5.5.2. Frame Detector
The ports can show detailed information about the signal like full size
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.
Frame detector window
Lightware's Frame Detector function works like a signal analyzer and
makes possible to determine the exact 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 grey). Dark grey 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.
