NEC-Mitsubishi Monitor Power patch 1.0.1

NEC-Mitsubishi has identified a compatibility issue between some models of display monitors and some Apple Macintosh G4 computers that causes the display monitor to remain off after a restart or powering up after shutdown. On certain versions of the Mac OS ROM, this will only occur if the G4 has been in sleep mode. NEC-Mitsubishi has identified the cause as an incompatibility in the Mac G4s with OS 9.0.4 and Mac OS ROMs versions 4.9.1, 5.2.1 and 5.5.1, and Mac OS 9.1 Upgrade with Mac OS ROM 6.1. This causes "power off" commands to be sent to the monitor on shutdown and restart, however no matching "power on" command is sent instructing the monitor to wake up as the Mac powers up. The problem only appears on certain monitors because they support an optional industry standard alternate power command system that has been introduced on the new G4s. It is important to note that the monitor is functioning normally and is just following commands sent from the Mac. The following Mitsubishi monitors are affected by this issue:

• Diamond Pro 2045
• Diamond Plus 120
• Diamond Plus 200
• Diamond Plus 220
• Diamond Plus 730
• Diamond Pro 720
