■ Input Signal Compatibility Table (PC video input terminal)The DT20 supports the signals marked by ● in the following table. Note that on some PC mod-
els, flickering and blurring occur in the projected image. If this happens, adjust the projected
image 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. When
using one of these signals, set the keystone compensation so that it does not distort the image.
