Frame detector (on video input ports)
Input 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
Frame detector
this function, open Properties panel of the input port on which the
signal has to be checked. Click on Frame Detector button to show detailed timings.
Figure 7-9. The frame detector window
Lightware's frame detector function works like an input signal analyzer and makes
possible to determine the exact video format that is sent by the source, 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 incoming 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 grey). 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.
The listed values are measured in real time, and they are refreshed in every three
seconds. The results are listed in a table which can be exported into CSV file. Clicking on
the Refresh button triggers a new measurement.
