X3% = Video signal status
0
= Video / TMDS signal not detected
1

X3^ = Power Save mode
0
= Full power mode (Default)
1
= Low power state
X3& = Screen saver status
0
= Active input detected; timer not running
1
= No active input; timer is running; output sync still active
2
= No active input; timer has expired; output sync disabled
X3* = Input AFL
0
= Disabled; (default); free running pixel clock is generated internally

X4) = HDMI input HDCP authorization status:
0
= Block HDCP encryption
1
= Allow HDCP encryption (default for input 3)
X4! = HDCP mode:
0
= Follow the input (default)
1
= Always encrypt HDMI outputs
2 = Follow the input with continuous DVI trials
3 = Always encrypt the HDMI outputs with continuous DVI trials
NOTE:
When enabled, the HDCP mode can be set as follows:
•
Follow Input — Encrypts the output only when required by the selected input
source.
•
Always Encrypt Output — Always encrypts the output, regardless of the HDCP
status of the selected input source.
•
Follow Input (with continuous DVI trials) — Encrypts the output only when
required by the selected input source. Use this setting when DVI sink devices
initially pass HDCP encrypted content, but intermittently display a green HDCP
notification screen after a power cycle or resuming from sleep mode.
•
Always Encrypt Output (with continuous DVI trials) — Always encrypts the
output regardless of the HDCP status of the selected input source. Use this setting
when DVI sink devices initially pass HDCP encrypted content, but intermittently
display a green HDCP notification screen after a power cycle or resuming from
sleep mode.
