4.8.3 SMPTE-Compatible Analog-Level Output With Sync Inserted on All RGB Channels
This is another SMPTE-compatible RGB output. This mode is very similar to the mode described in Section 4.8.2,
except the sync signals are inserted on all three channels. Now all three channels have the same analog output
format, during both the active video period and the sync period.
