I. Product Introduction:
ZH-Z4D is a two-in-one high-definition video processor which developed for LED large-screen display systems. It adopts the industry's leading lossless scaling technology, supports high-definition HDMI/U-disk input and audio output and standard Gigabit Ethernet port output, and provides customers with LED screen high-definition display solutions; this product supports one-click switching between synchronous high-definition video source and asynchronous U-disk content display, which simplifies the customer operation process to the greatest extent and truly achieves the purpose of simple operation; it supports online upgrades to ensure that customers upgrade new functions from time to time.

II. Functional Features
1. Support multiple signal inputs: HDMI, USB interface;
2. Support audio and video synchronous input;
3. Supports the following output signal interfaces: LAN (RJ45) × 4 (with network port connection status indication).
4. The max resolution: 2.6 million pixels, it supports custom resolutions: max width: 8192 pixels, max height 4096 pixels; Audio audio ( PJ35) × 1;
5. Comes with U-disk playback function: U-disk content once plug and play;
6. Supports image brightness adjustment, contrast, sharpness, and chroma adjustment;
7. Support EDID configuration management: support the reading, modification and customization of EDID (Extended Display Identification Data, extended display identification data);
8. Supports Super Resolution amplification technology: video compensation processing algorithm. There is no size limit when the screen is reduced, and image details are retained, reducing the out-of-focus phenomenon that occurs after the screen is enlarged multiple times;
9. Supports black border removal/cropping function: solves the black border problem caused by input signals and performs arbitrary cropping for any signal source (still maintaining full screen status);
10. Support channel protection: protect the input and output I/O interfaces of the device to avoid the impact of over-voltage and over-current; channels are independent of each other and complementary to each other;
11. Support custom resolution;
12. Supports LED screen testing: black screen, blue screen, red screen and other display switching;
13. Support smart settings;
14. Support scene calling and saving;
15. Support online system upgrade.
