Display synchronization

A method of operating a display panel comprising:

• receiving display data from a transmitter and rendering the display data on a display screen of a display panel, wherein the display panel is in a first clock domain and the transmitter is in a second clock domain which is derived separately from the first clock domain;
• generating a first display time code locally at the display panel;
• receiving a second display time code from the transmitter;
• comparing the first display time code and the second display time code;
• and
• adjusting a clock frequency of the display panel based on the comparing.

A tangible, non-transitory, computer-readable medium comprising instructions that, when executed by a processor, direct the processor to operate a display panel, the instructions to direct the processor to:

• receive display data from a transmitter, the display data to be rendered on a display screen of the display panel, wherein the display panel is in a first clock domain and the transmitter is in a second clock domain which is derived separately from the first clock domain;
• generate a first display time code locally at the display panel;
• receive a second display time code from the transmitter;
• and
• adjust a clock frequency of the display panel based on a comparison of the first display time code and the second display time code.
