Blackout at zero brightness
- Uses system gamma curves to black out the image at minimum hardware brightness and restores the image when brightness increases.
- Clearly labels software blackout which does not power off the external display or its backlight.
Recovery and cleanup
- Reopens the uniquely matched DDC connection after blackout and retries transient communication failures a bounded number of times.
- Restores original per-display color curves on normal exit and preserves newer system or application curves while preventing late operations from blacking out displays again.
