Audio connection:
• For HDMI/DisplayPort, the default setting of audio source is a TMDS signal with HDMI/DP
cable. Users can use an external audio source if an audio cable (ø3.5-mm stereo mini) is
connected to the CVBS/Audio In connector. Open the OSD Menu and select Sound > Audio
Source > Line In. (See "OSD (On-Screen-Display) Controls" on page 32).
• For DVI-D, connect an audio cable (3.5-mm stereo mini), to the CVBS/Audio In connector.
Because the audio automatically switches to Line In, the audio is output simply by connecting
the cable.
It may take a moment for the signal to appear on the screen.
