| (54) | Display apparatus and control method thereof |
| (57) A display apparatus includes a signal input unit through which an image signal is
input, the image signal comprising a synchronization signal and an active signal;
an adjustment signal generating unit that generates an adjustment signal; a signal
processing unit that receives the adjustment signal and adjusts the image signal based
on the received adjustment signal; and a controller which analyzes the input signal
and controls the adjustment signal generating unit to change characteristics of the
adjustment signal if the adjustment signal does not lie within a blanking interval
between the synchronization signal and the active signal. With this configuration,
even when an image signal having a reduced blanking interval between the synchronization
signal and the active signal is input, the adjustment signal can be generated within
the blanking interval of the image signal, not within the active signal interval.
