Interference or noise
appears on video.
When an optical I/O slot board is mounted, are optical fiber cable type,
standard, polishing method, and laying method correct?
Make sure that the both ends have LC connecter, the cable meets the
SFP module standard, and the polishing method is correct.
The optical loss occurs depending on scratches and dirt of connector
ends, bend radius, lateral pressure, and connection method of optical
fiber cables. Check the power budget.
Snow noise appears.
Since optical I/O slot board does not support QWXGA, snow noise
appears. Input another resolution.
You can check the resolution input signals in the LCD screen, and you
can set the EDID in order to control the resolution.
Deep Color signals are
not output.
Does the sink device support Deep Color?
If not, 24 bit/pixel (8 bit/component) is used even if signals are input in
Deep Color.
Since the optical output slot board does not support Deep Color,
signals are transmitted in 24 bit/pixel (8 bit/component).
Video blinks.
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.
－
Video edges
(up/down/right/left) are
cut out.
Some sink devices display input video in overscan, and the video may
be cut out. Check the display setting of the sink device.
－
Video is distorted
horizontally or
vertically.
Some sink devices display input video on full screen mode, and the
aspect ratio cannot be kept. Check the display setting of the sink
device.
With some resolutions, full-screen display cannot be avoided. In that
case, change the output resolution of the source device.
－
Black bars appear on
PC images.
Only part of the PC
image is displayed,
and the rest of the
images is displayed by
moving the mouse.
If the PC has the Panel Fit function, select
“Scale Full Screen”.
If the resolution that is set for the PC and the resolution that is actually
output from the PC are not matched, those problems may occur.
Check the resolution of the PC and the EDID resolution setting.
The dual monitor
function cannot be set
or it is canceled
automatically.
When the No-signal input monitoring function works, the dual monitor
function may not be enabled correctly. In this case, turn off this
monitoring function.
