PROBLEM TO BE SOLVED: To enhance productivity by enabling image plane adjustment of a multi-sink display device relative to various signals to be performed easily with high accuracy. SOLUTION: An image-plane adjustment function of an all-signal adjustment preset processing part 206 for a multi-sink display device 100 is used to obtain an adjustment result relative to one or a plurality of signals, digital errors in the adjustment result are corrected, then correlation data between reference adjustment signals and adjustment data to be written in a memory 102 in the multi-sink display device 100 is computed based on the corrected adjustment result, and the adjustment data to be written in the memory 102 in the multi- sink display device 100 correspondingly to the respective signals is computed by a computing part 204 based on the computed correlation data. An automatic computation preset processing part 205 writes the adjustment data computed by the computing part 204 in the memory 102 in the multi-sink display device 100 correspondingly to the respective signals via a selector switch 207, an adjustment part 201, and a digital control I/F 101. |
