5.6.2. 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.
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.

5.6.3. Test Pattern Generator - No Sync Screen
The output ports can send a special image towards the sink devices for testing purposes.
The setting is available on output ports with the following parameters:
Mode
On: the test pattern is always sent to the output port.
▪
▪ Off: the test pattern generator is off.
▪ No signal: the test pattern generator is switched on if no video signal is switched to the given output
port.
Clock source
480p / 576p / Original video signal: the clock frequency of the test pattern.
▪
Pattern
▪ Red / Green / Blue / Black / White / Ramp / Chess / Bar / Cycle. Cycle setting means all the patterns
are changed sequentially approx. in every 2 seconds.
ATTENTION! The Mode can be set individually on each port, but the Clock source and Pattern settings are
the same on O1-O3 and O2-O4 output ports.
