Procedures for Selecting an HDMI Resolution and Frame Rate

The procedures below describe how to select the resolution in HDMI.
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
When you make a physical connection to an HDMI HDTV, a hot plug event will occur. There are two modes the
780/780AH can be set in when testing HDMI sink devices that determine how the 780/780AH 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 780/780AH 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 sink device. The 780/780AH 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 780/780AH will display all viable HDMI formats for the HDMI interface
whether they are supported by the display or not.
1. Select the Preferences from the 780/780AH top level menu. Navigate to the second page by touch
