Customer question: Are indoor fine-pitch used cabinets more sensitive during installation?
English explanation
Fine-pitch indoor displays are often viewed close to the screen, so flatness, seam alignment, uniformity and low-gray performance become very visible. Start with a rigid, level wall or frame and confirm that the finished opening matches the cabinet layout. Do not force a cabinet into an opening that is too small or use excessive pressure to hide a structural error. Number the cabinets and keep their orientation consistent. Check alignment pins, locks, module surfaces and rear connections before closing the wall. Plan front or rear service access, power-supply replacement, receiver access and ventilation. Indoor conditions still require protection from condensation, roof leaks, cleaning liquid, sprinkler water and blocked air-conditioning discharge. Commission with grid, fine text, gray gradients, white, RGB and skin-tone content. Inspect from the customer’s closest normal viewing position and from the main audience position. If cabinets come from different batches, compare uniformity before final installation. A global brightness or colour adjustment should not be used to hide one local module or receiver fault. Keep the original configuration and calibration files. Fine-pitch screens are particularly sensitive to wrong scan mode, data group or module mapping. Complete a stable operating test before the final frame or decorative cover is installed.
Service boundary
Wall strength, structure, electrical work and building coordination require qualified professionals; the LED supplier should confirm product and maintenance requirements. —
