monitor resolution.
The monitors that come with the system are DDC2A/B (Display Data

passes resolution and frequency information to the system. The
system interprets the data and sets up the proper refresh rate.

monitor is turned-on alone, or is turned-on and connected to a
powered-off system unit, the monitor LED presents amber blinking.

between the monitor and the system unit. Check the line
voltage, power cord, and continuity for the system I/O signal
cable before replacing the monitor. See "Monitor Port Signals"
