Problem
Part of video is cut off
or black is displayed
at edge(s).
Black appears at top,
bottom, right and left
on PC video or only
part of the PC video is
displayed, and the
rest is displayed by
scrolling with the
mouse.
Video is reduced
vertically or
horizontally.
Video flickers.
PC's dual monitor
cannot be set or the
setting is canceled.
It takes a long time to
output video after
video input is
switched.
Part of the bitmap is
cut off, or bitmap is
not displayed on the
full screen.
Cause/Check item/Solution
[7] Check the overscan setting.
[8] Settings of the display position or size are not changed?
Note: Display position and size can be set for each input or output.
[9] If aspect ratios of the input signals and output resolution do not
match, video may be cut off or a black bar(s) may be displayed at
edge(s) automatically depending on settings. If the video is displayed
on the full screen by setting the aspect ratio to "FULL", there is no
problem.
If the aspect ratio does not match, you can select a) or b) below:
a) video will be cut off
b) a black bar(s) will be displayed at edge(s)
[10] You do not normally need to set the starting point and active area,
but set them only if the edge of 1 to 2 dots is cut off.
[11] Does the resolution setting for the PC (You can check it in
"Properties" of the PC) and the resolution output from the PC (You can
check it in "7.16.7 Input signal status [INPUT STATUS]") match? If
not, set the EDID and PC resolution manually.
Do the selected aspect ratio of the output resolution and that of the
connected sink device match? If not, set the aspect ratio of the sink
device.
Check the set aspect ratio of the input signals.
Check the monitor setting of the source device (such as 4:3, 16:9,
letter box and the like).
If a still image of interlace signals is input, the video may blink.
If interlace signals are input to a sink device that does not support
interlace signals, the video may blink. Check the output resolution of
the sink device.
If the monitoring function for no-signal input works, the dual monitor
function may not operate correctly. In this case, turn the monitoring
function "OFF".
If you set the HDCP output to "HDCP INPUT ONLY", some display
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
"ALWAYS".
If the bitmap resolution and output resolution are not matched, the
bitmap may be partially cut off or may not be displayed on the full
screen depending on settings of aspect ratio and display position. In
this case, set the aspect ratio and display position as necessary.
