[Edge Blend] - Setting Procedures and Example
In edge blending procedures adjust the color from projector s first . U ser s can also use [Color] function to do
further adjustment. Please note that, any color adjustment will reduce the color dynamic range.
Edge Blend has the facility to enlarge the display screen area and change the aspect ratio with multiple projectors.
Three elements are required for edge blending:
1. To perform geometry alignment the projectors have the same size (warp function).
2. Video Wall function can split , crop and assign the proper image to each projector.
3. E dge blending allow projectors to be become a seamless image. Below is example of the procedures for three
projector edge blending. It is also possible to use Gwarp PC tool for sophisticated curve adjustment.
a. Excel Spread Sheet is available to for user to determine the projectors (resolution, quantity, lumens and throw
ratio) and information for system installation. Based on this information, user can make detailed project plan for
the complete system.
b. Placement of the Projectors:
- Select projectors with higher contrast ratio (above 3000:1 is recommended) and set projectors at reasonable
distance from the screen with 200-500 overlap pixels (or 40cm-100cm overlap width) between two projectors.
- Use removable tape as temporary marks to indicate the image edges for each projector (based on the data from
Excel Spread Sheet). Each projector should have the same display size. Otherwise the grid size in each projector
will be different and the blending image will become blurred.
- To project each projector a little over the display range for further geometry adjustment.
Please try to install the projector with less keystone image.
- To set parallel vertical overlap edges between 2 adjacent projectors and let the positions of the lines close to
pre-marked positions will get better video quality after Edge Blending image.
c. Projector setting:
- Reset projector to default setting.
- To disable “Auto Alignment” function if user wants to use VGA analog input signal to avoid image shift during
projector switching ON/OFF process.
- Disable Auto Keystone function and set new keystone value to let two vertical edges in adjacent image in parallel
vertically.
- Select a Display Mode with 2.2 gamma curve will reduce the color difference in overlap area for video display.
User needs to test with different Display Mode setting based on the application.
- Use projector internal color adjusting function to adjustment the color variation among projectors before
implement edge blending.
d. MLT-EDGEPRO-2X2 Setting:
- Reset MLT-EDGEPRO to default setting.
- Select the input source and best output resolution to match projector native display resolution.
- Set [OSD Time Out] to [OFF] to maintain the display of OSD and Grid Test Pattern during the installation
period.
- To do [Color] adjustment for the projector with bigger color deviation
