loss may occur due to network congestion. Jitter may occur due to information
reorganization of the transmission or receiving equipment, such as, delay
processing, retransmission mechanism or buffer overflow.
Noise devices, such as computers or fans, may make it difficult to hear each other's
voices clearly.
Wires may also cause this problem. Replace the old with the new cables, and then
reconnect to check whether the new cables provide better connectivity.
Check whether the near site camera is connected to the VC110 all-in-one unit
correctly.
Check whether camera is powered on, and the LED indicator illuminates green.
Check whether the camera is selected for the current video input source.
Check the screen layout to see whether the remote video image is shown in full
size.
Check whether the Display1 port of VC110 all-in-one unit is connected to the HDMI
port on the display device.
Check whether a PC is connected to the VC110 all-in-one unit.
Check whether the PC is sending a signal.
Check the call statistics to see whether the endpoint is sharing content.
Ensure that dual-stream is configured correctly. For more information, refer to
Dual-Stream Protocol on page 149.
Refer to your monitor‘s documentation for specific recommendations and instructions.
The following guidelines help prevent image burn-in:
Ensure that static images are not displayed for long periods.
Be aware that meetings that last more than an hour without much movement can
