51 4. Multi-Screen Projection Things to note when installing projectors • Leave sufficient space on the left and right of the projector so that the air intake and discharge outlets of the projector are not obstructed. When the air intake and discharge outlet are obstructed, the temperature inside the projector will rise and this may result in a malfunction. • Please do not pile up the projectors directly on top of one another when installing them. When the projectors are piled up on top of one another, they may fall down, resulting in damage and failure. • Installation example when using two projectors The following installation is recommended when combining the installation of two projectors for multi-screen projec- tion. Please leave a space of at least 10 cm between the air intake/discharge outlet and the wall. [Installation example] Air intake opening Air discharge outlet Cabinet Cabinet Cabinet Air dis- charge Air intake Front Right side Back WARNING Please request the retail store for special installation services such as when mounting the projector to the ceiling. Never carry out the installation by yourself. The projector may fall down and result in injury. Please use a sturdy cabinet that can withstand the weight of the projector for the installation. Please do not pile up the projectors directly on top of one another. NOTE: • For the range of the projection distance, please refer to the Appendix “Throw distance and screen size”. (→ page 158)

56 4. Multi-Screen Projection ❸ Displaying a Picture Using [EDGE BLENDING] A high resolution video can be projected on an even bigger screen by combining multiple projectors on the left, right, top and bottom. This projector is equipped with an “EDGE BLENDING Function” that makes the edges (boundaries) of the projection screen indistinguishable. NOTE: • For projector throw distances, refer to “Throw distance and screen size” on page 158. • Before performing the Edge Blending function, place the projector in the correct position so that the image becomes square in the appropriate size, and then make optical adjustments (lens shift, fo\ cus, and zoom). • Adjust the brightness of each projector using [LAMP ADJUST] under [LAMP MODE]. In addition, use [REF. WHITE BALANCE] to adjust the [CONTRAST], [BRIGHTNESS] and [UNIFORMITY]. Before explaining use of the Edge Blending function This section explains the case for “Example: Placing two projectors side by side”. As shown, the projected image on the left is referred to as “Projector A” and the projected image on the right is referred to “Projector B”. Unless otherwise specified hereinafter, the “projector” is used to mean both A and B. Example: Placing two projectors side by side Edge Blending area Projected area Projected area Projector A Projector B
