■About RGB Video Output

●Signal timing

The following shows the timing that signals are output from the RGB video output terminal. (XGA 60Hz speed or equivalent)

The video signal output is determined by whether “PC/OHP” or “OHP” is selected in “RGB- OUT Selection” on the “Setting 2” menu. See page E-45 for more information.
