Issue 01 (2013-12-20)
Possible Cause
Contact and ask the
administrator of the remote
site to perform a local video
loopback test. If the video
quality is good, it indicates
that the video frame rate set at
the remote site is too high.
The video settings of the
RP100-55T are incorrect.
The video settings of the
display are incorrect.
The camera is faulty.
The resolution of the computer
that is used for the VGA input
at the remote site exceeds the
maximum resolution
supported by the local
RP100-55T.
The local VGA display is not
supported.
The capability of the VGA
display is limited. The
resolution or refresh rate of the
local SXGA output is too high
to be supported by the VGA
display.
The local RP100-55T supports
only certain combinations of
resolutions and refresh rates.
The combination of the
resolution and refresh rate set
on the computer that is used
for the VGA input, however,
is not supported by the
RP100-55T. Therefore, the
local site cannot display or
properly display the remote
computer desktop.
