• For example, if HDMI 2 was assigned to “DVR”,
then a control device sending the DVR command
would select HDMI 2 on the MX180.
• Trigger out: A trigger can be assigned to the Input.
Available triggers are controlled in the trigger
setup menu. A trigger not assigned to a source
(Source, Source A or Source B) will not appear as
an option. See “Trigger Setup” on page 18.
Select Save to keep changes.
Video Setup
The Video setup menu has two sub menus: Video
Output and Video Input.
Video Output
SETUP>Video setup>Video ouput
This menu manages the default and preferred setting
for all video Outputs. In most cases the factory
default settings are recommended.
Main video output
assigns one of the 2 HDMI
outputs to be the Main output of the MX180.
For each HDMI Output (HDMI OUTPUT 1, HDMI
OUTPUT 2), a Default video source can be set. The
options are:
• Follow Main which will use the video source
of the HDMI Output assigned as Main Video
output
• Independent should be chosen if the Output
will be controlled externally such as from an
RS232 connection
• HDMI 1 HDMI 3
HDMI 5
• HDMI 2 HDMI 4
HDMI Audio out:
The default setting is
Passthrough which will send the audio from the
source. Audio can also be changed to Off or Zone B
audio can be selected for second zone applications.
USB or HDMI Inputs will not work for Zone B
HDMI.
Video Input
SETUP>Video setup>Video Input
In this menu, each HDMI Input can be customized
as to what information is advertised to the sources.
The HDMI Inputs send EDID (Extended Display
Identification Data) to the source to negotiate
acceptable formats.
HDMI Video settings include:
• Basic 3D supports input and output of
3-dimensional HDMI video signals. 3D works
if supported by the player and TV
• HDR (High Dynamic Range) improves the
range of color in contrast in a digital image
• Dolby Vision is a proprietary, dynamic HDR
format. By adjusting the picture on a scene-
by-scene or frame-by-frame basis, Dolby
Vision provides increased detail with better
color accuracy. Note that if multiple Dolby
Vision TVs are connected, the signal will only
be optimized for one TV with HDMI Output 1
having priority
• Deep Color is capable of up to 65,536 shades
per color. By comparison, RGB and YCbCr
can provide 256 shades per color. To take
advantage of Deep Color, both linked HDMI
devices must support it
• HLG (Hybrid Log Gamma) improves picture
quality like other HDR formats, but HLG has
the advantage backward compatibility to SDR
(Standard Dynamic Range) TVs
•
The HDMI 2.0 setting specifies if HDMI
2.0 block will be in the EDID or not. This
block tells source that 600MHz modes
are supported and scrambling control is
available. Basically, it’s there, if an old
source gets confused by an unknown EDID
block, so you can turn it off for such source.
The following options are available for the various
HDMI Video settings:
• Always - always advertise support for the
given resolution, regardless the supported
Outputs of any connected TV
• Never - never advertise support for the given
resolution, regardless of what the supported
resolutions of any connected TVs are
• One - advertise support for the given
resolution, if one of the TVs on the Outputs
support the resolution
• All - advertise support for the given
resolution, if all the TVs on the Outputs
support the resolution
If All is selected for HDR and one of the TVs is not
HDR compliant, then HDR functionality may be
disabled for all. Select One or Always in this case.
With Always, a non-HDR TV may not like the HDR
signal.
For the Audio setting, any selection other than
“PCM, bitstream, multichannel” will require the
source to do the decoding. Choices for audio
advertised to the source are:
• PCM only, multichannel (default)
• PCM stereo only
• PCM stereo up to 48kHz only
HDMI Bandwidth limit
is set to the default value
of 1200 MHz which is the highest option available.
If the MX180 is communicating with an older unit
that does not work well with formats that it is not
familiar with, you may wish to lower the HDMI
bandwidth limit.
