3 Tips for installation and operation

3.1 If multiple MLT-PROWALL-4K cascade function is executed, user can put MLT-PROWALL-4K in front of the video wall to do the setting, then install to the final place. User can also extend IR receiver to a location in front of

video wall for further settings.

3.2

Each MLT-PROWALL-4K is equipped with IR extenders. User can extend the cable distance up to 20m through

audio cable or connected with Cat 5/6 UTP cable.

3.3 OSD Lock / Unlock: When continuously press [MENU] key in IR Remote Controller for 5 seconds,

the

OSD function will be locked to prevent from the changes of the settings. To press MENU key for 5

seconds again, it will unlock OSD and user can manipulate the OSD again.

3.4 Picture menu in the OSD can only be activated while the input signal is not in color [Preset Mode]. To

select [Image Properties] [Custom] [Save], then user can activate [Picture] menu again.

3.5 [Image Setup] menu will not be activated if the input source is not from VGA.

3.6 Once finishing one video wall setting, user can apply the same setting value to next project with the same

configuration. It will save time for the installation and settings.

3.7 Please make sure the position of the LCD should match the output ports in MLT-PROWALL-4K, 3.8

MLT-PROWALL-4Kcan only be connected with the same size and resolution 16:9 LCD to keep correct position,

otherwise, customization is required for different size and aspect ratio LCD.

3.9 A poor signal cable connection may cause some noise on the display. Unplug the cable and connect it

again may solve the problem.

3.10 If the video wall aspect ratio is not the same as signal source, it may create abnormal aspect ratio in the

image. Users can select EDID in MLT-PROWALL-4K to let PC output a desired resolution. To apply different

[Overlap] value under [Video wall] menu can also change the aspect ratio issue.

5 Preset Display modes

5.1 LCD (TV) selection

a. Type of LCD: low cost LCD or TV can be used. No need to have matrix feature in the display panel.

b. Some Display Modes support TV at top down flip position to compensate the bezel size difference in TV.

c. Aspect ratio: based on 16:9 aspect ratio LCD (TV).

d. Output resolution: the default output resolution is 1920x1080 @60Hz.

e. All the LCD (TV) can support 1920x1080 input timing with 16:9 aspect ratio can be used, including

Bezel correction with 3.5mm and 4.9mm will apply to all

edges in the whole display. 1.5% bezel correction will only

apply to the edges adjacent with other TV. In below video

wall, TV3 bezel correction only applies to edge A & B but

not in edge C&D

There are 4 type of bezel compensation in display

mode list. Below % is calculated by total bezel size

divided by active display area in H&V:

a. No bezel correction: no information missing

b. 3.5mm mode: H=

d. 1.5% mode: H=

1.496090%V=2.552533%

The actual “bezel to bezel” size to be corrected is

based on the active display width (H) and height (V)

multiple the above % value.

For example, if user uses 55” panel (1218 * 685mm

active display) and select 4.9mm bezel correction

mode, the “Bezel to Bezel” value will be

H=1218*0.471163%=5.74mm

V= 685*0.837464%=5.74mm

The actual “Active to Active” size is

H=5.74 mm+0.3mm=6.04mm

5.6 Signal source output resolution selection

Video signal resolution setting will affect final video quality. Please follow below recommendation to set

signal source output resolution.

5.6.1 Basic concept for video source output resolution settings

Horizontal direction: If only single unit is required in horizontal direction, please set the horizontal output

resolution at 1920. If multiple units of MLT-PROWALL-4K are required in horizontal cascade direction, then

please set the horizontal output resolution at 3840.

Vertical direction: If only single unit is required in vertical direction, please set the vertical output resolution

at 1080. If multiple units of MLT-PROWALL-4K are required in vertical cascade direction, please set the

vertical output resolution at 2160.

5.6.2 Example for input resolution settings:

a. When using single MLT-PROWALL-4K, please apply 1920x1080 @60Hz input resolution.

b. For dual MLT-PROWALL-4K horizontal cascade, please set 3840x1080 @60Hz as input resolution.

c. For dual MLT-PROWALL-4K vertical cascade, please set 1920x2160 @60Hz as input resolution

For 2x2 four MLT-PROWALL-4K cascades, 3840x2160 @30Hz input resolution will get the best video quality.

e. For more complicated cascade, please follow the instruction in section 9.

5.6.3 How to set input timing resolution:

a. Please change the input resolution by [EDID] setting in page 49 or to change output resolution and select

correct aspect/scaling setting in PC output resolution setting.

b. If the output resolution is not standard VESA standard timing, user needs to set the output resolution from

display card custom output timing setting.

5.6.4 Please confirm the setting result by [INFO] menu from IR remote controller.

Mode 06A means DIP SW pin #6 shall be set to “ON” position.

“A” means this mode is only be achieved by rotating the image from

signal source. If the image is not rotated from signal source, then it is

necessary to rotate the image by MLT-PROWALL-4K through IR remote

controller. Please pay attention to content aspect ratio.

MLT-PROWALL-4K output connection

10.4 Video Wall Setting

The purpose for Video Wall Setting is for cascade multiple MLT-PROWALL-4K to become one video wall display.

It consists below functions:

[Output Mode]:To show display modes on OSD for easy display mode selection

[Zoom]: To split source image into different section for each MLT-PROWALL-4K.

[Pan]: to assign each image section to each MLT-PROWALL-4K at the right location.

[Overlap]: to re-allocate each image section at the right location for the cascade to become a complete big video

wall display.

