5.7.1. 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.
Lightware's Frame Detector function works like a signal analyzer and makes it 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 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 directly on the signal and not retrieved only from the HDMI info frames.
