    H-Total in Period is used for Horizontal period measured. 

    V-total (27M) in Period is Vertical period measured using 27MHz clock.

    Please check the H/V in Active(DE) section, if the resolution 1920*240 is what you are feeding into the 8842, then mostly it was taken correctly.

    Secondly, the Htotal(I) should be the same as your signals, is it’s Htotal 2796? (Vtotal(27M) doesn’t matter).

    Then please check the MIPI-RX to see if the lane and clock settings are correct and PIC Height is 240, if yes then it should work.

     

    Let me know if you required more details.

    Thank you.
