COMMON QUESTIONS
LED display FAQ
How do I choose pixel pitch?+
Start with viewing distance and the detail required. A smaller pitch supports closer viewing but increases system cost and data load.
How bright should an outdoor screen be?+
Ambient light and screen orientation matter. Outdoor configurations commonly range from about 4,500 to 10,000 nits; automatic brightness control is recommended.
Front or rear maintenance?+
Front service suits wall-mounted screens with no rear access. Rear service can simplify fixed structures where a maintenance corridor is available.
What information is needed for a quotation?+
Screen width and height, indoor/outdoor use, viewing distance, installation method, target date, delivery country and available site photos.
Why does refresh rate matter?+
Higher refresh rates reduce scan artifacts on camera and improve performance for broadcast, stage and fast-moving content.
How many spare parts should be ordered?+
The recommended spare ratio depends on project size and service conditions. Modules, receiving cards, power supplies and cables should match the delivered batch.
