Multi-format Signals Processing

U4Pro is compatible with a variety of input signals : DVI×1, HDMI×1, VGA×2, CVBS×2, and expansion slot×1.

4k Processing Accommodating

4k signal input terminals including HDMI 1.4 and Dual Link DVI , U4Pro enables an input resolution up to 4096×2160, conveniently realizing UHD display of large LED screens!

Processor is a 4 outputs device that supports horizontal, vertical and cross splicing to reach high resolution as 15360×660 or 1536×6144.

U4pro also supports user-define output resolution , allowing users to freely change aspect ratio of resolution and refresh rate. 

Free Display of four Windows

Multi-screen Combination and Special-shaped Splicing

Super Resolution Technology

Super Resolution Zoom-in Technology can effectively eliminate edge aliasing induced from image zoom-in, thus reducing out-of-focus blur accordingly.

CrossInt Splicing Technology

The splicing unit of LED screen is often non-standard, non-uniform or different size ones, which may result in dislocation or out-sync etc. U6 adopts the CPT+FST splicing processing technology specially designed for small pixel LED displays, perfectly solving the said problem.

There’re three modes when using the local monitor & preview output of U4pro

1. Monitor the outputs, showing the same image with the Display.

2. Preview the inputs, showing 6 inputs images in the same time.

3. Monitor and preview in the same time.

Ethernet control

U4pro can be compatible with KYSTAR  management software via Ethernet or serial communication. Users can configure parameters on U4 through management software, adjust window layout, complete special effects switching, set up scheduled tasks etc.

Ethernet monitoring and preview

Via Ethernet, users can not only configure the parameters of U4pro, but achieve monitoring and preview through the KYSTAR management software in real time.

Images And Texts Overlay

U4pro is able to generate independent images and texts overlay layer. The user is allowed to overlay pictures or characters on the signal image conveniently with the KYSTAR control software . The overlaid contents can be stored in the equipment.

Users can specify the backup signal for signal source . If current signal goes wrong, the system will automatically detect and call the backup signal immediately. And if the signal returns to normal, the system will transfer back to the original signal intelligently. Building parallel system with this function, the reliability of scene can be guaranteed efficiently.

Transparency adjusting and edge feathering

In order to integrate the different layers of image well, U4pro can change the transparency of  each windows or achieve edge feathering effect.

Independent brightness control

U4pro can adjust the brightness of each inputs independently so that the user can improve the quality of the specific image without influence to the others.
