Scope of adjustment: is the coordinate unit area in the current operation area.All parameter adjustments will be valid for the selected unit area.
Color Adjust：
Image
Brightness:Adjust the brightness of the screen image;
Saturation: Adjust the depth of image color;
Contrast: Adjusts the brightness of the screen image;
Clarity: Adjust the clarity and focus of the screen image.
Color temperature
Red Gain：Adjust the color temperature to balance the red component, mainly affect the white field, the bright field;
Green Gain：Adjust the color temperature to balance the green component, mainly affect white field and bright field;
Blue Gain：Adjust the color temperature and light balance blue component, mainly affect white field and bright field;
Red Compensation：Adjust the color temperature dark balance red component, mainly affect the dark field, dark field;
Green Compensation：Adjust the color temperature dark balance green component, mainly affect the dark field, dark field；
Blue Compensation：Adjust the color temperature dark balance blue component, mainly affect the dark field, dark field;
Swatches:
First, make sure that the com setting is normal and can do basic control.
With administrator privileges, you can enter this adjustment area from the image adjustment option of the control software.
After all screens are switched to the unified channel, the signal picture is best for all-white field signal.
The principle explanation is to find a base screen on the splicing screen, then adjust the color temperature of the remaining screen to the same as the base screen, so as to achieve the result of the same color temperature effect.
Adjusted for use: First, determine whether the non-reference screen model is consistent with the reference screen, and then determine whether the screen backlight brightness to reach agreement with the reference screen, if not you can debug brightness backlight brightness or brightness, contrast parameters equivalent to as close to the base screen brightness. Then prepare to adjust the color temperature of the non-reference screen, first in the color table to quickly select and color similar to the color of the reference screen, and then manually adjust the color temperature of the gain / compensation of red, green and blue (gain mainly affects bright field, try to adjust the gain under the white field the RGB values; compensation mainly affects dark field), by fine-tuning reach base screen color consistent so far. Note: Positive reconcile anti-tune the color corresponding to the color table is the opposite, is positive tone screen colors and swatches of color is consistent, anti-tune the screen colors and swatches is the opposite, the default is the anti-tune settings Also you can pay attention to hover over the color table value corresponds to the block, this value shows the principle of complementarity of red, green and blue Huang Ziqing.
VGA Fine Adjust
Automatic adjustment: Under VGA channel, the system automatically adjusts image color and display position.
Note:The "automatic adjustment" process takes about 3-6 seconds, please don't do any other operation or turn off the power after clicking.
Reset：Click this button to restore the display unit of the selected region to the factory state.
Note:The "reset" process takes about 3-4 seconds. Please do not use any other operation or turn off the power after clicking.
For VGA signal, the second page (special adjustment) can be manually adjusted.
Horizontal Position：Adjust the horizontal position of screen image display;
Vertical Position：Adjust the vertical position of screen image display;
Clock：Adjust the vertical position of screen image display;
Phase：Adjust the image sampling phase.
These parameters are related to the implementation of "Position adjustment" in the PC channel. If the automatic adjustment cannot meet the requirements, such parameters can be manually adjusted (generally not recommended for manual adjustment).
Front-end brightness gain
Red: adjust the color temperature and brightness gain red component;
Green: adjust the color temperature and brightness gain green component;
Blue: adjusts the color temperature and brightness gain the blue component.
Under this kind of argument is PC channel, color adjust the relevant parameters, if automatic adjustment can not meet the need, can be manually adjusted, gain on behalf of the light field parameters, main show is contrast (general manual adjustment is not recommended).
Front-end brightness compensation
Red: adjusts the color temperature to compensate the red component;
Green: adjust the color temperature to compensate the green component;
Blue: adjusts the color temperature dark to compensate the blue component;
Under this kind of argument is PC channel, color automatically adjust the relevant parameters, if automatic adjustment can not meet the need, can be manually adjusted, the parameters of the compensation on behalf of the dark field, mainly for the ascension of brightness (general manual adjustment is not recommended).

Instructions on the use of time-limited functions:
Large screen splice box use time limitation function mainly consists of (time limit file generation system) and (registration interface), as follows:
Register time limit function interface.
The registration interface is embedded in the customer control software: click the register button.
Pop up the registration screen, then select the path of the file (the time limit function to save the file), click apply.
Function description:
The first step is to turn on the time-limit function: set the time-limit password, which must be kept in mind. Then enter start time and end time, length (no more than 50000 hours) cannot be empty; You also need to set the time for the prompt and then click the production limit file, as shown below.When the prompt message is turned on, click on the user registration interface to view the information not only to see the delay password (XXXXXXXX), but also to see the time opening and remaining time. Prompt time is the setting of how long the control system needs to be notified before the end of time.
The resulting time-limit file can be registered using the registration interface of the control software, as shown below.Click "please select path" on the registration screen, find the path of the time limit file, and find the back point to save.You can then click on the application to open the timed function, and the screen will have menu prompts.
The second step is to give customers a more delay file, delay the password for splicing box under the registration screen of the corresponding control platform, based on the information of view button displays a delay password, view information also has the button below (client) can see the delay password (such as: 69346230), corresponding to the input delay password and need to delay time, and then point to produce delay file.
When the customer is using it, find the delay file path on the registration screen, and then click the application button to delay it. The unrestricted time function is to produce the release file.To produce both the release file and the delay file, enter the total password and the corresponding time. The password must be kept in mind or saved in the time limit file to see the total password.
