<S/A>: Affected ports:
S = single-selected output
A = all outputs
<MODE>: Output signal mode:
A = Automatic (this setting gives a response as D/H/1/2),
D = DVI,
H = HDMI 24bit,
1 = HDMI 30bit deepcolor,
2 = HDMI 36bit deepcolor.
<CSPAC>: Reserved for legacy reasons. Set ‘X’ here.
<CRANG>: Reserved for legacy reasons. Set ‘X’ here.
<SUBS>: Reserved for legacy reasons. Set ‘X’ here.
<HDCP>: HDCP encryption:
A = automatic,
1 = always use.
Legend for response:
G block: General status information
<CON>: Connection sense:
0 = There is no attached sink device,
1 = Sink device attached (termination is present)
<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 auth
entication 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
