4.2.2 Procedures for Selecting an Resolution and Frame Rate – HDMI and HDBaseT
The procedures below describe how to select the resolution for HDMI and HDBaseT outputs.
Note: You can create your own custom formats using the Quantum Data Format Editor. These procedures are
described in Creating and Using Custom Formats, EDIDs and Bitmaps.
When you make a physical connection to an HDTV or monitor, a hot plug event will occur. There are two
modes the 780C can be set in when testing HDMI or HDBaseT sink devices that determine how the 780C
responds to this hot plug event: 1) Hot plug formats On; 2) Hot plug formats Off.
When hot plug formats are On and a hot plug event occurs, the 780C will read the EDID of the display device
connected to its output port. It will then automatically configure the list available signal types (resolutions and
frame rates) to only those supported by the HDMI or HDBaseT sink device. The 780C will also be configured to
output the signal indicated in the EDID as the “preferred” timing. The preferred timing is highlighted in green
following a hot plug event.
When hot plug formats are Off, the 780C will display all viable HDMI or HDBaseT formats for the interface
whether they are supported by the display or not.
1. Select the Preferences from the 780C top level menu. Navigate to the second page by touch selecting the
More… key.
780C Multi-Interface Interoperability Tester – User Guide Page 26
January 19, 2017
Revision A9
2. Select the Hot Plug Formats mode to On or Off as desired. Refer to the screen above.
3. Touch select the Formats activation button on the Status bar OUT to access the Formats menu. Refer to
the figure below.
780C Multi-Interface Interoperability Tester – User Guide Page 27
January 19, 2017
Revision A9
The Formats menu appears as shown below (example HDMI):
4. Touch select the desired format and Frame Rate (example 2160p at 30Hz above).
Note: The 780C supports 4K formats at 60Hz but only in 4:2:0 sampling mode. When a 4K format is
selected and the frame rate is set at 60Hz the 780C will automatically configure itself to 4:2:0
sampling. Refer to the example below:
780C Multi-Interface Interoperability Tester – User Guide Page 28
January 19, 2017
Revision A9
For the HDMI formats, there are color codes that are applied to the Resolution and Frame Rate selections. The
following is a summary of their meaning:
A Resolution or Frame Rate with white lettering but with no outline – a Resolution or Frame Rate that
appears in the EDID and has a short video descriptor associated with it.
A Frame Rate with green lettering and with white outline – The Frame Rate that is currently selected.
A Frame Rate with red lettering but with no outline – The Frame Rate is not supported by the EDID for
that Resolution.
A Frame Rate(s) with green lettering and with white outline – The Frame Rate along with the currently
selected Resolution that is the “preferred” timing.
A Frame Rate with black lettering but with no outline – The Frame Rate is not supported by the standard
for the selected resolution.
Note: When you make a physical connection to an HDMI or HDBaseT HDTV or sink device, a hot plug
event will occur. If Hot Plug Formats is enabled on the Preference menu, when the hot plug event occurs,
the 780C will read the EDID of the display device connected to its output port. The output is automatically
set to the preferred timing which is highlighted in green following a hot plug.
4.2.3 Procedures for Enabling AVMute
The procedures below describe how to enable AVMute on the HDMI or HDBaseT output ports. AVMute is an
optional feature in HDMI or HDBaseT that enables a source to signal a sink to extinguish its audio and video.
The source, in this case the 780C emulating a source sets the AVMute Set flag in the general control packet.
The purpose of AVMute is to avoid audio artifacts when switching resolutions.
