Combined panel self-refresh (psr) and adaptive synchronization systems and methods

A source device comprising:

• an interface;
• and
• processor circuitry to execute instructions to cause the source device to:
• determine that video timing synchronization is to be maintained between the source device and the sink device while in a panel replay mode;
• while in the panel replay mode, enable a high-bandwidth communication link;
• transmit a first timing symbol sequence via the high-bandwidth communication link, the first timing symbol sequence to convey timing information to the sink device;
• and
• change a state of the high-bandwidth communication link .

• transmit a first timing symbol sequence via the high-bandwidth communication link, the first timing symbol sequence to convey timing information to the sink device;
