After soft image stitching using the Camera Tuning Tool (CTT), color bars appear on some HD displays.
Step 1 On the CTT, disable video stitching. Alternatively, telnet to the telepresence host using its internal IP address and run bls enableMosaic 0 0.
The default internal IP address of the telepresence host is 172.16.21.10.
Step 2 Check the telepresence host version.
Step 3 Obtain the upgrade package corresponding to the telepresence host version. Use the CTT contained in the upgrade package to perform image stitching again.
Step 4 Save the video settings after successful image stitching.
The CTT version is incompatible with the telepresence system. As a result, no error messages are displayed when video dragging exceeds the predefined scope, which leads to data overflow and consequently color bars.
