and PC resolutions.
If the copy of the built-in LCD screen is output in the laptop,
the output to an output monitor is limited to the resolution of
the LCD screen. As a result, black may be displayed at edges.
The problem can be solved by enlarging the display or
displaying only to the external monitor.
Cause/Check item/Solution
Does the selected aspect ratio of the output resolution match that
of the connected sink device? If not, set the aspect ratio of the sink
device.
Check the set aspect ratio of the input signal.
Check the monitor setting of the source device
(such as 4:3, 16:9, letter box and the like).
For analog input, signal that cannot be recognized by the MSD and
wrong aspect ratio may be applied. Perform the automatic
measurement in the "NEXT ASPECT" mode.
If interlace signal is input to a sink device that does not support
interlace signal, the video may flicker. Check the output resolution
of the sink device.
If the monitoring function for no-signal input works, the dual
monitor function may not work correctly. In this case, disable the
monitoring function.
If you set the HDCP output to "HDCP INPUT ONLY", some sink
devices may fail HDCP authentication. In this case, it may
temporarily not output video and audio when a channel signal
without HDCP support is input and then is switched to a channel
signal with HDCP support is input. In this case, set the HDCP
output setting to "HDCP 2.2" or "HDCP 1.4".
Set the total number of horizontal dots.
If you change the total number of horizontal dots, you may
sometimes have to set the start position of scanning and the active
area.
Adjust the tracking.
Adjust the tracking.
In order to execute the automatic measurement of the input timing,
the input video must have 25% or more brightness and its edges
(all sides) need to be in contact with the circumscribed rectangle in
the effective display area.
If the function that automatically adjusts the display position (upper
left of the screen) works while the automatic measurement is
executed, the video may move on its own. In this case, disable the
adjusting position function.
