Abstract: A method for automatically adjusting pictures on a display device, by which a plurality of reference points and the corresponding slope values are stored in a memory of the display device. The reference points and the corresponding slope values, as well as the synchronous frequency and the image timing, set by a user are used by a microprocessor within the display to determine whether to adjust the picture frame and the display position of the pictures, so as to fit the preset display values by the user.

Abstract: A method of warming up a display device is performed by pressing at least one adjustment button placed on the front panel of the display device. When the adjustment button is pressed an image pattern is displayed so that the display device can perform the warming up process. The image signal is generated by an OSD controller within a CRT display device or a scalar within an LCD display device, so the display device does not need to connect to an image output device during the warming up process and the cost and time involved are accordingly both low.
