Digital Image Enlargement Function The projector has a built-in image enlargement function that allows a maximum 10-fold enlargement both in the horizontal and vertical directions, thereby enabling image projection without the need for external enlargement equipment.
Select a zoom lens other than a short-focus fixed lens (ET-D75LE5). * Points to keep in mind A short-focus fixed lens does not permit zooming or lens shift and the projector needs to be placed at the center of each image. The lens causes slight distortion of the projected image around the lens perimeter and does not permit accurate image overlapping at the joint part.
1.6, a hot spot is visible but the blending is reasonable when viewed from the front. Photo 2 is the view from a side angle. Because the light from the near-side projector is stronger on the opposite side, the brightness is not well-blended.
Therefore the short focus zoom lens (3-chip DLP type: ET-D75LE6, 1-chip DLP type: ET-DLE100) are recommended. Despite its short focus, LE6 enables zooming and lens shift in the up-down and left-right directions along with a wide range of adjustment such as deviation correction of projector installation position. - 5 -...
Fig.3 (Side view) * The amount of lens shift varies by projector model and the actual lens used. The specific value should be checked with the specification. For example, use of the full up-down shift disables the left-right shift.
Regardless of whether a floor mount or ceiling hanging installation is used, the five screw holes furnished for the ceiling mount should be used to secure the projector. The screw holes for the legs of the set should not be used, because the deformation of the plastic cabinet by temperature affects the positional stability of the projector.
(3 places each on the front and back) and adjust the tilt of the projector with these bolts, and then fasten the bolts at the front and back alternately in a diagonal line little by little to finally achieve uniform torque at the end of adjustment.
The hanging bracket is equipped with an adjustment function to correct any shift of the projected image in the left-right and top-bottom directions as well as tilt in the left-right angle against the screen. The projector should be adjusted so that the lens centerline is perpendicular to the screen surface.
For each pair of a projector and multi-scan converter, the dot clock of the projector needs to be adjusted. In this case, the dot clock of the projector is adjusted by delivering the internal test pattern of the multi-scan converter. Connection with DVI cable is recommended.

Parallelism of the two projectors is easily checked by projecting a cross-hatch pattern from each projector and separating the grid lines by a dot in the horizontal and vertical direction. In the menu, turn on edge blending and the marker, and determine the width of blending. In this case, the blending width of the two projectors should have the same number (for example, 128 dots).
Video Projectors Adjust the installed angle of the projectors by completely eliminating distortion in the cross-hatch pattern. Make the cross-hatch patterns from the two projectors completely parallel. Overlap the two patterns, then turn on the blending and turn off the marker. - 13 -...
Even though the screen size matched horizontally, the hatch lines in between do not match. This is because the left side or the right side projector, or perhaps both projectors’ vertical angle do not match. And also please check and correct trapezoidal distortion in the vertical direction by comparing the screen frame with the cross-hatch pattern.
BRIGHT ADJUST menu to make the [joined] part visible. The next step is to reduce the brightness of the inside area produced by the excess light from the opposite projector by changing the values of the top, bottom, left and right (UPPER, LOWER, LEFT, RIGHT).
Match the color of the images using a high purity color and adding other colors. In the case shown on the left, green and blue are added to the left-hand projector, while reducing red from the right-hand projector. The key point of manual adjustment is not to exceed the level of the other side through over correction.
(Minolta CS-100/CL-100/CL200 or TOPKON SR-3) is used. A PC and projector are connected with an RS-232C cable combined with adjustment software (Panasonic Primary Colors Support Software (PPCSS)). * Because the system generates some color unevenness, measurement should be made near the image joint part.
