Frequently Asked Questions
What is the recommended viewing distance for P3.91?
The optimal viewing distance for P3.91 is 4 meters and beyond. At this distance, individual pixels become indistinguishable to the human eye, creating a seamless, high-definition image. For closer viewing applications, consider our P2.976 model.
How does the front and rear maintenance work?
Both front and rear panels can be opened for module replacement and maintenance. The hard-link connection supports hot-swap functionality, allowing individual modules to be replaced without powering down the entire display. This dual-access design is especially valuable for wall-mounted installations where rear access may be limited.
Do you have any MOQ limit for LED screen orders?
Low MOQ, modules or complete screen orders are all welcome. Minimum order quantity starts from 10sqm for custom projects.
What is the shipping method?
Air freight, sea freight, and rail transport are available depending on your location and delivery timeline.
How do you control production quality?
Quality control begins with incoming material inspection. All LEDs, ICs, and power supplies are pre-inspected before entering the production line. Every module and complete screen undergoes a minimum 72-hour aging test to ensure stable quality and reliable performance.
What warranty do you provide?
We provide 1-3 years warranty depending on the product. Free repair or exchange of defective parts with one-way shipping coverage during the warranty period.
