Connecting Your DCX Set-top

Video Connection Options

The DCX set-top offers two different video connection options. HDMI allows you to view both

High-Definition and Standard-Definition TV programming. RF OUT (coax) connection allows you

to view only Standard-Definition TV programming.

To determine whether your TV features HDMI, or RF (coax) video, check the manual supplied

with your TV.

Use the guidelines below to determine the best video connection for your home entertainment

system.

Note: Only one video connection to the TV is required. HD video can only be viewed with HDMI video

connections.

HDMI — HDTV and SDTV

• HDMI offers higher quality HD video than RF Out (coax) video.

• If your TV has an HDMI input, this is for both audio and video. Connect a standard HDMI

cable to the TV and to the HDMI connector on your DCX set-top.

• HDMI output provides video and audio, so no separate audio connections are required if

you plan to use your TV’s speakers as the primary audio source.

Note: ARRIS recommends certified standard (category 1) HDMI cables for 1080i or 720p resolutions. A

certified high speed (category 2) HDMI cable is recommended for resolutions of 1080p.

RF OUT (coax) — SDTV

The RF OUT (coax) connector on your DCX set-top provides an SDTV video connection.

Note: RF OUT (coax) provides video and audio, so no separate audio connections are required.
