1. A display apparatus comprising:
- a communication interface configured to receive a video signal from an external device;
a display; and
a controller configured to;
process the received video signal by using a preset setting value,in response to the processed video signal not meeting a preset condition, generate and provide a test signal, instead of the video signal, to the communication interface, for checking whether the display apparatus is abnormal or the received video signal is abnormal, based on a characteristic of the test signal,process the test signal by using the preset setting value, andin response to the display apparatus being normal according to a result of the checking the characteristic of the processed test signal, adjust the setting value and process the video signal with the adjusted setting value, andcontrol the display to display the processed video signal.

9. A method of controlling a display apparatus, the method comprising:
-
receiving, at a communication interface of the display apparatus, a video signal from an external device; processing, at controller of the display apparatus, the received video signal by using a preset setting value; generating and providing, at the controller, a test signal, instead of the video signal, for checking whether the display apparatus is abnormal or the received video signal is abnormal based on a characteristic of the test signal, in response to the processed video signal not meeting a preset condition; processing, at the controller, the test signal by using the preset setting value; adjusting, at the controller, the setting value and processing the video signal with the adjusted setting value, in response to the display apparatus being normal according to a result of the checking the characteristic of the test signal; and displaying, at a display of the display apparatus, the processed video signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory computer-readable recording medium having a program stored therein as a data structure, wherein a processor of a computer causes the computer to execute program to carry out a method of controlling a display apparatus, the method comprising:
-
receiving a video signal from an external device; processing the received video signal by using a preset setting value; generating and providing a test signal, instead of the video signal, for checking whether the display apparatus is abnormal or the received video signal is abnormal based on a characteristic of the test signal, in response to the processed video signal not meeting a preset condition; processing the test signal by using the preset setting value; adjusting the setting value and processing the video signal with the adjusted setting value, in response to the display apparatus being normal according to a result of the checking the characteristic of the processed test signal; and displaying the processed video signal.
