Note that on some PC mod-els, flickering and blurring occur in the projected image. If this happens, adjust the projectedimage in the Sync Adjustment menu.• When the input signal resolution is lower than 1024✕768 dots, enlarge the display. When it is higher,compress the display.• Signals marked with an * may become fuzzy if too much vertical keystone compensation is applied. Whenusing one of these signals, set the keystone compensation so that it does not distort the image.
