A display device and a method of checking signals input to a display device. The display device includes a signal identifying unit, a signal checking unit, and a signal changing unit. The signal identifying unit receives an input signal and identifies the type of input signal that is received. The signal checking unit checks whether the identified input signal is abnormal. The signal changing unit switches from the checked input signal to a next input signal to be checked so that the signal checking unit can check whether the next input signal is abnormal, after the signal checking unit checks whether the input signal is abnormal. Accordingly, when a display device goes to an abnormal mode, one of input signals can be checked in the display device to automatically change to another signal according to the order of checking the signals, the time required to check the signals, and the number of times the signals are checked without manipulating an additional key.

A display apparatus having a display to display a picture thereon comprises a pivot sensor comprising a weight body, a housing in which the weight body is accommodated and movable as the display is pivoted, and a contact sensor placed in the housing and generating a sensing signal according to a pivoted angle of the display when contacting the weight body. A pivot sensing controller applies a predetermined driving voltage to the pivot sensor, and determines the pivot angle of the display on the basis of the sensing signal generated corresponding to the applied driving voltage. The pivot sensing apparatus requires a reduced number of pivot sensors and peripheral circuits to sense a pivot angle of a display panel. A display apparatus and system comprising the pivot sensing apparatus, and a method for sensing a pivot angle, are also disclosed.
