ARC (Audio Return Channel)
ARC lets the TV output digital sound to an audio device and input digital sound from the same
audio device through one HDMI cable. However, ARC is only available through the HDMI (ARC)
port and only when the TV is connected to an ARC-enabled AV receiver.
DVI (Digital Visual Interface)
Connecting the TV's DVI connector to a computer's DVI connector via an HDMI-to-DVI cable
lets you use the TV as a computer monitor. However, HDMI-to-DVI cables deliver video signals
only. You must connect a set of speakers to the computer using a separate cable to hear the
computer's audio.
HDMI (High Definition Multimedia Interface)
HDMI is a method of transmitting both video and audio signals via a single cable.
Dynamic versus Static IP Addresses
If the network requires a dynamic IP address, use an ADSL modem or router that supports
the Dynamic Host Configuration Protocol (DHCP). Modems and routers that support DHCP
automatically provide the IP address, subnet mask, gateway and DNS values the TV needs to
access the Internet, so they do not have to be entered manually. Most home networks use a
dynamic IP address.
If the network requires a static IP address, enter the IP address, subnet mask, gateway, and DNS
values manually when setting up the network connection. To get the IP address, subnet mask,
gateway and DNS values, contact your Internet Service Provider (ISP).
If the network requires a static IP address, use an ADSL modem that supports DHCP. ADSL
modems that support DHCP also allow static IP addresses.
