Most modern monitors will switch to a power-saving mode if no video-input signal is received.This allows modern operating systems to turn off a monitor after a specified period of inactivity.
This also extends the monitor's service life. Some monitors will also switch themselves off
after a time period on standby.
Most modern laptops provide a method of screen
dimming after periods of inactivity or when thebattery is in use. This extends battery life andreduces wear.

Many monitors have other accessories (orconnections for them) integrated. This placesstandard ports within easy reach and eliminatesthe need for another separate hub, camera,microphone, or set of speakers. These monitorshave advanced microprocessors which containcodec information, Windows Interface drivers
and other small software which help in properfunctioning of these functions.
