PC Tool User Guide

The PC tool is an installation-free control software that supports both UART and network control. It consists of five parts: Matrix Switch, Signal Setting, FineTune:PQ, Video Wall and CEC Control. The UI is as follows:

Matrix Switch Page

1. You can select UART (with RS232 cable) or Network to connect device, baud rate is 57600 bps.
2. Select input source for each scaling output port.
3. “AllSet” function: Select HD A or B input source to all the scaling output.
4. Select input source for B/MAIN output port.
5. Select audio source for balanced audio output and Mini Toslink output.
6. Reset: The PC tool supports reset system to recover to factory configuration.
7. EDID Control: Click the “EDID” button on the Matrix Switch page, there will be a pop-up EDID control window.

a) Read each scaling output port downstream EDID and save as a BIN file.
b) Open an existing EDID file and write to the HDMI A and B input port as Manual EDID.
c) Select predefined EDID and write to HDMI A and B input ports.

Predefined EDID option like below:

Signal Setting Page
User can read the resolution of each input port and set the resolution of each scaling output.

Available output resolutions:

No.| Output Resolution Setting| No.| Output Resolution Setting
---|---|---|---
1| 3840x2160p 60Hz| g| 1440×1050 60Hz

FineTune:PQ Page
You can read and set the Brightness/Contrast/Saturation/Sharpness of each output.

Note: Suggest always use the default setting 50/50/50/50. Do not change the default settings without special conditions; If there is a problem after changing, click “Reset” to return to the factory settings.

CEC Control Page

If Auto Power On is enabled, every time when the product is turned on, it will turn on all displayers which are connected to it.
The product supports CEC function, including Power on/off, Volume+/-, Mute/Unmute.

Video Wall Page
This page is used to configure a group of outputs to function as a video wall.

1. Use the Video Wall Setting controls to change how the displays are arranged on the Video Wall page:
   a. Adjust the Rows and Columns sliders to change the displayed screen arrangement to permit proper Drag-and-Select of the desired screens for the video wall.
   b. Change the Available slider to set how many outputs will be used for the Video Wall.
   c. Click the “Set” button to change the Screen configuration.

2. Use the left mouse button to drag-select the screens that will be set for video wall mode.
   The selected screens will be shown as bright blue.

3. Use the right mouse button to open a menu.

4. Select “Screen Stitching” from the menu to program the video wall mode. The selected screens will now be shown as bright green.

5. To change the displayed image: right-click to open the pop-up menu and select the desired input from the “Input Select” menu option.

6. Repeating steps 2 ~ 5 above with a different set of outputs allows the creation of a second video wall. However, changing the Rows, Columns and Available sliders will automatically delete the current video wall set up when the “Set”  button is clicked. The following example shows a more unusual video wall set-up of two video walls with two 2×1 configurations:

Output Format| This option is only available for any screen that is not assigned to a video wall mode. It allows setting of the output resolution for the selected screen output.
Mirror| Two sub options : OFF ( default ), ON ( H+V Mirror)
When select “ON”, you can make 180° rotation with the selected screen.
Test Pattern| When Test Pattern is enabled, the output will display Color Bar pattern.

Bezel Setting
The Bezel Setting section allows the entry of values to compensate for the display bezel thickness. These values may be entered either as pixels (Type A) or as milli metre (Type B).
Type A Bezel Settings
The image size will be adjusted to allow for the number of pixels entered in each of the entry boxes. Click the “Set” button to view the effect of the new values.
Type B Bezel Settings
The image size will be adjusted to allow for the Inner and Outer display dimensions as entered in each of the entry boxes. Click the “Set” button to view the effect of the new values.
