Diagnostic Tools
5.5.1.
Frame Detector
The ports can show detailed information about the signal like blanking intervals and active video resolution.
This feature is a good troubleshooter if compatibility problems occur during system installation. To access
this function, open the port properties window and click on
Frame detector
button.

video format that is present on the port, thus helps to identify many problems. E.g. actual timing parameters
may differ from the expected and this may cause some displays to drop the picture.
Frame Detector measures detailed timings on the video signals just like a built-in oscilloscope, but it is
much more easy to use. Actual display area shows the active video size (light gray). Dark gray area of the
full frame is the blanking interval which can contain the info frames and embedded audio data for HDMI
signals. Shown values are measured actually on the signal and not retrieved only from the HDMI info frames.
5.5.2.
Cable Diagnostics
The cable diagnostics is a useful tool to determine any cable related issues in case of TPS connection.
The estimated cable length and the quality of the link are measured periodically and the diagnostic window
showsthevaluesinreal-time.Ifthegreenbarshitthefirstlineinthemiddletheyturnintored.Itmeans
the number of the errors – during the extension – is higher than recommended. The link might be alive but
recovering of the received data is not guaranteed.
INFO:
Each bar represents a differential line in the CATx cable. The inappropriate termination of the cable
usually causes high error rates. Check the cable terminations or change the cable.
