Cause/Check item/Solution
[13] Does the PC resolution (you can check it in "Properties" of the PC)
match the resolution that is output from the PC (you can check it in
"9.22.3 Input signal status". If not, set the EDID and PC resolutions.
For laptops, if the "copycdesktop" is enabled, the output to an
external monitor is limited to the resolution of the laptop's native LCD
screen. As a result, black may be displayed at edges. The problem
can be solved by enlarging the display, extending the desktop or
displaying only to the external monitor.
Does the selected aspect ratio of the output resolution match that of the
connected sink device? If not, adjust 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 inputs, signals that cannot be recognized by the MSD may
possibly be output with the wrong aspect ratio. Perform the automatic
measurement in the "NEXT ASPECT" mode.
If an interlace signal is input to a sink device that does not support
interlace inputs, the video may flicker. Check the format settings for the
MSD's output port driving the sink device.
If the monitoring function for no-signal input is enabled, the dual monitor
function of your PC 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, the sink may temporarily stop
presenting video and audio when switching between input signals with and
without HDCP support. In this case, set the HDCP output setting to
"ALWAYS".
Set the total number of horizontal pixels.
If you change the total number of horizontal pixels, you may sometimes
have to set the start position of scanning and the active area.
Adjust the input tracking setting.
Adjust the input tracking setting.
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 image 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 automatic
measurement of start position function.
