1 Verify computer signal by connecting a known-good monitor.
Then disconnect the known-good monitor and reconnect the
Apple Studio Display. Ensure the monitor’s video cable and
ADB cable are connected to the computer.
2 Adjust front panel brightness (it may be set too low).
3 If screen brightness has decreased over time, the most likely
condition is the backlights failing. The backlights have an
average life of 10,000 hours (about 40 hours per week for
five years. If the display is over a year old and you suspect
backlight failure, contact an Authorized Apple Dealer for
replacing the backlights.
