |
