A method for detecting a synchronization signal of a display comprises: obtaining an actual V-sync frequency of the display, comparing the actual V-sync frequency with standard V-sync frequencies prestored in a standard synchronization signal table, and selecting a standard V-sync frequency as a candidate V-sync frequency so that difference between the candidate V-sync frequency and the actual V-sync frequency is within a first error range; obtaining an actual H-sync frequency of the display, comparing the actual H-sync frequency with standard H-sync frequencies in the standard horizontal synchronization signal sub-table which corresponds to the selected candidate V-sync frequency, and selecting a standard H-sync frequency as a correct H-sync frequency so that difference between the correct H-sync frequency and the actual H-sync frequency is within a second error range, thereby a resolution of the display is obtained. |
