<MODE>: Output signal mode
D = DVI,
H = HDMI 24bit,
1 = HDMI 30bit deepcolor
2 = HDMI 36bit deepcolor
<SIG>: Signal present
0 = No valid signal is routed to this port,
1 = Valid video signal is present.
<HDCP>: HDCP encryption status
0 = HDCP encryption is inactive,
1 = HDCP encryption is active.
<HPD>: Hotplug detection
0 = Hotplug detect signal is low,
1 = Hotplug detect signal is high.
O block: Actual output settings
<MODE>: Same as in G block.
<CSPAC>: Reserved for legacy reasons. Response is always ‘A’.
<CRANG>: Reserved for legacy reasons. Response is always ‘A’.
<SUBS>: Reserved for legacy reasons. Response is always ‘A’.
<HDCP>: Same as in G block.
M block: Attached device (monitor) information
<HSUP>: 0 = Sink device does not support HDMI
1 = Sink device supports HDMI
<AUTH>:
0 = HDCP aut
hentication f
ailed
1 = HDCP authentication is successful
<REP>: 0 = Attached device is not an HDCP repeater
1 = Attached device is an HDCP repeater
<YUV4>: 0 = Attached device does not support YUV 4:4:4
1 = Attached device supports YUV 4:4:4
<YUV2>: 0 = Attached device does not support YUV 4:2:2
1 = Attached device supports YUV 4:2:2
<AUD>:
0 = Attached device has n
o audio capab
ilities
1 = Attached device has audio capabilities
<PCM>:
This f
ield represents a b
yte in hexadecim
al format.
The binary bits show support for different audio bit rates.
bit 0 - Sink device supports 32kHz PCM audio
bit 1 - Sink device supports 44kHz PCM audio
bit 2 - Sink device supports 48kHz PCM audio
bit 3 - Sink device supports 88kHz PCM audio
bit 4 - Sink device supports 96kHz PCM audio
bit 5 - Sink device supports 176kHz PCM audio
bit 6 - Sink device supports 192kHz PCM audio
bit 7 - Reserved (Always 0 in this version of protocol)
<DC>: This field is a number is decimal format.
The binary bits show support for different color modes.
bit 2 - HDMI deep color 30bits/pixel mode is supported
bit 1 - HDMI deep color 36bits/pixel mode is supported
bit 0 - YUV444 color space is supported in DC modes
Info: The M block can be missing if there is no attached device on output.
