Dear all

The default register of DS90UB949-Q1EVM is set to 720p. Now, I want to set to 1080p@60Hz, could you tell me how to set the registers ? Thanks.

Hello Hamzeh

I just don't know how to set to run 1080p, also don't know which registers.

Could you please show me all registers that can run 1080p video ?

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)
