Dear All

      Below link, it's said "Device default is 720p so with internal SRAM, you have to load manually".

    Hello,

    please refer to DS90UB949 Datasheet, Section "8.4.2.2 Dual Link Operation".

    Dual Link mode may be automatically configured when connected to a DS90UB948-Q1/DS90UB940-Q1, if the video meets minimum frequency requirements. Dual Link mode may also be forced using the DUAL_CTL1 register (0x5B)
