There is mipi signal output, but it is not displayed. The suspect is the format matching problem. How do we check it?

Georage,
can you check the status of "lock" of UB954? also register 0x73~0x76 is on line length and line count, is it correct? if NOT, it is the setting issue between the high speed link.

best regards,
Steven

You need read the register 0x73-0x76. before reading these registers, please configure the reg 0x4c firstly to select the correct input channel.

best regards,
Steven
