HD-H4K frequently asked questions
Does HD-H4K connect directly to LED receiving cards?
The H4K provides an HDMI 2.0 output for a monitor or LED video processor. Its 100 Mbps Ethernet port is for program publishing and control, not a specified LED receiving-card output. Use a compatible sending/controller system for an LED wall.
Can I control the H4K through Wi-Fi?
Yes. Dual-band 2.4 GHz and 5 GHz Wi-Fi is standard, with AP/Station mode switching and the Screen Control app described in the specification. Wi-Fi control is separate from the optional wireless screen-casting function.
Are wireless screen casting and mobile networking included?
Wireless casting is optional. The PDF identifies an optional 4G module at the SIM slot and also mentions optional 4G/5G in the feature list. Confirm the exact network module, regional support and casting configuration supplied.
Does the 16,384-pixel width mean 16K video output?
No such output timing is specified. The document lists a maximum canvas width of 16,384 or height of 4,096 and 4K HDMI output support. Confirm the actual output timing, canvas mapping and processor compatibility; decoding limits are also separate.
What content and remote-management workflows are supported?
The specification lists video, images, GIF, text, Office documents, tables, clocks, weather, QR codes and environmental data, plus third-party APK installation. Programs can be updated locally, and XiaoHui Cloud access supports remote cluster management. Check required apps, sensors and network access for the chosen content.
