  4. Operating Environment

      1. Computer configurations

        • CPU Frequency >= 2.0GHZ;

        • Host Memory >= 1G;

        • Graphic card with DVI interface: Memory 512MB.

          Computer configuration can be adjusted according to the actual situation. Adjustment mainly aims at total pixels of LED display, complex playing program and whether playing HD video or not. Please note that the PC’s graphic resolution should be equal to or more than LED display’s.

      2. USB driver installation

        There are two methods for installation USB driver.

        • Check ‘USB Drive For Sending Card’ when install the LEDVISION, as you can see in following picture.



        • Open the CD-ROM, find the file name of "USB driver for sending card" and

          double click it to install.

      3. Graphics Card Settings

        Select duplicate or extend in graphics card mode, and their difference is that led display show the contents consistent with computer in duplicate mode, while in extend mode show only the window you want to display. (As shown in Fig.4-2)



        How to change the mode, there have different ways in different computer. For example, WIN 7/8 system and NVIDIA graphics cards, please read the following settings ways.

        • The first way: Hold down the WIN and P keys at once, and select the mode as you want in the pop-up window



        • The second way: Right-click and select “screen resolution” to enter the page of “modify the display appearance”; if your graphics card is not NVIDIA and cannot find the setting interface please refer to the description of the graphics card.





  5. Parameter Configuration

First of all, please make sure the software is in Classic Mode before setting.

Click the “Setting” > “Software Setting” to enter the Software Management window (As shown in Fig.5-1), change the mode by using password: 168.



    1. Hardware Connection Check

      Please make sure that the hardware connection correct and software in Classic Mode before setting.

      1. Detect Sender Cards

        Run software, click the “Control” > “Screen Management” to enter the Screen Management window, the Sender Mode select “By Sender Card”, Click “Detect Sender Cards”, the sender cards information will show in the interface, (as shown in Fig.5-2 ) Please check the hardware connection if cannot detect sender cards.

      2. Detect Receiver Cards

Select network port and click “Detect Receiver Cards”, the software will automatic acquisition the Receiver (Receiving card) quantity for each network port of the sending card. Please check cable if the numbers of receiver card are inconsistent with actual. (As shown in Fig.5-3)

    1. Setting Parameter

      1. Sender Card Setting

        Software offers a variety of common resolution to choose and it also can be set up custom. It should be note that the port maximum load capacity is 655360 pixels and the starting position consistent with the actual.

        Click “Send” to save the parameter in receiving cards.

      2. High Setting

        In Screen Management interface, click “High Setting” to enter the High Setting-Send Card interface, the parameter can be set up according to your demand.



        In general, users only need to set up the sender card resolution and network port control area in so many parameters.

        • Sender Card Resolution: Send card resolution must be consistent with the graphics card or video processor output.

        • Network Date Types: The software default is “Standard Frame”; please consult professional and technical personnel if you want changing.

        • Adjust Brightness Based on Multi-function: Check it if you need multifunction’s light sensor automatically adjusts the LED screen’s brightness.

        • DVI Information: The parameters automatically collect by the software from the sender card.

        • Could By Pass Switch: When the gigabit switches as transfer equipment, then required checking this

        • Output Frame Rate: the software default is “Every Frame”, please consult professional and technical personnel if you want change to “Every Other Frame”

        • Forbid output video and audio when no signal: After check this item, the LED display will turn black and no sound output when no video signal input.

      3. Receiver card parameters setting

Click “Configure Select One...” to enter LED setting interface by using password 168.



Need to debug of common parameters

      1. Connection Parameters (Look From Front)


        In Classic Mode, LED screen need set up the Receiver (Receiving card) connection relationship for each network port of the sending card.

        1. Receiver Lay out Setting

          Set how many Receiver (Receiving card) one port managers in Row Count and Col Count (3*3 as an example), how many pixels one Receiver (Receiving card) manages in Width and Height (64*64 as an example), in the software interface right you will see led display mapping area (Viewing from the front of led display). (As shown in Fig.5-7)



        2. Receiver Card Parameters Setting

          Configuration Receiver (Receiving Card) connection pattern for each port individually if more than one port are used. There are two methods to set up.

          Note: Set up connection Receiver (Receiving Card) must be based on fact.

          • Use Mouse Select One By One

            Based on the actual connection of the Ethernet cable, click the Receiver (Receiving card) one by one until the last one for this network port loads, connection lines will show in the display mapping area (Viewing from the front of led display) (As shown in 5-8)




          • Connection Pattern

Select the connection pattern based on fact, and then the connection line will show Receiver (Receiving card) in the display mapping area. (As shown in 5-9)



If some Receiver (Receiving card) manage different quantity of pixels from others, specific Receiver (Receiving card) Size in Width and Height can be set individually.

  1. Save to Receiver Cards & Save to Sender Cards


The first step: Click “Save to Sender Cards” > select port, then send the parameter to sender card

The second step: Click “Save to Receiver Cards” > select port, to send the parameter to receiver cards of this port load, at this moment, this port load all cabinets should display normally (the picture between cabinets is not continuous but also as normal)

The third step: Set up the next port load receiving cards parameter and connection type.

Please contact display manufacturer of engineering and technical personnel if display abnormally.
