Graphics system operation failure detection

A method for a detecting failure in a display system, the method comprising:

• generating commands to draw a checker pattern in an invisible area of a display, wherein the commands cause the checker pattern to alternate between a first pattern and a second pattern;
• generating display data for being rendered by the display from a drawn checker pattern;
• determining whether display data includes the checker pattern alternating between the first pattern and second pattern;
• and
• rebooting the display system in response to the checker pattern not alternating between the first pattern and second pattern.

A display system for detecting display failures, the display system comprising:

• a vehicle display for displaying display content;
• a cover obscuring a portion of the vehicle display to define an invisible area of the vehicle display that is invisible to a human user and a visible area of the vehicle display that is visible to the human user;
• a processor;
• memory including instructions that, when executed by the processor, cause the processor to:
• generate the display content for the invisible area and visible area of the vehicle display, wherein the display content for the invisible area includes a checker pattern that alternates between a first pattern and a second pattern;
• determine whether display data generated from the display content includes the checker pattern alternating between the first pattern and the second pattern;
• and
• reboot the display system in response to the checker pattern not alternating.
