5.2 LED Screen Setting
Click [LED Screen Settings] to enter the LED Screen Setting interface, and set up
“Sending Device”, “Screen Parameters”, “Connection Parameters”.

7
5.2.1 Sending Device Setting
[Select Sending Device] for [Sender], and detect senders. Sending Device Setting
includes 6 parts: Output, Control Area, EDID, Network, Other, Detect Receivers.
1. Output
①Signal Source
When the input signal source of Z4 is normal, the upper right of the software interface will
display the input signal information auto acquired via the software. Users can select specific signal
source (HDMI/DVI/SDI1/SDI2/DP) according to needs in [Main]; If PIP mode has been open, users
can also select specific signal source (HDMI/DVI/SDI1/SDI2/DP) in [PIP]. At the moment, the image
of selected signal source will display in the Image View Area on the left of the software interface.
Note: Main and PIP can’t select the same source. When PIP1 and PIP2 exist in output
mode at the same time, PIP1 and PIP2 can select the same source.
②PIP
There are three output modes of main image and PIP in Output Mode, users can
select specific PIP mode based on the requirement, and conduct the operation like move,
scaling and clipping on the main image and PIP image respectively.

8
③Scaling
In Image View Area, select the image that needs to be scaled, set X, Y, width and
height of it in [Main] or [PIP], or you can click the white box in the bottom right corner of the
image and drag it with the mouse, finally click [Save].

9
④Clipping
Select signal source of the image that needs to be clipped in Input Signal Area, click
[Set] to enter the clipping interface.
In the clipping interface, check [Crop], and set X, Y, width and height in [Cropping
Settings], then click [Save] to complete.

10
⑤Picture Adjustment
Click [Picture Adjustment], enter the interface of picture adjustment. Check [Enable],
and adjust hue, saturation, brightness compensation and contrast ratio of the whole image,
then click [Save] to complete. After setting, you can click [Default Settings] to restore the
default values of every parameter, that is, hue and brightness compensation default to 0,
saturation and contrast ratio default to 100.
⑥Preset
In [Preset], 16 preset parameters can be saved, and every preset parameter includes
all parameter information of image output (signal source, PIP, scaling, clipping, picture
adjustment), users can directly load one preset parameter to display the image according to
needs, and don’t need to set up all parameters again.
After completing setting up all parameters of image output, select unnamed preset,
click [Save] to save the parameter to sending device; click [Load], send the parameter to
receiving cards. At the time, the image should display on the basis of preset parameter.

11
2. In Control Area, it displays the control area of each net port of Z4. Click [Import] and
select correct parameter file, click [Save] to save parameters into corresponding sender; or
set up the control area of each net port respectively (X, Y, Width, Height), click [Save].
3. EDID: Set sender resolution, the first one is the default as current resolution.

12
Click the dropdown button to display the resolution list to select the mainstream
resolution, and you can also customize the sender resolution, by setting the width/height
and frame rate.
Click [Save] after setting.
4. Network: Set up IP address, select “Obtain an IP Address Automatically”, then the
sender would auto obtain the IP address; or it would manual set up IP Address, Subnet
Mask and Default Gateway.

13
5. Other: Advanced Parameters Setting (Better Graylevel on Low Brightness, Mapping
From Sender, Output Mode, Sender Name), Test Mode Selection, Factory Restore.
6. Detect Receivers: Detect receivers under each net port of Z4 controller, and acquire
relevant information about the receivers (Port, Index, Version, Run Time, Support Chips).

14
5.2.2 Screen Parameters Setting
Observe the display screen with single cabinet as a unit, and if all cabinets themselves
could display normally {it is normal circumstance even the picture between cabinets is not
continuous}, please ignore this step and directly go to the next step.
Otherwise, configuration must be done as follows:
Click [Load], choose the correct parameter file.
Click [Send], to send the loading parameters to the receiving cards. At the moment,
each cabinet should display normally (it is normal circumstance even the picture between
cabinets is not continuous), then click [Save to Receiver] to save the parameters to the
receiving cards.
If each cabinet cannot display normally, you can conduct via the Basic Setting
(Module Information, Box Setting, Performance Setting) or Intelligent Setting, and you
can also contact with the LED screen engineers.
5.2.3 Connection Parameters Setting
Users don’t need to set up the control area of each net port respectively, but to the
connection relationship between the receiving cards under the network port loading via
each sender, and the software will auto calculate and set up the port control area according
to the connection relationship.
Detailed setting steps as follows:
1. Set up the quantity of receiving card
Set how many receiver (receiving card) that one port manages in Row Count and Col
Count (6*6 as an example) according to the actual loading of LED display, you will see LED
display mapping area from the right side (Viewing from the front of LED display).

15
2. Receiving Card Parameters Setting
Select the target sender and the net port from the left side, then select the
corresponding cabinets within net port actual control area and set the connection lines in
the mapping area.

16
There are two methods to set up:
①Use mouse to select one by one
In the mapping area, select the first receiving card based on the actual connection of
the net port (view from the front), and then set up the actual loading width and height of the
target receiving card in the right side (128*128 as an example).
Click the receiver (receiving card) one by one, according to actual connecting line, until
the last one for this network port loads.
②Connection Pattern
Aiming at the LED screen with standard connection lines, firstly set up the receiving
card information according to the actual loading width and height (128*128 as an example).
Select the connection line you want from the right side, then cover the corresponding
area of net port loading in mapping area, finally complete setting.
Note: As the cabinets have multiple and different specification (that is the inconsistent
capacity of the receiving card), you can select the different one to adjust separately after
completing setting.

17
3. Send & Save to Receiving Card
After setting up all the receiving card parameters and connection lines respectively,
click [Send] to send the correct parameter to the receiving card, and the screen should
display normally at this time.
Then click [Save to Receiver] to save parameters to corresponding receiving card
after confirming.
