Just like to confirm if ADV7511 has an integrated Test Pattern Generator?
The ADV7511 is HDMI transmitter and I believe it does not have test pattern generator.But HDMI Receivers ADV7611/ADV7619/ ADV7612 with ADV7511 HDMI transmitter will produce default color output in free Run mode.The color of the screen is user configurable.
Also we have ADV7850 transceiver which has internal color bar test pattern for composite and S-Video Processing. ADV8005 also has internal test pattern generator. ADV7625 and ADV8005 has in build OSD, so you can create your own test patterns using Blimp OSD tool and use it for testing purpose. In free run mode, it can be configured different resolutions from SD to 4K2K with different test patterns.
The documentations part for the parts that referred you can go through below link.
