why is monitor light blinking
Offline Modes. Many modern monitors use LED blink codes to signal that they receive power and can operate properly but remain in a standby mode. In these situations, you may see a monitor's LED blink, turn yellow or some color other than green, or both. When you plug your monitor's power cord into a switched outlet on your CPU so turning on the computer powers up the monitor, you may see the display's LED blink periodically until you start up the system.
