Abstract: A display controller includes a first memory, a second memory and an address controller. The first memory stores first extended display identification data (EDID). The second memory stores second EDID. The address controller sets a predetermined address to one of the first memory and the second memory. The memory set with the predetermined address allows a source device to read the corresponding EDID.

Abstract: A communications apparatus includes at least a first processor logic unit obtaining a support band list, a second processor logic unit generating a frequency search list for a first operating band and a frequency search list for a second operating band listed in the support band list, and a third processor logic unit performing power scan and cell search according to the frequency search lists. The frequency search list includes information regarding operating frequencies located in the corresponding operating band to be searched. The second operating band includes one or more operating frequencies overlapped with that of the first operating band, and the one or more operating frequencies of the second operating band overlapped with that of the first operating band is/are listed only in one of the frequency search list for the first operating band and the frequency search list for the second operating band.
