Problem Check item
Interference or noise
appears on video.
If a long cable is connected for input or output, change the equalizer setting.
If a long cable is connected for input or output, replace it with a 5 m/16.4 feet
or shorter cable.
Even though a 5 m/16.4 feet cable can be connected since the VAC has
compensation circuit for digital input and output, it cannot deliver its full
performance depending on the cable quality and connected devices. If the
problem is solved by the replacement with a shorter cable, the signals may
have been deteriorated because of the long-distance transmission. IDK
provides high-quality cables, boosters, and cable extenders. Please contact
us as needed.
Transmission clock of Deep Color signals is faster than normal signals. If
poor-quality or long cable is connected at the time of signal input or output,
noise may appear on the video.
The color depth of input signals can be controlled in the EDID setting.
Video blinks. If interlace signals are input to a sink device that does not support interlace
signals, the video blinks. Check the supported 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, 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.
