A method and display apparatus of providing an advance screen saver warning is disclosed. The display apparatus includes a parameter set unit, a counter, and a controller. The parameter set unit initially predetermines a screen saver standby time and an advance screen saver warning time, and the counter counts a current system idle time during which no system input activity is detected. Then the controller activates an advance screen saver warning before activating a screen saver if the current system idle time is greater than or equal to a time difference between the screen saver standby time and the advance screen saver warning time, where the advance warning may be in the form of a warning window displayed on a display screen or a warning sound outputted through a speaker.
