Multiple Projector Adjustment Overview

If you are combining images from multiple projectors on a network, you can assign one projector as the "master" and automatically adjust all the images to match the "master" image. If the projectors are not connected to a network, you can match each projector's images manually.

Note: Make sure all networked projectors are connected using LAN cables and have been assigned an IP address. Also disable the 4K Enhancement and Sleep Mode settings on each projector so they do not turn off during adjustment.

Turn on all the projectors.
Reset all projectors to their default values.
- Enable the Reset All Config setting.
- Reset the settings on the Color Uniformity menu to their default settings.
- Reset the settings on the Panel Alignment menu to their default settings.
- Set the Adjustment Level setting to All in the Color Matching menu, and select 0 for Red, Green, and Blue.
- Set the 4K Enhancement setting to Off.
- Set the Sleep Mode setting to Off.
Select one projector to be the basis for adjustment. Display test patterns from all projectors and select the one with the least color unevenness as the master projector.
Note: We recommend using the Grayscale, Gray Bars V, Gray Bars H, and White test patterns.
Set an ID for each projector and the remote control. Set the remote control to the master projector ID in order to limit the remote control to that projector.
For each projector, do the following:
- Run light source calibration on each projector.
- If you have installed the optional camera, perform color calibration on each projector.
- If you do not have the optional camera, or color calibration failed, perform color uniformity on each projector.
- Set the Color Mode setting to Multi-Projection.
- Set the Energy Saving Mode to Off.
Note: We recommend that you turn off the Run Periodically setting in Light Source Calibration. The automatic calibration may change your color adjustments.
Install all projectors in an appropriate location.
Caution:

Do not stack projectors directly on top of each other.

Note: Install the master projector in the central position, if possible, to reduce color unevenness in the center of the projected area.
Adjust each projector's physical position and angle to the screen.
Adjust the position of the image for each projector using lens shift.
Note: When adjusting the image height with vertical lens shift, adjust it by moving the image from the bottom to the top. If you adjust it from the top to the bottom, the image position may move down slightly after adjusting.
Adjust the zoom and focus for each projector.
Note: During adjustment, note the following:
- Wait at least 20 minutes before adjusting the images.
- Displaying the test pattern makes it easier to adjust the projection position and the shape. We recommend using the Grayscale, Gray Bars V, Gray Bars H, and White test patterns.
- We recommend not using Geometry Correction because image quality may decline and if the correction value is too large, image calibration may be difficult.
Connect all projectors to the network hub with LAN cables.
Adjust the arrangement of the images to create one large image from up to 15 projectors (tiling).
Adjust the brightness and tint of the images using the Screen Matching setting.
Adjust small differences in the images using the Point Correction setting.
Select sections of the images using the Scale setting.
Adjust the edges of the images using the Edge Blending and Black Level settings.
You can create one bright image by overlaying images from multiple projectors. Use the Simple Stacking setting in the projector menu to overlay the images from two projectors, or you can use the Epson Projector Professional Tool to overlay up to six projectors.
