When the computer has a DVI output connector, use a commercially available converter cable to
connect the computer to the projector's HDMI input connector (only digital video signals can be input).
Also, connect the computer's audio output to the projector's Computer 2 audio input connector. In this
case, switch the HDMI setting at on-screen menu's audio selection on the projector to [COMPUTER2].
To connect the computer's DVI output connector to the projector's DisplayPort input connector, use a
commercially available converter.
• When Viewing a DVI Digital Signal
• Use a DVI-to-HDMI cable compliant with DDWG (Digital Display Working Group) DVI
(Digital Visual Interface) revision 1.0 standard. The cable should be within 197"/5 m long.
• Turn off the projector and the PC before connecting the DVI-to-HDMI cable.
• To project a DVI digital signal: Connect the cables, turn the projector on, then select the HDMI
input. Finally, turn on your PC. Failure to do so may not activate the digital output of the
graphics card resulting in no picture being displayed. Should this happen, restart your PC.
