Direct module connection or receiving-card cascade
Choose the connection method before sizing the screen. Direct loading and receiving-card cascade loading have different limits. Very wide layouts also require loading reduction under the documented width condition; confirm the workable configuration before ordering a controller.
Frequently asked questions
Can one C16L board directly load 650,000 pixels?
The linked specification lists direct single-card loading of 200,000 pixels. The 650,000-pixel value applies to a receiving-card cascade.
How many HUB75E interfaces are on the board?
There are 12 onboard HUB75E interfaces. The Gigabit output provides a separate connection to HD-R receiving cards.
What is the maximum width?
The listed maximum width is 8192 pixels, with loading reduction when width exceeds 1920 pixels. Confirm the screen layout and resulting load before installation.
Can it play programs without a continuously connected computer?
Yes. It supports asynchronous multimedia playback, with programs updated through Wi-Fi, Ethernet or USB.
Does it support cloud management and cellular networking?
It supports XiaoHui Cloud remote management. The 4G networking function is optional.
