Frequently Asked Questions - 55L35B5U HISENSE

How do I set up the splicing control software?

Extract the provided LcdWall.exe (no installation required). Ensure the RS232 cable is connected from your PC to the controller. Open the software, click on 'Serial Port Settings', refresh to detect the COM port, and open it. Then configure the wall layout (e.g., 2x2) in 'Curtain Wall Settings'.

What should I do if the display does not power on?

Check the power cord for damage, verify the power outlet is working, ensure the power switch is on, and check the fuse. If the indicator light is off, contact a professional.

How can I address the issue that some splicing units are not controlled?

Verify that the device addresses (IDs) are set correctly via the control software or remote. For individual units not responding, check the RS232 connection and address settings.

Does this model support 4K input?

Yes, it supports 4K input via HDMI 4K and DP ports (3840x2160 @ 60Hz). When using four 1920x1080 screens in a 2x2 mosaic, it can achieve point-to-point 4K display.

How do I clean and maintain the display?

Use a clean, soft cotton cloth to wipe the screen. Do not use hard objects, abrasive materials, or apply pressure. Avoid water splashes and place in a well-ventilated area away from dust and extreme temperatures.

Can I control multiple screens as one large display?

Yes, use the provided software to perform splicing. Select the desired screens, choose the signal source, and click 'Execute'. Physical bezel compensation can be adjusted via the 'Eliminate Border' option.

What is the purpose of the DP loop-through?

The DP output allows you to daisy-chain multiple displays without needing an external distribution amplifier. It supports 4K signals and simplifies cabling in multi-screen setups.

How do I update the firmware?

Copy the MERGE.bin file (from your supplier) to the root of a USB drive. Insert it into the display's USB port, navigate to System Settings > Software Upgrade, and click to start. Do not power off or remove the USB during the process.

What is the default administrator password?

The default administrator password is 111111. You can change it in the software settings, but remember the new password.

How do I reset the display to factory settings?

In System Settings > System Adjustment, click 'Reset'. Note: only do this if recommended by the manufacturer, as it restores all settings to defaults.

2) operate of the software

Extract the splicing control software.RAR, you can get the following files: user logo, automatically adjust the picture VGA, serial debugging, LCDWall.exe, LcdWall.exe.manifest, MWS_Cfg.ini. The control software is a green version, no need to be installed. Run the Lcdwall.Exe, and then it appears as shown in Fig.1.

(Note: all the operations must be open in the serial port)

Fig.1

Note: The contents of interface may differ from the example shown above with the different version of the software; you may consult our relevant customer service staff. The function description of the operation interface is shown in Fig.1:

Operation zone	each grid element represents the corresponding controlled screen, you can select the corresponding controlled unit through the keyboard or the mouse clicking or dragging.
Function zone	contains commonly used function buttons.
User's title zone	the users can change the displays of the title according to their own requirements.
Status zone	displays the port state and the operation authority state, and the current local time, date, etc.

4.1 Settings of the software

Click the function diagram of "serial port settings", the interface is shown as in Fig.2.

Note: Click "refresh" button to mate COM automatically, and then click "open" to achieve connection.

Fig.2

The ranks in the "curtain wall settings" can be set according to the actual needs. The following is an example of 2 by 2 in the WinXP

(Note: if the wall is 2 by 2, then the splicing array must be set to 2 by 2, otherwise it will fail to splice)

4.2 Address settings for the splicing controller (setting ID)

System settings ---- sequence number (setting ID) changes:

each equipment's original serial number is "1", the users can set the screen sequences according to their own needs. Administrator users can go into the "curtain wall settings" to fill in the corresponding target sequence numbers according to each screen machine's code, then click "modify" to complete modification of the serial number of the screens (Note: this function will read the screen machine's code and modify the corresponding serial number of the screens when modification).

(Note: the "system settings" button can only be operated when inputting the administrator password. The remote controller can only be used in the multimedia channel. The default administrator password is 111111, which can be modified. Please keep the new password in mind when modified)

Fig.3

4.3 Single machine operation

Fig.4 is showing the relative options.

You can choose a single or multiple splicing units to set on/off of the unit(s), and you can also right click the mouse to set the input signal, or click on the "image freezing" to freeze the current image, and click again to cancel the freezing.

Fig. 4

4.4 Splicing operation

Splicing operation is as shown in Fig.5. For multiple splicing units, 2 by 2 for example, after selecting the 4 screen, select the signal source in the signal sources, click the "execute" button to complete the splicing. You also can click on the "image freezing" to freeze the current image, and click again to cancel the freezing.

After splicing, there will be physical seams between the units, you can select the "eliminate the border" and set up corresponding values to realize the image coherence (Note: the frame value is set according to the physical frame of the screen. For example: the length of the LTI460HA03 frame is 10mm, and the value should be set to 10).

Fig.5 shows the effect of removing frames.

Fig.12

Terms interpretation:

Backlight brightness	it is used to adjust the brightness of LCD lamp, and has nothing to do with signals.
Automatic adjustment of the VAG color	if the value is caught incorrectly in the VGA state, the display color is not normal. Now you can click this button to catch it again, it can be repeatedly clicked (Note: it is used when single screen display of the splicing unit).
No-signal blue screen	when you click on this button, the no-signal blue mode is on. If there is no signal, the screen displays blue. When signal is connected, it will display normally.
No-signal black screen	when you click on this button, the no-signal black mode is on. If there is no signal, the screen displays black. When signal is connected, it will display normally (Note: this function is practical in some special occasions such as at night time).
Reset	you can click this button to restore the machine to original state when your settings are in chaos (Note: do not reset unless you get the permission from the manufacturer)
Change of the curtain address (i.e. splicing control box address)	all the splicing control boxes addresses are originally set to “1”, the users can set the addresses according to their own needs. Firstly to display the screen machine codes, as shown in the bottom of the screen (see Fig.13 and Fig.14), then set the corresponding addresses, click “modify” to complete the changes.

Fig.13 Machine code

Fig.14 Machine code and screen address

6) Fill the machine code and the screen address displayed in the control software into the corresponding boxes and then click "modify" to finish it. All the default addresses of the display screen are "001".

For example, in the 2 by 2 splicing screen, the machine code 15569 is showing for the fourth screen counted from left to right by column, as shown in Figure 11. When you put the 15569 into the frame, the address box of the curtain wall has been changed into 4, click “modify” to finish it, and then close it to go on for the next one.

Software upgrade: copy the software MERGE.bin from the relevant personnel of our company to the root directory of a USB drive, do not change the file's name, then insert the USB drive into the USB interface, click "software upgrade", the screen will turn into blue, and you can see the update progress of the software in the upper right corner. At the same time, the power indicator light will flash green/orange alternately. It will automatically reboot after the upgrade is completed

(Note: during the upgrade process, do not power off or pull out the USB drive, otherwise it will damage the machine).
