    Hello,

    The 988 can support pixel clock rates of up to 420 MHz over dual OLDI port. Could you share the video resolutions/display timing for this? This would include, Horizontal total, horizontal active, vertical total, vertical active, and refresh rate. 

    The Pixel clock rate, PCLK = Horizontal total (pixels) * Vertical total (pixels) * refresh rate (fps)
    and the maximum supported by the 988 OLDI output is 420 MHz.

    The images you attached are not loading, could you please share again? For further support for bringing up the 98x devices, please contact you local TI FAE.
    Best regards,
    Ikram
