Signal Settings .. Horizontal Position This sub-menu lets you adjust the horizontal position of the input source image within the projection area. • This setting is possible only when RGB is selected as the input source and digital zoom is not being used. • See “Signal Settings .. Ver tical Position” for details about how settings are saved. Signal Settings .. Frequency This sub-menu lets you manually control the frequency of the image. Normally, the projector is able to adjust the frequency automatically. If there are vertical bands in the projected image, however, it means that automatic adjustment is not possible for some reason. When this happens use this setting to adjust the image frequency. • This setting is possible only when RGB is selected as the input source and digital zoom is not being used. • Settings are saved for each signal type (XGA/60Hz, SXGA/60Hz, etc.). Note, however, that the number of signal type settings that can be saved is limited. Exceeding the limit causes the oldest setting to be deleted automatically. • If, for some reason, your manual frequency settings cause the image input from the computer to disappear from the projection, you can press the [AUTO] key to perform an auto adjust operation (page 7), which should cause the image to reappear. Signal Settings .. Phase This sub-menu lets you manually control the phase of the image. Normally, the projector is able to adjust the phase automatically. If there are color errors or flickering in the projected image, however, it means that automatic adjustment is not possible for some reason. When this happens use this setting to adjust the image phase. • This setting is possible only when RGB is selected as the input source and digital zoom is not being used. • See “Signal Settings .. Frequency” for details about how settings are saved. 30 Using the Setup Menu Signal Settings .. Noise Filter This sub-menu provides a choice of noise filter levels to remove digital noise from the projected image when RGB is selected as the input source. Note that the noise filter may not be able to remove certain types of digital noise. • This setting is possible only when RGB is selected as the input source and digital zoom is not being used. The setting is saved for the RGB input source only. • Turning off the projector automatically returns this sub-menu to its initial default setting (Normal). Input Source Specific Menu Items Input Source Available Items (Parentheses indicate defaults.) RGB Low, (Normal), High Component None S-VIDEO VIDEO No Signal Signal Settings .. Restore Menu Defaults This sub-menu returns all of the sub-menu items on the Signal Settings main menu to their initial default settings, except for the phase setting. • This operation is possible only when RGB is selected as the input source and digital zoom is not being used. • “Signal Settings” main menu “Vertical Position”, “Horizontal Position”, and “Frequency” settings are initialized for the current signal type (XGA/60Hz, SXGA/60Hz, etc.) only. • For details about the initialization procedure, see “To initialize the settings of a particular main menu item” on page 25. Screen Settings Screen Settings .. Keystone Correction This sub-menu lets you correct for vertical keystoning of the projected image. • Vertical keystone correction can be performed regardless of the currently selected input source. • A single setting is stored, which is applied to all input sources. 31 Using the Setup Menu Screen Settings .. Aspect Ratio This sub-menu lets you select the aspect ratio (ratio between the vertical and horizontal dimensions) of the projected image. Input Source Specific Menu Items Input Source Available Items (Parentheses indicate defaults.) RGB None Component (4:3), 16:9 S-VIDEO VIDEO No Signal None Setting Explanations 4:3: Sets the aspect ratio of the projected image to 4:3 (same as a standard TV screen). This setting is normally used when S-VIDEO or VIDEO is selected as the input source. 16:9: Sets the aspect ratio of the projected image to 16:9 (same as a movie screen or high-definition TV screen). Using this setting when the input source image is a 16:9 image that has been squeezed to a 4:3 image causes the image to be projected with its normal 16:9 aspect ratio. Setting Storage A different setting is stored for each input source. • When a component signal with an aspect ratio of 16:9 is sent from the input source, the aspect ratio of the projected image is automatically switched to 16:9. In this case, this setting cannot be changed. • Using this projector to reduce, enlarge, or otherwise alter an image for business purposes or public display may infringe upon the rights of the individual who holds the copyright of the image. 32 Using the Setup Menu Screen Settings .. Resize Image to Fit When RGB is selected as the input source and the video resolution of the connected computer is anything other than XGA (1024 . 768 pixels), “Resize Image To Fit” automatically enlarges or reduces t...
