Product overview
For compact LED signage, the HD-D16 stores the display program on the controller so a computer does not need to remain connected. Wi-Fi, LAN and USB updates support local content management; optional 4G provides another route for remote access. The table follows the exact HD-D16 V0.1 document already linked to this product.

Frequently asked questions
Can the HD-D16 play an LED program offline?
Yes. Its onboard 4GB storage holds program files for asynchronous playback.
What is the documented HD-D16 control range?
The linked V0.1 specification lists 640 × 64 pixels, with a maximum width of 640 and maximum height of 128. Check these limits together rather than multiplying the separate maximum dimensions.
Does it connect directly to LED modules?
Yes. Four HUB75E ports connect the card to the LED screen modules. Check the module wiring and scan configuration.
How can I update content on the HD-D16?
Use Wi-Fi, LAN or a USB drive. The specification also lists HDPlayer and LedArt software for control.
Does 720P decoding mean it drives a 720P LED screen?
No. 720P describes video decoding. The LED screen must remain within the controller’s specified control range.
