What should I do if the touch screen does not work?
❑ The HDMI input or the video input may be selected as the audio/video input source. Press the INPUT/OK button on the
computer (page 71) or the INPUT SELECT button on the remote commander (if supplied) (page 74) to switch the input
source to the computer input.
❑ You may have disabled the touch screen. Use the wireless mouse to click Start, Control Panel, Hardware and Sound,
and Pen and Touch, and then click to select the Use your finger as an input device check box on the Touch tab.
What should I do if I cannot tap on the exact spot that I intend on the touch screen?

a case, follow these steps to calibrate the touch screen with the Control Panel.
