Table 3: Additional HDMI Settings Field Definitions
Setting Description
HDMI/DVI Mode
Allows you to optimize the HDMI output to work with both DVI-equipped televisions
and HDMI-equipped televisions. HDMI is the default setting.
• 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
Allows you to adjust the color space used by the DCX3510-M to generate the video
signals on the HDMI output. YCC 4:4:4 is the default setting.
• 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
Allows you to specify the digital audio format delivered over the HDMI output by the
DCX3510-M. Options include Auto, L-PCM, and Pass Through. Auto option is the
default setting.
• Auto—Provides the digital audio format specified by the connected device (TV or
home theater receiver) when that device was first connected to the DCX3510-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 DCX3510-M passes the Dolby Digital audio to
the HDMI output. This option is most useful when connecting the DCX3510-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
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—The DCX3510-M automatically delays the audio signal on the HDMI output
by the amount of time requested by the connected HDMI device.
• Manual—The DCX3510-M delays the audio signal on the HDMI output by the
amount of time selected for the Lip Sync Delay setting.
• Off—The DCX3510-M will not delay the audio signal on the HDMI output.
