Test Pattern Generator (No Sync Screen) (Hdmiout, Tpsout) - Lightware MMX6x2-HT200 User Manual

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 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.

6.4.6. Test pattern generator (no sync screen) (HDMIOUT, TPSOUT)

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
Clock source
Pattern
ATTENTION!
The Mode can be set individually on each port, but the Clock source and the Pattern are
common for the mirrored output port. E.g. the Clock source and Pattern settings are the
same on O1-O3 and O2-O4 output ports.