The maximum video wall can be up to 15x15=225 MLT-PROWALL-4K. If each MLT-PROWALL-4K is connected

with 4x LCDs, then theoretically the total number of the LCD display can be up to 30x30=900 LCDs from single

signal source.

10.4.1 Output mode

[Output mode] shows pre-defined modes in MLT-PROWALL-4K. When user selects desired display mode,

the mode # will be showed at the bottom.

10.4.4 Overlap

The [Overlap] value will change the image capture area and change image scaling factor. In multiple MLT-PROWALL-4K cascade application, the

[Overlap] value adjustment in each MLT-PROWALL-4K should be the same so that the image will be the same size. User can use [Overlap]

adjustment to change aspect ratio in video wall image.

Example for two MLT-PROWALL-4K cascade

(Please see more details in section 7)

Overlap pixels for Zone A (Display Unit A) & B (Display Unit B) shall be the same. User can open [Overlap] menu

and select [RH Edge] for A & [LH Edge] for B, then increase the [Overlap] value gradually in both

[Display Unit A] & [Display Unit B] and will see two images from both MLT-PROWALL-4K coming closer until the

image edge match together.

[Pan] is to assign the split image location

for each Display Unit.

Horizontal value is calculated from LH to

RH direction and Vertical value is

calculated from top to bottom.

User needs to set H & V [Pan] value to

assign the location for each MLT-

PROWALL-4K to capture necessary section

of the image to build a big video wall

display.

[Overlap] is to align the location of each

Display Unit (MLT-PROWALL-4K) Đ

User can adjust the image location in

H&V position up to +_900 pixels.

Through [Overlap] adjustment, user can

align each Display Unit into the right

position in the video wall to become a

video wall display cascaded with multiple

10.5.5.2 Frame Lock and Free Run Mode

[Frame Lock] will ensure the input and output frame rate synchronize together. This is mainly for multiple

MLT-PROWALL-4K applications. If [Flame Lock] is disabled, the system will be in [Free Run] mode and

keeps continuous output timing. This will provide quicker input source or input timing change under

below conditions:

a. Input signal shall have the same refresh rate (i.e. 60Hz)

b. No HDCP compliant signal.

It is possible to see frame tear artifact if [Frame lock] is turned off while in multiple unit application.

10.5.5.3 [Box ID]

10.5.5.4 [Profile] Setting

[Box ID] is identification # in each MLT-PROWALL-4K for

individual RS232 or IR remote control.

MLT-PROWALL-4K ID No is from 1-99

After set Box ID, user can control MLT-PROWALL-4K

individually via IR Remote controller,

RS232 & Ethernet

IR control ID # is from 0-9 only.

[Profile] is to save and load MLT-PROWALL-4K

settings.

All settings from OSD menu need to be

saved in [Profile] and recall it when the

system is powered ON. Otherwise, user

will only see the settings by Dip SW. Dip

SW settings hold the 1st priority.

Application example: when cascade with two MLT-PROWALL-4K, user can set three display styles:

1. To show cascade image with single content across whole video wall.

2. To show two side by side contents across whole video wall.

3. To show one PIP content in cascaded image.

4. To show two PIP contents in cascaded image.

User can save these different display styles in MLT-PROWALL-4K and recall them by RS232 or remote controller.

Please note:

When execute system reset, Profile settings will remain the same without change.

If the settings in Dip SW on the front panel are different from the settings in [Profile], Dip SW setting will

have the 1st priority. For example, if your Dip SW selects Display mode # 02 and you select mode #05 via OSD.

Once you power OFF/ON the system again, it will show mode #02 but not mode #05. The same issue will

happen in PIP/POP settings, if you select a position and size of PIP image by OSD menu, once you power OFF/ON

the system, it will follow the setting in Dip SW but not OSD. You need to load the profile to get new OSD

settings.

10.5.5.5 [Network]

Five indexes can be chosen to save MLT-

PROWALL-4K settings and can be recalled by

IR remote controller or RS232 via [Load]

menu under [Profile]

Only RS232 under this Menu.

User can use external UART to Ethernet

converter to control MLT-PROWALL-4K through

Ethernet control system.

User can use simple button type RS232

controller to switch among different

Profile settings.

10.5.5.6 [EDID] setting

Selective EDID setting is added into MLT-PROWALL-4K. The purpose are as follows:

MLT-PROWALL-4K can support big range of input signal timing—from SVGA up to 4k/2k. In order to get the best video

performance, user needs to select different input signal resolution.

d. Different PC display cards have different setting and behavier. Many users may not be able to do the right

settings

e. High end media player or server can support big range of outputs—from 720p to 4k/2k. If no EDID

selection function, only one default EDID can be selected by media player. The system may not show the

best video wall output quality.

f. Different display modes may show different final image aspect ratio. User can ultilize different EDID setting

to change input signal timing and get different output image aspect ratio.

Activate EDID setting menu:

[Options]Đ [Setting]Đ [EDID]

Use IR remote controller to select

desired EDID.

After select EDID, the PC or medial will

automatically change the output timing

setting.

Press [INFO] key to check if the input

and output timing are set correctly.

User can save up to 5 settings into [Profile].

User can connect this RS232 controller with each

MLT-PROWALL-4K through RS232 cable in parallel. Đ

Click Profile button in RS232 controller to power

on/off the system or select display Profile.

If separate RS232 control is required, user needs to

set different [Box ID] for each MLT-

PROWALL-4K and put ID # into RS232

command.
