Diagnostic Tools
5.6.1. 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.
