摘要: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 synchronizationsignal table, and selecting a standard V-sync frequency as a candidate V-sync frequencyso 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 standardhorizontal synchronization signal sub-table which corresponds to the selected candidateV-sync frequency, and selecting a standard H-sync frequency as a correct H-syncfrequency 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 isobtained.
