Description
HDMI/DVI Mode
The
HDMI/DVI Mode
setting allows you to optimize the HDMI output to work
with both DVI-equipped televisions and HDMI-equipped televisions. By default,
this option is set to HDMI. The options are used as follows:
•
HDMI
—Optimized to work with an HDMI television or home theater receiver.
•
DVI
—Optimized to work with a DVI television or display device (connected via
an HDMI-to-DVI adapter).
Color Space
The
Color Space
setting allows you to adjust the color space used by the
DCX3501-M to generate the video signals on the HDMI output. By default, this
option is set to
YCC 4:4:4
. The options are used as follows:
•
YCC 4:4:4
—Generates video signals within the YCC color space.
•
RGB
—Generates video signals within the RGB color space.
Note: Adjusting these settings could result in a loss of video. Only a professional
installer or someone with a good working knowledge of the color spaces
supported by the TV should change this setting.
Audio Output
The
Audio Output
setting allows you to specify the digital audio format delivered
over the HDMI output by the DCX3501-M. Options include
Auto
,
L-PCM
, and
Pass Through
. By default, the Auto option is selected. The options are used as
follows:
•
Auto
—Provides the digital audio format specified by the connected device (TV
or home theater receiver) when that device was first connected to the
DCX3501-M.
•
L-PCM
—Provides all audio in the Linear Pulse Code Modulation digital audio
format. The L-PCM format is widely supported by most HDMI televisions and
home theater receivers.
•
Pass Through
—Provides the same digital audio format on the HDMI output as
is provided with the program being viewed at that time. For example, if the
program has a Dolby Digital soundtrack, the DCX3501-M will pass the Dolby
Digital audio to the HDMI output. This option is most useful when connecting
the DCX3501-M to a home theater receiver that has HDMI switching capability.
Note: Adjusting these settings could result in a loss of audio. Only a professional
installer or someone with a good working knowledge of the digital audio formats
supported by the TV and/or home theater receiver should change this setting
Lip Sync
The
Lip Sync
setting allows you to adjust the amount of time the audio signal is
delayed with respect to the video signal on the HDMI output. Some HDMI
televisions and home theater receivers add an extra delay to the video signal
during processing which can produce an effect where the audio noticeably
“leads” the video.
By default, this option is set to
Auto
. The options are used as follows:
•
Auto
—Automatically delays the audio signal on the HDMI output by the
amount of time requested by the connected HDMI device.
•
Manual
—Delays the audio signal on the HDMI output by the amount of time
selected for the
Lip Sync Delay
setting.
•
Off
—Does not delay the audio signal on the HDMI output.
