Chapter 3 Projecting 5 Turn on the equipment connected to the projector. 6 Select the input signal to be projected on the screen. Click one of the INPUT SELECT radio buttons on the SCREEN CONTROL window. Input A: Selects the signal input from the connectors on the preinstalled input board in the INPUT A section. Input B to Input D: Select the signal input from the connectors on the optional input board in the INPUT B to INPUT D sections, respectively. Quad-screen Mode: Projects images in quad-screen mode. Images from four input signals are projected on the screen simultaneously. The image from signal input from INPUT A is displayed on the upper left of the screen, that of the signal from INPUT B on the upper right, that of the signal from INPUT C on the lower left, and that of the signal from INPUT D on the lower right. Note Select the appropriate input signal from "Signal Mode" of "Input Source" in the PICTURE CONTROL window. Improper setting may cause deterioration of the picture. For details, see page 62. Notes when quad-screen mode is selected in step 6 • When projecting moving pictures in quad-screen mode, all the input signals should be genlocked to synchronize with each other with a phase difference of less than 5 µsec. The projected moving picture not synchronized with the reference picture will appear to have dropped frames. A moving picture on the upper left screen for quad-screen mode is regarded as a reference picture. If you project still pictures and moving pictures together, select the upper left screen for the moving picture. • When projecting signals with vertical frequency of more than 1080 pixels such as UXGA and WUXGA, a part of the displayed image may be invisible. 7 Click the "INSTALLATION" button to open the INSTALLATION window. 8 Adjust the focus with the "Focus +/-" buttons under "LENS CONTROL." 9 Adjust the picture size with the "Zoom +/-" buttons. 10Adjust the focus again with the "Focus +/-" buttons. To cut off the whole screen Click the "ON" button of "MUTING." The whole screen appears in black. To restore the picture, click the "OFF" button of "MUTING." To turn off the power 1 Click the "POWER STANDBY 1" button, then the "OK" button in the displayed confirmation dialog. The MAIN and LAMP indicators flash green. The projector detects the temperature of the lamp and the fan continues to run for 3 to 15 minutes to reduce the internal temperature. When the fan stops running, the MAIN and LAMP indicators light red. 2 Set the power switch to the lower position. Note Do not switch the power switch to the lower (off) position while the fan is running. Doing so stops the fan before the temperatue of the lamp has been cooled down sufficiently and may damage the unit. Projecting a 4K Signal in QuadScreen Mode 4K signals separately input from four input boards can be projected as one 4K image in quad-screen mode. When projecting a 4K image, all the input signals should be genlocked to synchronize with each other with a phase difference of less than 5 µsec. Set "Signal Mode" and "I/P Mode" of "Input Source" in the PICTURE CONTROL window to the same settings for INPUT A to INPUT D. After completing the above, click the "On" radio button with "PROGRESSIVE DISPLAY MODE" in the INSTALLATION window. Notes • "PROGRESSIVE DISPLAY MODE" is effective when the signals below are input in the same refresh rate. - Four 1920 × 1080 signals - Four 2048 × 1080 signals - Four SXGA+ (1400 × 1050) signals "PROGRESSIVE DISPLAY MODE" cannot be selected for any other signals that are not stated above. • Depending on signal types, there are certain limits when displaying the signal. To check whether the signal can be projected as 4K images, see the following table. 59 Projecting the Picture
