Abstract: A method for automatically powering up a display and a display using the same are disclosed. When a display device is connected to power from power disconnection, a flag is set as a power-on status. It is then determined whether a display signal is received by the display device, wherein the display device presents an image according to the display signal. When the flag is the power-on status and the display signal is received by the display device, the display device is caused to power up and present the image automatically.
