If Dell monitor enters Power Save or goes blank after a period of immobility, just moving mouse or pressing a key will turn it on. This aspect is managed by power settings in operating system, and turned off or adjusted to permit for longer idleness before switching off.

Connection

Few PCs have many similar monitor outputs in various places that come out to work identically, but in its place create power problems in Dell flat panels. As it is simple to attach monitor to wrong output, this is always first place to check. If power button on monitor does not stay green, or switches colors after turning on, this is a likely cause. When offered with equal outputs, most consistent port is found on video card, not CPU.
