The Correction interface in VMP contains two main functions, Seam (seam correction) and Module (multi-batch adjustment).
¶ Seam Correction
In installing modules or cabinets, bright seam will appear when the two modules or cabinets are too tightly and the pixel spacing on the seam is too small.
Conversely, dark seam will appear if the installation is too loose, resulting in too large pixel spacing on the patch.
The seam correction is used to mitigate this phenomenon.
After entering VMP, click Correction in the top function bar.
Click on Seam at the top of the function area to access the Seam Correction interface.
Seam correction can only be optimized on the software side and cannot be eliminated. If want a perfect display, you need to re-install the modules and cabinets with equal spacing.
¶ Calibration Effect Switch
The Seam Correction interface only displays the Brightness Calibration and Brightness & Chroma Calibration switches. Seam Correction coefficients are stored independently on the receiving card.
When the user connects the device, the Seam Correction switch will be displayed on the top of the function area, so that it can easily managed. The calibration effect switch is only for the user to view the correction effect under different calibration effects.
¶ Select Mode
¶ 3 Cabinet Mode
¶ 3 Module(LDM) Mode
¶ 1 Erase Mode
Select the area and click erase to remove all the seam correction coefficients.
¶ 1 Cabinet Structure Override
Override the module layout in the cabinet while keeping the cabinet resolution unchanged.
Application Scenario:
1)The layout of the cabinet modules on the software side does not match the actual layout of the cabinet modules.
2)The seams caused by the installation method are not in the smallest unit of the module, such as the seams half the length of the side seams of a module.
¶ Coefficient Adjustment
Brightness adjustment and various test patterns are provided to help users check the effect of seam correction in various situations.
Quick Adjustment and Fine Adjustment:
Quick Adjustment has 10 times the step units of Fine Adjustment.
Shortcut:
With keyboard and mouse:
Mouse on the scroll wheel of the software interface, scroll the mouse wheel as usual.
Keyboard only:
Keyboard number 1 and keyboard up and down keys pressed at the same time.
Restore:
Abandon the current correction effects and restore the screen seam correction to the last stored state.
Reset:
Abandon all the seam correction effects and restore the screen to the never-adjusted state.
Cursor switch:
Control switches for selected seam markers on the screen.

¶ Multi-batch Adjustment
When a screen for various reasons, using different batches of cabinets or modules, results in the screen due to batch problems resulting in some of the brightness or chromaticity display inconsistency, then it needs the multi-batch adjustment.
Once in VMP, click on Correction in the top function bar.
Click Module at the top of the function area to enter the Module Correction interface.
The Module Correction interface is a specialized solution to the problem of multiple batches, collectively referred to as multi-batch adjustment.
¶ Calibration Effect Switch
Only the brightness and brightness & chroma calibration switch will be displayed.
The multi-batch Adjustment interface needs to be fused with brightness and chroma calibration or brightness calibration coefficients for storage.
Therefore, user have to enable a calibration effect in this interface for storing the effect of multi-batch adjustment.
¶ Select Mode
¶ Cabinet and Module Mode
¶ Cabinet Structure Override
Application Scenario:
The case in which the cabinet module layout on the software does not match the actual cabinet module layout.
¶ Coefficient Adjustment
Shortcuts
With keyboard and mouse:
the mouse is placed on the software interface scroll wheel, scroll the mouse wheel as usual
Keyboard only:
keyboard numbers 1-4 plus keyboard up and down keys.
Cursor switch:
Control switches for selected seam markers on the screen
Restore:
Abandon this adjustment effect and restore the effect to the last stored state.
There is no Reset function here, i.e., once the multi-batch adjustment is saved, it is fused with the correction coefficients and cannot be restored to the unadjusted state except for reading back the unmodified calibration coefficients.
Brightness adjustment and multiple test patterns
Video source and white pattern:
The adjustment interface shows WRGB four-color adjustment bias.
RGB pattern:
The adjustment interface shows RGB three-color adjustment bias.
Notes:
Since the multi-batch adjustment coefficients need to be stored in fusion with the brightness or brightness and chroma calibration coefficients, please make sure that one calibration effect is turned on before adjustment.
¶ Coefficient Export
The export coefficients function only supports exporting adjustment coefficients for a single module or cabinet.
Click on an adjusted module or cabinet and click Export Coefs to export the coefficients and store them to PC.
Note:
The coefficients of multi-batch adjustment support cross-mode upload, and the cross-mode upload interface does not display the file information. If the user has multiple coefficient files with different modes, please pay special attention to differentiating the coefficient file naming.
¶ Coefficient Import
Select the screen range (cabinet or module) for which coefficients need to be imported and click Import Coefs to select the multi-batch coefficient file from the local area to which the coefficients need to be applied. After successful import, check the effect of multi-batch adjustment and click Save after confirming.
Multi-batch adjustment coefficients support cross-mode upload, i.e.:
Local Cabinet - Cabinet Mode
Local Module - Module Mode
Local Cabinet - Module Mode
Local Module - Cabinet Mode
¶ Save
After clicking Save, the user's current adjustment will be fused with the calibration coefficients opened by the user in this interface, and the adjustment effect can not be undone, so please confirm the accuracy of the effect before saving the operation.
For this reason, it is strongly recommended that users export a copy of the calibration coefficients to be stored locally before performing multi-batch adjustment!
¶ Discard
When the user has made a coefficient adjustment in the Multi-Batch Adjustment Interface, but has not saved it, if the user needs to switch to another interface of the VMP, the software will pop up a prompt window as shown on the left.
It will ask if the previous adjustment needs to be saved. If the user clicks Save, the multi-batch adjustment will be saved, if the user clicks Discard, any adjustments made since the last Save will not be saved.
¶ Copy and Paste
The multi-batch adjustment coefficient supports copy-and-paste operations.
Right-click on any cabinet or module that completes the multi-batch adjustment
Ctrl + C to copy the coefficient
Choose the range that requires an adjustment coefficient
Ctrl + V to paste the coefficients
