    Can you send me the timing for your display. 

    THW =
    TVW =
    AHW =
    AVW =
    HBP =
    VBP =
    HSW =
    VSW =
    HFP =
    VFP =
    PCLK =

    Parameters are as follows：

    Parameters are as follows(PCLK=91.5MHz):

    THW = 2028
    TVW = 752
    AHW = 1920
    AVW = 720
    HBP = 32
    VBP = 21
    HSW =24
    VSW = 3
    HFP = 52
    VFP = 8
    PCLK = 91.5
    Bits_per_pixel = 24

    Regards,

    Zhen.

    Hi Zhen,

    I see the issue. Your PCLK is too high for internal oscillator. 948 can go up to 70 Mhz max frequency for PCLK.

    Are you able to run external PCLK with internal timing? Or external timing with external PCLK? If so, I have both of these scripts attached for you.
