Huidu HD-A3L LED Display Player Overview
The Huidu HD-A3L is an asynchronous multimedia player for LED display content. It plays video, images, animated text, clocks, timers, weather and tables without keeping a computer connected to the screen. It is suited to commercial signage and other LED installations that need scheduled playback and remote content updates.
The HD-A3L controls up to approximately 650,000 LED pixels. Its maximum width is 8,192 pixels or its maximum height is 3,840 pixels, subject to the total pixel limit and the receiving-card configuration. Support for a 4K video window describes media decoding; it does not mean the LED canvas can contain 4K pixels.
